Chandra, V.; Taneja, S.; Kalia, M.; Jameel, S. Molecular biology and pathogenesis of hepatitis E virus. Overall, while there are many similarities between these two groups of animals, they are distinct in a number of important ways. Under experimental conditions, as mentioned above, pigs affected with swine HEV demonstrated no clinical defects but were consistently able to reproduce microscopic liver lesions that were similar to the naturally infected pigs with measurable HEV RNA in the feces, liver tissues, and bile [, Overall, as a model for human HEV infections, swine proficiently yield infection with gt3 and gt4 HEV and serve as a major reservoir for foodborne zoonotic HEV spread to humans. Evidence of the Extrahepatic Replication of Hepatitis E virus in Human Endometrial Stromal cells. Meng, X.J.

Although convincing results from previous studies have proved rabbits to be one of the best models to utilize for HEV pregnancy mortality at the current time, there are specific drawbacks to the model. All rodents have one thing in common, they have specialized teeth for gnawing. Both rabbits and rodents each have two lower incisors. Through these, the interactions between seeds and small rodents or lagomorphs are not exclusively positive (seed dispersal) or negative (seed predation), but located at some point along a mutualismantagonism continuum, which makes food-hoarding animals conditional mutualists (Theimer, 2005, Gmez et al., 2019). Rabbits have a systemic infection resulting in liver lesions as well as the ability of the virus to progress to chronicity and to cause pregnancy mortality (, Cynomolgus monkeys have a haemomonochorial and bidiscoid type of placenta that is very similar to the human placenta [, After the successful experimental infection in cynomolgus macaques, other NHPs were evaluated for the study of HEV. At 49 dpi, two of four ovary samples in the HEV-infected groups demonstrated both positive-stranded and negative-stranded HEV RNA. ; Moskal, T.; Purcell, R.H. Infectivity titration of a prototype strain of hepatitis E virus in cynomolgus monkeys. However, they only have one pair of incisors, compared to the two pairs that lagomorphs have.

In addition, they eat differently from rodents, as they can barely use their front limbs to hold food. Human pregnancy is divided into three trimesters, each lasting approximately 90 days. At 20 dpi, human HEV-inoculated pigs demonstrated hepatic inflammation and hepatocellular necrosis, which peaked in severity, and at 55 dpi, they were found to be moderately severe. While there are many differences between rabbits and rodents, there are also some similarities. Phylogenetic trees based on probability analysis of orthologous proteins (Graur et al., 1996) and nuclear genes (Misawa and Janke, 2003) demonstrate that lagomorphs may be more closely related to humans than to rodents, suggesting that at least some of the morphological similarities between lagomorphs and rodents may have Rabbits are different from rodents in several ways.

Comparative aspects of trophoblast development and placentation. Liver tissue histopathology in pregnant rabbits with HEV infection was also conducted and demonstrated bridging necrosis or piecemeal necrosis and the infiltration of inflammatory cells via hematoxylin and eosin (HE) staining. Inflammatory exudates and hemorrhages were apparent upon histopathological examination, suggesting that severe inflammatory responses were seen in the uterus of terminated mice (middle pregnancy).

Costa, M.A. An ideal animal model, which reliably reproduces all aspects of pregnancy mortality and pathology, associated with human HEV infection during pregnancy, does not currently exist, and finding an amenable system reaching all ideal requirements might not be feasible. Experiments that compare and contrast the tried-and-true natural HEV infection models, such as swine and non-human primates, which fail to induce enhanced pregnancy mortality, and the rabbit model in which pregnancy mortality was observed might be a key piece to understanding important differences in the virus and host responses leading to HEV pregnancy mortality. Our mission at Pet Keen is to make the life of you and your pets easier and even more enjoyable. ; Fichorova, R.N.
