This work was conducted at Jidreen Awassi sheep Research Station during 2002-2004, aimed to investigate pneumonia and its causes.

Pneumonia is considered to be one of the most important sheep diseases, especially in lambs.

It causes sickness followed by death resulting in big economic losses.

This research aimed to limit the losses as much as possible through the discovery of the most important bacterial and fungal causes which lead to Pneumonia, by means of laboratory tests for treating it and determining the best efficient and specific anti-biotic repellents.

The herd of Awassi sheep at Jidreen research station kept for recording the pneumonia cases reached 717 heads during 2002- 2004 research period.

The ages ranged between 1 month to 6 years, and there were 60 heads clinically suffering normally from acute and chronic Pneumonia.

In addition 140 specimens were collected (60 nasal swabs+ 60 blood specimens+ 20 pieces taken from dead or slaughtered sheep lungs).

This was arranged for the purpose of lab, microscopic test, bacterial and fungal culture and testing plate agglutination sensitivity.

These tests were conducted at Afico pharmaceutical industries lab located in the city of Hama.

As a result of this research, 94 microorganisms were isolated; which were the main causes of Pneumonia of whom the most important were pasteurella (4 0%), staphylococcus pyogenes (3 5%), E.coli (5%) and klebsiella Pneumonia(5%),either in pure or in mixed culture.

Mycoplasma in blood was also detected (23.3%) as a result of the fast agglutination test using special antigen.

Enroflaxacin, oxcytetracycllin and gentimicine products showed high efficiency against most isolated bacterial microorganisms.

Results showed through this research that the isolation of factors which cause sheep Pneumonia, in addition to the discovery of the effective antibiotic repellent to be used in pharmacological treatment, played a great role in detecting the infected sheep, especially when they were applied at the early stages of disease.

Consequently, this will reduce the losses due to high rate of infection with the disease and also the death cases among Awassi sheep herd, particularly in lambs undergoing intensive breeding.
