Pathogenesis comparison and cross-protection efficacy of the U.S. PEDV prototype and SINDEL-variant strains in weaned pigs

Two strains (U.S. prototype [P] and S-INDEL-variant [V]) of PEDV are currently circulating in the U.S. Pathogenesis comparison of the two strains in 5-day-old pigs showed that the V-strain was less virulent than the P-strain. However, PEDV pathogenicity is age dependent. Also, understanding the cross-protection between two strains is imperative for PEDV vaccine development. In the current study, the pathogenesis difference and the cross-protection efficacy between the two U.S. PEDV strains were evaluated in weaned pigs.

Combined PCV2 and Mycoplasma hyopneumoniae piglet vaccination has a positive impact on fattener performance compared with M Hyo only in a PCV2 subclinically infected farm

Besides PMWS (Post Weaning Multi-systemic Syndrome) or PCVD-systemic disease, PCV2 is also involved in many subclinical infections. In addition, PCV2 and Mycoplasma hyopneumoniae (Mhyo) infection results in a negative effect on performance. PCV2 and Mhyo vaccinations are an efficient tool to reduce mortality, lesions, viremia and to improve growth.
