Abstract
Fowl adenovirus infections are widely prevalent in poultry. Many of the viruses can infect chickens without resulting in overt disease. Nevertheless, some fowl adenoviruses can cause important disease complexes in chickens such as incluusion body hepatitis, hydropericardium syndrome, necrotic pancreatitis, and gizzard erosion. Adenoviral gizzard erosions have been regularly reported from Japan, but detailed reports from Europe are scarce and available only from Italy, Poland, Hungary, and Germany. This case report describes two concurrent outbreaks of gizzard erosions caused by fowl adenovirus A in two Belgian broiler farms. Clinical signs observed were signs of depression, reduced feed intake, reduced weight gain, and lack of uniformity of the flocks. At necropsy, typically multiple erosions within the koilin layer of the gizzard were observed. Histopathological examination showed a multifocal, erosive ventriculitis with basophilic intranuclear inclusions in the epithelium. PCR analysis confirmed the diagnosis of fowl adenovirus. These findings suggest that outbreaks of adenoviral gizzard erosion can also lead to significant economic losses in Belgium.
