Vaccination of chickens against Ornithobacterium rhinotracheale infection.
Vaccination of young broilers with inactivated vaccines against experimental Ornithobacterium rhinotracheale challenge was found to be effective, but the results of vaccination were influenced, in a negative way, by the presence of maternal antibodies. The use of a strong adjuvant, such as mineral oil, in a bacterin was necessary to obtain good protection when maternal antibodies were present. ...
متن کاملCharacterization of Ornithobacterium rhinotracheale Isolates from Commercial Chickens
Ornithohac/erium rhino/rachea/e (ORT) is a relatively rceently diseovered bacterium. which it is associated with respiratory diseases, Tracheal samplcs from carcasses of 100 roultry tlocks submitted to Razi Institute were examined for ORT isolation. Ali these tlocks were affected with respiratory disorders. Colonies of ORT were detected after 24h of incubation and identification of ORT isolates...
متن کاملOrnithobacterium rhinotracheale and Mycoplasma synoviae in broiler chickens in Jordan.
A cross-sectional study was conducted from November 2008 to July 2010 in commercial broiler flocks in southern (n = 50) and northern (n = 50) areas of Jordan, to determine the flock-level prevalence of Ornithobacterium rhinotracheale (ORT) and Mycoplasma synoviae (MS) infections. Tracheal swabs were collected from commercial broilers with respiratory disease and tested by polymerase chain react...
متن کاملExperimental infection in turkeys and chickens with Ornithobacterium rhinotracheale.
Ornithobacterium rhinotracheale was found to cause growth retardation in both turkeys and chickens after experimental intra-air sac administration and to cause growth retardation together with airsacculitis and pneumonia after aerosol administration. Both turkey and chicken isolates of O. rhinotracheale were able to induce the same kind of respiratory inflammations and weight-gain losses in chi...
متن کاملRandom amplified polymorphic DNA (RAPD) analysis of Ornithobacterium rhinotracheale strains isolated from chickens in Turkey
Six field strains of Ornithobacterium rhinotracheale isolated from chickens in Elazig province located in the East of Turkey were typed by serotyping and random amplified polymorphic DNA assay using a random primer (OPG-11). Using the AGP test used for serotyping, serotype A was found to be the predominant serotype, only one strain was serotyped as serotype B. By RAPD assay, the tested ORT stra...
