Ornithobacterium 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 کاملSeroprevalence and identification of Ornithobacterium rhinotracheale from broiler and broiler breeder flocks in Thailand.
Ornithobacteriosis is an infectious disease of avian species that has been reported in almost all countries around the world, except Thailand. The objectives of this study were to determine the seroprevalence of Ornithobacterium rhinotracheale (ORT) and to isolate and identify ORT in broilers and broiler breeders in Thailand. Chicken antibodies had been randomly checked from 17 farms (19 flocks...
متن کاملsurvey of prevalence of ornithobacterium rhinotracheale in broiler farms affected with respiratory disorders in karkazi province
respiratory diseases are considered as common disorders in broiler farms. over the past decade a pleomorphic gram negative bacteria which isolated from broilers with respiratory diseases now calls ornithobacterium rhinotracheale . in this study, samples from trachea and lung collected from chicken with clinical respiratory signs in 173 broiler farms and then subjected on bacterial culture. the ...
متن کاملLongitudinal monitoring for respiratory pathogens in broiler chickens reveals co-infection of Chlamydia psittaci and Ornithobacterium rhinotracheale.
Chlamydia psittaci is prevalent in broiler chicken production. However, the role of C. psittaci in the respiratory disease complex needs to be clarified. Our aim was to identify the time point when a C. psittaci infection appeared on a broiler farm and to examine the presence of other respiratory pathogens at that time. We focused on the 'major' respiratory pathogens occurring in Belgian broile...
متن کاملAntimicrobial susceptibility of Ornithobacterium rhinotracheale isolated from broiler chickens in Turkey
Minimum inhibitory concentrations (MICs) of eight antimicrobial agents were tested for 11 Ornithobacterium rhinotracheale isolates and for one type strain. Of the eight antibiotics examined, oxytetracycline was the most active antibiotic with MIC ranges of < or = 0.125 1 μg/ml for O. rhinotracheale isolates. All isolates were resistant to gentamicin and neomycin. Resistance to doxycycline occur...
