RESUMEN
When nasopharyngeal secretions from 171 Australian Aboriginal children hospitalized with acute lower respiratory tract infections (ALRI) were cultured selectively for Streptococcus pneumoniae and Haemophilus influenzae, 136 (79.5%) and 151 (88.3%) children yielded 166 and 254 isolates of S. pneumoniae and H. influenzae, respectively. In colonized subjects multiple populations of S. pneumoniae (20% of carriage-positive patients) and H. influenzae (55%) were common. Pneumococci belonging to 27 types or groups were identified. H. influenzae serotype b colonized 16.4% of all children studied. More than one half of 152 children tested were excreting antibiotics at the time of admission to hospital. Significantly fewer children with serum antibiotic residues were colonized with S. pneumoniae than were antibiotic free children. Antibiotic usage had no measurable impact on the isolation rate of H. influenzae.

The demographic features of acute x sporadic viral hepatitis as diagnosed by specific markers of viral infection in four different cities in north and north-east India, were examined. Of 405 patients examined, 26 per cent had HB,Ag, 5.9 per cent IgM-anti-HAV antibody, and 8.4 per cent IgM-anti-HBc antibody. Hepatitis B occurred more frequently in male patients (76 per cent) compared to hepatitis A (54 per cent), and in the young adult age group (21-30 years), compared to the latter, which occurred predominantly in children (0-10 years). By using tests to detect HbsAg and IgM-anti-HBc antibody, this study found that hepatitis B accounted for 3 per cent and 8.8 per cent of clinically detected acute sporadic hepatitis in patients less than and older than 10 years of age respectively, which is in contrast with previously-reported rates from India. This study also suggests that many of the infections thought to have been due to HBV, may be due to NANB hepatitis virus. This study emphasizes the importance of specific laboratory tests to draw epidemiologic conclusions regarding hepatitis.
