ABSTRACT
To study the prevalence of methicillin resistant Staphylococcus aureus [MRSA] so that recommendation can be made for their prevention and control. Design: 350 Staphylococcus MINUS strains were isolated from Swvab/pus and other specimens randomly. Place and Duration: The samples were processed in the Department of pathology King Edward Medical Lahore College, during June 2000 to December 2000. Subject/The specimens from various types of infection sites suspected on clinical ground were processed by Standard methods and antibiotic susceptibility testing of all the isolates was done by using modified Kirby Bauer Disc diffusion technique. Result: Of these 350 positive cultures for Staphylococcus aureus, 135 were found to be methicillin resistant [38.5%]. This study shows a high prevalence of MRSA, which is of serious concern in Pakistan, In addition to the economic burden for antibiotic treatment MRSA Infections are serious threat to patients and a challenge for doctors

One hundred and thirty strains of Salmonella typhi were isolated from the blood of patients clinically suspected to be suffering from typhoid fever for the 5-year period from Jan 1995 to Dec. 2000. The blood cultures were taken in brain heart infusion broth. The isolates were identified based on morphological, biochemical and serological characteristics. The susceptibility of the strains was tested by disc diffusion tests as per standard methods. A high level of resistance to first-line drugs was observed. 43.85 percent strains of S. typhi revealed resistance to chloramphenicol, 42.3 percent to ampicillin, 46.15 percent to co-trimoxazole, 37.69 percent to Amoxicillin, 6.15 percent to ciprofloxacin, 0.77 percent to pefloxacin, enoxacin, and ofloxacin. No resistance to ceftriaxone and cefotaxime was observed
