While conducting a leprosy survey in an urban slum in Pune 45 cases of leprosy were detected in a population of 4915 and only 7 of these cases had some disability. Disability rate in the leprosy cases was 15.56 percent, and maximum number had Grade 2 disability of hands or feet. Disability was higher in the higher age groups, males, Hindus, widower/widows, unemployed and lower socio-economic classes. Majority of the cases had a very low Disability Index DI (2) between 0.10 to 0.69 which is heartening and proves the successful implementation of the National Leprosy Eradication Programme.

A total of 82 strains of Salmonella belonging to 17 different serotypes recovered from foods of animal origin were in this study. Out of 39 cell free culture supernatants (CFCS), tested for enterotoxigenicity, 26 (66.67%) were positive in rabbit ileal loops. None were found positive for enterotoxigenicity in infant mouse model. According to the disc diffusion methods of testing, gentamycin, nalidixic acid and chloramphenicol were found to be most effective against Salmonella organism.
