Studies on forms of Certian Bacteria with Particular Reference to Urinary Tract Infections

The induction of each of 27 strains of bacteria under the influence of each of 10 antibiotics was investigated. The bacterial strains tested included: Proteus, vulgaris (2 standard strains, and 4 clinical isolates) ; Salmoella typhi (2 clinical isolates) Salmonella enteritidis (1 clinical iso¬late); Pseudornonas aeruginosa (5 clinical isolates); Klebsiella pneumonia (2 clinical isolates); Staphylococcus aureus (4 standard strains, and one clinical isolate); and Streptococcus faecalis (1 clini¬cal isolate) .Antibiotics used were: benzylpenicillin; ampicillin ; oxaoillin; methicillin; D-cycloserine vancomycin bacitracin; chloramphenicol, erythromycin, and griseofulvin.Induction was performed on a medium containing:yeast extract 4%, peptone 0.27 %, Beef extract 0.05%sodium. chloride 0.5%5 MgS04. 7 H2O 0.2%, sucrose 15% and agar 0.8% ; in the presence of 1000 mg/ml of the antibiotic.With respect to the efficiency of each antibio¬tic in induction the following observations
