This report describes the clinical progression of a Quarter Horse filly with common variable immunodeficiency (CVID). Equine CVID is a primary immunodeficiency in which affected animals are unable to mount an appropriate antibody response and suffer recurrent bacterial infections. The filly in this report had a history of chronic respiratory tract infections but presented for assessment of poor weight gain and was diagnosed with Actinobacillus equuli peritonitis.
