| Infectious laryngotracheitis virus (ILTV) cause mild to severe respiratory disease in chickens, the purpose of our study being to use Brazilian isolate of ILTV to reproduce ILTV disease in chickens by experimental infection and to compare three diagnostic methods (nested polymerase chain reaction (PCR), virus isolation, histopathology) for detection of ILTV. Forty-eight chickens intratracheally inoculated with ILTV and a further 48 with PBS, showing mild respiratory signs 48 hours post infection (PI) but no signs of infection after day 10 PI. Every 2 days PI, six birds were arbitrarily selected from the control and infected groups, sacrificed and the trachea collected. Both the nested PCR and virus isolation detected the virus from day 2 until day 12 PI.... |

| 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. |
