S. ratti

S. ratti (Strongyloides ratti) is a parasitic roundworm that infects rats, mainly used in scientific research. It has a complex life cycle, including both free-living and parasitic forms, allowing it to reproduce either in the environment or inside a host. The parasite can cause gastrointestinal issues, and studying S. ratti helps scientists understand similar parasites affecting humans and animals. Because rats are commonly used in laboratory studies, S. ratti serves as a valuable model for researching parasitic infections, immune responses, and potential treatments.
