From 1997 to 1999, we identified seven human cases of infection by fourth stage larvae of Pseudoterranova decipiens in Chile. All identified larvae were coughed up by the patients. Subjects were 10-55 years old; five were female. Some patients complained of coughing, expectoration, pharyngeal pain, nausea or anal and nasal pruritus. Larvae of three patients were coughed up from 36 h to 7 days a...

FISH-BOL, the Fish Barcode of Life campaign, is an international research collaboration that is assembling a standardized reference DNA sequence library for all fishes. Analysis is targeting a 648 base pair region of the mitochondrial cytochrome c oxidase I (COI) gene. More than 5000 species have already been DNA barcoded, with an average of five specimens per species, typically vouchers with a...

We describe the identification of Mauthner (M-) cell action potentials in an intact zebrafish larva, utilizing recording electrodes located outside the fish: 1. The externally recorded spike occurs at approximately the same time, and its waveform changes with recording site in the same way, as the extracellular M-spike recorded within the central nervous system. 2. The externally recorded M-spi...

we report a case of human nasal myiasis caused by flower fly larva in a 14-year-old rural girl in central province of iran. entomological studies on larva showed the larva as eristalis tenax which is a rarely cause of nasal myiasis. this is the first reported case of e. tenax larva causing human nasal myiasis in iran.

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...

at first, in order to define acute toxicity of diazinon insecticide and butachlor herbicide, acute toxicity tests (lc5096h) were done, based on standard method (1989) o.e.c.d. in static way and for 96 hours. and the amount of acute toxicity (lc5096h) of diazinon and butachlor in 1 to 2 gram vimba vimba persa fry larva was determined to be 0.09 and 0.61 respectively. in order to do histology stu...

This Adverse Outcome Pathway (AOP) describes the linkage between Deiodinase 2 inhibition and increased mortality via reduced posterior swim bladder inflation. The is a gas-filled organ found in many bony fish species typically consists of two chambers. chamber inflates during early development (embryo), while anterior late (larva). Both chambers are important for to control buoyancy has an addi...

Marine biota is a great source of ecosystem services. Recently, the involvement marine organisms in biotechnological applications has been discovered and become useful for development alternative healthy food, natural medicine cosmetics. The most known service provision seafood; however, fishery management to be implemented order avoid fishing exploitation, depletion sea assure recruitment by f...
