Electropherotypes (strains) of porcine rotaviruses from 2 piggeries were determined by polyacrylamide gel electrophoresis of extracted genomic virus RNA. Nineteen electropherotypes were identified during a 3-month period: 9 7 and 3 were from group A presumptive group B or E and C rotaviruses respectively. Analysis of electropherotype distribution based on poggery revealed that 16 electropherotypes were detected in one poggery and 9 in another. More groups A and B or E electropherotypes were detected in one of the 2 piggeries while group C electropherotypes were evenly distributed in both. Common electropherotypes of all the rotavirus groups were present in both piggeries. Our data showed that relatively high degree of genetic variation occurred in rotaviruses especially non-group A viruses infecting Malaysian piglets. The extent of the variation differed in different piggeries and non-group A rotavirus strains were as numerous as group A strains.

Abstract

Electropherotypes (strains) of porcine rotaviruses from 2 piggeries were determined by polyacrylamide gel electrophoresis of extracted genomic virus RNA. Nineteen electropherotypes were identified during a 3-month period: 9 7 and 3 were from group A presumptive group B or E and C rotaviruses respectively. Analysis of electropherotype distribution based on poggery revealed that 16 electropherotypes were detected in one poggery and 9 in another. More groups A and B or E electropherotypes were detected in one of the 2 piggeries while group C electropherotypes were evenly distributed in both. Common electropherotypes of all the rotavirus groups were present in both piggeries. Our data showed that relatively high degree of genetic variation occurred in rotaviruses especially non-group A viruses infecting Malaysian piglets. The extent of the variation differed in different piggeries and non-group A rotavirus strains were as numerous as group A strains.
