[the wesselsbron virus, a new arbovirus for madagascar].wesselsbron virus, an african arbovirus group flavivirus, has been isolated in 1989 for the first time in madagascar from aedes circumluteolus collected inside primary forest near the village of marovitsika. serological studies in man using haemagglutination inhibition test have permitted to think that wesselsbron virus have circulated quietly in madagascar. the detection of wesselsbron antibodies in lemurs sets the problem of the biological cycle.19901964039
observations on the pathogenicity for sheep and goats and the transmissibility of the strain of virus isolated during the rinderpest outbreak in sri lanka in 1987.the pathogenicity for sheep and goats of the virus strain that caused acute rinderpest in cattle and domestic buffalo in sri lanka after an interval of over 40 years has been examined. the results show that it can cause overt clinical disease in goats, but only mild or unapparent infection in sheep. the disease was transmitted from infected sheep to in-contact susceptible sheep and calves.19902316182

arbovirus infections in ceylon.the haemagglutination-inhibition test has been used to assess the frequency of arbovirus infections in the population of ceylon, by age-group, and also in some animals. the antigens used were: chikungunya, je, dengue 1, 2, 3, 4, and tahyna.the percentage of positive reactors to the group-b viruses ranged from 16.3% to 84.6% and was lower in the mountainous part of the country. infections with the chikungunya (group-a) virus were less frequent (from 0 to 37%) and were considered to be recent infe ...19695308700

a sensitive polymerase chain reaction based assay for the detection of setaria digitata: the causative organism of cerebrospinal nematodiasis in goats, sheep and horses.a sensitive pcr assay for the detection of setaria digitata has been developed. two oligonucleotide primers (17 nt) were designed from a previously cloned and characterized tandemly arranged repetitive sequence of setaria digitata. using these primers, it was possible to amplify small quantities (100 fg) of s. digitata genomic dna. a simple procedure, using proteinase k and non-ionic detergent np 40, was followed to process the host blood samples and mosquitoes harbouring l3 larvae. the sensitiv ...199910190866
[water and environment in the southwest of madagascar].the dry and arid southwest region of madagascar is not a desert but resembles the sahel region of west africa. the chronic water deficit is aggravated by the heat and constant winds that accelerate evapotranspiration on the permeable soils. the dryness occurs because the southwest region lies outside the main pluviogenic systems. erosion occurs at all seasons. in the winter the sun and winds are the main causes, while the rare storms are more conducive to run-off and to erosion than to absor ...199312286688
the origin and dispersion of human parasitic diseases in the old world (africa, europe and madagascar).the ancestors of present-day man (homo sapiens sapiens) appeared in east africa some three and a half million years ago (australopithecs), and then migrated to europe, asia, and later to the americas, thus beginning the differentiation process. the passage from nomadic to sedentary life took place in the middle east in around 8000 bc. wars, spontaneous migrations and forced migrations (slave trade) led to enormous mixtures of populations in europe and africa and favoured the spread of numerous p ...200312687757
aeromonas simiae sp. nov., isolated from monkey faeces.two aeromonas strains, ibs s6874(t) and ibs s6652, were isolated from the faeces of two healthy monkeys (macaca fascicularis) from mauritius that were kept in quarantine in the centre for primatology, strasbourg, france. phylogenetic analysis based on 16s rrna gene sequences showed that the two isolates formed an unknown genetic lineage within the genus aeromonas. the two isolates had nearly identical sequences (0.1 % nucleotide substitution) that were related closely to those of recognized aero ...200415023964
bluetongue virus in the french island of reunion.this paper records the results of a bluetongue virus (btv) serological survey and reports the first isolation of btv on the french island of reunion. in january 2003, the french island of reunion, located off the coast of madagascar, reported an outbreak of disease in cattle that resembled clinical bluetongue (bt) in sheep. the suspected causal agent was isolated and identified as epizootic haemorrhagic disease of deer virus (ehdv). however, because of the similarity in the clinical signs to tho ...200515778021
rift valley fever during rainy seasons, madagascar, 2008 and 2009.during 2 successive rainy seasons, january 2008 through may 2008 and november 2008 through march 2009, rift valley fever virus (rvfv) caused outbreaks in madagascar. human and animal infections were confirmed on the northern and southern coasts and in the central highlands. analysis of partial sequences from rvfv strains showed that all were similar to the strains circulating in kenya during 2006-2007. a national cross-sectional serologic survey among slaughterhouse workers at high risk showed t ...201020507747
prevalence of rift valley fever infection in ruminants in madagascar after the 2008 outbreak.a rift valley fever (rvf) outbreak occurred in madagascar from january to may 2008. the objectives of this study were (1) to assess the current and past circulation of rvf virus (rvfv) in livestock in madagascar and (2) to evaluate the extent and magnitude of the 2008 rvf outbreak in livestock. the results of a country-wide serosurvey conducted in august 2008 on small and large ruminants are reported here. the study included 3437 cattle and 989 small ruminants (227 sheep and 762 goats) sampled i ...201121395414
rift valley fever in ruminants, republic of comoros, 2009.to the editor: rift valley fever (rvf) is caused by a phlebovirus (family bunyaviridae) transmitted by a wide range of mosquitoes (1). this zoonotic disease is present in africa, the middle east, and madagascar. infections by rvf virus (rvfv) in ruminants cause massive abortions in livestock and high death rates in young animals, which result in major economic consequences. humans are infected by mosquito bites, contact, or inhalation of aerosols. rvf is frequently unapparent or mild for humans, ...201121762604
co-circulation of bluetongue and epizootic haemorrhagic disease viruses in cattle in reunion island.bluetongue virus (btv) and epizootic haemorrhagic disease virus (ehdv) in deer have already been isolated in reunion island and have caused more or less severe clinical signs in cattle (ehdv) or in sheep (btv), as observed in 2003. in january 2009, cattle in reunion island showed clinical signs suggesting infection by one or the other of these arboviral diseases. a study was set up to determine the etiology of the disease. analysis by reverse transcriptase-polymerase chain reaction (rt-pcr) perf ...201122005178
