Predatory activity of nematophagous fungi on infective larvae of Ancylostoma sp...
Carvalho, R.O.; Araújo, J.V.; Braga, F.R.; Araujo, J.M.; Silva, A.R.; Tavela, A.O.The predatory capacity of nematophagous fungi Duddingtonia flagrans (AC001), Monacrosporium thaumasium (NF34a), M. appendiculatum (CGI), M. sinense (SF53), Arthrobotrys conoides (I-40), A. cladodes (CG719) and A. robusta (I-31) on infective Ancylostoma sp. larvae (L3) was evaluated. Compared with the control without fungi there was a significant reduction (P < 0.05) of 87.02%, 82.74%, 47.93%, 60.49%, 76.89%, 71...
Optimizing protease production from an isolate of the nematophagous fungus Dudd...
Braga, F.R.; Araújo, J.V.; Soares, F.E.F.; Araujo, J.M.; Genier, H.L.A.; Silva, A.R.; Carvalho, R.O.; Queiroz, J.H.; Ferreira, S.R.Protease production from Duddingtonia flagrans (isolate AC001) was optimized and the larvicidal activity of the enzymatic extract was evaluated on infective horse cyathostomin larvae (L3). Duddingtonia flagrans was grown in liquid medium with eight different variables: glucose, casein, bibasic potassium phosphate (K 2 HPO 4 ), magnesium sulphate (MgSO 4 ), zinc sulphate (ZnSO 4 ), ferrous sulphate (FeSO 4 ), co...
Pochonia chlamydosporia fungal activity in a solid medium and its crude extract...
Braga, F.R.; Araújo, J.V.; Araujo, J.M.; Frassy, L.N.; Tavela, A.O.; Soares, F.E.F.; Carvalho, R.O.; Queiroz, L.M.; Queiroz, J.H.The present study aimed to evaluate the ovicidal activity (type 3 effect) of VC1 and VC4 isolates of Pochonia chlamydosporia in a solid medium and the action of a crude extract of P. chlamydosporia against eggs of Ascaridia galli. To evaluate ovicidal activity in culture medium, 1000 A. galli eggs were plated on Petri dishes containing 2% water-agar with grown fungal isolates (VC1 or VC4) and without fungus (co...
Biological control of Ancylostomosis in dogs using the nematode-trapping fungus...
Carvalho, R.O.; Araújo, J.V.; Braga, F.R.; Araujo, J.M.; Silva, A.R.; Frassy, L.N.; Alves, C.D.F.; Ferreira, S.R.Parasitic nematodes Ancylostoma caninum and Ancylostoma braziliense affect dogs and cats and have great medical and veterinary importance for their high prevalence, zoonotic potential, cosmopolitan characteristic and soil contamination by eggs and larvae. In order to evaluate the efficiency of the nematophagous fungus Monacrosporium thaumasium (isolate NF34a) in the biological control of dog hookworm, 12 adult ...
Ovicidal activity of Paecilomyces lilacinus on Moniezia sp. eggs
Braga, F.R.; Araújo, J.V.; Araujo, J.M.; Carvalho, R.O.; Silva, A.R.; Campos, A.K.; Tavela, A.O.The ovicidal activity of Paecilomyces lilacinus was evaluated on Moniezia sp. eggs. Eggs of Moniezia sp. were incubated on plates with 2% agar-water inoculated with grown fungal isolates and a control treatment without fungus. After 5, 10 and 15 days post-inoculation, the eggs were removed and classified according to the following parameters: effect type 1, lytic effect without morphological damage to eggshells...
Duddingtonia flagrans, Monacrosporium thaumasium and Pochonia chlamydosporia as...
Braga, F.R.; Araújo, J.V.; Silva, A.R.; Araujo, J.M.; Carvalho, R.O.; Campos, A.K.; Tavela, A.O.; Ferreira, S.R.; Frassy, L.N.; Alves, C.D.F.The action of four fungal isolates of the species Duddingtonia flagrans (AC001), Monacrosporium thaumasium (NF34a) and Pochonia chlamydosporia (VC1 and VC4) on eggs of Oxyuris equi and Austroxyuris finlaysoni was evaluated in two assays (A and B). Eggs of O. equi (Test A) and A. finlaysoni (Test B) were plated on Petri dishes with 2% water-agar with grown fungal isolates and control without fungus. After 5, 10 ...
Predatory activity of the fungi Duddingtonia flagrans, Monacrosporium thaumasiu...
Braga, F.R.; Carvalho, R.O.; Araujo, J.M.; Silva, A.R.; Araújo, J.V.; Lima, W.S.; Ferreira, S.R.; Tavela, A.O.Angiostrongylus vasorum is a nematode that parasitizes domestic dogs and wild canids. We compared the predatory capacity of isolates from the predatory fungi Duddingtonia flagrans (AC001), Monacrosporium thaumasium (NF34), Monacrosporium sinense (SF53) and Arthrobotrys robusta (I31) on first-stage larvae (L 1 ) of A. vasorum under laboratory conditions. L 1 A. vasorum were plated on 2% water-agar (WA) Petri dis...
