RESUMO

Out of 210 faecal samples collected from children below 5 years attending different hospitals in Jammu and exhibiting clinical signs of diarrhoea, 41.9% samples were found positive for group A rotavirus by RNA-PAGE. Escherichia coli isolated in the study belonged to nine serogroups, out of which O69 was most frequent, being present in 12.38% samples. E. coli serogroups well recognised as enteropathogens viz. O69, O20 and O153 were present in 27.6% samples. Other bacterial pathogens associated with diarrhoea were present in 8.09% samples, out of which Shigella spp. was found in 4.76% samples followed by Salmonella spp. (2.38%) and Pseudomonas spp. (0.95%).

RESUMO

Isolation of an enterotoxic factor from cell-free-culture-supernatant of S. stanley was achieved to homogeneity using salt precipitation, dialysis and molecular seive chromatography through Sephadex G-100 and G-200 columns. The purified enterotoxic factor yielded a single protein band on polyacrylamide gel electrophoresis, induced antibodies in the rabbit and showed single band on agar gel precipitation. It induced fluid accumulation in the rabbit ligated ileal loop (RLIL) and was neutralized by the homologous antiserum. Antigenically it was not related to cholera toxin but with enterotoxin of other Salmonella serotypes. It also exerted dermatotoxic effect in the rabbit skin causing marked central necrosis with peripheral erythema.
