Megjegyzések:AIMS:We compared the prevalence of extended-spectrum beta-lactamase (ESBL) producers in the faecal samples of 1,109 healthy individuals screened for employment purposes and in 531 asymptomatic individuals applying for long-term care (LTC).METHODS:Eosin-methylene blue agar plates supplemented with 2 mg/l cefotaxime were used to determine which individuals were ESBL producers. ESBL phenotype was confirmed by double-disk synergy test and ESBL genes were identified by sequencing. ESBL producers were characterized by co-resistance and integron carriage.RESULTS:ESBL producers were more frequent in the LTC applicants than in the employment screening individuals (7.2 vs. 2.0%; p < 0.0001), with 43 Escherichia coli, 18 Klebsiella pneumoniae, 1 Klebsiella oxytoca and 1 Proteus mirabilis being found. In the employment screening individuals, only E. coli was found. Most ESBL genes (79.4%, 50/63) were blaCTX-M type; blaCTX-M-15 was more frequent in the LTC applicants (p < 0.001). Regarding ESBL genes and integron diversity, E. coli isolates from the LTC applicants were more similar to K. pneumoniae than to E. coli from the employment screening individuals.CONCLUSION:These differences in the characteristics of ESBL producers may represent different sources of colonization. Most LTC applicants harboured K. pneumoniae or E. coli that were probably hospital-acquired whereas the E. coli isolates of many healthy individuals showed similarities to environmental E. coli.

Cím:Asymptomatic faecal carriage of ESBL producing Enterobacteriaceae in Hungarian healthy individuals and in long-term care applicants : a shift towards CTX-M producers in the community / Fatemeh Ebrahimi, Julianna Mózes, Júlia Mészáros, Ágnes Juhász, László Majoros, Krisztina Szarka, Gábor Kardos

Megjegyzések:Background: Faecal carriage of extended-spectrum beta- lactamase (ESBL) producing Enterobacteriaceae28 in healthy individuals was examined and compared to previous results obtained in such individuals a few29 years earlier.30 Methods: Faecal samples from 779 individuals screened for employment purposes and from 22531 applicants to long-term care (LTC) were screened between November 2013 and May 2014.32 Results: The overall rate of fecal carriage was 3.0% (30/1004). The carriage rate was significantly higher33 in applicants for LTC (5.3% vs. 2.3%; p=0.019). All isolates carried CTX-M ESBLs, with an34 overwhelming dominance of blaCTX-M-15 (84.4%) in both groups and in both E. coli and Klebsiella35 pneumoniae.36 Conclusions: The prevalences were comparable to those in the earlier study, but a marked decrease of the37 diversity of ESBL genes in E. coli from the employment screening group was found, suggesting that the38 ESBL-producing isolates originating from diverse sources are being replaced by highly successful blaCTX39M-15 producing strains.

Cím:Prevalence and characterization of Salmonella infantis isolates originating from different points of the broiler chicken-human food chain in Hungary / Nógrády Noémi, Kardos Gábor, Bistyák Andrea, Turcsányi Ibolya, Mészáros Júlia, Galántai Zsuzsanna, Juhász Ágnes, Samu Péterné, Kaszanyitzky J.

Megjegyzések:During the 10-month study period Salmonella contamination of broiler houses and the flocks reared in three farms (A, B and C), the slaughter houses where the flocks were slaughtered, as well as the carcass and retail raw meat products originating from them was investigated. In the broiler farm A five consecutive flocks, in the B and C farms one flock was sampled. Environmental samples were taken prior to the introductions. Environmental, drinking water, feed and faecal samples were collected regularly using standard methods. Before and during processing of the flocks, environmental and carcass samples were taken at the abattoirs. Salmonella contamination of the carcass, retail meat, as well as stool samples of farm and abattoir workers and from human illnesses registered in the same period and region were also examined. Isolation, sero-, phage- and antibiotic resistance typing, class 1 integron and plasmid profiling of the strains were performed; their genetic relationship was assessed by PFGE. Although the broiler house and the faecal samples of the 5 flocks of the farm A were negative for Salmonella, S. infantis was isolated from 20?100% of the abattoir carcass samples. The retail raw meat samples were 0?100% S. infantis positive. The environmental samples of farm B were Salmonella negative, but the examined flock was contaminated: S. infantis was identified from 43% of the faecal samples. This serotype was identified in 100% of the carcass and retail raw meat samples. From environmental samples taken before the arrival of the 1-day-old chicks in the broiler house C, S. infantis was cultured. S. infantis prevalence in the faecal samples was 35% and all the carcass and retail raw meat samples were S. infantis contaminated. Altogether 164 S. infantis strains were isolated out of which 145 were further characterized. The vast majority (142/145) of the strains belonged to phage types 217 and 213. All but one were characterized by the nalidixic acid-streptomycin-sulphonamide-tetracycline resistances, had an 885 bp class 1 integron and a large plasmid of > 168 kb in size. The strains showed ? 88.7% genetic similarity. The results obtained shows that the same multi-drug resistant S. infantis clone was spread from the examined broiler farms contaminating the slaughter and the retail meat and appeared in the human illnesses of the examined region that was earlier detected as the dominant clone characteristic of the broiler and human population of the whole country.
