In the western literature, four G serotypes (G1-G4) of human rotaviruses have been found to be of a major epidemiological importance. During the analysis of rotavirus serotypes from faecal samples in Pune, over 50% of specimens could not be serotyped with the available monoclonal antibodies against G1-G4 serotypes. The results prompted to look for the(More)
Rotavirus specific immunoglobulin levels were estimated and compared between mothers undergoing delivery from two socio-economic groups (n = 56 each) by direct/capture ELISA. IgG geometric mean titers (GMTs) of cord blood/mothers serum at delivery were significantly higher in the higher socio-economic group (HSG) as compared to the lower socio-economic(More)
Neutralizing antibody (NAb) responses to different rotavirus serotypes were compared in 64 convalescent-phase serum samples from hospitalized rotavirus-positive children less than 2 years of age and their mothers. Compared to the child patients, the mothers showed significantly higher NAb positivity to animal rotavirus serotypes G3 simian (96.88%), G6(More)
Rotavirus specific, serum IgM/IgA/IgG levels among hospitalized children and their respective mothers were determined. Children were grouped as having rotavirus diarrhoea (RVD) and non-rotavirus diarrhoea (NRVD) on the basis of fecal excretion measured by ELISA and RT-PCR. Although IgM seropositivity was observed among children of both the groups, it was(More)
An epidemic of diarrhoea in Jawhar, a tribal area of Thane district, Maharashtra, India was investigated. Within a period of approximately 2 months 490 cases of acute diarrhoea were reported among children under 5 years of age, with a case fatality rate of 0.40%. Twenty-seven out of 39 (69.23%) rectal swabs/faecal specimens obtained from hospitalized(More)
