Thus, we have dual processes in the gerbil as well. However, little is known about the migratory behaviour or pathogenesis of ascarid larvae in gerbils. For recovering the parasite, the inoculation sites, livers and peritoneal cavities of the gerbils were examined at necropsy. Up to three 5 l injections were made in each gerbil retina with each injection placed at a different location. Foraging substrate and escape substrate: patch use by three species of gerbils. Histopathological sections revealed a larva in the optic nerve of the gerbil 6 days after inoculation (fig. 2). It is interesting, but not surprising, to learn that rodents like gerbils possess two visual systems. In the present study, some gerbils became weak and died due to cachexia with neurological symptoms and severe convulsion. Interestingly, no larvae were recovered from any organs of these gerbils beyond 14 days post-infection. However, no information is available on the migration route, the final site of infection, or on the pathogenesis of ascarid larvae in gerbils. In addition, calcareous corpuscles were abundant in the neck region and few small granules aggregated in the rostellum of the cysticerci from the gerbils. No granulomatous lesions were detected in any of the gerbils examined. Macroscopically, the gerbils exhibited fresh petechial haemorrhages of the lung 1 day after infection, but no new haemorrhagic lesions were evident beyond that time. This occurs when gerbils learn to scale the sizes of objects to allow them to jump long distances. These examples are from corpora and from sources on the web.
