[rift valley fever in madagascar in 1991. sero-epidemiological studies in cattle].rift valley fever (rvf) virus was detected for the first time in madagascar in 1979, but without any impact on human and animal populations. however, in 1990 and 1991, several outbreaks with massive cattle abortions were described. since that period, seroepidemiological surveys have been conducted on the east coast and in the highlands (outbreak areas), in the high cattle density regions, and in the national slaughter house in antananarivo. a high rvf igm antibody prevalence was detected in the ...19921301622
preventive treatment against toxocarosis in bovine calves.treatment of bovine calves 10-16 days old with an anthelmintic which is effective against immature toxocara vitulorum killed the parasites, there was no new infection and recontamination of the environment was precluded. when the management of the program was delegated to the livestock officers, approximately 3% of calves scheduled for treatment developed patent infections. the prevalences of toxocarosis on the different farms were correlated with annual rainfall, probably because the longer dry ...19921441182
plasmodium falciparum malaria transmission indices in a highland village of the ikopa river valley near antananarivo, madagascar.data are reported from a malaria survey carried out in june 1991 in the small village of ankadimbazinba, near miantso, about 45 km north-west of antananarivo (madagascar). the objective was to evaluate the level of transmission of p. falciparum by entomological, parasitological and serological indices. all indices were found consistent with the description of a focus of hyperendemic transmission dependent on the presence of an. funestus at high density, corresponding to more than 50 females per ...19911844515
anopheline ecology and malaria infection during the irrigation development of an area of the mahaweli project, sri lanka.a study on adult anopheline ecology and malaria vector incrimination was carried out from 1986 to 1989 during irrigation development in an area of the mahaweli project in eastern sri lanka. eleven potential vector species were collected resting indoors or by using human or bovid bait, and from light trap catches. overall, anopheles vagus (donitz), an. annularis (van der wulp), and an. subpictus (grassi) were the most prevalent, and an. culicifacies (giles) and an. barbirostris (van der wulp) wer ...19911877717
a serologic study of california serogroup bunyaviruses in sri lanka.a seroepidemiologic study of california (cal) serogroup viruses (genus bunyavirus, family bunyaviridae) was carried out on 952 human and 1,834 animal sera collected from different ecological zones of sri lanka (latitudes 5-10 degrees n, longitudes 79-82 degrees e). the sera were screened for neutralizing antibody to lumbo (lum), snowshoe hare (ssh), and trivittatus (tvt) viruses by plaque neutralization tests on vero cells. of 2,786 sera screened, 262 (9.5%) had antibody to one or more viruses t ...19911928574
[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
[rapid diagnosis of rabies by the elisa method. its application in madagascar: advantages and disadvantages].elisa technique in the rabies rapid diagnosis is compared with other methods used in the pasteur institute of madagascar (immunofluorescence, mouse inoculation, and histopathology). the results of the comparative study of 80 samples of suspect animals show that elisa sensibility is better than immunofluorescence one. sensibility, specificity and viability of elisa are comparable with those of the two confirmation techniques. in madagascar, elisa is adapted to testing samples not conserved in goo ...19902078080
pathology of natural infections of schistosoma spindale montgomery, 1906, in cattle.the pathology of natural schistosoma spindale infections in cattle in sri lanka was studied. hepatic lesions were moderate with periportal cell infiltration and periportal epithelioid cell granulomas within perilobular zones. submucosal and mucosal granulomas accompanied by cellular changes were present in the small and large intestine. two unusual observations included the migration of an adult worm from the mesenteric veins to the mucosa of the small intestine in one bull and the presence of e ...19902079559
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

the epidemiology of schistosoma spindale montgomery, 1906 in cattle in sri lanka.during 1988 and 1989, the mesenteric veins of 901 cattle were examined for the presence of schistosomes at the kandy slaughterhouse (sri lanka). the overall prevalence of infection was 31.2%. animals younger than 2 years were less infected (21.3%) than those older than 5 years (47.9%). based on the number of paired worms counted, three intensities of infection were recognized: low (1-20 pairs), moderate (21-100 pairs) and heavy (greater than 100 pairs). intensities increased with the age of the ...19911852491
the field response of sri lankan sandflies & mosquitoes to synthetic cattle-derived attractants.this study examines the effect of synthetic cattle-derived odours, presented with communicable diseases centre (cdc) miniature light traps for mosquitoes and also with sticky traps for sandflies, in sri lanka. the odours alone did not increase the trapping of mosquitoes and it is concluded that other stimuli, such as co2, must also be present to obtain a positive response. neither cdc light traps nor sticky traps were suitable for collecting large numbers of sandflies.19911688141
rift valley fever on the east coast of madagascar.in march 1990, a rift valley fever virus (rvfv) outbreak was suspected in the district of fenerive on the east coast of madagascar after an abnormally high incidence of abortions and disease in livestock. sera from humans and cattle were tested for rvfv antibodies by immunofluorescence assay (ifa) and elisa-igm capture. sera and mosquitoes collected in the same area were tested for virus isolation by tissue culture and suckling mouse intracerebral inoculation, and for antigen detection by an eli ...19911687082
prevalence of babesia bovis and anaplasma marginale at selected localities in sri lanka.sera were collected from a minimum of 20 cattle aged nine to 36 months at each of 14 localities in five climatic zones of sri lanka. sera were tested for antibodies to babesia bovis and anaplasma by an indirect fluorescent antibody test and a card agglutination test, respectively. antibodies to b. bovis and anaplasma were detected in all samples tested from each of 14 and 12 localities respectively. in general, prevalences were consistently high among localities below 1,200 m and lower and more ...19921306921
rift valley fever epizootic in the central highlands of madagascar.between february and april 1991, unusual numbers of bovine abortion around antananarivo (central highlands, madagascar) were reported by official veterinary services. rift valley fever (rvf) virus isolations were made from sixteen aborted foetuses and one dead calf in different foci. using monoclonal antibodies, the isolated viruses were found to be different from the 1979 rvf strains isolated in madagascar from mosquitoes and human laboratory infection, and closer to african rvf strains. in a b ...19921297176
