Antibiotic Resistance And Plasmid Dna Contents Of Streptococcus Thermophilus Strains Isolated From Turkish Yogurts, Belma Aslim, Yavuz Beyatli
Turkish Journal of Veterinary & Animal Sciences
Thirty-four Streptococcus thermophilus strains were isolated from yogurt samples obtained from various villages in different regions of Turkey. These strains were examined for their antibiotic resistance patterns and plasmid carriage. The susceptibility of the isolates to 8 antibiotics (vancomycin, tetracycline, chloramphenicol, erythromycin, cephalothin, ampicillin-sulbactam, gentamicin and penicillin G) was determined by the disk diffusion method. Most strains of S. thermophilus were resistant to gentamicin (79%) and penicillin G (64%) and susceptible to chloramphenicol (94%) and tetracycline (88%). In plasmid DNA analyses, it was determined that 7 strains did not contain any plasmid DNA, while other strains included plasmid DNA ranging …

The aim of this study was to examine the relationship between antibiotic resistance patterns among Salmonella enterica subsp. enterica Serovar Enteritidis isolates (Salmonella Enteritidis) of human and poultry origin. Antibiotic resistance of 97 Salmonella Enteritidis isolates from 25 chicken meat, 25 chicken intestine and 47 human fecal samples was examined using the National Committee for Clinical Laboratory Standards (NCCLS, 1997) disk diffusion method. Resistance patterns of the isolates were as follows: Of the 25 chicken meat isolates 4 were resistant to some antibiotics. Two isolates (CM15 and CM22) were resistant to ampicillin (AMP), cefuroxime sodium (CXM), ceftriaxone (CRO), trimethoprim-sulphamethazole (SXT) …
