A gram-negative motile non-fermentative and aerobic bacterium involved in upper respiratory tract disease in avian and mammalian species.


Bordetella avium is implicated in upper respiratory tract disease in avian species particularly turkeys manifested with whooping cough similar to the sign and symptoms of bordetellosis wherein in an onset of infections morbidity reach up to 100% within 24 hours yet mortality rate is low but it will increase if concurrent infections is present and ventilation as well as environmental conditions is poor.

Bordetella avium is extremely contagious and easily transmitted by direct contact in which an outbreak of infections includes coughing, presence of foamy conjunctivitis, sneezing, oculonasal discharge and open mouth breathing.

Bordetella avium has been associated recently with respiratory infections in humans and is though that this bacterium is strictly animal pathogens in wild and domesticated birds but human infections reported with an individual having cystic fibrosis and pneumonia thus confer that this particular bacterium is an opportunistic human pathogens.
