“…Enterococci, which express the erm(B) gene, often exhibit resistance to tetracycline in addition to resistance to MLS B . Cauwerts et al (2007) observed that in 89% of erm(B)-positive enterococci, tet genes were also present. Therefore, the frequent use of tetracyclines in poultry may co-select for resistance to MLS B antibiotics, which may be important as an alternative therapy for enterococcal infections in humans.…”

The aim of this study was to evaluate the frequency of occurrence of bacteria of the genus Enterococcus in poultry, to identify them by means of matrixassisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS), and to analyse the antimicrobial susceptibility of the isolated strains to the drugs most frequently used in poultry. The material for the bacteriological tests was obtained mainly from the heart (97%) of the birds investigated. Of a total of 2,970 samples tested, 911 (30.7%) tested positive for Enterococcus spp. Enterococci were detected in broilers (88.1%), laying hens (5.3%), turkeys (3.9%), breeding hens (2.2%), and geese (0.4%). The most commonly identified species were Enterococcus (E.) faecalis (74.7%), E. faecium (10.1%), E. gallinarum (5.5%), E. hirae (4.6%), and E. cecorum (4.1%). The most frequent resistance properties were resistance to sulphamethoxazole/trimethoprim (88%), tylosin (71.4%), enrofloxacin (69.4%), doxycycline (67.3%), and lincomycin/spectinomycin (56.1%). Only one vancomycin-resistant Enterococcus, E. cecorum from a broiler, was found.

“…Differences in the occurrence of macrolide resistance in enterococcal isolates from poultry, calves and pigs have been considered to reflect the different levels and patterns of usage of antimicrobials in those different species. This also probably accounts for the widespread occurrence of tetracycline resistance in Gallus gallus and pigs, because these species have frequently received treatment with this antimicrobial (van den Bogaard et al, 2000;Cauwerts et al, 2007).…”

The antimicrobial resistance data on zoonotic and indicator bacteria in 2010, submitted by 26 European Union Member States, were jointly analysed by the European Food Safety Authority and the European Centre for Disease Prevention and Control. Data covered resistance in zoonotic Salmonella and Campylobacter from humans, food and animals, and in indicator Escherichia coli and enterococci from animals and food. Some data on meticillin-resistant Staphylococcus aureus in animals and food were also included. In isolates from humans, resistance was mainly interpreted using clinical breakpoints, whereas in animal and food isolates, microbiological resistance was defined using epidemiological cut-off values. No major changes in resistance in monitored bacteria were observed compared with previous years. Resistance was commonly found in isolates from humans, animals and food, although disparities in resistance were frequently observed between Member States. High resistance levels were recorded to ampicillin, tetracyclines and sulfonamides in Salmonella isolates from humans, whereas resistance to third-generation cephalosporins and fluoroquinolones remained low. In Salmonella and indicator E. coli isolates from fowl, pigs, cattle and meat thereof, resistance to tetracyclines, ampicillin and sulfonamides was also commonly detected, whereas resistance to third-generation cephalosporins was low. Moderate to high levels of ciprofloxacin (a fluoroquinolone) resistance were observed in Salmonella isolates from turkeys, fowl and broiler meat. In Campylobacter isolates from human cases, resistance to ampicillin, ciprofloxacin, nalidixic acid and tetracyclines was high, while resistance to erythromycin was recorded at low to moderate levels. High resistance to ciprofloxacin, nalidixic acid and tetracyclines was also observed in Campylobacter isolates from fowl, broiler meat, pigs and cattle, whereas much lower levels were observed for erythromycin and gentamicin. Among the indicator enterococci isolates from animals and food, resistance to tetracyclines and erythromycin was commonly detected. Meticillin-resistant Staphylococcus aureus was detected in some animal species and food of animal origin. mission is to identify, assess and communicate current and emerging threats to human health posed by infectious diseases. In order to achieve this mission, ECDC works in partnership with national public health bodies across Europe to strengthen and develop EU-wide disease surveillance and early warning systems. By working with experts throughout Europe, ECDC pools Europe's knowledge in health so as to develop authoritative scientific opinions about the risks posed by current and emerging infectious diseases.

Infection can be acquired directly from animals, or through the ingestion of contaminated foodstuffs or other indirect contact. The severity of these infections in humans can vary from mild and asymptomatic to serio...

The results might suggest problems for public health due the high resistance, since these microorganisms have ability to transmit genes for antimicrobial resistance to others in the intestinal tract of humans and animals. Thus, the use of these drugs for clinical treatment could be hindered. (B), vanC-1, aph(3')-llla, ant(6)-la, vanB, vanA, aac(6')-le-aph(2'')-la, erm(A) e tet(M) -este último mais frequente. Estes resultados sugerem sérios problemas para a Saúde Pública, uma vez que esses microrganismos podem possuir a capacidade de transmitir genes de resistência antimicrobiana para outros microrganismos presentes na microbiota intestinal de humanos e animais, podendo inviabilizar o uso destas drogas para tratamentos clínicos.
