PSEUDOMONAS AERUGINOSA AND STAPHYLOCOCCUS AUREUS PROFILE IN SOME DAIRY FARMS

The purpose of the current study was to evaluate the degree of contamination of dairy farms with both Pseudomonas aeruginosa and Staphylococcus aureus , in which, a total of 150 swab samples were collected from 3 different dairy farms (50 each) distributed in Assiut governorate (farm A) and El-Minia governorate (farms B & C), Egypt. The swabs were taken from different locations in the dairy farms such as teats of dairy animals, milking machines, workers' hands and stanchions, etc. All the samples were examined for detection of Ps. aeruginosa (conventionally biochemical followed by MICROBACT™ identification kits) and for Staph. aureus (coagulase +ve). The obtained results revealed the overall incidence of Ps. aeruginosa as 14%, 2% and 4% in farms A, B & C, respectively; while, the incidence of Staph. aureus was 4%, 30% and 4%, respectively. In conclusion, the profile of both Ps. aeruginosa and Staph. aureus among the examined dairy farms is highlighting the hygienic state of each farm separately.
