Serological Investigation of Chlamydophila abortus on Abortive Cows in Middle Area in Syria

The aim of this study was to investigate the specific antibodies and to determine the seroprevalence of Chlamydophila abortus on abortive cows in north area in Syria. Blood samples were collected and analyzed from 41 cows, aborted at least once, taken from 316 cows suspected from eight herds in north region of Syria.

A Study of the Problem of Self-Incompatibility in the "Khodeiri" Variety and Some Pollinated Olive Varieties

The self-incompatibility problem appeared in the Khodeiry variety widely grown In Lattakia. When this phenomenon was studied on the Khodeiry variety in two areas (Jabla and Boqa), the results showed that this variety is self-sterile, i.e. it is not able to pollinate itself or the flowers of other trees of the same variety, and its fruit is very small and do not contain seeds. The results also showed that the flower abortion percentage in the Khodeiry variety is due to the genetic factor which varies depending on the variety. The study investigated the self-compatibility in some olive varieties in order to use them as pollinizers for the Khodeiry variety with the result that the Gellet, Soufrawy and Sourany varieties are particularly compatible and have a high compatibility with the Khodeiry variety. Based on these results, it is recommended that pollinated varieties are grown between olive orchards to improve fruit and to increase its production.

Bacterial Isolation and Molecular Characterization of Brucella Melitensis that Causes Caprine Abortion in the Middle Region of Syria and Differentiation between Field and Vaccinal Strains Isolated in this Study

The aim of this study is isolating brucella and using polymerase chain reaction technique for the molecular characterization of Brucellamelitensis,which causes caprine abortion. It also aimsto determine the rate of caprine abortion that is caused by Brucellamelitensisin the Middle region of Syria. For this purpose 58 abortion samples were collected (36 aborted fetuses, 22 vaginal swabs). The results of bacterial isolation and polymerase chain reaction reveal that the prevalence of caprine abortion caused by Brucella melitensis was 53.4%. The study also reveals that using stomach contents from caprine aborted fetus can be the best site for brucella isolation. Running differentiation tests to distinguish field strains from vaccinal strains refer to the presence of 2 isolates(6.4%) belonging to vaccinal strains(Rev1) from 31 isolates of Brucella melitensis.
