Aim of the present investigation was to assess the in vitro efficacy of different plant extracts againsts fungi isolated from bovine mastitis cases. Twenty-six species of yeast, yeast like and moulds were isolated from 200 mastitic milk samples. The isolates were identified based on the staining, cultural and biochemical characteristics. Aqueous extracts of cinnamon leaf, lemon grass, clove, an...

Reports have focused on the emergence of moulds as pathogens in recipients of hematopoietic stem cell transplants. To review the incidence of and risks for mould infections, we examined the records of 5589 patients who underwent hematopoietic stem cell transplantation at the Fred Hutchinson Cancer Research Center (Seattle) from 1985 through 1999. After 1992, the incidence of invasive aspergillo...

The objective of this study was to evaluate biotic interaction between some mould species and active producer of aflatoxin B1 Aspergillus flavus NRRL 3251, co-cultured in yeast-extract sucrose (YES) broth. Twenty-five mould strains of Alternaria spp., Cladosporium spp., Mucor spp., A. flavus and A. niger, used as biocompetitive agents, were isolated from outdoor and indoor airborne fungi, scrap...

Pink snow mold (Mirodochium patch) and gray snow mold [Typhula blight) are the most prevalent and destructive winter diseases on cool-season turfgrass in the northern United States. They are especially destructive in the Intermountain Northwest where deep snow cover may last four to five months. Pentachloronitrobenzene (PCNB, Quintozene) has been use to manage these diseases in turf on golf cou...

The vast repertoire of toxic fungal secondary metabolites has long been assumed to have an evolved protective role against fungivory. It still remains elusive, however, whether fungi contain these compounds as an anti-predator adaptation. We demonstrate that loss of secondary metabolites in the soil mould Aspergillus nidulans causes, under the attack of the fungivorous springtail Folsomia candi...

The author investigated aquatic fungi developing on the seeds of some plants in various types of water bodies of Podlasie Province. The bait method was used to isolate the fungi. Seventy-four aquatic fungal species were found on seeds of three species of plants: Cannabis sativa hemp-seeds 59, Fagopyrum esculentum buckwheat-seeds 55 and on Vicia sativa vetch-seeds 44 in water of four various bod...

Pollen samples collected in the spring of 2002 in 8 south-western Slovakia localities and 40 live individuals of bumblebee were analyzed for the presence of bacteria and microscopic fungi. Microorganisms occurring on pollen and bumblebees were identified using cultivation and microscopic methods supplemented with biochemical tests. In the pollen were found fermenting and non-fermenting Gram-neg...
