A sample of (700) seven hundred out of (3000) three thousand randomly collected livers of sheep and cattle from Mosul abattoir during a biweekly visits of six months period , has been subjected to both grads and histopathological examinations.  Results indicated that parasites induced the highest percen tages of tissue changes in the livers of cattle and sheep, the parasites responsible were Hydatid Cysts and Fasciola gigantica which indicated that Mosul and surrounding areas were endemic with these parasites. Typical cases of liver cirrhosis were recognized in cattle and less in sheep. Mixed infection of mentioned parasites with liver abcesses and hepatic necrosis were diagnosed more frequ ently in sheep than in cattle, a diffuse form of lesbons was round in cattle while the focal from was encountered in sheep.  Congestion and degenerative changes like fatty livers were not seen in cattle but formed a respective percentage (1%) and (1.1%) in sheep. Other conditions were identified like icteric livers , than percentages were and low closely relatd in both species of animals.

Salmonellosis remains an important zoonotic disease and public health concern, Salmonella enterica serovar Albany is one of the motile serovars which has been identified from poultry and humans. However, its pathogenic potentials and shedding probability and duration from infected/colonized chickens have never been reported. To assess its pathogenic potentials and shedding probability 6 SPF BALB/c mice was inoculated with 0.1ml volume for each mice bacterial solution of 10 8 CFU/ml of Salmonella entrica serovar Albany after 24 hours the segments of the duodenum, jejunum, ileum, caecum and colon were fixed to study the histopathology and the polymerase chain reaction (PCR) was used to confirm the Salmonella entrica serovar Albany in the intestinal mucus swabs. The control group consist of 6 SPF BALB/c mice were inoculated with 0.1ml of 0.9% normal saline, The pathogenesis incidence rate of the disease caused by S. entrica serovar Albany revealed that prominent blood vessels on caecum 100%, red intestinal serosal 100%, infiltration of inflammatory cells in the crypt of liberkhun and submuscular layer of small intestine 100%, enterocyte necrosis 100%, haemorrhagic enteritis 83.3%, cecitis 33.3%, colonitis 66.6%, villus atrophy 100%, crypt atrophy 100%, and detachment of epithelial tissue 50%, can occur as soon as 24 hours post infection. Infected S. entrica serovar Albany was also successfully re-isolated from the intestinal swabs which revealed that the mice is potentially shed the bacteria through feces.
