This study comprised the examination of seven hundred and
eighteen samples that were collected from farms and backyard of ducks
in Dakahlia and Sharkia Govemorates to detect the incidence of natural
infection of ducks with Mycoplasma. The isolates were identified by
phenotypic and genotypic. Mycoplasma gallisepticum (MG) was
isolated from (76.92%) of examined lungs, (33.33%) of egg yolk and
(25%) of trachea. Also M. gallinarum was isolated from (75%) of
trachea, (36.36%) of tracheal swabs. While, M. anatis was isolated from
(66.67% and 23.08%) of egg yolk and lungs, respectively. Acholeplasma
species could be isolated only from (63.64%) of tracheal swabs.
-Biochemical characterization and serological identification proved
that the three Mycoplasma species could be identified as M. gallinarum,
M. gallisepticum and M. anatis. The highest recovery rate of
M. gallinarum was (75%) from trachea, followed by tracheal swabs
(36.36%). M. gallisepticum, the isolation rate was high from lungs
(76.92%), followed by egg yolk (33.33%) and trachea (25%). On the
other hand, M. anatis could be isolated from egg yolk and lungs (66.67%
and 23.08%, respectively).
Acholeplasma species could be isolated only from tracheal swabs
(63.64%).
On the other hand, SPA results revealed that three egg samples out
of one hundred and twenty were positive for M. anatis and
M. gallisepticum antibodies two isolates related to M. anatis with an
incidence rate (66.67%) while one isolates related to M. gallisepticum
with an incidence rate (33.33%).
