| This study aimed at the antibody production by intestinal mucosa of broilers chicks were orally inoculated with Lactobacillus spp. at one and/or 21 days of age, and subsequently challenged with Salmonella enterica, subspecies enterica, serotype Enteritidis (S. Enteritidis). A total number of 288 drug-free broiler chicks was divided into 6 groups (groups A, B, C, D, E, and F), according to age at Lactobacillus spp. inoculation and SE challenge. The intestinal mucosa immune response was determined as the production of immunoglobulin A against S. Enteritidis, and evaluated by the Enzyme-Linked Immunosorbent Assay (ELISA) technique in intestinal washing fluid. Groups treated with Lactobacillus spp. presented higher IgA production only when the chicks were... |

| Avaliou-se a contaminação da casca e do conteúdo interno de ovos inoculados com Salmonella enterica sorovar enteritidis fagotipo 4, lavados com água de torneira (AT) ou solução de amônia quaternária (AQ) e armazenados a 8ºC e 25ºC. Duzentos e cinqüenta e dois ovos foram divididos em três grupos. Os tratamentos de cada grupo consistiram de imersão em AT, AQ a 25ºC e a 43ºC. Após a secagem natural, todos os grupos foram contaminados com solução de S. enteritidis. Seguindo-se a contaminação, cada grupo tratado foi estocado a 8ºC ou 25ºC, e a presença de S. enteritidis na casca e no conteúdo interno foi avaliada após zero, 24, 96 e 168 horas. A sanitização com AQ mostrou-se eficiente na redução de S. enteritidis nas cascas dos ovos. O armazenamento dos ovos a... |

| ABSTRACT Salmonellosis is a globally important zoonosis, and Salmonella Heidelberg is one of the most prevalent serovars in poultry production worldwide, as well as in food poisoning cases. Antimicrobial drugs were previously widely used to face health challenges in animal production; however, since their ban as performance enhancers, many alternative strategies have been proposed. One of these strategies is the use of plant extracts, such as those containing the alkaloids benzophenanthridine and protopine. These compounds have antimicrobial, anti-inflammatory, immunomodulation, and nutritional effects. The objective of the present study was to evaluate the effects of the supply of a product containing benzophenanthridine and protopine (Sangrovit(r)WS 100... |
