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
