Trichosomoides nasalis is a parasitic roundworm thatattacks mice .
Life cycle
The nematode larvae develop in the skeletal muscles . Unlike with trichinae , there is no developmental standstill in the first larval stage, but further development into adults within three weeks. Females and dwarf males migrate from the abdomen and thorax into the nasal region and here in the layer between connective tissue and muscles, some also in the blood vessels of the nasal mucosa . In the lamina propria mucosae the sexes are still separated. Females found in the epithelium of the nasal mucosa, on the other hand, already contain intrauterine dwarf males. In the infected host, the nasal mucosa becomes inflamed .
