BACKGROUND Mycobacterium tuberculosis drug resistance is a major challenge to the use of standardized regimens for tuberculosis (TB) therapy, especially among previously treated patients. We aimed to investigate the frequency and pattern of drug resistance among previously treated patients with smear-positive pulmonary tuberculosis at the Korle-Bu Teaching Hospital Chest Clinic, Accra. METHOD...
ABSTRACT Background and Objectives: Acinetobacter baumannii is an opportunistic pathogen that affects different groups of people, especially intensive care unit (ICU) patients. The prevalence of infections caused by this bacterium is very high. Today, prevalence of infections caused by multidrug-resistant (MDR) and extreme-drug resistant (XDR) strains is increasing. This study aime...
BACKGROUND There is limited evidence that the DOTS (directly observed therapy, short course) strategy for tuberculosis (TB) control can contain the emergence and spread of drug resistance in the absence of second-line treatment. We compared drug-resistance levels between 1996 and 2001 in the south of Vietnam, an area with a well-functioning DOTS program. METHODS Sputum specimens were collecte...
The emergence of infections caused by multi- or pan-resistant bacteria in the hospital or in the community settings is an increasing health concern. Albeit there is no single resistance mechanism behind multiresistance, multidrug efflux pumps, proteins that cells use to detoxify from noxious compounds, seem to play a key role in the emergence of these multidrug resistant (MDR) bacteria. During ...
The grey mould fungus Botrytis cinerea causes losses of commercially important fruits, vegetables and ornamentals worldwide. Fungicide treatments are effective for disease control, but bear the risk of resistance development. The major resistance mechanism in fungi is target protein modification resulting in reduced drug binding. Multiple drug resistance (MDR) caused by increased efflux activit...
Although multidrug-resistant (MDR) tuberculosis (TB) is a major public health problem in Eastern Europe, the factors contributing to emergence, spread and containment of MDR-TB are not well defined. Here, we analysed the characteristics of drug-resistant TB in a cross-sectional study in Abkhazia (Georgia) between 2003 and 2005, where standard short-course chemotherapy is supplemented with indiv...
BACKGROUND & OBJECTIVES Multidrug-resistant tuberculosis (MDR-TB) has emerged as a significant global health concern. The most important risk factor for the development of MDR-TB is previous anti-tuberculosis therapy. Category II pulmonary TB includes those patients who had failed previous TB treatment, relapsed after treatment, or defaulted during previous treatment. We carried out this study ...
BACKGROUND Multidrug-resistant (MDR) tuberculosis can be acquired through de-novo mutation during tuberculosis treatment or through transmission from other individuals with active MDR tuberculosis. Understanding the balance between these two mechanisms is essential when allocating resources for MDR tuberculosis. We aimed to create a dynamic transmission model of an MDR tuberculosis epidemic to ...
conclusions antibiotic resistance gene cassettes may be carried on integron or other genetic elements. the purpose of this study was to detect integron or genomic islands involved in antibiotic resistance profile of the isolates of h. influenzae collected in this study. results of the twenty isolates, all (100%) were resistant to clindamycin, chloramphenicol and tetracycline, 95% to amoxicillin...
conclusions: this study detected multiple drug resistance in pseudomonas aeruginosa including resistance to β-lactams, aminoglycosides, and fluoroquinolones. therefore, identification of drug resistance patterns in p. aeruginosa and detection of pan-resistant producing isolates are of great importance in prevention and control of infections in burn center ward. background: serious infections by...
