Porcine rotavirus infection patterns from 2 distantly situated piggeries were studied. Faecal samples collected over a period of 3 months were analyzed by RNA electrophoresis and silver staining. Rotaviruses were detected from 157 piglets (33) from a total of 481 diarrhoeic animals aged 1 to 5 weeks. Six of 74 non-diarrhoeic animals (8) were rotavirus-positive. Based on electropherotic patterns 78 (23 of total animals tested) and 12 (3.4) of the viruses were identified as group A and C rotaviruses respectively while 10 (2.8) were probable group B or E rotaviruses. In the two piggeries group A rotavirus infections were rather similar in prevalence and age distribution but non-group A rotavirus infections were dissimilar in these 2 aspects and also in the proportion of the rotavirus groups detected. Piglets from 9 out of the 11 serial sow parity groups examined conformed to a pattern in which the prevalence of rotaviru-associated diarrhoea in piglets showed a dicreasing trend with increasing sow parity number until the sixth parity thereupon high prevalence was maintained with increasing parities.

Abstract

Porcine rotavirus infection patterns from 2 distantly situated piggeries were studied. Faecal samples collected over a period of 3 months were analyzed by RNA electrophoresis and silver staining. Rotaviruses were detected from 157 piglets (33) from a total of 481 diarrhoeic animals aged 1 to 5 weeks. Six of 74 non-diarrhoeic animals (8) were rotavirus-positive. Based on electropherotic patterns 78 (23 of total animals tested) and 12 (3.4) of the viruses were identified as group A and C rotaviruses respectively while 10 (2.8) were probable group B or E rotaviruses. In the two piggeries group A rotavirus infections were rather similar in prevalence and age distribution but non-group A rotavirus infections were dissimilar in these 2 aspects and also in the proportion of the rotavirus groups detected. Piglets from 9 out of the 11 serial sow parity groups examined conformed to a pattern in which the prevalence of rotaviru-associated diarrhoea in piglets showed a dicreasing trend with increasing sow parity number until the sixth parity thereupon high prevalence was maintained with increasing parities.
