Gizzard Erosion in Growing Chickens

Phylogenetic 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...

First Report of Coccidiosis and Gizzard Erosion in a Zebra Finch (Taeniopygia guttata) of Iran

Coccidiosis and gizzard erosion are rare conditions in cage bird. A male zebra finch was presented with a history of watery diarrhea, anorexia, ruffled feathers, weight loss, and lethargy and died finally. Gross necropsy revealed small areas of erosions and hemorrhages on the gizzard wall. The intestine was oedematous. The spleen appeared pale and small. The testes were asymmetric.Histologicall...

A condition of erosion and ulceration of young chickesn's gizzard in Iran

Association 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...

Outbreak of gizzard erosion associated with fowl adenovirus infection in Korea.

The pathogenicity of a fowl adenovirus serotype-1 (FAdV-1, K181 strain) isolated from a case of gizzard erosion in layer chickens was investigated in specific-pathogen-free (SPF) chicks. One-week-old SPF chicks were inoculated orally or intramuscularly with the isolate of FAdV-1 and euthanized for necropsy at 7, 14, and 21 d postinoculation. Although there were no clinical signs after inoculati...
