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. Erythromycin and oxytetracycline were least effective.

Screening for HIV infection has been made mandatory for every unit of blood collected for transfusion in major cities of the country, having facilities for such screening. Results of HIV screening among blood donors received from the 4 Metropolitan cities of Delhi, Bombay, Calcutta and Madras have been analysed year wise from 1989 to 1991 to determine the magnitude and trends of HIV infection in different categories of blood donors and the seropositivity rates seems to be increasing over time. Universal coverage of HIV screening for donated blood has not been fully achieved and the justification and urgency for achieving complete coverage is highlighted.
