Avian Pox in Native Captive Psittacines, Brazil, 2015

Area of Science:

• Veterinary Virology
• Avian Diseases
• Conservation Medicine

Background:

• Avian pox is a viral disease affecting birds, caused by avipoxviruses.
• Psittacines, or parrots, are susceptible to various poxvirus infections.
• Conservation facilities are crucial for protecting endangered avian species and managing disease outbreaks.

Purpose of the Study:

• To investigate an outbreak of avian pox in psittacine birds within a conservation facility.
• To determine the prevalence of psittacine pox virus in both sick and healthy birds.
• To identify the need for further characterization of detected poxvirus isolates.

Main Methods:

• Examination of 94 birds from 10 psittacine species.
• Inclusion of both clinically affected and apparently healthy individuals in the study.
• Detection of psittacine pox virus through diagnostic testing.

Main Results:

• Psittacine pox virus was identified in 23 out of 27 (85.2%) sick birds.
• The virus was also detected in 4 out of 67 (6.0%) healthy birds.
• These findings suggest widespread circulation of the virus within the facility.

Conclusions:

• Avian pox virus was prevalent in the studied psittacine population during the outbreak.
• The presence of the virus in healthy birds highlights the importance of surveillance and biosecurity measures.
• Further molecular characterization of the psittacine pox virus isolates is essential for understanding its epidemiology and for developing targeted control strategies.
