The aim of this study was to determine the differences in the antimicrobial susceptibility profiles of Moraxella bovis, M. bovoculi and M. ovis. Thirty-two strains of Moraxella spp. isolated from cattle and sheep with infectious keratoconjunctivitis were tested via broth microdilution method to determine their susceptibility to ampicillin, cefoperazone, ceftiofur, cloxacillin, enrofloxacin, florfenicol, gentamicin, neomycin, oxytetracycline and penicillin. The results demonstrated that Moraxella spp. strains could be considered sensitive for most of the antimicrobials tested in this study, but differences between the antimicrobial susceptibility profiles of these three Moraxella species were found. M. bovis might differ from other species due to the higher... |

A discutida questão da substituição do uso de antibacterianos em rações (promotores de crescimento) requer urgentes alternativas. Face às necessidades de inibidores microbianos nesses alimentos, os óleos essenciais (OES) se constituem em alternativa, sob avaliação. Neste estudo, avaliou-se a atividade antimicrobiana dos OES de Origanum vulgare (orégano), Thymus vulgaris (tomilho), Cinnamomum zeylanicum (canela), Lippia graveolens (orégano mexicano), Zingiber officinale (gengibre), Salvia officinalis (sálvia), Rosmarinus officinalis (alecrim) e Ocimum basilicum (manjericão) frente a amostras de Escherichia coli isoladas de fezes de aves (n=43) e de bovinos (n=36). A concentração inibitória mínima (CIM) e a concentração bactericida mínima (CBM) foram... |

Records of in vitro susceptibility tests performed between 1992 and 2011 were retrospectively reviewed in order to evaluate the dynamic profiles of possible changes in antimicrobial resistance of Staphylococcus spp. isolated from milk samples of cows with mastitis during two decades. The results of 2,430 isolates tested by disk diffusion technique for susceptibility to oxacillin, penicillin, ampicillin, cephalexin, norfloxacin, tetracycline, sulfazotrim, gentamicin, and neomycin were analysed. Comparisons were performed between the percentages of resistance to antimicrobials and their classes and also between the decades studied. Additionally, the possible tendency or changes in the behaviour of these pathogens against the major drugs used in the last two... |
