Antimicrobial susceptibility testing on isolated gram positive and gram negative bacteria from localunpasteurized milk (Fura de nunu)

The availability of antibiotics to treat infectious diseases has radically improved human and animal well-being, and also to a minor degree in plant health, they are often used in rearing animals for food and this use among others leads to the creation of resistant strains of bacteria. As the genomes of bacteria, especially pathogens, have become increasingly available, the prospect of using them to identify new targets for antibiotic discovery has renewed interest in such investigations between the public sector and large pharmaceutical and biotechnology companies. In this study, antimicrobial susceptibility testing was carried out on the local unpasteurized milk popularly called Fura de nunu after isolating bacteria (both gram +ve and gram -ve) from it, the resistant ability and sensitivity of the isolates were determined upon testing with some standard available antibiotics. In the present study, nineteen isolates of E.coli were isolated from Fura de nunu tested from which six (31.6%) were resistant to Sulphamethoxazole/Trimethoprim, one (5.3%) resistance to Ciprofloxacin and none was resistant to Cefpodoxime and none was resistant to two or three at a time. It was found out that some were resistant to the testing while few isolates were sensitive.
