Predominancy of Staphylococcus saprophyticus in urinary tract infections in the Women

Abstract: Background: It is well known that S.saprophyticus is the main causative agent of UTI in women especially young. Aim: This study is aimed to evaluate the predomeninacy of S.saprophyticus in urine of 90 women complaining from UTI infections as compared with other Staphylococcus isolates. Methods: Laboratory tests to identify S.saprophyticus are based on its resistance to the antibiotic Novobiocine, the absence of coagulase and hemolysin, and intense pigment production. Results: In this study it was possible to obtain 47coagulase-negative Staphylococcal (CONS) isolates (52.3) out of 90 urine samples. Out of 47 CONS isolates it has been found that S .saprophyticus was the predominant isolates which is 26 (55.4%) followed by S.epidermidis which was 11 isolates (23.3%). The least isolates were S.cohnii, which was 3 isolates only (6.4%). Concerning the distribution of the isolates according to age it has been found that S .saprophyticus were the highest 12 (25.4) among the age group of 18-24 years and also the incidence of all the species were the highest among the same group of ages i.e 18-24 years Antibiotic susceptibility testing against the commonly used antimicrobials showed multidrug resistance, which is more than 80% to penicillin. All isolates were sensitive to vancomycin and it is concluded that S. saprophyticus ranks the first position[26 (55.4%)] among the isolates and S.epidermidis rank the second position[11isolates (23.4%)]. Conclusions: All isolates were highly resistant to penicillin and completely sensitive to vancomycin.
