This study discussed the prevalence of S. aureus in some hospitals in Port-Said governorate and the possibility impact of the S. aureus isolates from foods of animal origin on nosocomial infections by genetic relatedness between isolates from foods and infected patients.
The bacteriological examination of 355 samples reveals of S. aureus in 28 from 255 total samples taken from hospitals kitchens with percentage 11% and 48 S. aureus isolates from 100 swabs of infected patients with percentage 48%, the antibiotic sensitivity test of most isolates revealed multidrug resistant S. aureus strains.
Used random amplified polymorphic DNA (RAPD) patterns to determine genetic relatedness among S. aureus isolates that revealed genetic relatedness among the isolates and give indication about the possibility to impact of S. aureus isolates from foods of animal origin in human infections.
