چکیده

Raw and treated sewage samples were examined for antibiotic-resistant, lactose-fermenting bacteria. Approximately 1% of the total lactose-fermenting bacteria were multiply resistant. Of these organisms, 50% were capable of transferring all or part of their resistance to a drug-sensitive recipient. Only 43% of those isolated on media containing a single antibiotic were capable of resistance transfer, whereas 57% of those recovered on multiple antibiotic plates transferred resistance. R factors conferring resistance to chloramphenicol, streptomycin, and tetracycline; streptomycin and tetracycline; and ampicillin, streptomycin, and tetracycline accounted for 22, 19, and 15%, respectively, of those identified. The data indicate a significant level of infectious drug resistance among the intestinal bacteria of the urban population.

Effect of antibiotic treatment on the incidence of infectious drug resistance among intestinal lactose-fermenting bacteria isolated from burn patients.

Antibiotic-resistant lactose-fermenting bacteria were recovered from the feces of 20 of 25 burn patients studied. Of the Escherichia coli isolated from patients receiving antibiotic treatment, 81.5% were shown to be infectiously resistant; only 32% of the E. coli recovered from patients not receiving antibiotics were shown to be harboring R factors. Three resistance patterns, ampicillin-chloram...

Antibiotic Resistance, Plasmid and RAPD Profiles of Multidrug-resistant Coliform Bacteria Isolated from Sewage Samples of Ghaziabad City, India

The aim of the present work is to study the antibiotic resistance, plasmid and RAPD profiles of the multidrug resistant (MDR) Coliform bacteria isolated from raw and treated sewage of Ghaziabad city, India. The MDR bacterial population in the raw and treated sewage constituted 7.5% and 19.1% of the total Coliform bacteria respectively. Five MDR Coliform bacteria (2 from raw and 3 from treated s...

جداسازی و تعیین اختصاصیت باکتریوفاژ بومی اشریشیاکلی از فاضلاب خام

Introduction: Bacteriophages are viruses that infect and destroy prokaryote cells, specifically the bacteria. They act too selective, so as each bacteriophage affects only on specific type of bacteria. Due to their specific features, bacteriophages can be used as an appropriate substitute for antibiotics in infectious diseases treatment. Therefore, this study aimed to isolate E. coli-specific b...

Prevalence and In Vitro Antimicrobial Susceptibility Pattern of Non-Lactose Fermenting Gram Negative Bacteria Isolated in a Tertiary Care Hospital in Kathmandu, Nepal

Background: Non-lactose fermenting gram negative bacteria are emerging as important human pathogens. This group of bacteria was earlier considered to be colonizers but are now frequently isolated from different clinical specimens and are responsible for a wide range of human infections especially in immune compromised hosts. The main purpose of our study was to determine the prevalence and role...

Molecular Identification of ESBLs Genes (blaTEM, blaSHV and blaCTX) among Non-fermenting Gram-negative Bacteria Isolated from Hospitalized Patients in Mazandaran Province, Iran

Background and purpose: Production of beta-lactamase enzymes by bacteria, especially Extended-spectrum β-lactamases (ESBLs) is one of the major problems worldwide. ESBLs are mostly located on bacterial plasmids and it is recognized that SHV, TEM, and CTX-M are prevailing among them. The aim of this study was to determine the ability to produce ESBLs genes based on molecular method among non-fer...
