Characterization of a Naturally Occurring Infection of a Mycoplasma gallisepticum House Finch-like Strain in Turkey Breeders

摘要: Abstract An outbreak of Mycoplasma gallisepticum (MG) in commercial turkeys involving very mild clinical signs was difficult to confirm by routine methods. In the first part this study (trial A), we conducted a bioassay increase likelihood detecting MG. Susceptible were inoculated with sinus exudates from four different affected turkey flocks. Turkeys evaluated for signs, as well serology and culture tracheal swabs, at 21 42 days postchallenge. MG isolate one used inoculation, designated K5054, similar isolates house finches when characterized random amplified polymorphic DNA analysis sequence portions phase-variable putative adhesin protein (pvpA) gene, lipoprotein cytadhesin gapA/mgc1 gene. The K5054 exudate seroconverted absence severe signs. There single reisolation the...
