Prevalence of etiological agents of selected respiratory infections in chicken and turkey farms in the Czech Republic

Abstract

The causative agents of respiratory diseases of turkeys represent, primarily in fattening farms, a substantial risk of economic and breeding problems. The purpose of this communication is to provide information on the prevalence of respiratory agents of turkeys and chickens in several fattening and production farms in Southern Moravia. This study was focused on pathogens causing bacterial diseases such as Ornithobacteriosis and Mycoplasmosis, as well as viral rhinotracheitis and laryngotracheitis of poultry. The laboratory diagnosis of these diseases has been performed in our institute since January 2008. We examined 249 samples of turkeys and chickens from a single rearing house and six fattening farms in Southern Moravia. The samples were examined using the PCR or RT-PCR method. The typing of isolates of Ornithobacterium rhinotracheale was done using the M13 fingerprinting method. We established the prevalence of pathogens such as Ornithobacterium rhinotracheale (ORT), Mycoplasma gallisepticum (MG), Mycoplasma synoviae (MS), avian metapneumovirus (aMPV) and laryngotracheitis virus (ILT) in selected farms.
