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...

34 Present study was carried out to determine the difference between the wild type rhizobial strains and plasmid cured strains for some important characteristics such as antibiotic resistance. The rhizobial strains were isolated from locally produced legumes of different varieties such as Pisum sativum, Sesbania aculeata, Vigna mungo, Phaseolus vulgaris, Lens culinaris and Arachis hypogea.They ...

Background: Urinary tract Infections caused by multidrug resistant uropathogens have become a significant global public health problem with Nigeria being no exception.
 Objective: This study is aimed at profiling and curing the plasmids of selected isolated from patients urinary infection in tertiary hospital Calabar, Nigeria.
 Methodology: Isolates were obtained urine samples using s...

Plasmid-containing bacteria often cause serious therapeutic failure during the treatment of infectious diseases. The selection of resistant-mutant strains and the transfer of mobile genetic determinants (such as plasmids and transposons) of resistance promote increased antibiotic resistance. In the last 30 years the antiplasmid effect of acridine dyes, ethidium bromide, sodium dodecyl sulphate ...

Objective: The aim of the present study is to evaluate the plasmid profile and curing in extended spectrum beta-lactamases (ESBL) producers and know the association of biofilm formation among ESBLs. Methods: Standard disk diffusion method (Kirby Bauer’s method) was performed to know the sensitivity and resistance patterns for commonly used antibiotics and clinical laboratory standard institute ...

Plasmids are extrachromosomal pieces of double-stranded circular DNA which have the capability to replicate independently of the.Growth dynamics of multiple component communities of bacteria. Thus curing by acridines normally involves loss of the whole plasmid.Plasmids are extrachromasomally replicating molecules of DNA present in bacteria.Plasmid curing is a process of completely removing plas...

Staphylococcus aureus and Pseudomonas aeruginosa strains were isolated from eye swab samples randomly obtained from 100 seropositive HIV/AIDS patients who reported to various anti-retroviral treatment clinics at the University of Benin Teaching Hospital and Central Hospital both based in Benin City, Nigeria. Invitro antibiotic sensitivity patterns of strains before curing were determined by the...

Earlier report has shown the Lactobacilli isolates from some traditional fermented foods, LABB (appam batter) and LABP (vegetable pickle) to produce bacteriocins, inhibitory to a variety of spoilage and pathogenic organisms. In the present study, the plasmid profile, their curing and transformation experiments were carried out to deduce if the bacteriocins are plasmid mediated. Both the strains...
