Drug-resistant Mycobacterium tuberculosis is challenging elimination of tuberculosis (TB). We evaluated risk factors for TB and levels of second-line drug resistance in M. tuberculosis in patients in Europe with multidrug-resistant (MDR) TB. A total of 380 patients with MDR TB and 376 patients with non-MDR TB were enrolled at 23 centers in 16 countries in Europe during 2010-2011. A total of 52....
Background: Enterococci faecalis are predominating species of Enterococci causing nosocomial infections. Acquisition of resistance to antibacterial agents, and ability to transfer the resistant genes made them clinically important. This study was performed to determine the frequency of isolation of different species of Enterococci, and the antibacterial resistance pattern of the isolated specie...
Executive summary South Africa is one of the 22 highest tuberculosis (TB) burdened countries globally and the occurrence of laboratory-confirmed multi drug resistant TB (MDR–TB) and extensively drug resistant TB (XDR-TB) has long been recognized in South Africa. A drug resistance survey (2012-2014) to quantify and delineate the extent of drug resistance in new and retreatment TB patients nation...
background: this study was done to detect multidrug resistant (mdr) and extremely drug resistant (xdr) of pseudomonas aeruginosa among strains isolated from patients in tehran, iran, due to importance of these phenotypes in treatment of human infections. methods: eighty eightp. aeruginosa were isolated from patients in tehran, iran, and identified by routine methods and pcr for oprl gene. their...
BACKGROUND Drug resistance has been a cause of concern for tuberculosis (TB) control in both developed and developing countries. Careful monitoring of the patterns and trends of drug resistance should remain a priority. METHODS Strains were collected from 1824 diagnosed sputum smear positive pulmonary TB patients in Jiangsu province of China and then tested for drug susceptibility against rif...
Drug-resistant tuberculosis is a public health concern. TB that drug-resistant to rifampin and isoniazid known as MDR-TB, whereas XDR-TB MDR-TB also resistant second-line medicines, such fluoroquinolones (levofloxacin, ofloxacin, moxifloxacin). rifampin-resistant (RR-TB), of which 78 percent had multidrug-resistant (MDR-TB) (MDR-TB). Fluoroquinolones are class broad-spectrum antimicrobials have...
Multidrug resistance (MDR) of tumor cells is a serious obstacle encountered in cancer treatment. In the current study a multiple drug‑resistant HepG2/adriamycin (HepG2/ADR) cell line was established and its MDR was characterized. Icaritin, an active ingredient isolated from the medical plant Herba Epimedium, was observed to reverse MDR in the present model. Icaritin significantly increased the ...
BACKGROUND AND OBJECTIVES Multidrug resistant (MDR) bacteria are a growing threat to global health. Studies focusing on single antibiotics have shown that drug resistance is often associated with a fitness cost in the absence of drug. However, little is known about the fitness cost associated with resistance to multiple antibiotics. METHODOLOGY We used Mycobacterium smegmatis as a model for h...
The present cross-sectional study was conducted for the first time from the Udupi district of coastal Karnataka to know the prevalence of drug resistance and comparative analysis of MDR and non-MDR cases of pulmonary tuberculosis. Details of 862 smear positive cases of pulmonary tuberculosis with age ⩾15 years from 12 designated microscopy centres of the Udupi district were studied. Initially 2...
Multidrug resistance (MDR) is a serious obstacle encountered in cancer treatment. In this study, we established an in vitro multiple drug resistant HepG2 cell line (HepG2/ADM), and characterized its MDR. This model was used to screen potential candidate chemosensitisers from over 200 purified naturally occurring compounds extracted from plants and animals. Cantharidin was found to have a signif...
