Description of Haematology and Histopathology of Duck Digestive System With UV Light Irradiated Salmonella sp

Abstract

Salmonella sp is a cause of Salmonellosis in ducks. One way to kill these bacteria is to use ultraviolet (UV) light. In this study irradiation for 15, 25 and 35 minutes. Salmonella sp bacteria can attack several physiological systems of the body, one of which is the digestive system. This is because bacteria infect ducks through food and drink that has been contaminated with bacteria. To see the effect of Salmonellosis, a blood sample and organ of the ducks were removed every 2 weeks from the treatment. The physiological condition of ducks infected with Salmonella sp can be seen in hematological conditions and histopathological picture of the liver and intestines in ducks that have been infected with Salmonella sp bacteria that have been exposed to ultraviolet. Based on the results of research that has been done, it was found that the illumination of Salmonella sp using UV light for 35 minutes was most effective to weaken the bacteria because the results showed the smallest value compared to other controls and irradiation. Some histological abnormalities were found in the liver and intestines but still in a condition of minor damage because the damage was only found a little. Abnormalities that occur in the liver include bleeding, nucleus picnosis, necrosis and inflammation, while in the intestine found abnormalities include desquamation of epithelial cells, bleeding and proliferation of goblet cells.
