Snake strongyloidiasis was studied in specimens of Liophis miliaris that were experimentally andnaturally infected with Strongyloides ophidiae. Fecal analysis indicated that S. ophidiae parasitism could last more than three months in the host. Parasite development occurred in snakes infected via the subcutaneous route, and the prepatent period of the infection was seven days. These snakes exhibited significant clinical signs and none of the stool analyses were negative. However, in naturally infected snakes, intermittent results were found in serial fecal tests. A direct cycle of development was predominant in stool cultures from snakes with both types of infection, and attempts to eliminate the parasite with ivermectin failed. Enteritis was a common gross finding in dead snakes. As previous descriptions of S. ophidiae have presented certain shortcomings, a morphological analysis of the ...

Strongyloides cruzi Rodrigues, 1968 was found in Ophiodes striatus (Spix, 1825) from Itabirito, state of Minas Gerais, Brazil. The morphology of the nematodes obtained was briefly described and compared with previous reports of Strongyloides spp. from lizards. Taxonomic comments about these parasites are presented and a species of Strongyloides, a genus whose members have rarely been reported in lizards, is for the first time observed in an anguid reptile.
