Collectively 146 milk samples from 73 ewes were taken for the California mastitis test( CMT), bacterial culture and antibiotic susceptibility of isolates. Samples from both glands of 37.73 (50.68℅) ewes had positive CMT results. Bacteria were isolated from 30.146(20.54℅) udder halves and 17.73(23.38℅) ewes. Prevalence rate of subclinical mastitis based on positive CMT and bacteriological results was 23.28℅ of examined ewes. A total of 30 isolates comprising escherichia coli 33.33℅ , staphylococcus aureus (16.66℅), staph. Epidermidis (16.66℅), staph. Intermedius(16.66℅) and streptococcus agalactiae (16.66℅) were identified. Antibiotic sensitivity testing revealed gentamicin to be the most effective antibiotic against all the of isolates, with 28.30(93.33℅) being susceptible. A positive correlation was found between CMT score and the age of ewe( p<0.01). The relationship between CMT score and the bacterial isolation rate was not statistically significant( p>0.05). It is concluded that for screening of subclinical mastitis in Ghezel sheep flicks, CMT test could be used with 100℅ sensitivity. Manuscript profile -

Radiography survey did not show a metastatic mass in thoracic cavity. The patient was prepared for operation and positioned in venteral recumbency . After surgical excision the incision was sutured routinely . Excised sample fixed in 10℅ formalin and then embedded with paraffin. Macroscopically , tumors has been appeared as yellow to flesh- colored papules, and microscopically , basophilic reserve cells with fewer sebocytes and ducts were seen. This clinical report showed that sebaceous epitheliuma could develop on other place like on back in poodle dog. Manuscript profile -

Form years ago herbal medicines had used for treatment of parasitic diseases. Later they has replaced by new chemical medicines, but these drug such as benzimidazole and analyzed groups created resistance, therefore praziquantel forte as new medicines has used. In this study ,in 30 dog of different gender ,race and age, the anthelminth,s effect of this drug has studied. Before treatment and 48 hours after oral medicine, stool samples were taken and RPG( Eggs per gram) were measured. Results of this study has showed that maximum of EPG before treatment was 73℅ and after was reduced to 4℅. Minimum of EPG before treatment was 5℅ and after was 0℅. Finally by statistical soft ware the average of all percentages of cleaning was 90.91℅. Manuscript profile -

A hemispherical mass, 18 mm in maximum diameter, without a peduncle and bright reddish in color, was observed on the gingive of the left mandible. Radiographic study shows osteolysis. The tumor was surgically removed via gingival incision around the margin to the depth of connective tissue layer. Histopathological examination indicated that the tumor contained a large number of neoplastic fibroblasts intermixed with vascular stroma and collagen tissue and was diagnosed as fibrornatous epulides with malignant characteristics. Tumor was recurred after 3 months. Due to lack of owner interest to treatment with chemotherapy agents and following his decision, the cat was euthanized with overdose injection of thiopental sodium.
