ABSTRACT
One hundred and thirty samples of cerebro spinal fluid were collected from patients admitted with suspected signs and symptoms of meningococcal meningitis (M. meningitis) during the period from January 1986 to April 1989 and were processed for gram's staining, cultivation and latex agglutination tests for detection of polysaccharide antigen in the CSF. Totally 41.5% of turbid and hazy spinal fluid were positive for N. meningitidis by smear examination. Only 24.6% were positive by culture but 61.5% of sample were positive by latex agglutination tests. All the strains were sensitive to all antibiotics except one strain which was resistant to penicillin but it was sensitive to rifampicin.

The serum samples were collected from 52 patients of acute viral hepatitis and 235 hospital staff from Kasturba Hospital for Infectious Diseases. HBsAg was detected in their sera by counter-immuno-electrophoresis (CIEP), reverse passive hemogglutination (RPHA) and by micro-enzyme-linked-immunosorbent assay (ELISA) technique. Among the patients, HBsAg was detected in 12 cases (23%) by CIEP, in 18 cases (34%) by RPHA and in 23 patients (45%) by ELISA. In the hospital staff, HBsAg was detected in 4 samples (1.7%) by CIEP, in 8 samples (3.5%) by RPHA and in 32 samples (13.5%) by ELISA. Thus ELISA was found to be the most sensitive technique in detecting HBsAg.

During the ten year study i.e. 1978 to 1987, out of 53,251 cases of suspected enteric fever, S.typhi was isolated from 4005 cases (7%) and S.para typhi 'A' from 1108 cases (2.5%). A total of 52 strains of S. typhi and 4 strains of S.para typhi 'A' were found to be resistant to chloramphenicol. Minimal inhibitory concentration was greater than 256 micrograms/ml of all the strains of S.typhi and S.para typhi 'A'.
