Diagnosis and Treatment of Gordonia Species Infection in a Peach-Faced Lovebird ( Agapornis roseicollis ).

Respiratory distress is a common presentation for avian species. A 9-week-old peach-faced lovebird () was presented with a 2-week history of progressive dyspnea. Computed tomographic (CT) images were suggestive of splenomegaly and bilateral granulomatous pulmonary disease. Polymerase chain reaction testing of samples from the choana, cloaca, and distal tracheal/syringeal area were positive for species . A comparison search of the 400 base pair sequence in the NCBI/BLAST/blastn database revealed a best match of 93% similarity to species and 91% similarity to . is a genus in the phylum Actinomycetota, the same lineage that includes species. species can be mistaken for species unless more definitive diagnostic testing is pursued. Infection caused by species is rare in humans. Reports commonly cite infection of immunocompromised patients, and to our knowledge, no reports of treatment have been published in the veterinary literature. After the test results were obtained, the patient was treated with azithromycin and pradofloxacin for 3 months. The lovebird was presented for reexamination when the antibiotic treatment was complete. When reexamined, and a second series of CT images evaluated, it was determined that the treatment achieved clinical resolution of signs and lesions.
