| A adenite equina, também conhecida como garrotilho, é uma enfermidade bacteriana contagiosa, causada por Streptococcus equi, subsp. equi, bactéria β hemolítica do grupo C de Lancefield, que afeta o trato respiratório anterior de equinos de todas as idades, com maior prevalência entre um e cinco anos de idade. Caracteriza-se por produzir secreção mucopurulenta das vias aéreas anteriores e linfadenite dos gânglios retrofaríngeos e submandibulares com formação de abscessos. Fatores de virulência de S. equi, subsp. equi, incluem cápsula de ácido hialurônico, hialuronidase, estreptolisina O, estreptoquinase, receptores para Fc de IgG, peptidoglicano e proteína M. Dentre esses fatores, a proteína M tem especial importância por ser de membrana com propriedades... |

| ABSTRACT: The aim of the present study was to assess the efficacy ofmultiplex PCR in detecting the adulterationof commercially available ground beefvia addition and/orsubstitution ofground buffalo meat. Experimentally adulterated ground beefsamples were prepared in triplicate, and dilutions of DNA from Bos taurus and Bubalusbubalis were prepared to determine the detection limit of the method. Concurrently, 91 ground meatsamples sold as “ground beef” were collected from differentstores in northern Brazil andanalyzed bymultiplex PCR. Buffalo DNA was detected in 17.5% of the collected ground meat samples.Our results showed that multiplex PCR is an efficient method for detectingthe incorporation of groundbuffalo meatatpercentages ranging from 10 to 100% and... |

| Horse Strangles appears frequently in animals vaccinated with commercial bacterins in Rio Grande do Sul, Brazil. Aiming to know the antigenic relationships of strains recovered from sick animals among them and with two vaccines profusely used in the state, bilateral cross reactivity indices (CRI) were estimated. In addition, the immunogenicity of vaccines prepared with field isolates and commercial vaccines was tested in mice. Antibody titers were measured by ELISA and expressed as seroconversions. Thirteen strains of Streptococcus equi subsp. equi, nine classified biochemically as typical and other four as atypical strains, were recovered from 35 sick horses belonging to 10 herds of Rio Grande do Sul, Brazil. The strains recovered from sick horses showed... |

| ABSTRACT The objective of this study was to identify different market segments for buffalo meat with target groups defined in the city of Belém, Pará, Brazil. Paired samples of beef and buffalo meat were given to 447 volunteers, and a sensory analysis of the products was conducted. After the tasting, a questionnaire was administered to obtain demographic (age, educational level, marital status) and economic (household income) data as well as information on the habits of respondents and preferences regarding buffalo meat. The factors were estimated using the principal components method and the factors with characteristic roots greater than one were extracted. To check the suitability of the factorial model, Bartlett’s sphericity test and the... |
