Objectives: Nidoviruses have recently been described as a putative cause of severe respiratory disease in pythons in the USA and Europe. The objective of this study was to establish the use of a conventional PCR for the detection of nidoviruses in samples from live animals and to extend the list of susceptible species. Materials and methods: A PCR targeting a portion of ORF1a of python nidoviruses was used to detect nidoviruses in diagnostic samples from live boas and pythons. A total of 95 pythons, 84 boas and 22 snakes of unknown species were included in the study. Samples tested included oral swabs and whole blood. Results: Nidoviruses were detected in 27.4% of the pythons and 2.4% of the boas tested. They were most commonly detected in ball pythons (Python [P.] regius) and Indian rock pythons (P. molurus), but were also detected for the first time in other python species, including Morelia spp. and Boa constrictor. Oral swabs were most commonly tested positive.

Abstract
Tissue fibrosis as complication of diabetes mellitus is known in humans. Because TGF-β1induces fibrosis and is elevated in humans suffering from diabetes mellitus we measured this growth factor in serum of dogs with diabetes mellitus and compared it with healthy dogs and those with fibrotic diseases. Further we measured the expression of TGF-β1receptor on lens capsule to investigate possible association between diabetes mellitus and cataract associated alterations. TGF-β1 was measured in serum of 12 dogs with diabetes mellitus, 20 healthy controls and 12 dogs with fibrotic diseases. Dogs with diabetes mellitus and fibrotic diseases have significantly increased TGF-β1 serum concentrations compared to healthy controls. Some dogs with diabetes mellitus showed increased expression of TGF-β1 receptor in lens capsule. Based on our observations we can conclude that TGF-β1 elevation in dogs with diabetes mellitus may induces complications of the disease and may participates on lens alteration.
