Rotaviral diarrhoea in kids of Black Bengal goats in Mymensingh

Abstract

An epidemiological study on rotavirus infection was carried out by examining 484 faecal specimens of kids of Black Bengal goats using RNA polycrylamide-gel-electrophoresis and silver staining (PAGE-ss) technique. Goat rotavirus was detected in 8.68% (42/484) diarrhoeic faecal specimens. The highest rate of rotavirus infection in goat kids was found in the month of January (13.95%) and the lowest in August (5.26%). The rate of rotavirus infection also the highest in winter season (11.80%) and the lowest in summer season (7.10%). The kids of 7 days to 1-month age group were most frequently found associated with rotavirus infection 13.63% (12/95), but very young kids which were below 7 days old, were found negative for rotavirus while gradual decreasing infection rate was found with the advancement of age. There was no marked variation in rotavirus infection rate between male and female group of kids. An electrophoretic analysis of rotaviral RNA revealed that kids were infected with rotavirus having only long RNA electropherotypes. The antigenic studies with reference to subgroup and serotypes with specificity and its zoonotic potentials need to be studied further.
