Abstract Since 1990, South Asia has experienced a resurgence of kala-azar (visceral leishmaniasis). To determine risk factors for kala-azar, we performed cross-sectional surveys over 3-year period in Bangladeshi community. By history, active case detection, and serologic screening, 155 2,356 residents had with onset from 2000 to 2003. Risk was highest persons 3–45 years age, no significant difference by sex seen. In age-adjusted multivariable models, 3 were identified: proximity previous...
The appearance of bluetongue virus (BTV) in 2006 within northern Europe exposed a lack expertise and resources available across this region to enable the accurate morphological identification species Culicoides Latreille biting midges, some which are major vectors pathogen. This work aims organise extant taxonomic knowledge into database produce an interactive key for females Western Palaearctic (IIKC: Interactive Culicoides). We then validated IIKC using trial carried out by six...
Rift Valley fever (RVF) is a vector-borne disease transmitted by broad spectrum of mosquito species, especially Aedes and Culex genus, to animals (domestic wild ruminants camels) humans. endemic in sub-Saharan Africa the Arabian Peninsula, with periodic epidemics characterised 5-15 years inter-epizootic periods. In last two decades, RVF was notified new African regions (e.g. Sahel), occurred more frequently low-level enzootic virus circulation has been demonstrated livestock various areas....
Given the risk of zoonotic disease emergence, including new SARS-CoV-2 variants COVID-19, rapid diagnostic tools are urgently needed to improve control spread infectious diseases. A one-pot triplex real-time RT-LAMP (reverse-transcription-loop-mediated isothermal amplification) assay, based on two regions genome SARS-CoV-2-specifically Orf1ab and N genes-along with one internal control, human RNase P gene, was developed. The multiplexing relies distinct melting peaks produced during an...
Longitudinal investigations of an adult male population Kenyan car washers who have heavy and quantifiable occupational exposure to Schistosoma mansoni cercariae revealed that some individuals develop resistance reinfection while others remain highly susceptible. We sought characterize immune correlates associated with host protection in this population. Previous studies demonstrated association peripheral eosinophilia schistosomes. Thus, we investigated the relationship between percentage...
In southern Europe, orbiviral diseases such as bluetongue (BT) have been assumed to largely transmitted by the classical Afro-Asian vector Culicoides imicola Kieffer (Diptera: Ceratopogonidae). Recent outbreaks occurred in regions where C. is normally absent, supporting theory that other species belonging Obsoletus or Pulicaris complexes may play a role BT virus transmission. Investigations of ecology within former group are hampered females member being extremely difficult separate...
Abstract Rift Valley fever threatens human and animal health. After a case was confirmed in Comoros 2007, 4 serosurveys among ruminants Mayotte suggested that virus had been circulating at low levels since 2004, although no clinical cases occurred animals. Entomologic ecologic studies will help determine outbreak potential.
Rift Valley fever (RVF) is a zoonotic arboviral disease that threat to human health, animal health and production, mainly in Sub-Saharan Africa. RVF virus dynamics have been poorly studied due data scarcity. On the island of Mayotte Indian Ocean, off Southeastern African coast, has present since at least 2004. Several retrospective prospective serological surveys livestock conducted over eleven years (2004–15). These are collated presented here. Temporal patterns seroprevalence were plotted...
Understanding the demographic history and genetic make-up of colonizing species is critical for inferring population sources colonization routes. This main interest designing accurate control measures in areas newly colonized by vector economically important pathogens. The biting midge Culicoides imicola a major orbiviruses to livestock. Historically, distribution this was limited Afrotropical region. Entomological surveys first revealed presence C. south Mediterranean basin 1970s. Following...
Abstract. Biting midges of the genus Culicoides (Diptera: Ceratopogonidae) play important roles in transmission viral diseases affecting wild and domestic ruminants horses, including Bluetongue (BT) African horse sickness (AHS) respectively. In southern Europe, BT has been largely transmitted by classical Afro‐Asian vector imicola Kieffer. However, other species such as C. obsoletus Meigen, scoticus Downs & Kettle pulicaris Linné may also be involved BTV transmission. As a consequence...
Abstract Antibodies against bluetongue virus were detected in cattle, sheep, goats, and camels Algeria 2008. epizootic hemorrhagic disease but antibodies African horse sickness not horses mules. Epizootic northern Africa poses a major risk for the European Union.
Rift Valley fever virus (RVFV) is an arthropod-borne phlebovirus reported to be circulating in most parts of Africa. Since 2009, RVFV has been suspected continuously the Union Comoros. To estimate incidence antibody acquisition Comorian ruminant population, 191 young goats and cattle were selected six distinct zones sampled periodically from April 2010 August 2011. We found estimated 17.5% (95% confidence interval (CI): [8.9–26.1]) with a significant difference between islands (8.2% Grande...
Mayotte is an island located in the Mozambique Channel, between and Madagascar, South Western Indian Ocean region. A severe syndrome of unknown aetiology has been observed seasonally since 2009 cattle (locally named "cattle flu"), associated with anorexia, nasal discharge, hyperthermia lameness. We sampled blood from a panel those severely affected animals at onset disease signs analysed these samples by next-generation sequencing. first identified presence ephemeral bovine fever viruses...
Rift Valley fever (RVF) is a mosquito-borne viral zoonosis caused by the virus (RVFV) that can infect domestic and wild animals. Although RVFV transmission cycle has been well documented across Africa in savanna ecosystems, little known about its tropical rainforest settings, particularly Central Africa. We therefore conducted survey northeastern Gabon to assess circulation among Among 163 wildlife samples tested using RVFV-specific RT-qPCR, four ruminants belonging subfamily Cephalophinae...
