Sažetak

Porcine Teschovirus (PTV) and Sapelovirus (PSV) are small, nonenveloped RNA viruses belonging to the Picornaviridae family, comprising highly variable and heterogeneous enteric viruses, commonly found in faecal samples from domestic pigs. Infections by PTV and PSV are usually asymptomatic and widespread in domestic pigs. This also appears to be the case in wild boar, though fewer studies have been performed in these wild suids. Occasionally, swine PTV infection results in clinical disease, with the most characteristic outcome being neurological disorders, which can be severe (Teschen disease) or mild (Talfan disease). Reproductive disorders associated with PTV and PSV infection have been termed “SMEDI syndrome” (stillbirth [S],
mummified fetus [M], embryonic death [ED], infertility [I]). Since there are no reports of pig to human transmission, it is considered that PTV and STV have no zoonotic potential. Differential diagnoses are required to exclude pseudorabies (Aujeszky’s disease), classical and African swine fever and porcine reproductive and respiratory syndrome virus. This paper provides an overview of PTV and PSV regarding its history and worldwide geographical distribution etiology, pathogenesis and clinical manifestation, diagnosis, therapy and prevention, with an overview of situation in Croatia.
