It is believed that the current prevalence of malaria in endemic areas reflects selection for the carrier form of sickle cell trait through a survival advantage. Malaria has been incriminated as a great cause of mortality in people with sickle cell disease (SCD). However, people with SCD, a high-risk group, do not benefit from free or subsisized malaria prevention and treatment in Cameroon unlike other vulnerable groups which may be due to insufficient evidence to guide policy makers. This study aimed at describing clinical and socio-demographic characteristics of patients with malaria, determining the prevalence of malaria in hospitalized children and in those with SCD and without, compare frequency of presentation of malaria related complications (using clinical and laboratory elements that define severe malaria) between children admitted for malaria with SCD and those without and finally, determing the risk factors for death in children admitted for malaria.
This was a retrospective analysis of admission records of children age 1 to 18 years with a confirmed malaria diagnosis admitted at the Laquintinie Hospital during January 2015 through December 2018. Clinical features, laboratory characteristics and outcome of malarial infections, stratified by SCD status were studied. Patients with HIV infection, malnutrition, renal failure and discharged against medical advice were excluded from the study. Data were analysed using Epi-info 7 software and analysis done. Chi square test, Odds ratios, CI and student’s t test were used to determine association between variables. Statistical significance was set at p-value ≤0.05.
The prevalence of malaria was lower among children with SCD than it was among children without SCD (23.5% vs 44.9%). Similarly, among those with a positive microscopy, the mean parasite density was significantly lower among children with SCD than it was among children without SCD (22,875.6 vs 57,053.6 parasites/ μl with t-value − 3.2, p-value 0.002). The mean hemoglobin concentration was lower in SCD as compared to non SCD (5.7 g/l vs 7.4 g/l, t-value − 12.5, p-value
Compliance to anti-TB treatment is crucial in achieving cure and avoiding the emergence of drug resistance. Electronic health (eHealth) interventions are included in the strategy to end the global Tuberculosis (TB) epidemic by 2035. Evidences showed that mobile messaging systems could improve patient adherence to clinic appointment for diagnosis and treatment. This review aimed to assess the effect of mobile-phone messaging on anti-TB treatment success.
All randomized controlled trial (RCT) and quasi-experimental studies done prior to August 26, 2019 were included in the review. Studies were retrieved from PubMed, EMBASE, Cochrane and ScienceDirect databases including, grey and non-indexed literatures from Google and Google scholar. Quality of studies were independently assessed using Cochrane Risk of Bias Assessment Tool. A qualitative synthesis and quantitative pooled estimation were used to measure the effect of phone messaging on TB treatment success rate. PRISMA flow diagrams were used to summarize article selection process.
A total of 1237 articles were identified, with 14 meeting the eligibility criteria for qualitative synthesis. Eight studies with a total of 5680 TB patients (2733 in intervention and 2947 in control groups) were included in meta-analysis. The pooled effect of mobile-phone messaging revealed a small increase in treatment success compared to standard of care (RR 1.04, 95% CI 1.02 to 1.06), with low heterogeneity (I2 = 7%, p
In recent decades, there has been a marked increase in the number of reported cases of pertussis around the world, and pertussis continues to be a frequently occurring disease despite an effective childhood vaccination. This study aims to determine the role of household contacts of children diagnosed with pertussis in Casablanca Morocco.
From November 2015 to October 2017, children suspected of whooping cough that consulted Ibn Rochd University hospital at Casablanca with their household contacts were enrolled in the study. Nasopharyngeal (NP) samples of the suspected children were analyzed by culture and RT-PCR. For the household contacts, NP and blood samples were collected and analyzed by RT-PCR and specific detection of pertussis toxin antibodies by ELISA, respectively.
During the study period, the survey was carried out on 128 infants hospitalized for pertussis suspicion and their families (N = 140). B. pertussis DNA was specifically detected in 73 (57%) samples, coexistence of B. pertussis and B. parapertussis DNA in 3 (2.3%) samples, coexistence of B. pertussis and B. holmesii DNA in 10 (7.81%) and only one (0.78%) sample was IS 481 RT-PCR positive without the possibility of determining the Bordetella species with the diagnostic tools used. Confirmations of Pertussis infection in household contacts by culture, RT- PCR and serology were 10, 46 and 39%, respectively.
B. pertussis DNA was confirmed in the infants as well in their mothers in 38% of the cases. Co detection of B. pertussis and B. parapertussis DNA in 2% and co-detection of B. pertussis and B. holmesii DNA in 4%. B. holmesii DNA alone was detected in 5 NP samples of index cases and their mothers.
The results of this study confirm that B. pertussis is still circulating in children and adults, and were likely a source of pertussis contamination in infants still not vaccinated. The use of RT-PCR specific for B. pertussis in the diagnosis of adults is less sensitive and should be associated with serologic tests to improve diagnosis of pertussis and contributes to preventing transmission of the disease in infants.
In India, Accredited Social Health Activists (ASHAs) deliver services for diagnosis and treatment of malaria, although unlicensed medical practitioners (UMPs) (informal health providers) are most preferred in communities. A cross sectional survey was conducted to: (i) assess knowledge and treatment-seeking practices in the community, and (ii) explore the diagnosis and treatment practices related to malaria of UMPs working in rural and tribal-dominated high malaria endemic areas of central India, and whether they adhere to the national guidelines.
A multi-stage sampling method and survey technique was adopted. Heads of the households and UMPs were interviewed using a structured interview schedule to assess knowledge and malaria treatment practices.
Knowledge regarding malaria symptoms was generally accurate, but misconceptions emerged related to malaria transmission and mosquito breeding places. Modern preventive measures were poorly accessed by the households. UMPs were the most preferred health providers (49%) and the first choice in households for seeking treatment. UMPs typically lacked knowledge of the names of malaria parasite species and species-specific diagnosis and treatment. Further, irrational use of anti-malarial drugs was common.
UMPs were the most preferred type of health care providers in rural communities where health infrastructure is poor. The study suggests enhancing training of UMPs on national guidelines for malaria diagnosis and treatment to strengthen their ability to contribute to achievement of India’s malaria elimination goals.
The intraerythrocytic development cycle (IDC) of the rodent malaria Plasmodium chabaudi is coordinated with host circadian rhythms. When this coordination is disrupted, parasites suffer a 50% reduction in both asexual stages and sexual stage gametocytes over the acute phase of infection. Reduced gametocyte density may not simply follow from a loss of asexuals because investment into gametocytes (“conversion rate”) is a plastic trait; furthermore, the densities of both asexuals and gametocytes are highly dynamic during infection. Hence, the reasons for the reduction of gametocytes in infections that are out-of-synch with host circadian rhythms remain unclear. Here, two explanations are tested: first, whether out-of-synch parasites reduce their conversion rate to prioritize asexual replication via reproductive restraint; second, whether out-of-synch gametocytes experience elevated clearance by the host’s circadian immune responses.
First, conversion rate data were analysed from a previous experiment comparing infections of P. chabaudi that were in-synch or 12 h out-of-synch with host circadian rhythms. Second, three new experiments examined whether the inflammatory cytokine TNF varies in its gametocytocidal efficacy according to host time-of-day and gametocyte age.
There was no evidence that parasites reduce conversion or that their gametocytes become more vulnerable to TNF when out-of-synch with host circadian rhythms.
The factors causing the reduction of gametocytes in out-of-synch infections remain mysterious. Candidates for future investigation include alternative rhythmic factors involved in innate immune responses and the rhythmicity in essential resources required for gametocyte development. Explaining why it matters for gametocytes to be synchronized to host circadian rhythms might suggest novel approaches to blocking transmission.

