the lernaeopodidae is a cosmopolitan family of copepods parasitic on both elasmobranchs and teleosts in marine and freshwater habitats. trichiurus lepturus l. is a commercially valuable bentho-pelagic fish inhabiting continental shelves and slopes worldwide. in the present study 74 specimens of t. lepturus were caught in the persian gulf, 12 of which were infected with female brachiella trichiu...

The present study is based on the investigation of a soil hyphomyces, Paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode Meloidogyne javanica on tomato in greenhouse conditions. P. lilacinus, effectively promoted the growth of plants inoculated with M. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

Background: The nematode species belonging to genus Anisakis occur at their third larval stage in numerous marine teleost fish species worldwide and known to cause accidental human infection through the ingestion of raw or undercooked fish or squids. They may also draw the attention of consumers because of the visual impact of both alive and dead worms. Therefore, the information on their geogr...

Objective(s): Baicalein (BC), a phytoestrogen of the flavonoid family shows beneficiary and adverse effects. Effect of BC on reproduction is still not understood. Reproductive toxic effects on female mice were tested in this study.Materials and Methods: Inseminated Wistar mice were divided into four groups and administered IP with 30, 60, and 90 mg/Kg body weight of BC on gestation daydays 11, ...

The swimming behavior of the nematode Caenorhabditis elegans is investigated in aqueous solutions of increasing viscosity. Detailed flow dynamics associated with the nematode’s swimming motion as well as propulsive force and power are obtained using particle tracking and velocimetry methods. We find that C. elegans delivers propulsive thrusts on the order of a few nanonewtons. Such findings are...

A new root-knot nematode, Meloidogyne aquatilis n. sp., attacking the roots of Spartina pectinata Link growing in the Ottawa River is described and illustrated. Meloidogyne aquatilis is distinguished from M. graminis by the light brown body color and by the absence of perineal lateral fields in the female. The male differs by the shorter stylet and by the hemizonid being separated by 7-9 annule...
