background and objectives: tannins are toxic polyphenols that either bind and precipitate or condense proteins. the high tannin content of some plants is the preliminary limitation of using them as a ruminant feed. so, the aim of this study was the isolation and characterization of tannic acid degrading bacterial strains from goat feces before and after feeding on pis- tachio-soft hulls as tann...
conclusions the clinical klebsiella strains isolated from lahore region, pakistan exhibited resistance to most commonly used antibiotics, which can be a serious threat to public health. the study reported some potential actinomycetes strains, which exhibit promising activity against multidrug resistant klebsiella strains. results the isolated klebsiella strains showed resistance against most of...
Two hundred strains ofKlebsiella species isolated from clinical specimens over a four-month period were biotyped as Klebsiella aerogenes (173 strains), Klebsiella ozaenae (15 strains), Klebsiella edwardsii (5 strains), Klebsiella atlantae (2 strains) and Klebsiella oxytoca (1 strain). Klebsiella aerogenes and Klebsiella ozaenae were more resistant towards antibiotics when compared with other sp...
Background: The urinary tract infection is the secondary most common human infection. Colon bacteria, including Klebsiella pneumonia, are the main cause of urinary tract infections. The occurrence of the antibiotic resistance is a major problem in the treatment of infections. Beta- lactamases and efflux pumps constitute the major defense mechanisms of antibiotic resistance of Klebsiella pneumon...
The applicability of Enterobacter cloacae and Klebsiella typing reagents for classifying clinical strains of Enterobacter aerogenes was evaluated. Of 75 strains, none were agglutinated by E. cloacae O antisera or were sensitive to E. cloacae bacteriophages. In contrast, 70 strains reacted with Klebsiella capsular antisera. Two-thirds of the strains were lysed by Klebsiella typing phages. A set ...
Background and Objective: Klebsiella pneumoniae is known as one of the opportunistic pathogens. The prevalence of antibiotic resistance, emergence of multidrug resistant strains, and multiple virulence factors contribute to the development of various infections. In this regard, the aim of this study was to evaluate the frequency of fimH, magA, and rmpA genes among Klebsiella pneumoniae isolates...
Abstract Background and Objective: Klebsiella pneumoniae is an opportunistic nosocomial pathogen causing a variety of infections including urinary tract infections, pneumonia, septicemia, wound infections and infections in the intensive care units. Since the ESBL producing Klebsiella pneumoniae strains are increasingly causing urinary tract infections, we aim to assess antibiotic resistance pat...
INTRODUCTION Frequency of extended-spectrum beta-lactamases (ESBLs) and its variants may vary in different geographical areas, as reports indicate their spread in some certain communities. The aim of this study was to determine the frequency of ESBLs in strains of Klebsiella and E. coli, isolated from patients hospitalized in teaching hospitals of Yazd. METHODS This cross-sectional study was ...
Background and Aim: Klebsiella pneumoniae is a member of the Enterobacteriaceae family. There is a global emergence of multidrug-resistant (MDR) strains of K. pneumoniae, a Gram-negative enteric bacterium that causes nosocomial and urinary tract infections. The aims of the present study were to identify the Klebsiella pneumoniae infections in hospitalized patients, characterization of blaCTX ge...
Klebsiellae are an important cause of nosocomial infections. The two clinically relevant species, Klebsiella pneumoniae and Klebsiella oxytoca, are differentiated by the ability to produce indole from tryptophan, K. oxytoca being indole positive. We report here the detailed biochemical and molecular analysis of two isolates of Klebsiella, cultured from the same urine specimen, that differed onl...
