Trichinella Nativa

The effects of infection by two species of sylvatic Trichinella on the diel locomotory activity of a wild rodent host, the deer mouse Peromyscus maniculatus, in a familiar environment were investigated in the laboratory using computer-linked activity chambers equipped with an infrared photocell. Locomotory activity data were collected on each mouse prior to and after sham inoculation or inoculation with graded doses of muscle-encapsulating Trichinella nativa or nonencapsulating Trichinella pseudospiralis larvae. Trichinella nativa infections induced activity deficits in deer mice that were proportional to the number of infective larvae recovered, whereas derived indices of locomotory activity of mice infected with T. pseudospiralis remained essentially within the range of those of sham-inoculated control mice. Quantitative differences between T. nativa and T. pseudospiralis in their potential to modulate the host's immune response may account for the observed difference in their effect on locomotory activity of the deer mouse host. Such variation in trichina-induced changes in diel locomotory activity may serve to channel transmission of the parasites to suitable hosts.

In North America, Sin Nombre virus (SNV) is the main cause of hantavirus cardiopulmonary syndrome (HCPS), a severe respiratory disease with a fatality rate of 35–40%. SNV is a zoonotic pathogen carried by deer mice (Peromyscus maniculatus), and few studies have been performed examining its transmission in deer mouse populations. Studying SNV and other hantaviruses can be difficult due to the need to propagate the virus in vivo for subsequent experiments. We show that when compared with standard intramuscular infection, the intraperitoneal infection of deer mice can be as effective in producing SNV stocks with a high viral RNA copy number, and this method of infection provides a more reproducible infection model. Furthermore, the age and sex of the infected deer mice have little effect on viral replication and shedding. We also describe a reliable model of direct experimental SNV transmission. We examined the transmission of SNV between deer mice and found that direct contact between deer mice is the main driver of SNV transmission rather than exposure to contaminated excreta/secreta, which is thought to be the main driver of transmission of the virus to humans. Furthermore, increases in heat shock responses or testosterone levels in SNV-infected deer mice do not increase the replication, shedding, or rate of transmission. Here, we have demonstrated a model for the transmission of SNV between deer mice, the natural rodent reservoir for the virus. The use of this model will have important implications for further examining SNV transmission and in developing strategies for the prevention of SNV infection in deer mouse populations.
