Characterization of CMY-2-type betalactamase-producing Escherichia coli isolated from chicken carcasses and human infection in a city of South Brazil.

Food-producing animals, mainly poultry, have been associated with the maintenance and dissemination of antibiotic-resistant bacteria, such as plasmid-mediated AmpC (pAmpC)-producing Enterobacteriaceae, to humans, thus impacting food safety. Many studies have shown that Escherichia coli strains isolated from poultry and humans infections share identical cephalosporin resistance, suggesting that transmission of resistance from poultry meat to humans may occur. The aim of this study was to characterize pAmpC-producing E. coli strains isolated from chicken carcasses and human infection in a restrict area and to determine their antimicrobial resistance profiles, and molecular type by multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE).ResultsA total of 14 pAmpC-producing E. coli strains were isolated, including eight strains from chicken carcasses and six strains from human infections (from urine, tissue and secretion). The bla(CMY-2) gene was identified in all pAmpC-producing E. coli strains by polymerase chain reaction (PCR) and DNA sequencing. High percentages of strains resistant to tetracycline, nalidixic acid and sulfamethoxazole-trimethoprim (78-92%) were detected, all of which were considered multidrug-resistant. Among the non-beta-lactam resistance genes, the majority of the strains showed tetA, tetB, sulI and sulII. No strain was considered an extended-spectrum beta-lactamases (ESBL) producer, and the bla(TEM-1) gene was found in 2 strains isolated from human infection. Six strains from chicken carcasses and four strains from humans infections were linked to an ISEcp1-like element. Through MLST, 11 sequence types were found. Three strains isolated from human infection and one strain isolated from chicken carcasses belonged to the same sequence type (ST354). However, considerable heterogeneity between the strains from chicken carcasses and humans was confirmed by PFGE analysis.ConclusionThis study showed the prevalence of E. coli strains producing bla(CMY-2) linked to ISEcp1 that were present in both chickens and humans in a restricted area. Our results also suggest the presence of a highly diverse strains that harbor pAmpC, indicating no clonal dissemination. Therefore, continuous monitoring and comparative analyses of resistant bacteria from humans and food-producing animals are needed19COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO ARAUCÁRIA DE APOIO AO DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO DO ESTADO DO PARANÁ - FASem informação09/2016-1074

Efeito do gengibre no poder anaeróbico de membros inferiores de ginastas da seleção brasileira

Introduction: Aerobic gymnastics is a sport that has consistently grown over the previous decades, and its practice demands its athletes to perform complex and high-intensity movements. Objective: The study was to analyze whether ginger supplementation had an ergogenic effect on the anaerobic power of limbs (PAMI) in aerobic gymnastic athletes. Methods: A randomized double-blind placebo-controlled trial was conducted with nine athletes (23.11 + 4.14 years, 1.63 + 0.09 m, 60.51 + 7.38 kg) from the Brazilian National Team of Aerobic Gymnastics. After ingesting 400 mg of Zingiber officinale or placebo for seven days, the subjects underwent an anaerobic power test (RAST). Peak Velocity and Peak power (m/s and W), average and minimum power (W), and fatigue index (W/s and %) data were obtained from the RAST. Results: After verifying the no normality of the sample, the Mann-Whitney was applied, but no significant differences were found in the peak velocity of the ginger supplementation (6.28 ± 0.41 m/s; 445.28 ± 117.15 W) compared to placebo (6.22 ± 0.45 m/s; 425.95 ± 130.39 W). Conclusions: It is concluded that ingesting 400 mg of Z. officinale does not have an ergogenic effect on the anaerobic power of the lower limbs of aerobic gymnastic athletes.Introdução: a ginástica aeróbica é um esporte que tem crescido consistentemente nas últimas décadas, e sua prática exige que seus atletas realizem movimentos complexos e de alta intensidade. Objetivo: analisar se a suplementação com gengibre tem efeito ergogênico no poder anaeróbico dos membros (PAMI) em atletas de ginástica aeróbica. Métodos: foi realizado um estudo randomizado, duplo-cego, controlado por placebo, com nove atletas (23,11 + 4,14 anos, 1,63 + 0,09 m, 60,51 + 7,38 kg) da Seleção Brasileira de Ginástica Aeróbica. Após a ingestão de 400 mg de Zingiber officinale ou placebo por sete dias, os indivíduos foram submetidos a um teste de potência anaeróbica (RAST). Os dados de Velocidade de pico e Potência de pico (m/s e W), potência média e mínima (W) e índice de fadiga (W/s e %) foram obtidos no RAST. Resultados: Após verificar a não normalidade da amostra, foi aplicado o Mann-Whitney, mas não foram encontradas diferenças significativas na velocidade de pico da suplementação de gengibre (6,28 ± 0,41 m / s; 445,28 ± 117,15 W) em comparação ao placebo (6,22 ± 0,45 m / s; 425,95 ± 130,39 W). Conclusões: conclui-se que a ingestão de 400 mg de Z. officinale não exerce efeito ergogênico no poder anaeróbico dos membros inferiores de atletas de ginástica aeróbica
