During a survey in Jakarta, Indonesia, 158 cultures of Salmonella oranienburg, consisting of two phage types, were obtained from 150 hospitalized patients with diarrhoea. Phage type I, though found notably in young children, was found in all age groups while phage type II was found almost exclusively in young children aged 0-7 years. Phage type I may produce a more severe clinical picture affecting all age groups alike, while phage type II may result in hospitalization of only the very young, who are more susceptible to dehydration. Phage type I was significantly more resistant than phage type II to the individual antibiotics: tetracycline, chloramphenicol, kanamycin and neomycin. However, there was no difference in their respective antibiotic resistance patterns as measured by disk and MIC assay. All cultures were sensitive to gentamicin and trimethoprim-sulphamethoxazole 1:19.  相似文献

The distribution of phage types was studied among 577 strains of Salmonella typhi from Indonesia. Chemotype, colicinogeny, and tetrathionate reductase activity were also studied for most of these strains. The current phage type formula for Java was determined to be: A, D2, D6, E1a, E2, M1, and 46, but two other large groups of strains were also found, I + IV and degraded Vi+ strains. Significant differences in S. typhi strain distributions were noted between two localities on Java with respect to phage type and tetrathionate reductase activity. Comparisons were made with past phage typing studies in Jakarta as well as with more recent studies in other parts of south-east Asia. Phage types A, D1, D2, and E1 persisted at a rather steady level in Jakarta for 28 years. Evidence was found for epidemiological links to European and Asian areas. Antibiotic resistance among these Indonesian S. typhi strains was rare.  相似文献