The development of vaccines for prevention of diseases caused by pathogenic species can encounter major obstacles if high sequence diversity is observed between individual strains. Therefore, the development might be restricted either to conserved antigens, which often are rare, or to multivalent vaccines, which renders the production more costly and cumbersome. In light of this complexity, we applied a structure-based surface shaping approach for the development of a Lyme borreliosis (LB) vaccine suitable for the USA and Europe. The surface of the C-terminal fragment of outer surface protein A (OspA) was divided into distinct regions mainly based on binding sites of monoclonal antibodies. In order to target the six clinically most relevant OspA serotypes (ST) in a single protein, exposed amino acids of the individual regions were exchanged to corresponding amino acids of a chosen OspA serotype. Six chimeric proteins were constructed and based on their immunogenicity four of these chimeras were tested in mouse challenge models. Significant protection could be demonstrated for all four proteins following challenge with infected ticks (OspA ST1, OspA ST2, and OspA ST4), as well as with in vitro grown spirochetes (OspA ST1 and OspA ST5). Two of the chimeric proteins were linked to form a fusion protein, which provided significant protection against in vitro grown spirochetes (OspA ST1) and infected ticks (OspA ST2). This article presents the proof-of-concept study for a multivalent OspA vaccine targeting a wide range of pathogenic LB Borrelia species with a single recombinant antigen for prevention of Lyme borreliosis.

