High resolution melting analysis (HRM) for the assessment of clonality in feline B-cell lymphomas.

Unlabelled: Analysis of clonality is gaining importance in diagnosing lymphomas in veterinary medicine. Usually, PCR for the analysis of antigen receptor rearrangement (PARR) is followed by electrophoretic separation of the PCR products. Aim of this study was to test the feasibility of HRM for the assessment of clonality in B-cell lymphomas of cats.

Detection of canine adenovirus 1 in red foxes ( Vulpes vulpes) and raccoons ( Procyon lotor) in Germany with a TaqMan real-time PCR assay.

We developed a real-time (rt)PCR assay based on TaqMan probe technology for the specific detection of canine adenovirus 1 (CAdV-1). The assay is able to detect three 50% tissue culture infectious dose/mL in CAdV-1-containing cell culture supernatant. Viral genomes were not amplified of canine adenovirus 2 or of several bovine, porcine, and avian adenoviruses.

Identification of a novel feline large granular lymphoma cell line (S87) as non-MHC-restricted cytotoxic T-cell line and assessment of its genetic instability.

Feline large granular lymphocyte lymphomas are rare but very aggressive tumors with a poor prognosis. In this study, a cell line from an abdominal effusion of a cat with large granular lymphoma was characterized. Immunophenotype staining was positive for CD3 and CD45R, and negative for CD4, CD8, CD56, CD79α, BLA.
