CRISPR-based diagnostics are a new class of highly sensitive and specific assays with multiple applications in infectious disease diagnosis. SHERLOCK, or Specific High-Sensitivity Enzymatic Reporter UnLOCKing, is one such diagnostic that combines recombinase polymerase pre-amplification, CRISPR-RNA base-pairing, LwCas13a activity for nucleic acid detection.

Abstract Background Though Plasmodium vivax is the second most common malaria species to infect humans, it has not traditionally been considered a major human health concern in central Africa given high prevalence of Duffy-negative phenotype that believed prevent infection. Increasing reports asymptomatic and symptomatic infections individuals throughout raise possibility P. evolving evade host resistance, but there are few parasite samples with genomic data available from this part world....

Malaria is preventable and treatable when recommended interventions are properly implemented. Thus, diagnosis treatment focus on symptomatic individuals while asymptomatic Plasmodium infection (PI) plays a role in the sustainability of transmission may also have an impact morbidity disease terms anaemia, nutritional status even cognitive development children. The objective this study was to assess PI prevalence its relationship with known factors vulnerable but stratum population. A simple...

The majority of Plasmodium falciparum malaria diagnoses in Africa are made using rapid diagnostic tests (RDTs) that detect histidine-rich protein 2. Increasing reports false-negative RDT results due to parasites with deletions the pfhrp2 and/or pfhrp3 genes (pfhrp2/3) raise concern about existing strategies. We previously identified pfhrp2-negative among asymptomatic children Democratic Republic Congo (DRC), but their impact on diagnosis symptomatic is unknown. performed a cross-sectional...

Abstract Background While Plasmodium falciparum and vivax cause the majority of malaria cases deaths, infection by malariae other species also causes morbidity mortality. Current understanding these infections is limited in part existing point-of-care diagnostics that fail to differentiate them have poor sensitivity for low-density infections. Accurate diagnosis currently requires molecular assays performed well-resourced laboratories. This report describes development a P. diagnostic assay...

Abstract Plasmodium ovale curtisi ( Poc) and wallikeri Pow ) are relapsing malaria parasites endemic to Africa Asia that were previously thought represent a single species. Amid increasing detection of in sub-Saharan Africa, we performed population genomic study both species across the continent. We conducted whole-genome sequencing 25 isolates from Central East analyzed them alongside 20 published African genomes. Isolates predominantly monoclonal (43/45), with their genetic similarity...

The parasite species Plasmodium ovalecurtisi (P. ovalecurtisi) and ovalewallikeri ovalewallikeri), formerly known as ovale, are endemic across multiple African countries. These thought to differ in clinical symptomatology latency, but only a small number of existing diagnostic assays can detect distinguish them. In this study, we sought develop new for the detection differentiation P. by leveraging recently published whole-genome sequences both species.

In early 2016, we implemented a community-based maternal, newborn, and child health (MNCH) surveillance using mobile phones to collect, analyze, use data by village volunteers (VHV) in Kenge Health Zone (KHZ), the Democratic Republic of Congo (DRC). The objective this study was determine perceptions households, attitudes community volunteers, opinions nurses center administrative authorities towards for MNCH rural KHZ DRC.We used mixed methods combining phenomenological descriptive...

Abstract Background P. ovale spp. infections are endemic across multiple African countries and caused by two distinct non-recombining species, curtisi ( Poc ) wallikeri Pow ). These species thought to differ in clinical symptomatology latency, but existing diagnostic assays have limited ability detect distinguish them. In this study, we developed a new duplex assay for the detection differentiation of that can be used improve our understanding these parasites. Methods Repetitive sequence...

The burden of maternal and child mortality is high in the Democratic Republic Congo (DRC). While health workers (HWs) with adequate knowledge practice (MCH) are crucial to reduce this burden, skill level HWs charge MCH DRC currently insufficient. This study aimed assess towards Kasai Maniema, two provinces very ratios under-5 rates.
