- Abstract
This study included isolation and diagnosis of Coagulase Positive Staphylococci bacteria from clinical samples of (21) samples from the Teaching Hospital for Women and Children in Ramadi and included nasal swabs, Ear swabs, Normel skin swabs, Wound swabs, Urine Swabs and Abscesses. These isolates were diagnosed according to phenotypic and biochemical tests and vatic. After diagnosing the developing colonies, it was found the Gram-positive bacteria formed a percentage (71.42%) of the clinical samples out of the total isolates that gave growth on the culture media, and the Staphylococci positive for the plasma coagulase enzyme (Coagulase Positive Staphylococci) was found. (71.42%) of the total Staphylococci bacteria obtained during isolation and diagnosis of clinical samples and a type of Staphylococcus positive for coagulase (CPS), Staphylococcus. aureus, was diagnosed based on the Slide and Tube Coagulase Test. The sensitivity of CPS-positive staphylococcus to the antibiotic against the bacteria was tested and it was found that the most effective antibiotic against S. aureus bacteria was Azithromycin as well as the antibiotic Gentamycin, as indicated by S. aureus has demonstrated resistance to Erythromycin as well as Ciprofloxacin. The different conditions for the production of the plasma coagulase enzyme (Coagulase) for the bacterial isolate of local number (5) were studied, and it was noticed that there is a great similarity in these conditions except for some differences. The study and it was noticed that the appropriate temperature in the production of the enzyme for the local bacterial isolate number (5) is the temperature (35) C, and it was noticed that the pH that led to the increase in the production of the enzyme is (PH10). After (24hr) incubator, and the results were consistent in terms of good production of the enzyme in the mentioned isolation when using a incubator shaker at a speed (100) .
