This investigation was carried out from October 2011-June 2012 to determine the prevalence of Staphylococcus in milk and rate of contamination at farm and milk distribution tank in Alage Agricultural Technical Vocational Educational Training College. Milk samples (row) were cultured on sheep blood agar and incubated. The plates were examined for gross colony morphology, pigmentation and haemolytic characteristics at 24-48 h then presumptive colonies of Staphylococcus aureus was selected and sub cultured on nutrient agar and incubated. Then, bacteria were identified according to its Gram reaction, morphology and the catalase test, tube coagulase test (4 h), haemolysis, pigment production (golden yellow), mannitol and maltose fermentation were used. A total of 170 milk sample of cow were examined for bacteriological status of S. aureus, an overall 28.2% prevalence of Staphylococcus was .. View More»
