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...
Predator-prey interactions are vital determinants in the natural selection of behavioral traits. Gentle touch to the anterior half of the body of Caenorhabditis elegans elicits an escape response in which the animal quickly reverses and suppresses exploratory head movements [1, 2]. Here, we investigate the ecological significance of the touch response in predator-prey interactions between C. el...
Our screening for new antiprotozoal antibiotics as described by Nemecet al.1* has revealed a very high incidence of cultures with antiprotozoal activity in the Fungi imperfecti. Nearly all species of the Fungi imperfecti tested are "predacious fungi" characterized by their ability to trap and kill nematodes and/or protozoa2), Dactylaria lutea Routien, obtained from the culture collection of the...
This review describes the current research status regarding implementation of predatory fungi in biological control approach bird gastrointestinal (GI) parasitosis. The main GI parasites Galliformes (e.g., broilers, layers, peacocks, pheasants) and Ratites ostriches, emus, rheas) are addressed, as well their impact on farms, zoos, private collections. characteristics biocontrol with briefly des...
Nematode-trapping fungi are "carnivorous" and attack their hosts using specialized trapping devices. The morphological development of these traps is the key indicator of their switch from saprophytic to predacious lifestyles. Here, the genome of the nematode-trapping fungus Arthrobotrys oligospora Fres. (ATCC24927) was reported. The genome contains 40.07 Mb assembled sequence with 11,479 predic...
In their natural habitat, bacteria are consumed by bacterivorous nematodes; however, they are not simply passive preys. Here we report a defensive mechanism used by certain bacteria to mobilize nematode-trapping fungi to kill nematodes. These bacteria release urea, which triggers a lifestyle switch in the fungus Arthrobotrys oligospora from saprophytic to nematode-predatory form; this predaciou...
Aquatic nematode-trapping hyphomycetes have rarely been studied. The current study examined 1000 waterlogged soil samples in order to systematically investigate resources of aquatic nematode-trapping hyphomycetes and to compare species diversity and community similarities in polluted and unpolluted aquatic environments. Many nematode-trapping hyphomycetes live in shallow freshwater (at a water ...
