Avian spirochaetosis is caused by Borrelia anserina
- Chickens, turkeys, pheasants, ducks and geese susceptible
- Transmitted by soft ticks of the Argas family, but also via contact with infected material such as blood and tissues
- Transmitted transovarially and trans-stadially via the tick population
- Outbreaks during peak tick activity during warm, humid conditions
- Fever, anaemia and wight loss occurs, with development of paralysis later
- Immunity is serotype specific
- Diagnosis using dark-field microscopy of buffy coat smears or immunodluorescence of blood or tissues
- Giemsa-stained smears and silver impregnation of tissues
- Isolation of borreliae by inoculation of embryonated eggs or chicks
- Antibiotic treatment
- Inactivated vaccines available
