This cohort study assessed drug susceptibility testing (DST) patterns and associated treatment outcomes from Transnistria, Moldova, from 2009 to 2012. Of 1089 newly registered tuberculosis (TB) patients with available DST results, 556 (51%) had some form of drug resistance, while 369 (34%) had multidrug-resistant TB (MDR-TB). There were four cases of extensively drug-resistant TB. MDR-TB patien...

BACKGROUND The World Health Organisation (WHO) defines Russia as one of the 22 highest-burden countries for tuberculosis (TB). The WHO Directly Observed Treatment Short Course (DOTS) strategy employing a standardised treatment for 6 months produces the highest cure rates for drug sensitive TB. The Russian TB service traditionally employed individualised treatment. The purpose of this study was ...

BACKGROUND Multidrug resistance is the main obstacle for hepatocellular carcinoma (HCC) treatment. miR-32-5p is involved in HCC progression but its function in multidrug resistance is still unclear. Here we aim to find out the function of miR-32-5p in inducing multidrug resistance and its underlying mechanisms of transforming sensitive cell to resistant cell. METHODS We detected the expressio...

The combination of NO-releasing nanoparticles with anticancer therapies might reverse multidrug resistance in cells.

Background: Multidrug resistance and production of extended spectrum β-lactamases (ESBLs) by enteric gram-negative rods in hospitals and community continue to be worsened. We aimed to characterize the multidrug resistance and determine the prevalence of ESBL production by clinical isolates of Enterobacteriaceae in southeast Iran. Methods: Gram-negative bacteria isolated from clinical samples of...

Acquired multidrug resistance is a major obstacle to a cure for small cell lung cancer (SCLC). Overexpression of the MDR1 gene occurs infrequently in multidrug-resistant SCLC cell lines. The multidrug resistance protein (MRP) can confer multidrug resistance, but its role in clinically acquired drug resistance is unknown. The purpose of this study was to measure expression of MRP and MDR1 mRNA i...

The increase in frequency of Salmonella enterica resistant to antibiotics in food-producing animals is of great concern to public health. Determining the rate at which different resistance phenotypes are generated and maintained in the environment is thus of great importance. The distribution and evolution of antibiotic resistance and multidrug-resistance in 362 Salmonella stains as part of a c...

background and objectives : salmonella is one of the leading causes of food-borne diseases. increasing occurrence of antimicrobial resistance, especially multidrug-resistance, in salmonella serovars is a major public health problem worldwide. this study was carried out to detect class i integrons and antibiotic resistance profiles in clinical isolates of salmonella serovars collected from seven...

Multidrug resistance in gram-negative bacteria appears to be primarily the result of the acquisition of resistance genes by horizontal transfer. To what extent horizontal transfer may be responsible for the emergence of multidrug resistance in a clinical setting, however, has rarely been investigated. Therefore, the integron contents of isolates collected during a nosocomial outbreak of genotyp...

Fifty-two canine and eighteen feline primary pulmonary carcinomas were evaluated immunohistochemically for the expression of proteins associated with multidrug resistance to anti-cancer drugs. P-glycoprotein (PGP), multidrug resistance-related protein (MRP) and lung resistance-related protein (LRP) expression were frequently observed in neoplastic cells of all carcinoma types, and metallothione...
