A Cross-Sectional Survey of Gastrointestinal Parasites in an Ornithological Garden.

Captive birds in collections may be infested with a wide range of parasites. Globally, information on parasitic infections and their health implications in ornithological collections are scarce. In the present study, the prevalence of parasitic infections in an ornithological garden in Tehran was investigated.

Molecular survey of avian circoviruses in some non-psittacine birds and detection of a novel canary circovirus in a pigeon.

Background: Circoviruses are small, non-enveloped, single stranded DNA viruses. There is scarce information about these agents in non-psittacine birds.

Aims: It is attempted to detect and characterize circoviruses in non-psittacine birds.

Molecular detection and characterization of beak and feather disease virus in psittacine birds in Tehran, Iran.

Beak and feather disease virus (BFDV), a member of genus circovirus, is a small, non-enveloped, single stranded DNA virus. Although BFDVs are among the most well studied circoviruses, there is little to no information about BFDVs in Iran. The aim of the present study was to detect and identify BFDV molecules from the birds referred to the avian clinic of The Faculty of Veterinary Medicine, Tehran University, Iran.

Concurrent atypical diffused tuberculosis and macrorhabdosis in a canary (Serinus canaria).

A dead canary from a mixed species zoological garden was presented for diagnostic necropsy. Cachexia with prominent atrophy of pectoral muscles, yellowish brown discoloration of the liver and kidney, dark brown to black intestinal contents and moderate proventricular dilatation with some degree of catarrhal gastritis were the significant macroscopic findings. Parenchymatous organs like the liver, the spleen, the lung and the kidneys were extremely affected by massive diffuse necrosis and heavy infiltration of mononuclear inflammatory cells, histopathologically.
