Morphological Variations in Conidia of Arthrobotrys oligospora on Different Media
Most commonly occurring predacious fungus Arthrobotrys oligospora showed great variation in size and shape of conidia on some media. The formation of larger conidia was recorded on beef extract and nutrient agar media. The length of conidia in Richard's YPSS, Sabouraud's, PDA and corn meal agar media was of medium size while smaller conidia were produced on Czapek's, Jensen's, Martin's medium. ...
متن کاملIsolation and Molecular Characterization of Indian Isolates of Nematode Trapping Fungi
Two nematode trapping fungi were isolated from aerated soil samples collected fron Anand district( Gujarat) India and identified on the basis of their culture –morphological characteristics and 18S rRNA gene sequencing as Arthrobotrys oligospora and Duddingtonia flagrans . These fungal isolates were assessed for their trapping efficiency further. Trapping structures such as ring like structures...
متن کاملScreening of Soil and Sheep Faecal Samples for Predacious Fungi: Isolation and Characterization of the Nematode-Trapping Fungus Arthrobotrys oligospora
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...
متن کاملIn vitro predatory activity of conidia of fungal isolates of the Duddingtonia flagrans on Angiostrongylus vasorum first-stage larvae.
INTRODUCTION Angiostrongylus vasorum is a nematode that parasitizes molluscs, dogs, and even man. METHODS The objective was to evaluate the predatory activity of the conidia of two fungal isolates of Duddingtonia flagrans (AC001 and CG722) on first-stage larvae (L1) of A. vasorum in laboratory conditions. RESULTS At the end of the experiment, there were significant reductions (p<0.01) of 74...
متن کاملEffect of the nematophagous fungus, Duddingtonia flagrans, on the larval development of goat parasitic nematodes: a plot study.
Effective alternatives to anthelmintic treatment against nematode parasites of goats are required because of the high prevalence of benzimidazole resistance. Towards this objective, the nematophagous fungus, Duddingtonia flagrans (Df), was used in a plot study against two main parasitic nematode species of goats, Teladorsagia circumcincta (Tcir) and Trichostrongylus colubriformis (Tcol). Worm-f...
