Circovirus-Like Infection in a Pigeon

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. Methods: Forty-five samples were collected from different non-psittacine species belonging to seven avian o...

Malignant Fibrous Histiocytoma in a Pigeon

Case Description- A pigeon with an abnormal mass on right wing was referred to the Veterinary Clinic of Shahid Bahonar University of Kerman. Treatment and Outcome- The mass was removed surgically and histopathologic examination was done. Microscopic findings revealed a stori-form pattern of atypical and pleomorphic spindle-shape tumor cells with histiocytes and too many thick wall capillari...

Unique Circovirus-Like Genome Detected in Pig Feces

Using a metagenomic approach and molecular cloning methods, we identified, cloned, and sequenced the complete genome of a novel circular DNA virus, porcine stool-associated virus (PoSCV4), from pig feces. Phylogenetic analysis of the deduced replication initiator protein showed that PoSCV4 is most related to a fur seal feces-associated circular DNA virus.

Transcriptional analysis of porcine circovirus-like virus P1

BACKGROUND Recently identified porcine circovirus-like virus P1 has the smallest DNA viral genome. In this study, we identified the viral genes and their corresponding mRNA transcripts. RESULTS The RNAs of P1, synthesized in porcine kidney cells, were examined with northern blotting and PCR analyses. Eight virus-specific RNAs were detected. Four mRNAs (open reading frames (ORFs) 1, 2, 4, and ...
