[Control of mycoplasmosis via poultry eggs and sperm by using tylosin].

A review is made on the existing references concerning the utilization of tilosin and some other antibiotics for limiting the distribution of or complitely eliminating mycoplasmosis in poultry and turkeys. Opportunities are discussed for preventing the emission of mycoplasmae with the eggs and spermal liquid of the diseased birds (treatment of the egg layer or of the sperm), as well as methods for elimination of the infection on the eggs (pre-incubation heating, dipping in antibiotic solutions or injection of various antibiotics). Most effective proved to be the methods of tilosin injection in the air camera of the eggs (1--3 mg/egg between the 7th and the 11th day from the beginning of incubation) and pre-incubation dipping of the eggs in tilosin solutions of 1000--3000 ppm concentrations. Cheaper and more suitable for practical use is the first method. Precise recommendations are given for obtaining PPLO-free bird flocks.
