| Abstract | ||||
| Poultry industry is faced during the last years by pro- blems resulting from respiratory infections. Mycoplas- mas are reported by several authors to cause consider- able economic losses (Cahalam,1974). Stipkovits (1979) pointed out that layers infected with mycoplasmas produce lesser eggs and also showed reduc- tion in the rate of hatchability by 10-15 4%. It. is known that avian mycoplasmas nowadays include 19 species, however only 4 species, namely M. gallisepti- cum, M. synoviae, M. meleagridis and M. iowae are rep- orted to be pathogenic (Yamamoto, 1985). It is however not known which species are prevalent among poultry in the kingdom, therefore the aim of the present work was to elucidate the incidence of myco- plasmas in poultry in various different farms in the kingdom. MATERIAL AND METHODS Chickens of different ages (less than one month and up to 10 months) were collected from 7 farms in the Eas- tern Province. A total of 457 samples of the internal Organs, namely, the lungs, trachea, air sacs, liver, Spleen, kidneys, heart, gizzard, caecum cloaca, ovar- ia, testes and joints of 95 chickens, were collected aseptically and inoculated into broth and on solid. | ||||
