Abstract. Following an outbreak of Rift Valley fever (RVF) in south‐eastern Mauritania during 1998, entomological investigations were conducted for 2 years the affected parts Senegal and Mauritania, spanning Sénégal River basin. A total 92 787 mosquitoes (Diptera: Culicidae), belonging to 10 genera 41 species, captured light traps. In Senegal, Culex poicilipes (41%) Mansonia uniformis (39%) most abundant species caught, whereas Aedes vexans (77%) Cx. (15%) predominated Mauritania. RVF virus...
Following the reemergence of Rift Valley fever (RVF) virus in southeastern Mauritania 1998, an entomological survey was undertaken boundary area Senegal to assess extent circulation. During this study, RVF (36 strains) isolated for first time from Culex poicilipes nature. The possible role Cx. as vector is discussed regarding its biology and ecology.
The bacteriological quality of bathing water is a major public health issue. aim this study to assess the correlation between and risk disease outbreaks. was prospective in nature, ran from June December 2022. Fifty-nine (59) samples were taken sources used for bathing. membrane filtration method direct inoculation used. In Mamou, results showed that EI E. coli exceeded WHO threshold values rivers streams, with 2/4 (20%) 8/11 (80%) respectively. Whereas Pita, Enterococci had these standards...
ABSTRACT Reverse transcriptase PCR (RT-PCR) for diagnosis of Rift Valley fever (RVF) was evaluated by using 293 human and animal sera sampled during an RVF outbreak in Mauritania 1998. Results the RT-PCR diagnostic method were compared with those virus isolation (VI) detection immunoglobulin M (IgM) antibodies. Our results showed that is a specific, sensitive tool early phase disease its do not differ significantly from obtained VI. Moreover, combined IgM antibody 100% concordance
The Rift Valley fever virus (RVFV) is a threat that must not be neglected, as the consequences of RVFV are dramatic, both for human and animal health. This zoonotic already has demonstrated real capacity re-emerging after long periods silence, observed in Barkedji (Senegal, West Africa) 2002. In this article we present 2nd emergence 1st manifestation 1993, time circulation during 2 consecutive years among mosquito populations Senegal. As part entomological surveillance program undertaken...
The circulation of a rather wide range pathogens natural-focal infectious diseases transmitted by ticks was detected in West Africa at different points time: Borrelia, Rickettsia, Coxiella , Crimean-Congo hemorrhagic fever (CCHF), Bhanja, and bluetongue viruses, etc. Current epidemiological epizootiological situation on the territory Republic Guinea is not entirely clarified. aim this work to identify genetic markers (RNA/DNA) disease agents samples Ixodidae collected Guinea, determine...
Objective of the study. This work was carried out to identify markers (antigen and RNA) CrimeanCongo hemorrhagic fever (CCHF) virus in samples from ticks, collected all landscape-geographical areas Guinea: Lower, Middle, Upper Forest, obtain up-to-date data on distribution pathogen country. Materials methods . Total 4276 specimens 8 species ticks 2016–2019 territory Republic Guinea were studied, which compiled into 1406 samples. Ectoparasites livestock animals, dogs, small mammals. Viral...
For a long time, the main problem with water intended for human consumption has been health, and this stems from existence of micro-organisms (bacteria, viruses, protozoa, parasites) that transmit many dangerous infections to humans. Vibrio cholerae is one these micro-organisms. Cholera severe acute diarrhoeal disease caused by cholerae, Gram-negative bacterium colonises warm, saline alkaline surface waters, often in association phytoplankton or zooplankton. The aim study was identify...
The most common anthropozoonoses on the African continent are coxiellosis and Rift Valley fever. It is known that detection of specific IgG antibodies in blood sera farm animals one indicators pathogen circulation a certain territory. aim work was to identify collected territory Republic Guinea pathogens zoonotic infectious diseases: coxiellosis, brucellosis, glanders, CCHF, West Nile fevers, using enzyme immunoassay (ELISA). Materials methods. A panel 970 samples from inhabiting all...
Acute febrile diseases kill more than 250,000 people annually in West Africa. Malaria and typhoid fever traditionally occupy most of the total structure registered fevers. However, these data do not fully reflect true overall disease patterns African region. This is due to fact that diagnosis mainly based on clinical signs infectious process, suggesting a certain number may be caused by arboviruses. The detection specific antibodies (ABs) pathogens blood sera residents particular area...
Introduction: The last few decades have seen the emergence of numerous human and animal infectious diseases worldwide. Among emerging re-emerging diseases, viral haemorrhagic fevers are a major public health problem. Objective: aim this study was to map distribution agents carrying Crimean-Congo fever virus (arbovirus-tica) in natural region Middle Guinea. Method: Two types analysis methods (RT-PCR ELISA) were used. prefectures Mamou, Dalaba Pita used as collection areas. Random sampling...
