Dicranoses capsulifex Kieffer and Jörgensen (Lepidoptera: Cecidosidae) is a gall inducing moth associated with Schinus fasciculatus (Griseb.) (Anacardiaceae), with a known distribution restricted to Argentina. It undergoes a one year life cycle (univoltine), with leaf-like galls, and adult with only a half day life span. Male, female, pupa, and gall are redescribed, and the genitalia of both se...

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...

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...

OBJECTIVE To determine the efficacy of combination treatment of Albendazole along with liquid nitrogen in cutaneous larva migrans. STUDY DESIGN Quasi-experimental study. PLACE AND DURATION OF STUDY Abbasi Shaheed Hospital and The Aga Khan Hospital, Karachi, from December 2008 to December 2010. METHODOLOGY Eighteen cases of cutaneous larva migrans were collected and divided into two groups...

Cutaneous larva migrans is a pruritic dermatitis due to the inoculation of helminths larvae in the skin, and it often occurs in children in tropical and subtropical areas. The authors describe an atypical case of cutaneous larva migrans in a 11 year-old child with scalp involvement, an unusual topography for this lesion.

samples of water, sediment and shrimp obtained from hatcheries and culture ponds were collected over a period of four months and were analyzed for vibrio parahaemolyticus. samples included the following: two samples of shrimp larva from two hatchery ponds (wlh); 14 samples of water, sediment and shrimp from 14 culture ponds supplied with shrimp larvae from the same hatchery ponds that were obta...

In this study, we report the rearing of Brachyopa panzeri Goffe, 1945 from larva and elucidate its life circle with a duration pupal stage for first time. We describe puparium B. which morphology was unknown prior to current study. The study showed discrepancies between our observations original description. These allow us redescribe larva, explaining uncertainties that have existed in literatu...

The laboratory test results for visceral larva migrans (VLM) using ELISA for Toxocara canis antibodies employed by the Institute for Medical Research, Kuala Lumpur, is described. A total of 331 serum samples received from hospitals and general practitioners all over Malaysia were tested. The test utilises excretory-secretory antigens obtained from in vitro culture of second stage T. canis larva...

two snail species belonging to genus lymnaea, l.auricularia and l.gedrosiana, were collected from 6 different districts of shadegan area of khoozestan. eight percent of the total collections of the snails revealed the occurrence of larva in them. the prevalence of larva within the snails varied in different districts may be due to different geoclimatic conditions and availability of fresh water...
