Effect of vaccination on Mycoplasma synoviae transmission in field conditions
A new study on the impact of vaccination in controlling the horizontal transmission of Mycoplasma synoviae in avian populations was published in Av. Path. The article titled "Quantification of the effect of vaccination on the control of horizontal transmission of Mycoplasma synoviae under field conditions" investigates the impact of vaccination on the transmission of Mycoplasma synoviae (MS) in poultry, particularly focusing on broiler and layer breeders. The study analyzes four years of monitoring data from both vaccinated and non-vaccinated flocks, assessing the incidence rates of MS and the effectiveness of vaccination in reducing horizontal transmission. The study confirms that MS vaccination significantly reduces the incidence of infection in poultry, with a marked decrease in cases observed after four to six successive vaccination cycles. Effective biosecurity measures are crucial in conjunction with vaccination to control the spread of MS. Farms with high biosecurity and single-age housing experience lower transmission rates. Implementing a vaccination program can lead to reduced economic losses associated with MS, making it a valuable strategy for poultry producers. The study advocates for a comprehensive approach that includes vaccination and biosecurity to effectively control Mycoplasma synoviae.
The study was performed in the Netherlands, and the vaccine in use was MS-H.
