Background and Objective: Drug resistance to tuberculosis is continuously increasing and is a significant threat to tuberculosis control programs because afew effective drugs are present against Mycobacterium tuberculosis. Although isoniazid (INH) is the most effective drug against tuberculosis, resistance to this drug also develops readily. Mutations in katG, specially the Ser315Thr substituti...
Background and Objective: Extensive use of antibiotics in medicine has led to resistance of microorganisms in urinary tract infection (UTI) in both children and adults. Therefore, conducting studies on antibiotic susceptibility is needed for selection of antibiotics based on regional studies. Materials and Methods: During the year 2006 urine samples from all symptomatic patients admitted to...
Abstract Background and Objective: Staphylococcus aureus is an important opportunistic pathogen causing a wide range of infections in human .Most clinical isolates of S.aureus are resistant to a number of antibiotics. For appropriate antimicrobial therapy, this study was conducted to determine antibacterial drug resistance patterns of S.aureus isolates obtained from different clinical samp...
abstract background and objective: highly active antiretroviral therapy (haart) can effectively prevent the progression of hiv-1 replication and increase life expectancy. there are numerous causes of treatment failure and the leading one is drug resistance. thus, we aimed to determine the hiv rt gene drug resistance mutations in patients treated with antiretroviral medications. material and met...
Background: Drug-Resistant Tuberculosis (DR-TB) is one of the major public health issues globally. Zambia highly burdened by TB and multi-drug resistant TB. In this study, sputum samples obtained from new previously treated cases were examined for drug-resistant Mycobacterium tuberculosis (MTB). Methods: Sputum specimens processed using N-acetyl-L-cysteine-sodium hydroxide method, stained fluor...
This study investigated the resistance of various Salmonella strains to beta-lactam antibiotics. Salmonella Minnesota (36 strains) and Salmonella Heidelberg (24 strains) were isolated from broiler chickens and carcasses by the Disk Diffusion Test and resistance genes blaCTX-M-8, blaACC-1 and blaCMY-2 were detected by PCR. Of the 60 strains tested, 80% were resistant to at least one antibiotic. ...
