| The paper deals with the hygienic advantages of sanitation to treat dairy manure in full-scale biogas plants. Slurry samples were collected from two thermophilic biogas plants (55ºC) and two mesophilic biogas plants (38ºC) in Hokkaido, Japan. The detectable number of Coli-aerogenes group and Enterococcus in the slurries after anaerobic digestion could not be found in both thermophilic biogas plants. In both mesophilic biogas plants, however, the viable numbers of Coli-aerogenes group and Enterococcus were detected in the slurries even after anaerobic digestion. The mean decimation reduction time (T90) values of Coli-aerogenes group and Enterococcus in the slurries during mesophilic digestion were 13.3 d and 16.7 d, respectively. |

| Os Enterococcus são importantes agentes de infecções oportunistas em humanos e animais e estão associados à crescente ocorrência de resistência a múltiplos antimicrobianos. Considerando estes aspectos e a ampla distribuição desses microrganismos na natureza, torna-se relevante rastrear a susceptibilidade a antimicrobianos entre amostras deste gênero em diferentes reservatórios. Dessa forma, o presente trabalho foi delineado para avaliar a susceptibilidade a antimicrobianos entre amostras de Enterococcus isoladas de aves de rapina. Para tal, foi coletado material fecal, com auxílio de swabs, da cloaca de 62 aves pertencentes a 11 diferentes espécies de Falconiformes e Strigiformes. Os materiais foram coletados das aves mantidas em cativeiro, ou recém... |

| Entre los años 1996 y 2010 se estudiaron 1873 aislamientos de Enterococcus spp. pertenecientes a pacientes internados en un hospital universitario de la Ciudad Autónoma de Buenos Aires con infección intrahospitalaria. El 64,2% y el 30,4% de los aislamientos correspondieron a E. faecalis y E. faecium, respectivamente. En el periodo estudiado las infecciones por Enterococcus spp. representaron entre el 8% y el 10% del total de las infecciones nosocomiales. La prevalencia de E. faecium aumentó de un 1,5% en el año 1996 a un 4% en 2010. El primer aislamiento de enterococo resistente a vancomicina se detectó en el año 1998 y correspondió a un E. faecium y en el año 2004 se halló en E. faecalis. Actualmente más del 70% de los aislamientos de E. faecium son... |

| Este estudo objetivou avaliar o efeito de simbiótico sobre desempenho, rendimento de carcaça e qualidade da carne de aves. Dois experimentos foram realizados, com 800 aves em cada, distribuídas em quatro tratamentos: fêmeas e machos suplementados (grupos MC e FC) ou não (grupos MS e FS) com simbiótico na ração inicial. Os resultados mostraram que a suplementação de simbiótico na ração inicial aumentou significativamente o consumo médio de ração dos machos na fase final do primeiro experimento e das fêmeas na fase de crescimento do segundo experimento. Os machos não-suplementados mostraram maior consumo de ração na fase de crescimento do segundo experimento. No primeiro experimento, a suplementação de simbiótico melhorou a conversão alimentar de ambos os... |

| It was studied whether vancomycin-resistant enterococci (VRE) colonize poultry raised without receiving antimicrobial growth promoters (AGP), in non-intensive production systems. A total of 200 cloacal swabs were colleted in farms (n=40) of eight different regions of the Distrito Federal. After selective isolation, the typical enterococcal colonies were submitted to the multiplex PCR to identify enterococcal species (E. faecalis, E. faecium, E. gallinarum, and E. casseliflavus), and genes coding for high-level vancomycin resistance phenotypes. No VRE were found in the examined samples. The prevalence rates were higher for E. gallinarum (n=26; 13.0%) and E. casseliflavus (n=11; 5.5%). It was found remarkable differences in the prevalence of E. gallinarum... |

| The reduction in time required to identify vancomycin-resistant enterococci (VRE) has gained increased importance during hospital outbreaks. In the present study, we implemented a laboratory protocol to speed up the VRE screening from rectal samples. The protocol combines a medium for selective VRE isolation (VREBAC®, Probac, São Paulo) and a multiplex PCR for detection and identification of vanA and vanB resistance genes. The screening performance was analyzed in 114 specimens collected from four intensive care units. The swabs were collected at two periods: (1) during a VRE outbreak (February 2006, n=83 patients) and (2) at the post-outbreak period, after adoption of infection control measures (June 2006, n=31 patients). Forty-one/83 VRE (49.4%) and... |

| ABSTRACT This study highlights the prevalence of aminoglycoside-modifying enzyme genes and virulence determinants among clinical enterococci with high-level aminoglycoside resistance in Inner Mongolia, China. Screening for high-level aminoglycoside resistance against 117 enterococcal clinical isolates was performed using the agar-screening method. Out of the 117 enterococcal isolates, 46 were selected for further detection and determination of the distribution of aminoglycoside-modifying enzyme-encoding genes and virulence determinants using polymerase chain reaction -based methods. Enterococcus faecium and Enterococcus faecalis were identified as the species of greatest clinical importance. The aac(6')-Ie-aph(2")-Ia and ant(6')-Ia genes were found to be... |

| In the past two decades the members of the genus Enterococcus have emerged as important nosocomial pathogens worldwide. In the present study, we evaluated the antimicrobial resistance and genotypic characteristics of 203 Enterococcus spp. recovered from different clinical sources from two hospitals in Porto Alegre, Rio Grande do Sul, Brazil. The species were identified by conventional biochemical tests and by an automated system. The genetic diversity of E. faecalis presenting high-level aminoglycoside resistance (HLAR) was assessed by pulsed-field gel electrophoresis of chromosomal DNA after SmaI digestion. The E. faecalis was the most frequent specie (93.6%), followed by E. faecium (4.4%). The antimicrobial resistance profile was: 2.5% to ampicillin,... |

| Enterococci resistance to glycopeptides was evaluated em Brazilian poultry fed with feed supplemented with avoparcin as growth promoter. The susceptibility to the glycopeptides avoparcin, teicoplanin and vancomycin was determined for 217 enterococci isolated from cloacal swabs (one swab per bird) in tests and controls groups. Tests group comprised three groups (A, B and C) of Hubbard broiler-chickens 14, 21 and 35 days old, respectively. These birds were from one single farm, with a common feed source supplemented with avoparcin (10 mg/kg of feed). Controls groups (1 and 2) comprised 25 and 42 days old broilers, respectively, obtained from the Faculty of Veterinary Medicines aviary (University of São Paulo) where avoparcin was never used. No glycopeptide... |

| The objective of this paper was to assess bacteriological quality of drinking water in a peri-urban area located in the Metropolitan Region of São Paulo, Brazil. A total of 89 water samples were collected from community plastic tanks and 177 water samples from wells were collected bimonthly, from September 2007 to November 2008, for evaluating bacteriological parameters including: Escherichia coli, Enterococcus and heterotrophic plate count (HPC). Clostridium perfringens was investigated in a subsample (40 samples from community plastic tank and 40 from wells). E. coli was present in 5 (5.6%) samples from community plastic tanks (2.0 - 5.1x10(4) MPN/100mL) and in 70 (39.5%) well samples (2.0 - 8.6x10(4) MPN/100mL). Thus, these samples were not in... |
