Recently, mechanism study of hepatitis E virus (HEV) infection has attracted an increasing attention because of the growing rate of the acute hepatitis caused by the virus over the world. As an important initiate in the inflammation, mast cells (MCs) play a critical role in maintaining a healthy physiology. However, the function of the MCs in the acute hepatitis caused by HEV is still unclear. In the present study, mongolian gerbils infected by HEV were used as an animal model to evaluate the role of MCs in the HEV infection. The positive ELISA and RT-PCR results showed the gerbils was successfully infected with HEV. The number of mast cell in the liver and the small intestine in the infected animals were growing higher significantly than the control group. In addition, higher expression of the tryptase and 5-HT in the liver and the intestine detected by immunohistochemical method and western blot also indicate the activation of MCs in the infection. These results suggest that MCs play an important role in the hepatitis E.

Hepatitis E Virus (HEV) is a globally widespread pathogen that causes acute hepatitis infection. Beyond hepatic pathogenesis, HEV has been proven to cause several extrahepatic manifestations, such as neurological, renal, and hematological manifestations. It was also associated with mortality in pregnant females.

Historically considered to be nonenveloped, hepatitis E virus (HEV), an important zoonotic pathogen, has recently been discovered to egress from infected cells as quasi-enveloped virions. These quasi-enveloped virions circulating in the blood are resistant to neutralizing antibodies, thereby facilitating the stealthy spread of infection. Despite abundant evidence of the essential role of the HEV-encoded ORF3 protein in quasi-enveloped virus formation, the underlying mechanism remains unclear.

This study explores potential small animal models for the dog hookworm, , a parasitic nematode which has repeatedly exhibited the ability to develop resistance to a range of anthelmintics. Immunomodulated hamsters, gerbils, rats, and mice were infected with Despite varying degrees of immunosuppression, and in some cases, total adaptive immunodeficiency, no adult worms were recovered, and larval arrest (L3 stage) occurred in muscle tissue of mice and hamsters. This highlights the strict host specificity of and emphasizes the challenges of developing rodent models usable for anthelmintic testing with a strict specialist parasite.

Giardiasis, caused by Giardia duodenalis, is a prevalent and significant zoonotic disease. While nitroimidazole drugs are primarily used to treat giardiasis, the urgent need for the development and formulation of new drugs has arisen due to increasing drug resistance. Several plant derived medicine have been employed as antiparasitic drugs.