Streptococcus suis serotype 2 is an important bacterial pathogen of swine and also an emerging zoonotic agent that may be harmful to human health. Although the virulence genes of S. suis have been extensively studied, the mechanisms by which they damage the central immune organs have rarely been studied. In the current work, we wanted to uncover more details about the impact and mechanisms of S. suis on specific populations of thymic and immune cells in infected mice. Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP)-biotin nick end-labeling (TUNEL) assays revealed that S. suis infection induced apoptosis in CD3+, CD14+ and epithelial cells from the thymus. S. suis infection resulted in a rapid depletion of mitochondrial permeability and release of cytochrome c (CytC) and apoptosis-inducing factor (AIF) through up-regulation of Bax and down-regulation of Bcl-xl and Bcl2 expression in thymocytes. Moreover, S. suis infection increased cleavage of caspase-3, -8, -9. Thus, S. suis induced thymocyte apoptosis through a p53- and caspase-dependent pathway, which led to a decrease of CD3+ cells in the thymus, subsequently decreasing the numbers of CD4+ and CD8+ cells in the peripheral blood. Finally, expression dysregulation of pro-inflammatory cytokines in the serum including interleukin (IL)-2, IL-6, IL-12 (p70), tumor necrosis factor (TNF), and IL-10 was observed in mice after S. suis type 2 infection. Taken together, these results suggest that S. suis infection can cause atrophy of the thymus and induces apoptosis of thymocytes in mice, thus likely suppressing host immunity.

The serine-glycine dipeptide lipid classes, including Lipid 430 and Lipid 654, are produced by the periodontal pathogen, Porphyromonas gingivalis, and can be detected in lipid extracts of diseased periodontal tissues and teeth of humans. Both serine-glycine lipid classes were previously shown to engage human and mouse Toll-like receptor 2 (TLR2) and to inhibit mouse osteoblast differentiation and function through engagement of TLR2. It is not clear if other lipids related to serine-glycine lipids are also produced by P. gingivalis. The goal of this investigation was to determine whether P. gingivalis produces additional lipid classes similar to the serine-glycine lipids that possess biological properties. P. gingivalis (ATCC 33277) was grown in broth culture and lipids were extracted and fractionated by HPLC. Lipids were separated using semipreparative HPLC and specific lipid classes were identified using LC-MS/MS and LC-MRM mass spectrometric approaches. Two glycine lipid classes were identified, termed Lipid 567 and Lipid 342, and these lipid classes are structurally related to the serine-glycine dipeptide lipids. Both glycine lipid classes were shown to promote TLR2-dependent TNF-α release from bone marrow macrophages and both were shown to activate human embryonic kidney (HEK) cells through TLR2 and TLR6, but not TLR1. These results demonstrate that P. gingivalis synthesizes glycine lipids and that these lipids engageTLR2 similar to the previously reported serine-glycine dipeptide lipids.

