Abstract
Milk samples from a dairy farm were bacteriologically evaluated. High mean viable counts were recorded -2.0 X 109/ml for total mesophilic count, 1.9 X 105 /ml for coliforms and 7 X 104 / ml for staphylococci. The bacterial spectrum showed such pathogenic and food poisoning organisms like Escherichia coli. Staphylococcus awreus, Pseudomonas aeruginosa. Bacillus cereus, Clostridium perjringens and Salmonella typhymurium. Weakly DNAse postive isolates and the DNAse negatives tended to have higher percentages of mutants resistance to Streptomycin, Tetracyline and Penicillin G respectively than the DNAse positives. Albout 63 percent of the isolates with multiple resistance were weakly DNAse positives.
