Résumé
Investigations were conducted for serological evidence of hepatitis B virus (HBV) and hepatitis D virus (HDV) infections in children suffering from acute viral hepatitis. A total of 52 serum samples were analysed by enzyme immunoassay. Of these, 18 (24%) were positive for hepatitis B virus markers and 34 (65.4%) were negative. Delta virus infection was detected in 6/18 (33%) hepatitis B patients. A significant finding was, that of the 34 patients negative for hepatitis B, 4 (12%) were positive only for HDV although the latter can only occur as a coexistent infection with hepatitis B virus. From the present study it may be inferred that delta virus infection is prevalent in children and absence of HBV markers does not rule out hepatitis D.

172 sera were tested for serological markers of hepatitis A, hepatitis B, hepatitis C and hepatitis D to define the aetiology of acute viral hepatitis by Enzyme immunoassays. The viral aetiology could be decided in 60.5% (104/ 172) of patients. Hepatitis B infection was present in 34.9%, hepatitis A in 10.5%, hepatitis C in 9.3% and hepatitis D in 5.8% of cases. Delta hepatitis associated with HBsAg positive hepatitis was detected in 10% (6/60) of the patients. The aetiology remained undecided in 39.5% of patients.

A total of 447 Shigella strains were isolated from stool samples during 1989-1991. Of these 270 (60%) were from children. Among the different species and serotypes Sh. flexneri 60 (13.4%) and Sh. sonnei Phage 139 (65%) were the most frequently isolated strains. 154 (34.4%) strains were resistant to three and 179 (40%) to more than three antibiotics. Some strains of Shigella were found to be resistant to furazolidine and neomycin.

10,468 CSF samples from cases of meningitis in different age groups were cultured during 1988-1991. Acinetobacter calcoaceticus was isolated in 12 (5.6%) of 211 positive cultures. The strain were 100% resistant to ampicillin, cotrimoxazole and tetracycline 50% resistant to cephazolin gentamicin and kanamycin but 100% susceptible to chloramphenicol.
