| Summary: | Introduction. It is very important to know the resistant bacteria to common used antibiotics in our community. Staphylococcus coagulase positive was the main cause of infection in infectious disease. This study was done to demonstrate the pattern of resistance to batalactamase antibiotics among staphiococci. Methods. During a period of five month, 38 coagulase positive staphylococcus isolates were identified from various clinical specimens from 600 patients at the AI-Zahra university hospital (affiliated to IUMSHS). Results. Betalactamase production assays using rapid acidometric and iodometric tests showed that 78.9 percent and 73.6 percent of isolates were positive, respectively. The differnce in determination rate between acidometric and iodometric tests was not statistically significant. Moreover the acidometric test was cheaper and more easy to perform than iodometric test. In vitro sensitivity testing using the disc diffusion method showed that all of isolates were resistant to carbenicillin, ampicillin and amoxicillin, while 7.9 percent and 13.2 percent were resistant to cefazolin and cephalexin, respectively. Discussion. We recommend use of cefazolin, cephalexin and oxacillin for treatment of patients with staphylococcus infections. |
