background: gnathostoma spinigerum causes larva migran in human which is endemic in southeast asia. information regarding larva migration is limited. in this study, we investigated the parasite migra­tion by recovery of worms from the whole body of mouse after oral infection with advanced third stage larvae (al3). the percentage of blood eosinophils was examined in parallel. methods: mice were ...

Small strongyles (‘small red worm’) are the most common and harmful intestinal worm of horses worldwide and account for 95% of faecal worm egg count burdens. The adult worms are small (1-2 cm long) and live in the horse’s large intestine (Fig. 1). The adult worms lay eggs which pass onto the pasture in the manure. Larvae (immature worm) hatch from the egg and cleverly migrate up blades of grass...

we describe a 61-year-old man who developed a mild gastrointestinal discomforts including diarrhea associated with feces containing many larvae similar to rhabditiform larvae of strongyloides stercoralis diagnosed finally as diploscapter coro­nata, a free-living nematode. this case is unusual infection in human and there are a few reports of this worm as a real pa­rasite. microscopically, diplo...

The present study was conducted to assess the effects of different feed regimes for nursing knife fish (Notopterus notopterus) larvae up 35 days. Larvae were reared in 50 L tank with Moina, Tubifex worm, and commercial powder substituted culture Feeding worms during found best growth rate survival fish. result obtained when fed 0-5 days 6-20 tubifex 21–35-day weight gain 0.31 g, length 2.36 cm,...

The peri-parturient period is crucial for controlling worms as the acquired immunity of ewes is disrupted, resulting in an increase in faecal worm egg counts. Two hypotheses were tested in this experiment - that ewes bred for worm resistance would have lower faecal worm egg counts than unselected control ewes, during late pregnancy and lactation, under similar but separate grazing areas; and al...

The type and level of infective strongylid nematode larvae on pasture were monitored fortnightly from July 1995 to June 1996 in the central highlands of Kenya. The number of larvae on pasture was moderate, reaching > 1,200 kg(-1) dry matter of grass during the period of, and soon after, the rains, and remained low in the dry seasons. The number of larvae on pasture was directly related to the r...

hook worm (necator americanus) is one of the major pathogenic parasites in the north of iran. neonatal hamsters 1-3 days old showed a high degree of susceptibility to necator americanus infection and the parasite reached to sexually mature stages in six weeks following skin exposure. this method could be used for production of egg, larvae and adult worms. in this study neonatal hamsters were in...

The protein Lethal giant larvae (LGL) regulates cell polarity in diverse animal models. Now, an LGL orthologue has been identified in the worm Caenorhabditis elegans and is shown to function redundantly with a worm-specific polarity protein, PAR-2.

WELLS C. and BEHNKE .I. M. 1988. The course of primary infection with Necutoramericanus in syngeneic mice. Internationul Journul for Purasitology 18: 41-5 1. A panel of syngeneic mouse strains was compared for susceptibility to infection with a hamster adapted strain of N. americunus. Lung worm burdens were compared 4-5 days after percutaneous exposure to 190-375 larvae. SJL and DBA/l were most...