Stenotrophomonas maltophilia is a Gram-negative bacterium found ubiquitously in the environment that has historically been regarded as nonpathogenic. S. maltophilia is increasingly observed in patient sputa in cystic fibrosis (CF), and while existing epidemiology indicates that patients with S. maltophilia have poorer diagnoses, its clinical significance remains unclear. Moreover, as multidrug resistance is common among S. maltophilia isolates, treatment options for these infections may be limited. Here we investigated the pathogenicity of S. maltophilia alone and during polymicrobial infection with Pseudomonas aeruginosa. Colonization, persistence, and virulence of S. maltophilia were assessed in experimental respiratory infections of mice. The results of this study indicate that S. maltophilia transiently colonizes the lung accompanied by significant weight loss and immune cell infiltration, and the expression of early inflammatory markers including IL-6, IL-1α, and TNF-α. Importantly, polymicrobial infection with P. aeruginosa elicited significantly higher S. maltophilia counts in bronchoalveolar lavages and lung tissue homogenates. This increase in bacterial load was directly correlated with the density of the P. aeruginosa population, and required viable P. aeruginosa bacteria. Microscopic analysis of biofilms formed in vitro revealed that S. maltophilia formed well-integrated biofilms with P. aeruginosa, and these organisms colocalize in the lung during dual species infection. Based on these results, we conclude that active cellular processes by P. aeruginosa afford significant benefit to S. maltophilia during polymicrobial infections. Further, these results indicate that S. maltophilia may have clinical significance in respiratory infections.

Osteoarticular disease is a frequent complication of human brucellosis. Vaccination remains a critical component of brucellosis control but there are currently no vaccines for use in humans and no in vitro models for assessing safety of candidate vaccines in reference to development of bone lesions currently exist. While the effect of Brucella infection on osteoblasts has been extensively evaluated, little is known about the consequences of osteoclast infection. Murine bone marrow-derived macrophages were derived into mature osteoclasts and infected with B. abortus 2308, the vaccine strain S19, and attenuated mutants S19vjbR and B. abortus virB2. While B. abortus 2308 and S19 replicated inside mature osteoclasts, the attenuated mutants were progressively killed, behavior that mimics infection kinetics in macrophages. Interestingly, B. abortus 2308 impaired the growth of osteoclasts without reducing resorptive activity while osteoclasts infected with B. abortus S19 and S19vjbR were significantly larger and exhibited enhanced resorption. None of the Brucella strains induced apoptosis or stimulated nitric oxide or lactose dehydrogenase production in mature osteoclasts. Finally, infection of macrophages or osteoclast precursors with B. abortus 2308 resulted in generation of smaller osteoclasts with decreased resorptive activity. Overall, Brucella exhibits similar growth characteristics in mature osteoclasts compared to the primary target cell, the macrophage, but is able to impair the maturation and alter the resorptive capacity of these cells. These results suggest that osteoclasts play an important role in osteoarticular brucellosis and could serve as a useful in vitro model for both analyzing host-pathogen interactions and assessing vaccine safety.

Candida albicans is a pervasive commensal fungus that is the most common pathogen responsible for invasive fungal infection (IFI). With incidence of IFI on the rise due to increasing susceptible populations, it is imperative that we investigate how Candida albicans interacts with blood components. When stimulating either human or mouse whole blood with thrombin we saw a significant decrease in C. albicans survival. We then repeated Candida killing assays with thrombin-stimulated or unstimulated washed platelets and saw a similar decrease in CFU. To investigate whether killing was mediated through surface components or releasable products, platelets were pretreated with an inhibitor of actin polymerization (CytochalasinD, CytoD). CytoD was able to abrogate C. albicans killing. Moreover, dilution of releasates from thrombin-stimulated platelets showed that the toxicity of the releasates on C. albicans is concentration dependent. We then investigated C. albicans actions on platelet activation, granule release, and aggregation. While C. albicans does not appear to affect alpha or dense granule release, C. albicans exerts a significant attenuation of platelet aggregation to multiple agonists. These results illustrate for the first time that platelets can directly kill C. albicans through release of their granular contents. Additionally, C. albicans can also exert inhibitory effects on platelet aggregation.

