GHERBAWY Y.A.M.H., ABDELZAHER H.M.A. (1999): Isolation of fungi from tomato rhizosphere and evaluation of the effect of some fungicides and biological agents on the production of cellulase enzymes by Nectria haematococca and Pythium ultimum var. ultimum.   [Biologicalcontrol, root-rot, fungicides Nectria haematococca, Pythium ultimum var. ultimum]  Czech Mycology 51(2-3): 157-170   (published: 25th May, 1999)
  abstract   Forty-five species and two species varieties belonging to twenty-six genera of fungi were isolated from 30 soil samples from the rhizosphere of tomato plants. The fungi most frequently isolated were Aspergillus flavus, A.fumigatus, A. niger, A. terreus, Gibberella fujikuroi, Nectria haematococca and Rhizopus stolonifer. Ridomil and Vitavax-captan (10, 50 and 100ppm) had no significant effects on the activity of Cl and Cₓ enzymes of Nectria haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but slightly decreased at 100ppm. Vitavax-captan (10, 50 and 100ppm) significantly decreased Cl enzyme activities of N. haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but at 100 ppm it showed a slightly inhibitory effect. Ridomil caused a slight increase in the activity of Cₓ and Cl enzymes by Pythium ultimum var. ultimum at low and moderate doses but the highest dose of Ridomil caused a slight reduction. Vitavax-captan slightly increased the activity of Cₓ and Cl enzymes in P. ultimum var. ultimum. Normal and sterilised filtrates of Myrothecium verrucaria, Penicillium oxalicum and Trichoderma harzianum induced a small decrease in Cl enzyme activity of Nectria haematococca. The sterilised filtrates of the three fungi tested caused greater inhibition compared to the normal filtrate. The production of Cₓ enzyme was slightly increased with normal and sterilised filtrates of Penicillium oxalicum and Trichoderma harzianum, but was significantly increased by both types of filtrates of Myrothecium verrucaria. The two types of filtrate of all fungi tested did not significantly affect the activity of Cl and Cₓ enzymes by lithium ultimum var. ultimum. Production of extracellular protein by Nectria haematococca was not significantly affected by any dose of the tested fungi cides. It was slightly increased by the two types of filtrate of the three tested fungi but significantly increased by the normal filtrate of Myrothecium verrucaria. The normal filtrate of all the fungi tested enhanced extracellular protein production to a greater extent than the sterilised filtrate. Extracellular proteins of Pythium ultimum var. ultimum were slightly increased by all doses of Vitavax-captan and low doses only of Ridomil, also two types of filtrate of all tested fungi caused a slightly increasing effect.

HASHEM M. (2004): Biological control of two phytopathogenic fungal species isolated from the rhizoplane of soybean (Glycine max).   [biological control, soybean, Macrophominaphaseolina, Rhizoctonia solani]  Czech Mycology 56(3-4): 223-238   (published: 22nd December, 2004)
  abstract   Two hundred isolates representing 31 fungal species (20 genera) were recovered from soybean roots. Samples were collected from 12 localities at 3 different growth stages of the crop. The most dominant species were Aspergillus flavus, Fusarium oxysporum, Fusarium solani (Nectria haematococca), Macrophomina phaseolina and Rhizoctonia solani. Pathogenicity tests have proved the ability of Macrophomina phaseolina and Rhizoctonia solani to infect soybean roots and produce the symptoms of damping-off and root-rot diseases.The efficacy of three antagonists (Trichodermaharzianum, Epicoccum nigrum and Paecilomyceslilacinus) as well as two organic compounds (Strom and F-760) was evaluated as to their control of pathogenic fungi . Biocontrol fungi significantly suppressed Macrophominaphaseolina and Rhizoctonia solani in vitro and in vivo. Epicoccum nigrum and Paecilomyces lilacinus suppressed the growth of the pathogens by producing an inhibition zone while Trichoderma harzianum suppressed them by overgrowing. Strom and F-760 showed lower reduction effect of diseases in comparison with the antagonists.

GHERBAWY Y.A.M.H., PRILLINGER H. (2000): Root mycoflora of pepper (Capsicum annuum) antagonistic to Verticillium dahliae.   [Frequency of root fungi, Verticillium dahliae, Chaetomium globosum, Gliocladium roseum, Myrothecium verrucaria, Trichoderma harzianum, pepper seed germination]  Czech Mycology 52(3): 219-226   (published: 7th December, 2000)
  abstract   Thirty-two species belonging to 19 genera of fungi were collected from 30 soil samples from the rhizosphere of pepper plants. The fungal colonies were characterised using classical morphological methods following identification keys. The most frequently isolated fungi were Chaetomiumglobosum, Fusarium oxysporum, Gliocladium roseum, Mucor racemosus, Myrothecium verrucaria, Penicillium aurantiogriseum, P. expansum and Trichoderma harzianum. The crude culture filtrate of Verticillium dahliae at 100% concentration caused sharp decrease in pepper seed germination. Chaetomium globosum, Gliocladium roseum, Myrothecium verrucaria, and Trichoderma harzianum produced a metabolite that retarded radial growth of Verticillium dahliae.

FRAGNER P., MIŘEJOVSKÝ P. (1990): Key to histological identification of causative agents in systemic mycoses II.  Česká Mykologie 44(2): 65-76   (published: 22nd June, 1990)
  abstract   Based on authors’ experience and data from literature the key suggests identification of microscopical fungi according to morphology of mycotic elements found in histological sections from human and animal tissues. Part II: Concise information about species and varieties comprising remarks on occurrence and character of diseases in humans and animals, morphology of fungi in tissues and histopathological pictures.

OTČENÁŠEK M., DVOŘÁK J. (1985): Fungi infecting man. Taxonomy of agents of human mycoses in an alphabetical survey.  Česká Mykologie 39(3): 155-164   (published: 1985)
  abstract   An orientational survey of taxonomy of fungi which have been described as agents of human mycoses is given. An alphabetical list of 163 agents contains data on synonyms of the individual species and organs afflicted by them. The literature citation of the earliest paper calling attention to pathogenicity is provided. Current nomenclature of anamorph and teleomorph stages and their mutual relation is discussed.
