Isolation and Identification of Staphylococcus-aureus Bacteria from Local Meat Samples and Study of their Antibiotic Resistance

Abstract

Abstract The study included the collection of (50) samples of local red meat in the Iraqi markets, to isolate and diagnose the s-aureus bacteria contaminated with them. Several microscopic, morphological and biochemical tests were conducted on the bacteria, including the catalase and oxidase test, the urea test, the mannitol sugar fermentation test, and the plasma coagulation test, then confirmed the final bacterial diagnosis using the Vietek2 technique. The results showed positive bacteria for catalase, urea production, ability of bacteria to ferment mannitol sugar and plasma coagulation, but it was negative for oxidase test. A bacterial resistance test was conducted for a number of antibiotics, as the bacteria showed high resistance to many of the following antibiotics (Ciprofloxacin, Amoxicillin\Clavulanic acid, Pipepracillin, Cefotaxime, Ceftriaxon), and the bacteria showed high sensitivity by bacteria to many antibiotics, namely (Amikacin, Vancomycin, Imipenem, meropenem).
