The Bacteroides fragilis group consists of species of obligate anaerobic bacteria that inhabit the human gut. They are among the leading pathogens isolated in the setting of intra-abdominal infections. B. fragilis strains, especially in the United States, are virtually always susceptible to metronidazole, carbapenems, and beta-lactam antibiotics. Although isolated cases of resistance to single ...

Microbial resistance to antibiotics has been emerging in environmental isolates. This study was carried out from October 2008 to January 2009 to describe the antibiotic susceptibility pattern of the bacteria isolated from sewage sludge, biowaste and bioslurry samples. A total of 49 identified isolates were taken for antibiotic susceptibility test. Amikacin and Gentamicin were the effective anti...

Introduction: The incidence of multidrug resistant tuberculosis is increasing in developing countries. Aminoglycosides are an integral part of second-line drugs, however ototoxicity is a major limitation for their use. This study aims to determine the extent of hearing loss in patients taking one of the commonly prescribed drugs for Multidrug resistant tuberculosis (MDR-TB), Kanamycin, at a Gov...

Background: Multidrug-Resistant Tuberculosis (MDR-TB) has a more rapid course with poor treatment outcomes. Its requires complex multiple 2nd line drug regimens which are longer, expensive and toxic Objectives: to identify factors associated multidrug-resistant tuberculosis in order high risk population who would develop MDR-TB suggest possible measures be taken reduce incidences this region. M...

The emergence and spread of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) has raised public health concern about global control of TB. To estimate the transmission dynamics of MDR and XDR TB, we conducted a DNA fingerprinting analysis of 55 MDR/XDR Mycobacterium tuberculosis strains isolated from TB patients throughout Japan in 2002. Twenty-one (38%) of the st...

OBJECTIVE To determine the prevalence of extended spectrum beta-lactamase (ESBL) among multidrug resistant isolates of enterobacteriaceae and non-fermenting gram-negative bacilli. METHODS This study was carried out at the Almana General Hospital, Eastern Province, Kingdom of Saudi Arabia, during the period March 2002 through to June 2003. Multidrug resistant gram-negative isolates from patien...

Multidrug-resistant strain of Mycobacterium tuberculosis (MDR-Tb) and Multidrug-sensitive Mycobacterium tuberculosis (MDS-Tb) isolated from humans were injected subcutaneously into the guinea pigs. One set of infected lungs of animals was fixed in 10% formalin pH7.2, while the other set was treated with 75% ethanol 2 hours prior to fixation in 10% formalin. After six months of fixation, MDS-Tb ...

The goal of this study was to evaluate the prevalence of first-line anti-tuberculosis drug resistance and risk factors associated with multidrug-resistant tuberculosis (MDR TB) among young soldiers in the Korean military, which has a strict tuberculosis control program. All patients with culture-confirmed pulmonary tuberculosis during their service at the Armed Forces Capital Hospital from Janu...

Three independent variants (G2, G4, G5), resistant to methylglyoxal bis(guanylhydrazone), an anticancer drug, have been isolated by single step selection from an adenovirus-transformed rat brain cell line (1). These variants display selective cross-resistance to several natural product drugs of dissimilar structure and action. Multidrug resistance has recently been shown to be caused by overexp...

Multidrug-resistant (MDR) Salmonella enterica subsp. enterica serotype Newport has been a long-standing public health concern in the United States. We present the complete sequences of six IncA/C plasmids from animal-derived MDR S. Newport ranging from 80.1 to 158.5 kb. They shared a genetic backbone with S. Newport IncA/C plasmids pSN254 and pAM04528.
