BACKGROUND Multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis are emerging worldwide. The Green Light Committee initiative supported programmatic management of drug-resistant tuberculosis in 90 countries. We used estimates from the Preserving Effective TB Treatment Study to predict MDR and XDR tuberculosis trends in four countries with a high burden of MDR tuberculosis:...

background: one of the fundamental issues of infectious disease treatment is drug resistance. the aim of the present study was to investigate the first-line anti-tuberculosis drug resistance rates and determine the risk factors related to multidrug resistant mycobacterium tuberculosis.methods: from march 2011 to september 2012, mycobacterial strains were collected from one hundred fifteen diagn...

Introduction: The emergence of Multi-drug Resistant Tuberculosis (MDR- TB) is a challenge for global control and prevention mainly in developing countries. Socio-economic conditions, social vulnerability, behavioral factors to be considered as risk identifying MDR-TB. objective the study was identify independent MDR-TB among patients. Methods: An unmatched Case-control conducted from January 20...

a hundred and five strains of salmonella havana were studied from the patients of pediatric hospital of tehran and tabriz during 1976-86. the sources of the strains in order to their frequency were from-stool, blood, spinal, fluid, wound and urine. from the epidemiological point of view salmonella havana is serotype of most non-typhoid salmonella. all of the strains had drug resistancy and most...

The emergence of pre-extensively drug-resistant tuberculosis (pre-XDR-TB) is a threat to TB control programs in developing countries such as Zambia. Studies Zambia have applied molecular techniques understand drug-resistance-associated mutations, circulating lineages and transmission patterns multi-drug-resistant (MDR) Mycobacterium tuberculosis. However, none has reported genotypes mutations a...

background: resistance to anti-tuberculosis (tb) drugs is a global problem. previous studies showed that the prevalence of primary mdr-tb is higher and has been increasing. the purpose of this study was to determine the primary drug resistance in strains isolated from patients with smear-positive of the new cases to anti-tb drugs. methods: in this cross-sectional study, 266 smear positive pulmo...

The objective of the study: in Tomsk Region, to establish frequency multiple drug resistance (MDR) mycobacterium tuberculosis (MBT) new patients with reference their HIV status and assess treatment outcomes. Subjects methods. presented results were obtained from a retrospective cohort study 788 who registered for MDR TB at Phthisiopulmonology Medical Center January 2017 April 2019. Results. In ...

The objective: to determine the frequency of resistance Mycobacterium tuberculosis (MTB) most effective anti-tuberculosis drugs in patients Republic Karelia, characterize cases amplification MTB drug during chemotherapy (CT). Subjects and Methods. cultures 1,137 were studied, received from 2016 2021, among them 634 (55.8%) had multiple (MDR). Among MBT with MDR, there was a high extensive (XDR)...

Pseudomonas aeruginosa (P. aeruginosa) possesses a plethora of virulence determinants, including the production biofilm, pigments, exotoxins, proteases, flagella, and secretion systems. The aim our present study was to establish relationship between biofilm-forming capacity, expression some important factors, multidrug-resistant (MDR) phenotype in P. aeruginosa. A total three hundred two (n = 3...
