Cutaneous larva migrans is a self-limited cutaneous eruption caused by larva of roundworms that do not normally parasitize humans. Ankylostoma brazielensis, the dog and cat hookworm, is the most common agent. The disease is found in tropical and subtropical regions and may be seen in travelers from these regions. We report a case of a 37-year-old Iranian man who had cutaneous larva migrans afte...

a 28-year-old male farmer presented with a chief complaint of itching and extreme dis-comfort on the entire maxillary and mandibular gingivae. he was diagnosed with gingival myiasis and scaling was performed on both jaws. however because of the multiple larvae, complete removal with simple curettage and scaling was not feasible, therefore flap sur-gery was performed on the maxilla. one week lat...

A late instar of the Tetragonoderus (Crossonychus) variegatus Dejean, 1829 larva is described for the first time, and is compared with its first instar, with the larva of another Tetragonoderus species, and with the larva of one Cyclicus species. Habitus and important structures of the larva are illustrated, as well the adult's membranous wings. Some aspects of the natural history of the larva ...

We report that a stage-specific developmental program, dauer larva formation, is temporally regulated by four heterochronic genes, lin-4, lin-14, lin-28, and lin-29. The effects of mutations in these four genes on dauer larva formation have revealed that they regulate two different processes of dauer larva formation: (1) a decision specifying the larval stage at which dauer larva development in...

1. The second-stage larva of the plant parasitic nematode Heterodera rostocfaensis shows very little movement while confined to the egg; on the other hand, the larva of the closely related Meloidogyne incognita is very active 2. Using interference microscopy, it is shown that the water content of the Heterodera larva increases immediately it is liberated from the egg while that of the Meloidogy...
