Viral agents responsible for CT A-II were sought for decades. CT of type A-II is prevalent in piglets worldwide, occurs as a sporadic disease affecting single litters, as an outbreak over several weeks affecting a high proportion of farrowing’s or as an ongoing problem frequently affecting gilt litters. Other causes of CT occurrence are infections with viral agents like Classical swine fever virus (CSFV), responsible for type A-I. These histological lesions are found as inherited genetic defects in male Landrace pigs in type A-III and in Saddleback pigs in type A-IV. While histopathological lesions are missing in type B, the type A is associated with variable hypomyelination of brain and spinal cord. CT is generally classified in two types of disease. High viral loads were detectable by qRT-PCR in saliva and semen of infected young adults indicating a persistent infection.Ĭongenital tremor (CT) of piglets is a common phenomenon characterized by a generalized shaking involving the whole musculoskeletal apparatus. APPV genomes were detected continuously in piglets that gradually recovered from CT, while the antibody titers decreased over a 12-week interval, pointing towards maternally transmitted antibodies. APPV specific antibodies were identified in sows and in PCR positive piglets affected by congenital tremor (CT). To assess the antibody response a blocking ELISA was developed targeting NS3. APPV could be isolated from a “shaking piglet”, which was incapable of consuming colostrum, and passaged on different porcine cells at very low titers. In confirmation with previous reports, APPV genomes were identified in different body fluids and tissues including the CNS of diseased piglets. A genomic sequence and seven partial sequences were determined and revealed a 90% identity to the US APPV sequences and 92% identity to German sequences. We detected a recently discovered pestivirus, termed atypical porcine pestivirus (APPV) in all these cases by RT-PCR. Histological examination of the CNS of affected piglets revealed moderate hypomyelination of the white substance in cerebellum and spinal cord.
Overall piglet mortality was increased and the number of weaned piglets per sow decreased by more than 10% due to this outbreak. Malnutrition was seen in numerous piglets as a complication of this tremor syndrome.
#CLC SEQUENCE VIEWER 7.6 LICENSE#
Workflows and tools on commercial Workbenches can only be viewed using a commercial Workbench with a valid license installed.ĬLC Workbenches, including CLC Sequence Viewer, are available for Windows, Mac and Linux platforms.In 2013, several Austrian piglet-producing farms recorded outbreaks of action-related repetitive myoclonia in newborn piglets (“shaking piglets”).
Viewing Mode does not require a license and can be used for free. If you have access to a CLC Genomics Server, you can also connect to it and view data held on the server. Using the Viewing Mode of CLC Genomics Workbench, you can also view all data types supported by the CLC Genomics Workbench, such as tracks, heat maps and PCA plots. The analysis and viewing functionalities of the CLC Sequence Viewer are also available by running the CLC Genomics Workbench, version 11.0 and higher, in Viewing Mode. It can also be used to view some of the analysis outputs of CLC commercial workbenches, with the exceptions of some more advanced data types, such as track-based data, and data stored on a CLC Genomics Server.
