Objective(s): Bacteriophages are infectious replicating entities that are under consideration as antimicrobial bioagents to control bacterial infections. As an alternative or supplement to antibiotics, bacteriophages can be used to circumvent the resistance to existing antibiotics. The aim of this study was to assess the synergistic effect of a naturally isolated phage...

Salmonella isolates (n = 209) obtained from food animals and foods in Alberta during 1996 through 1999 were tested for sensitivity to 17 antimicrobials. Of the 3553 antimicrobial susceptibility tests on Salmonella isolates, 11.8% were positive for resistance. These isolates were commonly resistant to tetracycline (35.4%), streptomycin (32.5%), sulfamethoxazole (28.7%), ticarcillin (27.3%), and ...

A lysate of phage 5006M was prepared on Proteus mirabilis ~ ~ 5 0 0 6 which harboured the plasmid P-lac to which the ampicillin resistance gene of R plasmid RP4 had been transposed. This lysate transduced the ampicillin resistance marker to ~ ~ 5 0 0 6 at a frequency of 5 x 10-l~ per plaque-forming unit adsorbed. Five independently derived transductants were induced with ultraviolet light and y...

We validated a novel method for screening Escherichia coli resistance to antibiotics in environmental samples using modified Difco MI agar (Becton Dickinson) impregnated with selected antibiotics (tetracycline, ampicillin, cephalexin, and sulfamethoxazole), termed MI-R. This method combines an existing rapid assessment technique for E. coli enumeration with clinical reference data for breakpoin...

background research to understand and control the emergence and spread of antimicrobial resistance has become a public health priority. objectives this study was conducted to study epidemiology and resistant pattern of bacteria causing infection in different king khalid hospital units. patients and methods all samples were sent to the lab and routinely processed according to the standard microb...

background and objective: urinary tract infection (utis) is one of the most common diagnosed infectious diseases. in order to determine the spectrum of bacterial etiology and antibiotic resistance pattern of the uropathogens that cause community acquired uti, a retrospective study was performed in research center of reference laboratories of iran on urine samples of referred patients during a 4...

Most ampicillin-resistant Shigella are susceptible to cephalexin. Randomized treatment with cephalexin or ampicillin was given to 154 infants and children with acute diarrhea. Rectal swab cultures revealed Shigella in 42%, Salmonella in 6%, enteropathogenic Escherichia coli in 2%, and no pathogen in 50%. Cephalexin failed to eradicate Shigella after 5 days of treatment in 76% of patients as con...

background: we reviewed the monthly laboratory surveillance reports and hospital laboratory database in dhahira region, oman. methods: all patients for whom a stool sample examination request was made from 1 st january 2002 to 31 st december 2006 (5 years) were included in the study. antimicrobial resistance pattern was studied for 2 years period. the cultures were done using standard laborator...
