Psittacosis/avian chlamydiosis

Abstract

Considerable progress continues to be made in understanding chlamydial organisms, their host species, diagnosis, and treatment.1-3 Thus, national guidelines are updated annually to provide a standardized approach to handling infections in humans and birds.2-3 Prior to development of these guidelines, considerable variation in approach by state agencies has been documented.39 A more recent national assessment of state regulations and procedures has not been conducted. Decreasing imports of birds and increasing education may contribute to a reduction in human risk from avian infections. Keeping new birds separate from old birds in aviaries and poultry production facilities may reduce the incidence of avian chlamydiosis. Although wide-scale testing of birds may not be cost effective,28 focal testing and treatment may help reduce human risk. The recent loss of a major source for pelleted feed for small birds, such as budgerigars, was a severe setback for veterinarians and local agencies in managing this disease. However, new medication formulas under development may help to address this problem.
