The distribution of major histocompatibility complex (MHC) class II positive cells within the connective tissue and the epithelium of the involuted bovine mammary gland has been determined. The effect of intramammary administration of the antigens ovalbumin and formalin killed Streptococcus uberis on the distribution pattern has also been investigated. Infusion of formalin killed S. uberis increased cellular expression of class II antigens when compared with quarters either infused with ovalbumin, not infused at all, or from which minor pathogens had been isolated. The increased expression occurred particularly in the area of the gland cistern-secretory tissue junction.
