ABSTRACT Increasing antimicrobial resistance in
Salmonella species has been a serious problem for
public health worldwide. This study examines
Salmonella spp. recovered from
foods and clinical samples on
serotype, antimicrobial resistance and PFGE
genotypes. It identified 91 salmonellae,
belonging to 31 different
serotypes, from 36 isolates from
food and 55 clinical samples.
Salmonella Infantis (16.5%) and
Salmonella Enteritidis (13.7%) are the most common among
food isolates, whereas
Salmonella Enteritidis (29.0%) and
Salmonella Typhimurium (16.0%) mainly causes
human salmonellosis. Antimicrobial susceptibility data showed that 63.0% of the isolates were fully susceptible to 12
antibiotics tested.
Nalidixic acid showed high resistance rates, 32.7% and 25.0% of the clinical isolates and
food, respectively. Three main PFGE types A (
Salmonella Enteritidis), B (
Salmonella Infantis) and C (
Salmonella Schwarzengrund) comprised isolates recovered from
foods and clinical samples. Our results indicate that the clonal groups were both causing
diseases and
food contamination, emphasizing the need to maintain a system of
surveillance for
foodborne disease.
