Cutaneous larva migrans (CLM) is a rare serpiginous cutaneous eruption caused by accidental penetration and migration in the skin with infective larvae of nematode that normally do not have the human as their host. Although CLM has a worldwide distribution, the infection is most frequent in warmer climates. More recently, they have been increasingly imported from the tropics or subtropics by tr...

Scanning electron microscopy (SEM) was employed to observe the effects of ivermectin (IVM), diethylcarbamazine (DEC), and albendazole (ALB) alone, and the drugs in combination (ALB+IVM and ALB+DEC) against infective third stage larvae (L3) of nocturnally subperiodic (NSP) Brugia malayi (Narathiwat strain) in vitro. IVM, at a concentration of 10(-4) M, killed L3 within 1-2 h. The SEM data showed...

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 o...

Anguina plantaginis n. sp., parasitic on Plantago aristata, is described and illustrated. This new species is most closely related to A. klebahni, A. millefolii, A. mobilis, and A. moxae and is characterized as follows: moderate body size for the genus; absence of esophageal "storage organ"; postvulval uterine sac extending about 45% of vulva-anus distance; crustaformeria of young females longe...

The ability of Steinernema feltiae or Heterorhabditis bacteriophora infective juveniles (IJ), when applied to the soil surface, to infect a Galleria mellonella larva at the base of a soil-filled cup (276 cm(3)) was evaluated in the presence and absence of 100 larvae of a non-target insect, the aphid midge Aphidoletes aphidimyza, near the soil surface. In all four trials with either S. feltiae o...

over one-year period, 150 pasture soil samples and 138 sheep faecal samples, collected from different parts of iran were screened for the presence of nematophagous fungi. the samples were cultured at 25ºc on chloramphenicol-2% water agar (chf-wa) plates in the presence of haemonchus contortus third stage larvae (l3) and checked over a two-month period for characteristic conidia, conidiophores a...

BACKGROUND Geohelminths are parasites that stand out for their prevalence and wide distribution, depending on the soil for their transmission. AIMS The aim of this work was to evaluate the predatory capacity of the fungal isolate of the genus Duddingtonia (CG768) on third stage larvae (L3) of Ancylostoma spp. in beach sand under laboratory conditions. METHODS In the assay A five treatment g...

Abstract The effect of four diets on the performance Dorper lambs that were artificially mix-infected with 1000 infective larvae (L3) Haemonchus contortus and L3 Trichostrongylus colubriformis every three days for 12 weeks was evaluated. For each diet, one infected group (n = 7) control 4) set up. contained following proportions hay (H) concentrate (C): Diet 1 - 100%H; 2 75%H:25%C; 3 50%H:50%C;...

An article in a recent issue of this journal by Dr. A. C. Chandler on soil acidity and survival of hookworm.larvae begins as follows: " It is a prevalent opinion that acidity in soil has a tendency to shorten the life of infective hookworm larvae. Hirst (1924), for instance, says "a markedly acid reaction is also most unfavourable to the continued survival of hookworm larvae" and remarks that t...

The infective larva of Litomosoides yutajensis Guerrero et al., 2003, a parasite of the bat Pteronotus pamellii, is described; it is distinct from congeneric infective larvae by the absence of caudal lappets. The life cycles of five other species of Litomosoides are known; three are parasites of rodents, one of a marsupial and one of a bat. As with these species, the experimental vector of L. y...
