A case of Chlamydia B (psittacosis) endocarditis is described in a patient with no known previous valve disease. After mitral valve replacement a fall in Chlamydia B antibody titre occurred. At repeat mitral valve replacement five months later for a paravalve leak no evidence of continuing endocarditis was present. Direct confirmation of infection in the patient's apparently healthy budgerigar ...

macrorhabdosis is a debilitating syndrome in budgerigars (melopsittacus undulatus) due to theascomycetous yeast macrorhabdus ornithogaster. in the present study, occurrences of acutemacrorhabdosis resulting in severe mortality in budgerigar fledglings and the effect of differenttreatment regimens for the control of the disease were investigated. the budgerigar (melopsittacusundulates) flock con...

Endogenous hepadnaviruses (hepatitis B viruses [HBVs]) were recently discovered in the genomes of passerine birds. We mined six additional avian genomes and discovered multiple copies of endogenous HBVs in the budgerigar (order Psittaciformes), designated eBHBV. A phylogenetic analysis reveals that the endogenous hepadnaviruses are more diverse than their exogenous counterparts and that the end...
