Incidence of Coagulase Negative Staphylococcus Isolated from Mastitis Cows and Human Contact

This study aimed to throw the light on the incidence of coagulase negative staphylococcus (CNS) in clinical mastitis and its surrounded people and if there is a relationships between the incidence of CNS in mastitic cows and in surrounded peoples. The samples of human and animals collected from the Talaat Mustafa dairy farm located in Noubareia Alexandria Egypt at Cairo-Alexandria Desert Road (Private farm) and the worker act in this farm. In this study, a total number of 50 lactating Fresian cows were investigated for clinical mastitis. The pharyngeal swabs (50 samples) collected from the farmers that closely related and intact with the cattle. The age of these individuals ranged from 15 – 60 years for determination the relationships between the bacteria isolated from the milk and human. The number of pharyngeal swabs samples were 50 samples. The milk samples were examined bacteriologically: twenty out of 50 samples (40%) were positive for staphylococcus. Eigt out of 20 samples (40%) were coagulase positive staphylococcus while 12 out of 20 samples (60%) were coagulase negative staphylococcus. Fifteen out of 50 (30%) examined human samples were positive for staphylococcus. Seven out of 15 (70%) of samples were coagulase positive while 8 out of 15 (53%) of samples were coagulase negative staphylococcus. The coagulase negative staphylococcus isolates were highly sensitive to ciprofloxacin and amikacin while intermediate sensitive for ampicillin/fnlbacterin and gentamycin and the resistant to amoxicillin and trimethoprime+ sulphamethaxol.
