The Mongolian jird (Meriones unguiculatus) is the preferred rodent model for large scale production of Brugia pahangi parasites. When the jird is inoculated intraperitoneally with B. pahangi L3, the parasites can reach adulthood and reproduce while remaining contained within the abdominal cavity. Although the jird is a highly successful model, it does present challenges in the form of cost and size and is a USDA regulated species. In this study we investigated the potential for an immune suppressed Sprague Dawley rat to serve as a production model for B. pahangi. We did this by assessing larval recovery rates in rats euthanized 14 days after inoculation with B. pahangi L3. We also performed differential cell cytologies of peritoneal fluid to determine what cell populations were present in infected animals vs naïve animals. Minimal larval recovery results indicate that the Sprague Dawley rat is not an ideal candidate for B. pahangi production.
