Abstract
OBJECTIVE: Evaluation of the clinical efficacy of doxycycline application via drinking water in the treatment of chlamydiosis in infected, clinically ill flocks of racing and fancy pigeons (Columba livia f. domestica) under field conditions. MATERIAL AND METHODS: In the scope of a field study, 13 pigeon flocks with clinically manifest ornithosis were treated over a period of 25 days with a novel doxycycline formulation via drinking water. Infection with Chlamydia psittaci had been confirmed beforehand by molecular-biological investigation of organ material from dissected pigeons in each flock. Therapeutic success was evaluated by PCR-analysis of triple swabs from 10 animals of each flock on day 25 of treatment and 7 days after completion of the therapy, as well as by repeated individual and daily herd examination. RESULTS: The causative agent Chlamydia psittaci together with additionally documented atypical chlamydia species in six of the 13 flocks could thereby no longer be detected. Furthermore, a resolution of clinical symptoms was achieved in each of the treated pigeon flocks. CONCLUSION: Application of doxycycline in the described therapy regimen proved successful for the treatment of ornithosis. In addition, excellent acceptance and tolerance of the deployed formulation could be confirmed in praxis.
