Aim: This study was designed to study the gastrointestinal helminths in Rattus norvegicus to assess the relevance of rats as the carrier of zoonotic parasites for public health.
Material and Methods: A study of the effects of helminth parasites on rats’ gastrointestinal tract was conducted with the help of Randox kits. Rattus norvegicus used in the study were trapped from different locations in Pakistan and then maintained and raised in live traps under natural temperature. The rats received a daily ration of barley and water. Gastrointestinal tract organs were separated from the body cavity of dissected rats (intestine, stomach, pancreas, liver, lungs, and rectum). Thereafter, total protein & lipase determination was carried out from these organs.
Results: The activity of the total protein in the intestine, stomach, and lungs was increased in infected Rattus norvegicus as compared to the non-infected, while the activity of the total protein in the pancreas, liver, and rectum was found significantly decreased in infected rats as compared to non-infected rats. The activity of lipase in the intestine, stomach, pancreas, and lungs in infected Rattus norvegicus was higher as compared to the non-infected. While the activity of lipase in the liver and rectum was found lower in infected rats as compared to the non-infected rats.
Conclusion: It was observed that helminth infection increased the activity of lipase in the intestine, stomach, pancreas, and lungs; while the decreased activity of lipase was observed in the liver and rectum.
