The current study was conducted from October 2013 until the beginning ofSeptember 2014 to estimate the Omega -3fatty acid for three species of marine fish(Acanthopagrusarabicus , Chelonsubviridis and Cynoglossusarels). The study wasconducted during the four seasons winter of 2013, spring of 2014 , summer of 2014and fall of 2014. The oil was extracted by organic solvent extraction, the fatty acidwas estimated using Gas Chromatography connected with mass spectrometry(calculated on the basis of the total amount of the fatty acids), omega–3 percentage ofboth types DHA, EPA has varied between the fish as it reached 56.5% , 55.9% ,67,13% , 49.22% during winter, spring, summer and autumn respectively. Also it wasfound ,by the results, that the percentage of omega -3 type EPA was high in the winteras the percentage was 30.99%, followed by the summer as it was 30.42% and thelowest rate was in the autumn as it was 20.33%, while the percentage of the secondtype of omega -3 DHA was close during the four seasons, as the summer achieved thehighest percentage which was 36.71% and the lowest percentage was in the winter asit reached 25.06%.

The present work is designed to anatomical, histological and histochemical studyof the proventriculus of common moorhen (Gallinula chloropus). Thirty adultcommon moorhen which obtained from a commercial market of (Al Basra city) wereused in this study, and the work conducted at veterinary medicine collage –universityof Basra. The anatomical study revealed that the proventriculus of common moorhenwas tubular in shape with average mean of its length and width (20.00±.7906mm),(10.48±.1.53194mm) respectively. The internal surface of the proventriculuswas smooth and raising no papilla. The proventriculus connect with esophaguscranially and with muscular stomach caudally, It lies essentially in the vertical plane.The histological study showed that the proventriculus of common moorhen consist offour tunics (mucosa, submucosa, muscularis externa and serosa).The mucosal layer ofcharacterized by branched longitudinal folds (villi) lined by simple columnarepithelium, the sub mucosal layers manifested by presence of compound tubularglands which was arranged in pyramidal or conical shape (adenomere), whilemuscularis externa consist of two layers longitudinal inner and outer layer wascircular. The tunica serosa composed of loose connective tissue covered bymesothelum. The statistic analysis revealed that the average lengths of villi andadenomere were (74.50 ±14.72mm), ( 107.63±45.81mm) respectively, while theaverage width of villi, tunica sub mucosa, adenomere, muscularis externa and serosawere (8.75±2.36 mm), (143.12±30.37mm), (85.62±54.76mm), (22.12±6.29mm),(2.50±.00mm) respectively. The histochemical study of proventriculus showed thatthe carbohydrate have positive reaction with shiff reagent in the surface epithelium sub mucosal glands, tunica muscularis and serosa. While the glycogen granulesdistributed in the epithelium, around the sub mucosal glands and in tunica muscularis

Eight Samples of tumor masses were collected from cases of (3)squamous cellcarcinoma in vulva (SCC) and(5) ruminalfibropapillama in cows fromBasraprovincesouth of Iraq during the period February 2013 through January 2014 . The cases of SCCcases were characterized by smooth, dry, white poorly demarcated dermal bundles ofhomogenous tissue with necrotic or\and hemorrhagic foci separated by fibrous tissue intheearlyand late stage named as acanthosis . The size offibropapilloma cases werevariable in size and characterized byabundant proliferating fibrous tissue massgrowth inthe rumen covered by stratified squamous epithelium of varying thickness exhibitingmarked hyperkeratosis of the stratumcorneum of rumen.

Eperythrozoonosis is a small ruminant disease caused by the bacterium Mycoplasma ovis (formerly known as Eperythrozoon ovis). Whilst acute infection in sheep may result in an anaemia and ill thrift syndrome, most animals do not develop clinical signs. Molecular methods were used to compare and evaluate the prevalence of infection with M. ovis in sheep and goats in Tunisia. A total of 739 whole blood samples from 573 sheep and 166 goats were tested for the M. ovis 16S rRNA gene using PCR. The overall prevalence was 6.28% ± 0.019 (36/573). Only sheep were infected with M. ovis (p < 0.001), and the prevalence was significantly higher in central Tunisia (29.2%) compared with other regions (p < 0.05). The prevalence revealed significant differences according to breed and bioclimatic zones (p < 0.001). Furthermore, the prevalence in young sheep (35/330; 10.6%) was higher than in adults (1/243; 0.41%) (p < 0.001). Only sheep of the Barbarine breed were infected, with a prevalence of 11.8% (p < 0.001). This is the first molecular study and genetic characterisation of M. ovis in North African sheep breeds.

The aim of the present study was morphological and histochemical analysis of the lacrimalgland (LG) in African black ostrich Struthio camelus domesticus in the embryonic and postnatalperiod. Studies were conducted on 50 ostriches aged between the 28th day of incubation until7 months old. Tissue sections were stained with haematoxylin and eosin, Azan trichrome,periodic acid-Schiff, Alcian blue pH 2.5, aldehyde fuchsin and Hale’s dialysed iron. The LGin ostrich was classified as a tubulo-acinar type. The primordia of the lobes were determinedin the LG structure on the 28th day of incubation, whilst the weakly visible lobes with aciniand tubules were observed on the 40th day of incubation. Morphometric studies of the LGshowed steady growth, characterised by an increase in both length and width. Histometricmeasurements of lobe size showed little difference between the first, second and third agegroups, whilst in the fourth age group a marked increase in size of lobes was observed.The study showed that, apart from morphological changes, during the growth of the LGthe character of acid mucopolysaccharides changed. Sulphated acid mucopolysaccharideswere indicated, particularly with aldehyde fuchsin (AF) staining in the fourth age group.The Hale’s dialysed iron (HDI) staining showed a low concentration of carboxylated acidmucopolysaccharides in the first and second age groups and a higher concentration in thethird and fourth age groups. Periodic acid-Schiff staining (PAS)-positive cells were observedin each age group, but only a small number of cells with a weakly PAS-positive reaction weredemonstrated in the first age group.
