Seventy-two bacterial strains were isolated from twenty various sources including soil, water, rotten fruits, vegetables etc. Preliminary screening for pectinase producing bacterial strains was done by well plate method and twenty-six bacterial strains gave zones on Minimum Salt (MS) medium supplemented with 0.2% pectin. Most of the isolates belonged to plant origin, either rotten fruits or veg...

The present study aimed at to evaluate the antimicrobial activity of methanol extracts of the endemic medicinal plant, Ceropegia pusilla against five different bacterial strains namely, Shigella sonnei MTCC 2957, Klebsiella pneumoniae MTCC 109, Escherichia coli MTCC 118, Staphylococcus aureus ATCC 43300 and Bacillus sp., and four different fungal strains namely, Aspergillus sp., Mucor sp., Peni...

BACKGROUND AND OBJECTIVE The aim of our study was to characterize gizzard Lactobacillus fermentum-group strains on the basis of their phenotypic profiles regarding characteristics of lactobacilli. In addition, their in vitro potential probiotic properties were evaluated. MATERIALS AND METHODS The lactic acid bacteria were isolated and identified from gizzard contents of Algerian local poultry...

Klebsiella pneumoniae is a Gram-negative pathogen that has a large accessory genome of plasmids and chromosomal gene loci. This accessory genome divides K. pneumoniae strains into opportunistic, hypervirulent, and multidrug-resistant groups and separates K. pneumoniae from two closely related species, Klebsiella variicola and Klebsiella quasipneumoniae. Some strains of K. pneumoniae act as oppo...

in this essay, the heavy metal resistance patterns of bacterial strains isolated from industrial wastewater, domestic wastewater and various parts of the wastewater treatment system of arak city have been studied. 28 intestinal bacterial strains were screened and identified as klebsiella, escherichia coli, citrobacter and enterobacter species biochemical methods. the minimum inhibitory concentr...

An outbreak of R-factor-mediated carbenicillin resistance in Pseudomonas aeruginosa in burned patients in March 1969 was followed by a second outbreak 6 months later. No R-factor-carrying P. aeruginosa strains were detected in the intervening period but R-factor-determined lactamase was commonly encountered, particularly in Klebsiella aerogenes strains. A comparison of the molecular properties ...

Topical chemoprophylaxis of extensive burns with silver sulphadiazine cream led to a large increase in the proportion of sulphadiazine-resistant Gram-negative bacilli in a burns unit. When all sulphonamide treatment in the ward was stopped; the incidence of sulphonamide-resistant strains fell back to levels similar to those recorded when silver sulphadiazine treatment was introduced. This was a...

conclusions the prevalence of esbl-producing klebsiella strains in shahid-beheshti hospital in kashan has increased. the study concluded that there was a high prevalence of the blactx-m type gene among esbl positive isolates. patients and methods one hundred klebsiella spp. were isolated from clinical specimens of hospitalized patients at shahid-beheshti hospital from december 2012 to november ...

Klebsiella species normally produce a chromosomally encoded group 2b, or molecular class A, -lactamase. In most strains of Klebsiella pneumoniae the enzyme has an isoelectric point (pI) of 7.6, identical to that of the plasmidencoded -lactamases SHV-1 and SHV-2, and is assumed to be SHV-1. This -lactamase is transposon-encoded and it has been postulated that it might have arisen as a klebsiella...

INTRODUCTION Increase in extended-spectrum β-lactamases (ESBL) producing microbes in recent years has led to limitations of treatment options. This study aimed to assess the prevalence of ESBL producing E. coli and Klebsiella spp. at a tertiary hospital in Nepal. METHODS A total of 2209 non-repetitive mid-stream urine (MSU) samples were collected during the study period (March to September 20...
