ABSTRACT

O. rhinotracheale is a relatively new bacterium. It is found in commercial fowl and wild birds throughout the world. O. rhinotracheale causes respiratory disease, presenting as pneumonia and air sacculitis. It is transmitted horizontally as well as vertically. O. rhinotracheale is difficult to isolate. Serologically, twelve serotypes can be distinguished, of which serotype A is the most prevalent. Treatment can be difficult, because acquired resistance against the regular antibiotics is common in O. rhinotracheale isolates. An inactivated vaccine for broiler breeders has been developed and for turkeys an inactivated autovaccine can be made.
