“…The distribution of minimum inhibitory concentrations (MICs) for each antimicrobial agent is shown in Table 1 [7,8], no isolate of C. coli was obtained in the present study. In layer chickens, EM resistance was not found in 2002-2003 (0%, 0/24) [8] and in 2004, even though it was found in a small number of isolates (40.0%, 2/5) [7]. These results suggest that dynamics of EM resistance in porcine C. coli isolates should be noticed for a risk management of antimicrobial resistance in Campylobacter spp.…”

“…In this context, the emergence of EM resistance in Campylobacter isolates from food-producing animals poses a major problem for human medicine. In our previous study, we detected EM resistance in about half of the C. coli isolates examined but not in C. jejuni; resistance was mostly prevalent in the C. coli isolates from pigs on farms across Japan [7,8].…”

“…Antimicrobial susceptibility tests were carried out by an agar dilution method as previously described [8]. The distribution of minimum inhibitory concentrations (MICs) for each antimicrobial agent is shown in Table 1 [7,8], no isolate of C. coli was obtained in the present study.

ABSTRACT. 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.

“…Particularly, emerging antimicrobial resistance of zoonotic organisms in domestic animals becomes potential public health threats throughout the world. In the Japanese Veterinary Antimicrobial Resistance Monitoring (JVARM) system, several bacterial pathogens in diseased animals and some food-borne organisms [3,4] and commensal organisms [9] in healthy domestic animals were monitored for antimicrobial susceptibility. In the present study, we describe the antimicrobial susceptibilities of Staphylococcus and Streptococcus, targeted bacterial species for the monitoring, isolated from diseased animals.…”

ABSTRACT. A total of 88 Staphylococcus and 61 Streptococcus isolates from diseased animals throughout Japan were examined in 2000 for the minimum inhibitory concentrations of 24 different antimicrobials by the agar dilution method standardized by the Japanese Society of Chemotherapy. The resistance rates to aminobenzylpenicillin (36.4%) and benzylpenicillin (35.2%) were high in Staphylococcus isolates, and those to oxytetracycline (45.9%) and kanamycin (21.3%) were high in Streptococcus isolates. Two isolates resistant to oxacillin harbored the mecA gene. One was Staphylococcus epidermidis derived from a pig with arthritis, and the other Staphylococcus cohnii from a head of cattle with mastitis. KEY WORDS: antimicrobial susceptibility, Staphylococcus spp., Streptococcus spp.

“…A high percentage of C. coli strains resistant to erythromycin isolated from broiler chickens and eggslaying hens (35 and 50%) was registered in Japan (Ishihara et al, 2004), South Africa (Bester and Essack, 2008) and USA (Han et al, 2009). Authors in Italy reported a high level of resistance to erythromycin, up to 45%, in C. coli strains isolated from poultry faeces (Pezzotti et al, 2003).…”

The sensititivity of thermophilic Campylobacter strains isolated from caecum of broiler chickens as well as caecum and colon of pigs and human stools, were tested against erythromycin. In 16 strains isolated in broiler chickens, resistance rate was found to be 12.50%. Three of 10 strains of Campylobacter jejuni and one of 6 strains of Campylobacter coli isolated from broiler chickens were resistant to erythromycin. In 15 strains of thermophilic Campylobacters isolated from pigs, resistance rate to erythromycin was 40.00%. Resistance was exhibited more often in C. coli (50.00%) as compared to C. jejuni (20.00%). In 24 strains isolated from humans, resistance was demonstrated at the rate of 12.50%. Out of 17 strains of C. jejuni isolated from humans, resistance was exhibited in 17.65% strains. None of 7 strains of C. coli isolated from humans exhibited resistance to erythromycin. Thermophilic campylobacters, especially C. coli isolated from pigs were more resistant to erythromycin than strains isolated from humans and broiler chickens. Therefore, a great attention should be directed to the macrolides monitoring in swine farming in order to prevent resistance in animals and its subsequent spread to human.
