===Avian spirochaetosis===
*Caused by ''Borrelia anserina''
*Acute, endemic disease of birds in tropical and subtropical regions
*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
