- A total of 491 fecal specimens collected from diarrheic piglets in Thailand from January 2011 to March 2014 were screened for group A rotavirus by RT-PCR assay. The G and P genotypes of the detected rotaviruses were determined by multiplex PCR or nucleotide sequencing. Group A rotaviruses were detected in 113 out of 491 (23.0 %) fecal specimens. A wide variety of G-P genotype combinations were identified, and G4P was the most prevalent genotype combination (29.2 %), followed by G4P (14.1 %), G5P (11.5 %), G4P (9.7 %), G3P (7.0 %), G5P (6.1 %), G3P (4.4 %), G3P (2.7 %), and G5P (2.7 %). In addition, the other G-P combinations were also detected at a low percentage, including G3P, G4P, G9P, G9P, G9P, G4P, and G11P strains. This study indicated that group A rotaviruses are a common causes of diarrhea in piglets and a great diversity of G and P genotype combinations are circulating in piglets in Thailand.
