| Over the years, Salmonella Heidelberg (SH) has gained prominence in North America poultry production and in the poultry production of other countries. Salmonella Heidelberg has been isolated and reported from poultry and poultry products in Brazil since 1962, whereas Salmonella Enteritidis (SE) has only emerged as a serious problem in poultry and public health since 1993. These strains of Salmonella can cause intestinal problems in newly hatched chicks, and infection may persist until adulthood. Upon slaughter of chickens, Salmonella can contaminate carcasses, a condition that poses a threat to human health. The aim of this study was to compare the fecal excretion of Salmonella Enteritidis and Salmonella Heidelberg in newly hatched chicks (orally... |

| Abstract Pasteurella multocida causes atrophic rhinitis in swine and fowl cholera in birds, and is a secondary agent in respiratory syndromes. Pathogenesis and virulence factors involved are still poorly understood. The aim of this study was to detect 22 virulence-associated genes by PCR, including capsular serogroups A, B and D genes and to evaluate the antimicrobial susceptibility of P. multocida strains from poultry and swine. ompH, oma87, plpB, psl, exbD-tonB, fur, hgbA, nanB, sodA, sodC, ptfA were detected in more than 90% of the strains of both hosts. 91% and 92% of avian and swine strains, respectively, were classified in serogroup A. toxA and hsf-1 showed a significant association to serogroup D; pmHAS and pfhA to serogroup A. Gentamicin and... |

| Cytodites nudus e Laminosioptes cysticola são ácaros cuja ocorrência é pouco relatada e cuja infestação simultânea nunca foi descrita na literatura científica brasileira. C. nudus é conhecido como ácaro dos sacos aéreos e pode provocar sinais respiratórios, pneumonia e emagrecimento, quando presente em grande número no hospedeiro. L. cysticola parasita o tecido conjuntivo de galiformes e provoca a formação de pequenos nódulos subcutâneos calcificados, que podem ser confundidos com nódulos de tuberculose aviária. No presente trabalho, são discutidos os aspectos patológicos das lesões causadas pelos ácaros C. nudus e L. cysticola e a caracterização morfológica desses parasitas. |

| Fourty eight isolates of Arcobacter spp were obtained from 37 poultry carcasses, from abattoir, among 80 carcasses examined. Attempts for culturing were made from the skin and muscle, resulting on 25 positive cultures from muscle and 23 from skin. Classification was achieved by phenotypic characterization and PCR and multiplex PCR, resulting 41 samples of Arcobacter butzleri and 07 Arcobacter sp. This is the first report on the occurrence of Arcobacter in animal carcasses in Brazil. |