Staphylococcus aureus is a gram-positive opportunistic pathogen that causes a variety of diseases. Bloodstream infection is the most severe, with mortality rates reaching 20-50%. Exopolysaccharide (EPS) from the probiotic, Bacillus subtilis, reduces bacterial burden and inflammation during S. aureus bloodstream infection in mice. Protection is due, in part, to hybrid macrophages that restrict S. aureus growth through reactive oxygen species, and to limiting superantigen-induced T cell activation, and IFN- production during infection. The decrease in IFN- production was observed within 24 hr after infection, and here, we investigated how EPS abrogates its production. We discovered that S. aureus uses a rapid, superantigen-independent mechanism to induce host IFN- and that this is mediated by IL-12 activation of NK cells. Furthermore, we found that EPS limits IFN- production by modulating host immunity in a TLR4-dependent manner, a signaling pathway that is required for EPS-mediated protection from S. aureus infection in vivo. We conclude that EPS protects hosts from acute bloodstream S. aureus infection not only by inducing macrophages that restrict S. aureus growth and inhibit superantigen-activated T cells, but also by limiting NK cell production of IFN- after S. aureus infection, in a TLR4-dependent manner.
Group B Streptococcal (GBS) infections in the United States are a leading cause of meningitis and sepsis in newborns. The CDC therefore recommends GBS screening for all pregnant women at 35–37 weeks of gestation and administration of intrapartum prophylaxis (in those that tested positive) as an effective means of controlling disease transmission. Several FDA approved molecular diagnostic tests are available for rapid and accurate detection of GBS in antepartum women.
In this study, we report a clinical comparison of the Xpert GBS LB assay and a novel FDA-cleared test, Revogene GBS LB assay. A total of 250 vaginal-rectal swabs from women undergoing prenatal screening were submitted to the University of Wisconsin’s clinical microbiology laboratory for GBS testing.
We found 96.8% of samples were concordant between the two tests, while 3.2% were discordant with a positive percent agreement of 98.0% and a negative percent agreement of 96.5% between the Revogene GBS LB assay and the GeneXpert GBS LB assay.
Overall, we report that both assays perform well for the detection of GBS colonization in pregnant women.

Five C. krusei isolates (susceptible and resistant) recovered from the urine of a kidney transplant patient treated with VRC 200mg/2x day for 20 days were studied. Eight unrelated clinical isolates of C. krusei were exposed in vitro to VRC 0.001 μg/ml, during 30 days. Development of VRC transient resistance occurred in vivo and induction of permanent resistance occurred in vitro. Mostly ABC1 and ERG11 genes were overexpressed and a homozygous T418C mutation in ERG11 gene was found.

We present a case of endocarditis wherein organisms cultured from different valve leaflets yielded different daptomycin susceptibility from each other, and from organisms obtained from peripheral blood culture. Genomic analyses showed mutations in mprF, purR and agrA. Pharmacokinetic simulations showed consistent activity of daptomycin+beta-lactam against all subpopulations. This represents an opportunity to understand S. aureus evolution and fitness in vivo on daptomycin therapy, and the role of beta-lactams to prevent selection of daptomycin resistant subpopulations.

