ABSTRACT
We investigated the levels of Staphylococcus aureaus antibiotypes in Mualgo Hospital; toward effective control antibiotic drug resistance in the country. One hundred and elven (n=111) strains of Staph. aureus were tested to fourteen (n=14) antibiotics using stokes method. The obtained resistance profiles were analyzed by WHOBET5 computer software. forty-six (n=46) different antibiotypes were detected. These were further subdivided into three major categories:- 1. Methicilin Resistant - methicilin Suscpetible Staphylococcus aureus (MSSA); 2. Methicillin Resistant Staphylococcus aureus (MR-MSSA) and 3. Methicillin Resistant Staphylocossus aureus (MRSA). These categories were associated with 4; 28 and 14 antibiotypes respectively. One of the antibiotypes did not show any resistance to the tested drugs; while others expressed resistance mechanisms. We noted that MSSA; MR-MSSA and MRSA antibiotypes did not show any resistance to the tested drugs; while others expressed resistance to one or more (up to 11) antibiotics. This result reflects large number of resistance mechanisms. We noted that MSSA; MR-MSSA and MRSA antibiotypes expressed 0-1; 2-7 and 4-11 resistance mechanisms respectively. Of significance; the medical wards were source of 24of the MR-MSSA and MRSA strains. The predominating antibiotypes showed resistance to many common well established drugs (Trimethoprim; Tetracycline; Chloramphenicol; Erythromycin; Gentamicin and Methicillin) as well newer drugs Sodium Cefuroxime and Ciprofloxacin. The increased number of Staph. aureus resistant antibiotypes reflected uncontrolled antibiotic usage. This problem call for increased vigilance and proper use of bacterial antibiotics. In this connection; the last - line drugs methicillin; Telcoplanin and Vocomycin should be properly administered in order to prolong and maintain their use
