epidemiology of visceral leishmaniasis in india.kala-azar has re-emerged from near eradication. the annual estimate for the incidence and prevalence of kala-azar cases worldwide is 0.5 million and 2.5 million, respectively. of these, 90% of the confirmed cases occur in india, nepal, bangladesh and sudan. in india, it is a serious problem in bihar, west bengal and eastern uttar pradesh where there is under-reporting of kala-azar and post kala-azar dermal leishmaniasis in women and children 0-9 years of age. untreated cases of kala-azar are ass ...199910416321
influence of topography on the endemicity of kala-azar: a study based on remote sensing and geographical information system.kala-azar, a fatal infectious disease in many indian states, particularly in bihar, west bengal, uttar pradesh, and jharkhand, is caused by the protozoan parasite leishmania donovani and transmitted by the sandfly vector phlebotomus argentipes. the vector is distributed all over the country but the disease is confined to particular zones since before the last century. in this study, parameters such as altitude, temperature, humidity, rainfall and the normalized difference vegetation index (ndvi) ...201020503185
sodium stibogluconate-sensitive visceral leishmaniasis in the non-endemic hilly region of uttarakhand, india.although visceral leishmaniasis (vl) is endemic in various parts of india, mainly bihar, west bengal and orissa, and neighbouring countries such as nepal and bangladesh, it is rarely reported from the hilly areas of india. we report on nine male vl cases from the non-endemic garhwal region of uttarakhand who were treated successfully with sodium stibogluconate. we conclude that sodium stibogluconate-sensitive vl is emerging in this region and that urgent and effective vector control measures may ...200717382981
breeding places of phlebotomus argentipes annandale and brunetti (diptera: psychodidae) in west bengal, india.a search for the breeding places of phlebotomus argentipes annandale and brunetti was undertaken in west bengal during 1988-1990. sugar flotation technique was applied for the isolation of larvae from the collected soil samples and emergence trap and sticky paper trap were used for the collection of adults. soil incubation method was followed for the collection of emerged adults from the soil sample. a total 131 soil samples were analysed by flotation technique which produced 19 immature stages- ...19911841217
ten years of kala-azar in west bengal, part i. did post-kala-azar dermal leishmaniasis initiate the outbreak in 24-parganas?following resurgence in bihar of epidemic kala-azar, outbreaks of the disease were identified simultaneously in two separate foci about 500 km apart in west bengal in 1980. while the outbreak in one of these foci, in northern west bengal, was the result of a direct extension of the bihar epidemic, the source of parasite in the other (in the village of bandipur in the south of west bengal) remained unknown until a case of nodulo-ulcerative post-kala-azar dermal leishmaniasis (pkdl) was located in ...19921638662
genetic heterogeneity among visceral and post-kala-azar dermal leishmaniasis strains from eastern india and sudan, some patients of visceral leishmaniasis develop post-kala-azar dermal leishmaniasis (pkdl) while majority will not. similarly, the clinical manifestations and treatment outcome are reported to vary from district to district and state to state in india. present study is focused on to find out the genetic variations between vl & pkdl causing strains. nuclear dna from 24 strains of leishmania donovani, isolated from patients of visceral leishmaniasis (18) and pkdl (6) was extrac ...200717027344
serological and molecular analysis of leishmania infection in healthy individuals from two districts of west bengal, india, endemic for visceral leishmaniasis.abstractseveral epidemiological studies have indicated the presence of asymptomatic infections with leishmania donovani in the indian subcontinent, where parasite transmission is considered anthroponotic. in india, such asymptomatic leishmania cases have been identified in the state of bihar. we explored here, the presence of asymptomatic leishmania infection among healthy individuals living in two districts in the state of west bengal, india, using serological and molecular tests. blood samples ...201728719266
