A NEW MEMBER OF THE PSITTACOSIS-LYMPHOGRANULOMA GROUP OF VIRUSES THAT CAUSES INFECTION IN CALVES

Abstract

From portions of intestine and feces of apparently normal calves, a virus that produces elementary bodies was procured in guinea pigs and in embryonated eggs. Morphologically and tinctorially this virus closely resembled members of the psittacosis-lymphogranuloma group of viruses and it shared a common antigen or antigens with them. Comparison of serological, pathogenic, and other properties indicated that this virus from calves is a new member of the psittacosis-lymphogranuloma group and in keeping with classification practices it is provisionally named Miyagawanella bovis.
