We present a case of visceral larva migrans which came as a complete histologic surprise. The patient was operated as a case of chronic cholecystitis and was found at operation to have multiple hepatic nodules. A cholecystectomy with a biopsy of the liver nodule was performed. Histopathologically a diagnosis of visceral larva migrans was made. To our knowledge this is the first case report of t...

Human anisakiasis is a zoonosis acquired by eating raw or undercooked infected seafood. Herein, we report a case of acute dysentery caused by anisakiasis in a 64-year-old man in Malaysia. A colonoscopy was performed and a nematode larva was found penetrating the mucosa of the ascending colon. Bleeding was observed at the site of penetration. Y-shaped lateral epidermal cords were seen from the c...

The mature larva of Stenichnus collaris is re-described on the basis of a shed larval skin. This is the first description of an immature Stenichnus identified by rearing to an adult beetle, and not only by collecting the larva in association with adults, as in previously published works. New data on the life history of St. collaris are provided, and possible serial homology of chaetotaxic struc...

The Larva monitoring tool has been successfully applied to a number of industrial Java systems, providing extra assurance of behaviour correctness. Given the increased interest in concurrent programming, we propose Elarva, an adaptation of Larva for monitoring programs written in Erlang, an established industry-strength concurrent language. Object-oriented Larva constructs have been translated ...

I N addition to the principal imaginal discs (cephalic, labial, wing, haltere, leg and genital), the larva in Cyclorrhapha carries as discrete components the rudiments of the imaginal segmental abdominal hypodermis, salivary glands, fore-, midand hind-gut, lateral cerebral ganglia and segmental tracheal system (Snodgrass, 1924; Bodenstein, 1950; Shatoury, 19566; Anderson, 1964, etc.). The embry...

The ultimate stadium larva of Neuraeschna claviforcipata is described and illustrated based on an F-0 exuvia of a reared female from northern Amazonas State, Brazil. This larva differs from the other two known larvae of the genus in lacking the spiny lateral prominence of the mandible, and in having only a short spine each side of the median cleft of the prementum; labium is shorter and cercus ...

Figure 1. The giant tubeworm Riftia pachyptila. (A) Dense aggregation at a hydrothermal vent of the East Pacific Rise. (B) Life cycle with aposymbiotic phase from fertilized egg to settled larva (blue), and symbiotic phase from larva in metamorphosis to adult (red). Infection of Endoriftia (red) from a free-living microbial community occurs in the larva. (C) Relationships of siboglinids outlini...

An anisakid nematode larva found in cod sold in the state of Minas Gerais, Brazil was studied by light and scanning electron microscopy and by a molecular approach. Mitochondrial cytochrome c-oxidase subunit 2 (mtDNA cox-2), 28S rRNA and ITS1, 5.8S and ITS2 regions were amplified using the polymerase chain reaction and sequenced to evaluate the phylogenetic relationships of the larva. The genet...

The nurse cell-parasite complex of Trichinella spiralis is unlike anything else in Nature. It is derived from a normal portion of striated skeletal muscle cell and develops in a matter of 15 to 20 days after the larva invades that cell type. What are the molecular mechanisms at work that result in this unique relationship? Here, Dickson Despommier presents a hypothesis to account for its format...
