Out of 437 sheep inspected (1963 male and 2474 female), 242 (5.45%) sheep among 268 specimens collected from suspected cases of dermatophytosis, which had clinical lesions of dermatophytic infections, that confirmed by positive culture on (SDA+Chloramphenicol+Cycloheximide) supplemented with thiamine and yeast extract and /or by direct microscopic examination using 10% KOH solution. The ringworm infections were varied from summer months (June— October, 2005) to those of winter months (November.2005 to March,2006) which were 59 (3.06%) and 183 (7.29%) respectively . The fungus affect both, the .outer layers of the skin as well as wool. It was spread centrally outward causing more or less circular areas of wool loss leaving scaly to powdery skin which was gray-white in color, measuring 2-10 cm. in diameter. The head, ears, loin, and neck were the most areas had been affected. The only causative fungus isolated was Trichophyton verrucosum

In an experimental study was designed to evaluate the immunopathological effect of sensitized Mycobacterium bovis transfer factor in guinea pigs organs against challenge infection with these microorganisms. The results of this study were showed the followings: 1: Transfer factor recipient group:It was showed an early aggregations of macrophages and lymphocytes (early granuloma) in lungs and liver and reactive lymphoid hyperplasia and macrophages proliferation in the paracortical region of mediastinal lymph node and in periarteriolar sheath areas in the white pulps of the spleen (T cell regions).These early granulomas were persisted during 2" and 4h week postinocultation and slightly decreased and disappeared during the 6h and 8h weeks postinoculation respectively. 2:Group of infection with Mycobacterium bovis:It was showed on extensive tubercuclous granutomatous lesions in the lungs, liver, spleen, kidneys and in the mediastinal and hepatic lymph nodes.The lesions were initiated at 2nd week postinoculation and it gradually developed into extensive tuberculous granuloma with central caseation, during the 4h and 6h weeks postinoculation.These lesions were persisted and continued during 8h week postinoculation. Two animals died at 7h week postinoculation due to generalized tuberculosis. 3:Transfer factor recipient group and challenged with Mycobacterium bovis. It was showed a well developed granulomatous reactions in the lungs, liver, spleen and mediastinal and hepatic lymph nodes. These granulomas consisted of aggregation of epitheliod cells, lymphocytes and few giant cells without caseastion. These granulomas were initated during the 2' week and gradually increased in size in the 4h week and decreased at 6h week and completely disappeared during the 8th week postinoculation. No animals were died in this group. 4: Control group:It was showed neither morphological and nor histological lesions in the body organs.

Both macroscopic and microscopic results show the efficacy Show of Aloe vera oil extract in healing process as compared with control wounds.

This study was designed on to show the effect of albendazol and mebendazol alon and their combination on surviral , development and size of Echinococcus granulosus protoscolicies of (10 mg/ml) intraperitoneal in mice. The study show that the mebendazol and combination drugs were greater than the albendzol during on the first four days nor effect on the five day in vivo intraperitoneal administration of combination drugs were greater than albendazol and mebendazol alone on the development and size of cysts which about (5.2±2.17) , (7.0±1.0) , (10.0±3.16) for the development and (1.13±0.38) , (1.18±0.54) , (1.20±0.49) for the ysts size.

Antimicrobial disk susceptibility tests serve as standard assays for measuring the activity of compounds against pathogenic bacteria. In the current study, some plant-derived proprietary essential oil blends (Olea europaea , Pimpinella anisum L. , Coriandrum sativum , Matricaria chamomilla L. , Borago officinalis , Cimum basilicum L. , Cuminum cyminum , Thymus vulgaris thymol , Menta xpiperita L. , Rosmarinas officinalis comphora) were tested for their antibacterial activity against five common strains of pathogenic bacteria using disk susceptibility tests. A formulation intended for topical use (Essential Oil Formulation 1) (EOF1) inhibited the growth of Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus as evidenced by zone inhibition diameter measurements when compared to those reported for standard antibiotics. EOF 1 exhibited no activity against Proteus vulgaris and Staphylococcus epidermidis. The second formulation (Essential Oil Formulation 2) (EOF2), intended for inhalation use, inhibited the growth of all five test bacteria strains with zone inhibition diameters two to three times greater than those reported for standard antibiotics. The growth of all five bacteria strains was inhibited when a cotton swab impregnated with EOF 2 was suspended above the bacterial lawn, indicating a true vapor or fume effect by this formulation.

