ABSTRACT
A study was conducted in 507 pregnant women of different parities, trimesters of pregnancy and age groups for finding out the colonisation rate of group B streptococci either in throat or vagina or from both sites. Incidence of carriage rate in throat was 4.73%, in vagina 9.66% and in both sites 12.03%. Age, parity, gestational period of women were not found to have any significant influence on the colonisation rate at different sites. Isolation rate of the organism was greatly enhanced using two selective media for isolation compared to using single selective medium or combination of non-selective media and a single selective medium.

450 hospitalised cases of hepatic and non hepatic disorders and 100 normal individuals were examined for serum Hepatitis B Surface antigen and Delta Virus antigen by ELISA to find out its association with different clinical disorders. 105 patients (23.3%) and 2 control (2%) were positive for HBsAG. 60 cases with jaundice (26%) were HBsAg positive. 65% of HBsAg positive jaundiced patients had serum bilirubin level more than 2 mg per dl with a mean SGPT level of 488 iu/L. Only two cases were positive for HDV antigen among 60 HBsAg positive jaundice patients indicating a lower rate of prevalence of infection (3.3%). 62 (59%) out of 105 HBsAg positive cases did not show any history of blood transfusion or surgical interference indicating a positive HBV transmission through needle prick during investigative procedures.

Root-canal infection is very common in India. Both aerobic and anaerobic organisms have been claimed for its aetiology. However, isolation of Capnocytophaga species from non-vital anterior teeth is sparse. In this study a solitary case of Capnocytophagal root canal infection is reported.

Fifty one strains of Salmonella typhi were isolated during the recent outbreak of enteric fever in and around Calcutta. Forty strains were multidrug resistant including Chloramphenicol. Minimum inhibitory concentrations (MIC) of Chloramphenicol was between 200 mcg per ml and 500 mcg per ml. All these strains were sensitive to Cephalexine, Gentamicin, Furazolidine and Ciproflexacin. Widal test was done in all the cases but the result was inconclusive.

The prevalence of different types of hepatitis virus was estimated in 185 hospitalized jaundiced patients. It was found that 41.08% were positive for HBs Ag by ELISA method. The jaundiced group was also tested for IgM antibody and for total antibodies (IgG and IgM) to HAV infection by ELISA method and 5.40% were found to be positive. All patients in the jaundiced group had serum bilirubin above normal values. It was, therefore, assumed that the rest 52.92% were suffering from Non A Non B virus infection.
