RESUMOBactérias do gênero Salmonella fazem parte da flora normal das aves e sua ocorrência em produtos avícolas varia com o manejo na criação e tecnologia de abate, representando riscos para o consumidor final e dificuldades nas exportações. A S. Heidelberg parece ser mais invasiva e causar doenças com maior gravidade que outros sorovares paratíficos. Este trabalho teve por objetivos pesquisar Salmonella em diferentes pontos da tecnologia de abate de frangos e relatar o isolamento de S. Heidelberg em um abatedouro sob inspeção federal. S. Heidelberg foi isolada em frangos logo após a depenagem e na água do chiller indicando que, embora não tenha sido realizado o isolamento em outros pontos amostrados, a bactéria estava presente no ambiente e poderia contaminar carcaças prontas para consumo, com reflexos na saúde pública. O isolamento de S. Heidelberg reforça esta preocupação uma vez que este sorovar tem se destacado como causador de doenças transmitidas por alimentos.PALAVRAS-CHAVE: Salmonella Heidelberg, abatedouros, frangos de corte.ABSTRACT SALMONELLA HEIDELBERG ISOLATED AT DIFFERENT POINTS OF THE BROILER SLAUGHTERHOUSE. Bacteria of the genus Salmonella are part of the normal flora of poultry, and its occurrence in poultry products varies with the production management methods and slaughter technology, representing risks to the consumer and difficulties in exports. S. Heidelberg appears to be more invasive and to cause more severe disease than other non-typhoidal serovars. The objective of the present study was to search for Salmonella at different points of the slaughterhouse and to report on the isolation of S. Heidelberg in a slaughterhouse under federal inspection. S. Heidelberg was isolated in poultry soon after feathering-out and in the chiller water, indicating that, although it was not isolated at another sampled points, the bacteria was present in the environment and could contaminate carcasses ready for consumption, with an impact on public health. This concern is underscored by the fact that S. Heidelberg is a proven causative agent of foodborne infections.
57 MPN/mL and the dilution 10-6 was equal to 30 MPN/mL. There was a correlation between the counts used for the artificial contamination of the samples and those recovered by mMPN, indicating that the method A was sensitive for the enumeration of different levels of contamination of the meat matrix. In method B, there was no correlation between the inoculated dilutions and the mMPN results.]]>
Two cases of thyroiditis due to Brucella melitensis are reported. Both occurred in foreigners working in Switzerland and presented with characteristic symptoms of thyroiditis which masked those of brucellosis. Cultures were diagnostic. One patient had concomitant thyroid malignancy. Both showed normal thyroid function and were cured following antibiotic treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
