Isolation and Phylogenetic Analysis of Atypical Porcine Pestivirus Isolates Identified in Russian Swine Herds. [PDF]

Viruses
Atypical porcine pestivirus (APPV) was first identified in 2015 in North America by high-throughput sequencing. APPV is associated with congenital tremor A-II and is widely distributed worldwide. In this study, a total of 2630 samples of domestic pigs obtained from 14 regions of Russia from 2020 to 2024 were screened for APPV presence by qRT-PCR.

Detection and localization of atypical porcine pestivirus in the testicles of naturally infected, congenital tremor affected piglets. [PDF]

Transbound Emerg Dis, 2022
Abstract Atypical porcine pestivirus (APPV) belongs to the genus Pestivirus within the family Flaviviridae. Recently, APPV has been identified as the causative agent of congenital tremor (CT) type AII. The disease is a neurological disorder that affects newborn piglets and is characterized by generalized trembling of the animals and often splay legs ...

Characterization of the Humoral Immune Response Induced after Infection with Atypical Porcine Pestivirus (APPV). [PDF]

Viruses, 2019
Atypical porcine pestivirus (APPV) is a widely distributed pathogen causing congenital tremor (CT) in piglets. So far, no data are available regarding the humoral immune response against APPV. In this study, piglets and their sows from an affected herd were tested longitudinally for viral genome and antibodies.

Evolution and genetic diversity of atypical porcine pestivirus (APPV) from piglets with congenital tremor in Guangxi Province, Southern China. [PDF]

Vet Med Sci, 2021
The complete genomic sequences of five APPV strains were obtained from positive clinical tissue samples from neonatal piglets with CT in Guangxi province, Southern China. The five APPV strains distributed in two clades in phylogenetic trees based on complete genome, Npro, Erns and E2 gene sequences, respectively, which indicated that APPV strains from ...

Genotyping atypical porcine pestivirus using NS5a

Infection, Genetics and Evolution, 2021
Atypical porcine pestivirus (APPV) is an emerging virus discovered in 2014 and it can cause congenital tremors in pigs. Molecular epidemiology serves as an essential tool in monitoring and controlling the disease. Virus epidemiology mainly relies on genome sequencing and phylogenetic characterization.

Atypical Porcine Pestivirus as a Novel Type of Pestivirus in Pigs in China [PDF]

Frontiers in Microbiology, 2017
Pestiviruses are highly variable RNA viruses. A growing number of novel pestiviruses has been discovered in domestic and wild species in the last two decades. Recently, a novel atypical porcine pestivirus (APPV) linked with the development of congenital tremor (CT) in neonatal pigs was described in Europe and the Americas.

Expert opinion on the identification, risk assessment, and mitigation of microorganisms and parasites relevant to xenotransplantation products from pigs

Xenotransplantation, Volume 30, Issue 5, September/October 2023., 2023
Abstract Xenotransplantation has the potential to address shortages of organs available for clinical transplantation, but concerns exist regarding potential risks posed by porcine microorganisms and parasites (MP) to the health of human recipients. In this study, a risk‐based framework was developed, and expert opinion was elicited to evaluate porcine ...

Assessment on the efficacy of methods 2 to 5 and method 7 set out in Commission Regulation (EU) No 142/2011 to inactivate relevant pathogens when producing processed animal protein of porcine origin intended to feed poultry and aquaculture animals

EFSA Journal, Volume 21, Issue 7, July 2023., 2023
Abstract An assessment was conducted on the level of inactivation of relevant pathogens that could be present in processed animal protein of porcine origin intended to feed poultry and aquaculture animals when methods 2 to 5 and method 7, as detailed in Regulation (EU) No 142/2011, are applied.
