[The frequency of detection of Mycoplasma meleagridis in breeding turkeys depending on the laying age].
Coating of air sacs was recorded from day-old chicks from parents with Mycoplasma (M.) meleagridis infection, with positive findings being obtained from 9.52% of all animals early in the laying period and from 34.09% up to the 8th laying week. M. meleagridis was isolated from palatine and cloacal swabs taken of laying hens and insemination cocks, with positive findings being 50-60% prior to the laying period (28th week of age), 100% at start of laying, and 80% in the 14th laying week. M. meleagridis was identified in 50% of all embryonated eggs as of the 1st laying week and in 100% as of the 4th week. M. meleagridis was cultured from 30.67% of all sperm samples tested, between the 30th and 46th week of production. Differences were found to exist between individual cocks, with 4 cocks being without M. meleagridis at all. There was usually agreement between positive M. meleagridis findings from sperm and cloacal swabs. M. meleagridis was eliminated from cock sperm by spectinomycin (0.6 mg/ml diluting medium), but M. iowae was not.
