The resistance of microorganisms to antibiotics has become a serious issue in recent years in the therapy of bacterial infections. This problem also concerns the treatment of infections caused by Helicobacter pylori strains. The aim of this study was to evaluate the frequency of primary resistance of H. pylori strains isolated from children and adults. The subject of the research was 105 strains of...
Nickel resistant bacteria (ZB, ZC, ZD, ZL, ZK and SIX) were isolated from industrial effluents and corroded iron pieces from indigenous environment of Punjab, Pakistan. These six strains could tolerate nickel at different levels with ZB, ZC, ZD, ZL, ZK, and SIX having 233, 225, 267,233,228 and 296 mM minimum inhibitory concentration (MIC) of nickel ions, respectively. These bacteria were sensitive...
The aim of the research was the determination of resistance to fluoroquinolones (ciprofloxacin and enrofloxacin) of 387 Campylobacter sp. strains isolated from poultry between 1994-1996 (broilers, laying hens) and between 2005-2008 (broilers, laying hens, and turkeys). The resistance was determined by an agar dilution method (MIC), with accordance to Clinical and Laboratory Standards Institute recommendation...
The aim of the research was the determination of resistance of 387 Campylobacter sp. strains isolated between 1994 and 1996 (broilers, laying hens) and 2005-2008 (broilers, laying hens, turkeys) to tetracycline, erythromycin, and gentamicin. The resistance was determined with the reference to minimum inhibitory concentration on the agar plates (MIC). Limit concentration value for tetracycline and...
A total of 69 Campylobacter jejuni and 16 Campylobacter coli strains isolated from chicken, dog and pig stool samples were characterized based on their resistance to five antimicrobial agents and on plasmid pTet profiles. Antimicrobials used in this study were: amoxicillin/clavulanic acid, ciprofloxacin, erythromycin, tetracycline and trimethoprim/sulfamethoxazole. Among the isolates studied, 91.7%...
Antimicrobial susceptibility of isolated enterotoxigenic E. coli, Salmonella enterica serovar Choleraesuis, Pasteurella multocida and Streptococcus suis from pigs was tested in the Veterinary Institute of the Lithuanian Veterinary Academy. Commensal E. coli and Enterococcus faecalis were also included in the testing as commensal bacteria. Clinical and pathological material was investigated from various...
