Technical Abstract: Avian chlamydiosis is a disease caused by the bacterium Chlamydophila psittaci. There are at least 6 known serotypes, each having a predilection for different species of birds. It affects all types of wild and domestic birds, but mostly ducks, turkeys, pigeons, and pet birds. Many cases are mild, resulting in persistent infections, but death rates of 40-60% are common in flocks not treated. It is a serious public health problem because humans often become infected following exposure to infected birds. The most common sources of human exposure are ducks and turkeys in slaughter houses, pigeons on the farm, and pet birds. In humans, the disease will vary from asymptomatic to fatal if treatment is delayed. The chapter covers the classification, structure, host range, and transmission of the organism. It also covers the clinical and pathological signs, diagnosis, and control in poultry.
