Antimicrobial resistance of Salmonella isolates from swine.
We examined the antimicrobial resistance of 1,257 isolates of 30 serovars of Salmonella enterica subsp. enterica isolated from swine. Serovars Typhimurium and Typhimurium var. Copenhagen were widespread and were frequently multidrug resistant, with distinct resistance to ampicillin, kanamycin, streptomycin, sulfamethoxazole, and tetracycline and to ampicillin, chloramphenicol, streptomycin, sul...
متن کاملCharacterization of multiple-antimicrobial-resistant Escherichia coli isolates from diseased chickens and swine in China.
Escherichia coli isolates from diseased piglets (n = 89) and chickens (n = 71) in China were characterized for O serogroups, virulence genes, antimicrobial susceptibility, class 1 integrons, and mechanisms of fluoroquinolone resistance. O78 was the most common serogroup identified (63%) among the chicken E. coli isolates. Most isolates were PCR positive for the increased serum survival gene (is...
متن کاملAntimicrobial drug resistance of Salmonella and Escherichia coli isolates from cattle feces, hides, and carcasses.
To determine patterns of cross-contamination and antibiotic susceptibility of microorganisms commonly associated with cattle, 60 cattle shipped to a commercial abattoir (20 in each of three separate trial periods) were followed through processing. Samples for bacterial isolation were collected from the feces and hides immediately before shipping, from the hides at the abattoir after exsanguinat...
متن کاملAntimicrobial drug resistance of fecal Escherichia coli and Salmonella spp. isolates from United States dairy cows.
Antimicrobial resistance is a growing concern for public and animal health. Threats to public health could come from the transfer of pathogens from animals to people via indirect contact such as through food or by direct contact with animals. In addition, concern has been raised for the potential transfer of resistance determinants from animals to humans through commensal bacterial flora such a...
متن کامل[Antimicrobial susceptibility of Escherichia coli isolates from river water ecosystems].
INTRODUCTION Antimicrobial resistance is one of the biggest problems facing global public health. The emergence of resistant clinical and environmental strains worsens the situation. Among the microorganisms with antimicrobial resistance, Escherichia coil species stands out due to its dual role as fecal contamination indicator and pathogen. OBJECTIVES To isolate and identify Escherichia coil ...
