recent technological improvements have extended the application range of dielectric permittivity biomass measurements to on-line monitoring of physiological changes during bacterial fermentations. in an industrial fermentation of bacillus thuringiensis, it is important to verify the intactness of bacterial plasmid content in all steps of culture. changes in certain plasmid resident properties o...

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...

Methicillin-resistant Staphylococcus aureus (MRSA) has been listed by the World Health Organization as a priority antibiotic-resistant nosocomial pathogen in urgent need of new antimicrobials [1]. Plasmids are key factor pathology and epidemiology MRSA isolates play important roles their evolution. In our on-going efforts to better understand genetic background molecular from Terengganu, Malays...

Mutations in the gene encoding topoisomerase I of Escherichia coli were tested for their effect on plasmid recombination. Recombination was decreased 1,000-fold at 30 and 37 degrees C and occurred at approximately wild-type frequencies at 42 degrees C. The suppression of topA mutations at 42 degrees C did not appear to be a result of increased topoisomerase I activity at 42 degrees C.

Here we report the results of second interim analysis a randomized prospective multi-center clinical study aimed to evaluate safety and efficacy p62/SQTM1-encoding plasmid applied as an adjuvant chemotherapy in patients with advanced platinum-resistant ovarian cancer. P62 encoding acts classic anti-cancer DNA vaccine it also lowers chronic inflammation thus rendering tumor cells more susceptibl...

Investigation of the Frequency Plasmid-Dependent Quinolone Resistance Genes in Klebsiella Pneumoniae, Pseudomonas Aeruginosa and Escherichia Coli Isolated from Surgical Site Infections

from plasmid pSCFS1, was found downstream of the cfr gene in pMSA16. The 2848 bp fragment containing the cfr gene and its downstream pre/mob gene showed 100% nucleotide sequence identity to the corresponding parts in plasmids pBS-01 and pBS-02. In conclusion, this is the first report describing the presence of the cfr gene in a bovine MRSA ST9 strain. Moreover, this is also the first report of ...
