Differences in the pathogenicity of Chinese virulent genotype GIIa and GIIb porcine epidemic diarrhea virus strains and the humoral immune status of one- and two-month-old weaned pigs infected with these strains.

Abstract excerpt

We evaluated differences in the pathology and humoral immune status in one- and two-month-old weaned pigs infected with virulent Chinese genotype GIIa and GIIb strains of porcine epidemic diarrhea virus (PEDV). All pigs infected with the GIIa strain developed severe diarrhea (100%), while the morbidity of the GIIb strain in one- and two-month-old weaned pigs was 80% (4/5) and 40% (2/5), respectively. There was no...
