ABSTRACT

We analysed the record of blood cultures carried out at the Armed Forces Institute of Pathology, Rawalpindi between 1996 and 2003. We isolated 477 Salmonella typhi and 410 S. paratyphi A from blood of patients suffering from typhoid fever. We observed a significant shift in the distribution and antimicrobial susceptibility of typhoid salmonellae. The isolation rate of S. typhi fell significantly while S. paratyphi A is emerging as a major pathogen. Resistance to conventional antityphoid drugs in S. typhi decreased dramatically from 80% to 14%, while in S. paratyphi A resistance increased from 14% to 44%. Susceptibility to the fluoroquinolones decreased in both. No resistance to third generation cephalosporins was detected

ABSTRACT

To determine the resistance pattern of Mycobacterium tuberculosis isolates in Rawalpindi-Islamabad. The study was carried out at the Department of Microbiology, Armed Forces Institute of Pathology, Rawalpindi between September 2000 and August 2002. We examined 1359 pulmonary and extra-pulmonary specimens from suspected cases of tuberculosis. The radiometric Bactec 460 TB system was used for culture and antimicrobial susceptibility testing. Mycobacterium tuberculosis was isolated from 325 clinical specimens. Antimicrobial susceptibility of the isolates was tested against the four first-line anti-tuberculous drugs [rifampicin, isoniazid, streptomycin and ethambutol]. Fifteen% of the isolates were resistant to a single drug, 28% were multi-drug resistant including 7% which were resistant to all the four drugs. The overall resistance against individual drugs was rifampicin 32%, isoniazid 37%, streptomycin 19% and ethambutol 17%. The increasing level of drug resistance among mycobacterial isolates in our population is most alarming. Strict implementation of control measures is required to combat this unfolding crisis
