BACKGROUND: Salmonellosis is one of the most importantzoonotic diseases throughout the world. OBJECTIVES: Thepurpose of this study was to characterize a large collection ofSalmonella isolates from different poultry sources in Iran.METHODS: A total of 123 Salmonella isolates from differentpoultry sources were subjected to drug susceptibility test,hemolysin production, motility test, and plasmid ...

Cultures of Staphylococcus epidermidis from the eyes or nose of the same individual were compared by their antimicrobial phenotype, Staph-Ident (Analytab Products, Inc., Plainview, N.Y.) profile number, phage type, and plasmid profile to determine which parameters provide the most compelling data for their identity. None of the parameters alone provided this type of information. The most conclu...

Campylobacter pylori isolates from 37 symptomatic patients and 3 asymptomatic volunteers were examined by chromosomal DNA restriction endonuclease analysis and determination of plasmid profile. Restriction digests with HindIII, HaeIII, PvuII, and BglII produced clear and reproducible results that permitted discrimination between different strains. Only 35% of C. pylori isolates were found to ha...

conclusions based on our findings, p. aerugionsa is a major causative agent of wound infections and amikacin could be considered as a more effective antibiotic for treatment of the burned patients. background nowadays, the treatment of burned patients is difficult because of the high frequency of infection with antibiotic resistance bacteria. objectives this study was conducted to evaluate the ...

OBJECTIVE The goal of the present study was to investigate the effect of IL-12 expressed in plasmid on the Th1 cytokine profile in an experimental HPV16-positive murine tumor model and the association with the IL-12's antitumor effect. METHODS Mice were injected with BMK-16/myc cells to establish HPV16-positive tumor and then pNGVL3-mIL-12 plasmid; pcDNA3 plasmid or PBS was injected directly ...

UPEC is responsible for morethan 90% of UTI. Conventional and molecular characterizations are essential for epidemiological surveillance as well as proper management of diseases. Virulence factors, antibiotic susceptibility, RAPD pattern, plasmid profile of the E. coli isolated from UTI cases were studied using standard methods. Antibiotic susceptibility pattern of 127 uropathogenic E. coli rev...

Laboratory strains of Escherichia coli containing plasmid pBR325 (or pBR322) were coincubated with a mobilizer strain of E. coli (containing the conjugative plasmid R100-1) and a recipient strain of bacteria. Bacterial strains isolated from raw wastewater or a plasmid-free E. coli laboratory strain served as recipients. Transfer of the pBR plasmid into the recipient strain occurred during a 25-...

In this study, we used plasmid profile analysis, XbaI macrorestriction with pulsed-field gel electrophoresis (PFGE), and PCR of the ipaH gene, to study the molecular characteristics of 183 Shigella spp. isolated during May 2000 to April 2003 from rectal swabs of patients with watery and/or bloody diarrhoea in a new industrialized area of Thailand. Among the 183 isolates, 167 were S. sonnei and ...

Abstract Background The discovery of the superbug mcr-1 -positive Escherichia coli (MCRPEC) has drew greet attention. Swine-origin multi-drug resistant MCRPEC been a potential threat to public health and safety. However, there were few detailed studies have reported on swine in Guangxi, South China. Results In this study, thirty-three strains detected from 142 E. 116 samples Guangxi 2018. Which...
