Reproduction of adenoviral gizzard erosion by the horizontal transmission of fowl adenovirus serotype 1.
The horizontal transmission ability of fowl adenovirus (FAV) serotype 1 99ZH strain, isolated from chickens exhibiting gizzard erosion, was investigated. Twelve 13-day-old specific pathogen-free chickens were inoculated orally with 10(6) TCID(50)/0.05 ml of the strain. An in-pen contact group (chickens in the same pen with inoculated chickens), hedge contact group (chickens in a pen connected w...
متن کاملAdenoviral gizzard erosions in Italian chicken flocks.
TYPE 1 avian adenoviruses belong to the genus Aviadenovirus within the adenovirus family. Five species of fowl adenovirus (fAdV) (designated by the letters A to E) are recognised within the Aviadenovirus genus based largely on molecular criteria, in particular restriction enzyme fragmentation patterns and sequencing data (McFerran and McConnel Adair 2003). fAdV are common infectious agents in p...
متن کاملAn outbreak of gangrenous dermatitis in commercial broiler chickens.
The present report describes an outbreak of gangrenous dermatitis (GD) infection in a commercial poultry farm in Delaware involving 34-day-old broiler chickens. In addition to obvious clinical signs, some GD-affected broilers also showed severe fibrino-necrotic enteritis and large numbers of Gram-positive rods in the necrotic tissue. Histopathological findings included haemorrhage, degeneration...
متن کاملAssociation between gizzard lesions and increased caecal Clostridium perfringens counts in broiler chickens.
The aim of this study was to investigate the relationship between mucosal gizzard lesions and caecal Clostridium perfringens counts. Gross pathological changes in the gizzard and small intestine, and caecal C. perfringens counts from 1217 meat-type chickens were recorded during the course of six experiments and were statistically analysed. C. perfringens counts increased significantly (P < 0.00...
متن کاملPhylogenetic Analysis of Fowl Adenoviruses Isolated from Chickens with Gizzard Erosion in Japan
Thirty-four fowl adenoviruses (FAdVs) isolated from chickens with gizzard erosion (GE) from 1999 to 2010 were characterized phylogenetically together with foreign isolates. The phylogenetic analysis based on part of the hexon gene classified these 34 FAdV isolates into 3 groups: FAdV-1, -8a and 8b, thereby suggesting that FAdVs associated with GEs in chickens are diverse. All 30 FAdV-1 isolates...