The twenty adult local male rabbits of mean body weight of 1 kgm and mean age of 6 months were randomly allocated into two groups of ten animals, each group was fed during the period of experiment on a standard diet . The first group was regarded as control and received 3ml of physiological saline orally for a month. The second group was drenched ethanolic extract of Taraxacum officinale (500 mg/kg/day) for one month . Those male were joined with females after treatment for a week to study the effect on fertility and reproductive efficiency. The following results were obtained: The ethanolic extract of Taraxacum officinale caused highly significant increase (p

The amount of four minerals (Magnesium, Calcium, Selenium and copper) and total protein of hydatid cysts fluid obtained from lung and liver of sheep and cow was checked. Magnesium (Mg+2) and calcium (Ca+2) showed higher levels in cysts of sheep than those of cow which was (8.38, 29.11, 7.90, 25.70 mmol/L) respectively whereas the selenium (Se+) and copper (Cu+) showed a little differences in both species. Total protein amonts were found to have wide range in both animal species.

The phenogenetic and phylogenetic relationships among 7 identified strains of C. pseudotuberculosis isolated from sheep were checked by PCR specific primers demonstrated with random amplified polymorphic DNA – polymerase chain reaction (RAPD – PCR) by using five arbitrarily primers. C pseudotuberculosis isolates were distinguished according to the banding patterns of their amplified DNA on agarose gel. The variation can be used for diagnostic differentiation among C. pseudotuberculosis strains. Differences were observed in RAPD patterns between the 7 isolates and this may be due to the presence of novel serovars of this microorganism.

A cross-sectional survey of ticks infesting sheep was conducted in Sennar State, Sudan. A total body collection of ticks was carried out at five localities Sennar town, Singa, Dinder, Abu Naama and Um Banein on two types of Desert sheep (Watish and Ashgar) on two farms at each locality at two monthly intervals for one year starting July 2002 to May 2003. Four tick genera and eight species were identified. They were Amblyomma lepidum, Hyalomma anatolicum anatolicum, Hyalomma truncatum, Rhipicephalus (Boophilus) decoloratus, Rhipicephalus camicasi, Rhipicephalus evertsi evertsi, Rhipicephalus guilhoni and Rhipicephalus muhsamae. A significant (P < 0.05) seasonal pattern of activity was observed for A. lepidum and R. guilhoni with peak activity occurring during rainy seasons. The highest mean number of ticks (7.26 + 0.58) was recorded at Abu Naama, while the lowest mean (3.61 + 0.31) was recorded in Sennar. Watish type sheep carried significantly (P < 0.05) more ticks than Ashgar type.

In the present study, polymerase chain reaction (PCR) using random primer (E-20) was used to characterize and identify strains included in this study. Strains included 4 vaccinal reference strains of Pasteurella multocida, CU strain and 4 field isolates of Pasteurella multocida isolated from diseased turkeys which were identified biochemically and serologically as A:1, A:3, A3x4 and D:11. The obtained results revealed that all strains were reacted positively and in different manner with the E20 primer except the 2 field isolates. The results of these reactions demonstrated in terms of bands of different molecular weight specific to each strain. This can be used as a base for characterization and differentiation of strains involved in the present study as the 2 field strains A:1 and A:3 react with primer. Mouse protection test was performed by vaccination of mice with local fowl cholera oil adjuvant vaccine then challenge with virulent field strains A:1, A:3, D:12 and untypable isolates. Results revealed that the local fowl cholera adjuvant vaccine could protect mice against virulent challenge with A:1, A:3 and D:12 field strains but it could not be protect mice against untypable isolates
