One hundred fifteen samples of the urinary bladder were collected randomly from slaughtered local bovine calves in Mosul city during March 2018. Gross and histopathological changes revealed in 37 samples 23.1%. Gross changes represented by congestions, petechial hemorrhage, inflammation and cystic hernia. Histopathological changes included the disturbances of cell metabolism represented by cell swelling of transitional epithelial cells and smooth muscle cell 16.2%, and coagulative necrosis of epithelium of mucosa and Zenker's necrosis of muscular layer 40.5%. cell adaptation manifested by epithelial hyperplasia 18.9% and smooth muscle fibers atrophy 8.1%. Circulatory disturbances represented by hyperemia and congestion 51.3%, petechial hemorrhage, edema and thrombi 5.4% for each. Acute cystitis showed in percentage of 18.9% while chronic cystitis was 13% and fibrosis 21.6%. Congenital deformities represented by cystic hernia 13% and bladder wall intrusion 5.4%. This study concludes the presence of different types of pathological changes in the urinary bladder of slaughtered local bovine calves in Mosul city which indicates presenting different types of causative agents and infections.

The objective of current study was to determine the prevalence of bovine heamotropic mycoplasma in cattle using conventional polymerase chain reaction (PCR) in Nineveh province/ Iraq, to investigate some of the epidemiological risk factors associated with occurrence of the disease. From September 2017 - September 2018, four hundred blood samples were obtained from cattle both sexes, different ages, origin, different management systems and from different regions in Nineveh province, ten milliliter blood were collected from the jugular vein for PCR test, whatever epidemiological data were collected through interview with the farms owners. The results of this study appear that the prevalence of bovine heamotropic mycoplasma was 75%. The risk factors associated with increased prevalence of disease include age, increased prevalence was at >3 years, females, imported animals, indoor animals which were 86.8, 80, 91.7, 77.5% respectively. The significantly increased prevalence of the disease 93.7% in the western regions of Nineveh province. In spring and summer months a significantly increased prevalence of disease which were 79.6 and 78.95 respectively. In conclusions, this study detected that bovine heamotropic mycoplasma was widely distributed in Nineveh province associated with several risk factors.

Fasciolosis cause economic losses in cattle that breed in Iraq and the world. About 4% of bovine liver’s samples included in the current study exhibited classical pathological lesions of fasciolosis. Samples of cattle livers infected with fasciolosis were taken for histopathology. Eighteen grading criteria with four scoring level have been chosen to grading the microscopic lesions caused by Fasciola hepatica into a mild infection (grade I), moderate infection (grade II) and severe infection (grade III). The type of hepatic degeneration or necrosis, cloudy cell swelling, coagulative necrosis, infiltration of inflammatory cells, with patterns of infiltration, also type of infiltrated cells, fibrosis between hepatic cells or in portal area, affection to hepatic cords arrangement, hepatic sinusoids, extensions of hemorrhage, pigment deposition, hyperplasia of bile duct, thickness of hepatic capsule and presence of liver fluke were the main grading levels. In grade, I the microscopic lesions were characterized by simple or mild in their nature with very good reversible prognosis, while grade II characterized by moderate severity of the lesions with a good reversible prognosis, while grade III characterized by hostile severity with bad irreversible prognosis as a result of architecture changes in liver histology. In conclusion, we believed that this grading system could be used as a guide when examining histopathological liver's samples infected with F. hepatica to identify the stage of infection and proposed an accurate prognosis.

This study was done for the detection of capsulated Staphylococcus aureus strains which were isolated from bovine & buffaloes Mastitis. 23 (57.5 %) & 8 (53 %) strains of these bacteria were isolated, 6 (26 %) & 2 (13.3 %) were capsule producing strains, and that 9 (39.1 %) & 4 (26.6 %) were slime producing strains, respectively. An increase in the number of capsules and slim producing strains was observed following growing of these bacteria in culture media containing glucose and milk. The experimentally performed histo-pathological study, revealed presence of capsules in lung sections stained with Hematoxylin–Eosin as a halo areas appeared around the bacterial cells. In addition to a strong positive reaction with periodic acid shiffs.
