Commercial sex workers (CSWs) serve as the most important reservoir of sexually transmitted diseases (STD), including gonorrhea. Periodic monitoring of the antimicrobial susceptibility profile of Neisseria gonorrhoeae in a high-risk population provides essential clues regarding the rapidly changing pattern of antimicrobial susceptibilities. A study concerning the prevalence of gonococcal infect...

Plasmid DNA chromatography is a powerful field in constant development and evolution. The use of this technique considered mandatory the production an efficient safe formulation to be applied for plasmid-mediated gene therapy. Concerning this, search ideal chromatographic support/ligand combination motivated scientist pursue continuous improvement on plasmid performance, looking progression lig...

background and objectives: bacteria, most prevalently the pseudomonas species possess high capacity to utilize and de- grade petroleum hydrocarbons and are classified as the hydrocarbonoclastic microorganisms. many species of the genus pseudomonas are notorious for their aerobic degradation capacity, extracellular enzyme production and are metabolically versatile organisms capable of utilizing ...

The incidence of virulence factors among 114 Enterococcus faecalis and 35 Enterococcus faecium strains from different clinical specimens were compared with those isolated from control groups. A few of the isolates expressed two or more of the following traits simultaneously: hemolysin, aggregation substance, gelatinase, DNase, hemagglutinin and antibiotic resistance. The frequencies of hemolysi...

prepulse inhibition (ppi), the objective measure of sensorimotor gating disturbance has being widely used in animal models of schizophrenia. dopaminergic direct and indirect agonists impair ppi. however, the profile of dopaminergic receptors involved in ppi impairment by dopamine agonists is not clear. by injecting shrna expressing plasmids against dopamine d2 receptor genes (drd2) in the nucle...

Forty-six Yersinia enterocolitica O:3 clinical isolates resistant to nalidixic acid were studied. The use of molecular typing techniques, other indicators of resistance patterns, the plasmid profile, and the presence of genes that encode aminoglycoside-modifying enzyme production suggested to us a clonal dissemination of the studied strains.
