The in-vitro action of the sulphamethoxazole/trimethoprim combination (cotrimoxazole) against coliforms, Proteus spp, and Staphylococcus aureus was re-examined. In nutrient broth the components of cotrimoxazole did not produce bacteriostatic synergy against most sulphonamide-resistant and a significant proportion of sulphonamide-sensitive strains. Any bactericidal action appeared to be due to t...

The coliform bacterial population in the Grand Forks, N.Dak. sewage system was examined for multiple-antibiotic-resistant organisms over a 1-year period. Multiple-antibiotic-resistant coliforms were found to be common in the sewage, and their numbers remained fairly constant relative to the total coliform population throughout the year. Resistance to kanamycin, tetracycline, and ampicillin was ...

Calves were fed Escbericbia coli of bovine origin containing an R factor with resistance determinants found rarely in human and bovine populations. Some of these calves received tetracycline. Fecal samples from human subjects in daily contact with the calves were analyzed for the R factor, the bovine E. coli, and changes in the levels of tetracycline resistant coliforms. Crossover from the calv...

Water samples from clay storage jugs ("zeers") located in homes and at public watering stands ("sebeels") at streets, mosques, and schools were examined. Coliforms, fecal coliforms, and fecal streptococci were detected in 100, 69, 88, and 91.56% of the samples, respectively. The general microbiology of the water and some factors affecting microbial load were studied. The predominant bacterial g...
