چکیده

We investigated the susceptibilities against 7 antimicrobial agents in Campylobacter jejuni and C. coli isolates from food-producing animals in 2004. In comparison with the results of past surveillance, no significant difference was observed in resistance rates against all of the antimicrobials tested in Campylobacter isolates. However, slight increase of erythromycin (EM) resistance was found in C. coli isolates from pigs. We examined the mutation of the 23S rRNA gene and their susceptibilities against azithromycin, tylosin, and lincomycin in 44 EM-resistant isolates and 28 susceptible isolates of porcine origin. All the EM-resistant isolates contained A2075G in the 23S rRNA gene and showed cross-resistance to azithromycin, tylosin, and lyncomycin.

Association of antimicrobial resistance in Campylobacter isolated from food-producing animals with antimicrobial use on farms.

On 1,374 food-producing animal farms in 2001-2004, we investigated the influence of antimicrobial usage within 6 months before a survey conducted on antimicrobial resistance in Campylobacter. Tetracyclines and fluoroquinolones were used for therapeutic purposes on 107 and 21 farms, respectively. Oxytetracycline-resistant C. jejuni and C. coli were found in 57.1% (8/14) and 92.5% (37/40) of the ...

Development of macrolide-resistant Campylobacter in broilers administered subtherapeutic or therapeutic concentrations of tylosin.

The use of antimicrobials in food animal production, particularly those commonly used to treat infections in humans, has become a source of debate in recent years. However, limited data are available regarding the development of resistance following the subtherapeutic or therapeutic administration of antimicrobials in animal production. The objective of this study was to evaluate the effect of ...

Quinolone and macrolide resistance in Campylobacter jejuni and C. coli: resistance mechanisms and trends in human isolates.

The incidence of human Campylobacter jejuni and C. coli infections has increased markedly in many parts of the world in the last decade as has the number of quinolone-resistant and, to a lesser extent, macrolide-resistant Campylobacter strains causing infections. We review macrolide and quinolone resistance in Campylobacter and track resistance trends in human clinical isolates in relation to u...

Macrolide resistance mechanisms and virulence factors in erythromycin-resistant Campylobacter species isolated from chicken and swine feces and carcasses

Resistance to antimicrobials was measured in 73 isolates of Campylobacter jejuni (C. jejuni) and 121 isolates of Campylobacter coli (C. coli) from chicken and swine feces and carcasses in Korea. Both bacterial species showed the highest resistance to (fluoro) quinolones (ciprofloxacin and nalidixic acid) out of the nine antimicrobials tested. Erythromycin resistance was much higher in C. coli (...

Background: Campylobacter genus is considered some of the most important agents of bacterial gastroenteritis worldwide. Campylobacter coli (C. coli) is accounted to at least 25% of all Campylobacter related diarrheal diseases moreover, C. coli infections can result in severe complications, such as bacteremia, sepsis, meningitis and spontaneous abortion. Finally, there is evidence that the frequ...