Anti-malarial drugs have long half-lives, so clinical trials to monitor their efficacy require long durations of follow-up to capture drug failure that may only become patent weeks after treatment. Reinfections often occur during follow-up so robust methods of distinguishing drug failures (recrudescence) from emerging new infections are needed to produce accurate failure rate estimates. "Molecular correction" aims to achieve this by comparing the genotypes between a patient's pre-treatment (initial) blood sample and any infection that occurs during follow-up, ‘matching’ genotypes indicating a drug failure. We use an in-silico approach to show that the widely used "match counting" method of molecular correction with microsatellite markers is likely to be highly unreliable and may lead to gross under- or over-estimates of true failure rates depending on the choice of matching criterion. A Bayesian algorithm for molecular correction has been previously developed and utilized for analysis of in vivo efficacy trials. We validated this algorithm using in silico data and showed it had high specificity and generated accurate failure rate estimates. This conclusion was robust for multiple drugs, different levels of drug failure rate, different levels of transmission intensity in the study sites, and microsatellite genetic diversity. The Bayesian algorithm was inherently unable to accurately identify low-density recrudescence that occurred in a small number of patients, but this did not appear to compromise its utility as a highly effective molecular correction method for analysing microsatellite genotypes. Strong consideration should be given to using Bayesian methodology for obtaining accurate failure rate estimates during routine monitoring trials of antimalarial efficacy that use microsatellite markers.

A carbapenem-resistant Citrobacter spp. was recovered from routine screening of multidrug resistant bacteria. This isolate co-produced OXA-48 and OXA-198. OXA-48 was carried by the prototypical incL plasmid whereas OXA-198 was carried by a peculiar IncHI-type plasmid. This carbapenemase gene was inserted within a class 1 integron located on a conjugative plasmid. This report described the first occurrence of OXA-198 in Enterobacterales.

A key drawback to monitoring the emergence and spread of antimalarial drug resistance in sub-Saharan Africa is early detection and containment. Next-generation sequencing methods offer the resolution, sensitivity and scale required to fill this gap by surveilling for molecular markers of drug resistance. We performed targeted sequencing using molecular inversion probes to interrogate five Plasmodium falciparum genes (pfcrt, pfmdr1, pfdhps, pfdhfr and pfk13) implicated in chloroquine, sulphadoxine-pyrimethamine (SP) and artemisinin resistance, in two sites in Ghana. A total of 803 dried blood spots were prepared on filter-paper, from children aged between 6 months-14 years presenting with uncomplicated P. falciparum malaria at the Begoro district hospital in Begoro and the Ewim polyclinic in Cape Coast from 2014 to 2017. Thirteen years after the removal of drug pressure, chloroquine sensitive parasite strains, pfcrt K76 have increased nearly to fixation in Begoro in the forest area (prevalence = 95%), but at a slower rate in Cape Coast in the coastal region (prevalence = 71%, z=-3.5, P

The rise of Gram-negative pathogens expressing metallo-β-lactamases (MBLs) is a growing concern, threatening the efficacy of β-lactam antibiotics, in particular, the carbapenems. There are no inhibitors of MBLs in current clinical use. Aspergillomarasmine A (AMA) is an MBL inhibitor isolated from Aspergillus versicolor with both in vitro and in vivo ability to rescue meropenem activity in MBL-producing bacteria. Here we systematically explored the pairing of AMA with six β-lactam antibiotic partners against nineteen MBLs from each subclass (B1, B2, B3). Cell-based assays with Escherichia coli and Klebsiella pneumoniae showed that bacteria producing NDM-1 and VIM-2 of subclass B1 were the most susceptible to AMA inhibition, whereas bacteria producing CphA2 and AIM-1 of subclasses B2 and B3, respectively, were the least sensitive. Intracellular antibiotic accumulation assays and in vitro enzyme assays demonstrated that the efficacy of AMA/β-lactam combinations did not correlate with outer membrane permeability or drug efflux. We determined that the optimal β-lactam partners for AMA are the carbapenem antibiotics, and the efficacy of AMA is linked to the Zn2+ affinity of specific MBLs.
