Abstract
This study investigated effects of aqueous and ethanolic clove extracts in small intestine and liver of chickens exposed to Salmonella typhimurium. Two hundred fifty-day-old chicks were divided into five groups. Group 1 served as the control and received a basic diet.Group 2 was orally infected with Salmonella typhimurium. Group 3 received same infection but was treated with Ciprofloxacin. Groups 4 and 5 were infected but received treatments of aqueous and ethanolic clove extracts, respectively. The findings revealed that Group 1 exhibited normal small intestine, while Group 2 displayed severe abnormalities, including flattened mucosa, damaged villi, and inflammation. Group 3 showed improvements, increased cell growth and goblet cells in the small intestine. Group 4 displayed nearly normal intestinal features. Group 5 had fully restored intestinal health. In the liver, Group 1 showed typical hepatic structure, whereas Group 2 exhibited signs of inflammation and hepatocyte necrosis. Group 3 displayed severe hepatocyte damage, while Group 4 demonstrated restored liver structure with slight sinusoidal dilation. Group 5 had a well-preserved hepatic architecture with minor inflammation. Administration of 2 mg/kg of aqueous and ethanolic clove extracts demonstrated alleviate histological alterations in small intestine and liver caused by Salmonella typhimurium infection. Notably, the aqueous extract is more effective than ethanolic extract in reducing liver and intestine damage.
