A survey of Encephalitozoon cuniculi in laboratory animal colonies in the United Kingdom

Abstract

Of 38 animal colonies serologically examined for Encephalitozoon cuniculi, 1 mouse, 2 rat and 4 guineapig colonies were positive. A further survey showed that the prevalence within mouse, rat, guineapig and rabbit colonies varied between 25 and 95%. Guineapigs housed with infected rabbits are at a greater risk of being infected than those housed separately. Nephritis was a common feature, but cerebral granulomata were not seen. © 1980, Royal Society of Medicine Press. All rights reserved.
