elaboration of a crude antigen elisa for serodiagnosis of caprine neosporosis: validation of the test by detection of neospora caninum-specific antibodies in goats from sri lanka.the protozoan parasite n. caninum is a major pathogen in cattle and dogs. however, clinical symptoms are occasionally described for other potential hosts. natural abortion in goats due to n. caninum has been rarely reported and only little data is available on the seroprevalence of n. caninum in this species. in the present study, 486 goats from sri lanka were tested in a crude antigen elisa for the presence of serum antibodies against n. caninum. additionally, the sera were analysed by n. canin ...200415567589
blood-feeding behavior of aedes albopictus, a vector of chikungunya on la réunion.chikungunya virus (chikv) has long been considered to be transmitted to humans by the human-biting mosquito aedes aegypti, especially in africa. however, the recent outbreak of chikv involved another vector, aedes albopictus, and serological data in the literature suggest that several species of domestic or human-related vertebrates can be contaminated by this virus. however, the role of ae. albopictus mosquitoes as potential enzootic vectors for chikv has not yet been evaluated. here we investi ...201019589060
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

usefulness of restriction fragment length polymorphism and spoligotyping for epidemiological studies of mycobacterium bovis in madagascar: description of new genotypes.tuberculosis is highly prevalent in cattle in madagascar. an epidemiological study based on genotyping of mycobacterium bovis and its transmission to humans was carried out. the restriction fragment length polymorphism (is6110 and dr markers) and spoligotyping were used to assess the genetic diversity of strains from different regions of madagascar. one of these strains was isolated from goat, the other strains were isolated from zebu cattle. nine is6110 profiles, 20 dr profiles and 12 spoligoty ...200616384662
[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
detecting emerging strains of tuberculosis by using spoligotypes.the w-beijing strain of tuberculosis has been identified in many molecular epidemiological studies as being particularly prevalent. this identification has been made possible through the development of a number of genotyping technologies including spoligotyping. highly prevalent genotypes associated with outbreaks, such as the w-beijing strain, are implicitly regarded as fast spreading. here we present a quantitative method to identify "emerging" strains, those that are spreading faster than the ...200617015836
excretion of cryptosporidium oocysts by goats in relation to age and season in the dry zone of sri lanka.pattern of cryptosporidium oocyst shedding in relation to age and season was investigated monthly from may 1999 to april 2000 in three groups (24 goats per group) of naturally infected goats (from 1 month of age). the three groups designated 1, 2 and 3 were studied for 12, 6 and 3 months, respectively. an association between cryptosporidium oocyst counts and age was demonstrated. in group 1, oocyst excretion in the first, second and fourth months of age were significantly higher than that in 6, ...200111445158
prevalence of cryptosporidium infection in goats in selected locations in three agroclimatic zones of sri lanka.the prevalence of cryptosporidium oocysts in the faeces of 1020 goats in three age categories was examined during 1999 in selected locations of three agroclimatic zones of sri lanka. the oocysts were demonstrated using the sheather's sucrose flotation method followed by staining with the modified ziehl neelsen technique. cryptosporidium oocysts were detected in animals from all agroclimatic zones with the highest prevalence of infection in the dry zone (33.6%) compared with 24.7 and 21.7% in the ...200011035227
