Drug resistance (especially multiple drug resistance) in Mycobacterium tuberculosis makes global concerns in treatment and control of tuberculosis. Rapid diagnosis of drug resistant strains of the bacteria has vital importance in the prognosis of the disease. The aim of this study was to identify the mutations responsible for drug resistance in Mycobacterium tuberculosis strains derived from pa...

results the results showed that the isolated e. coli strains were sensitive to these antibiotics: erythromycin (52.94%), tetracycline (76.47%), ceftazidime (41.17%), cefixime (35.29%), penicillin (76.47%), ampicillin (58.82%) and nalidixic acid (41.17%). examination of the herbal extracts showed that the highest maximum inhibitory concentration (mic) against drug resistant e. coli was 200 ppm. ...

A cross-sectional study was conducted on street-vended food randomly from different areas of Kathmandu Valley to assess the number viable bacteria in street food, distribution bacteria, antibiotics resistance profile isolated Methicillin-resistant S. aureus (MRSA), and Vancomycin-Resistant (VRSA) valley. Altogether 339 isolates were identified one hundred eighty (180) samples. The average mean ...

from hygienic and economical point of view, drug therapy and prophylaxy in infectious diseases are of great importance. after the world war ii, a reduction in the efficacy of sulfonamide in the treatment of shigellosis was observed and later on it led to a survey on drug resistance and the way of its transmission. the aim of this survey, during which 100 cases of gram-negative bacteria were ide...

background many efforts have been made by researchers to find new antibiotics which are clinically useful against bacteria and drug resistant microorganisms. objectives we aimed to evaluate the antimicrobial effects of hydroalcoholic extracts of leaves and seeds of the portulaca oleracea plant in traditional medicine of sistan region, southeast of iran. materials and methods in this cross-secti...

Background & Aims: Imipenem is a member of Carbapenem with stability against most -lactamases .It is of particular use in the treatment of infections associated with drug resistant gram negative bacteria harboring ESBL and AmpC genes. The aim of this study was to determine the imipenem resistance in gram negative bacteria causing nosocomial infections and the presence of metallo--lactamases (MB...

Objective(s):Urinary tract infection (UTI) caused by bacteria is one of the most frequent infections in human population. Inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. However, use of probiotic bacteria has been suggested as a partial replacement. This study was aimed to assess the antagonistic effects of Lactobacillus standard strains against bacte...

Infections caused by drug-resistant microorganisms result in significant increases in mortality, morbidity, and cost related to prolonged treatments. The antibacterial activity of silver nanoparticles against some drug-resistant bacteria has been established, but further investigation is needed to determine whether these particles could be an option for the treatment and prevention of drugresis...

conclusions the result of the current study showed the growing number of nosocomial infections associated with xdr a. baumannii causing difficulties in antibiotic therapy. resistant strains increasingly cause public health problems; therefore, their early detection is essential for healthcare centers. results among the 121 isolated a. baumannii, 44% and 56% were isolated from female and male, r...

Patients may harbor both drug-susceptible and -resistant bacteria, representing heteroresistance. We studied mixtures of isoniazid-resistant and -susceptible Mycobacterium tuberculosis strains. Conventional drug susceptibility testing was the most sensitive method of detection, whereas the line probe assay and sequencing were not able to detect the clinically relevant 1% proportion of resistant...
