Background: Saprophytes are one of the agents causing nail dystrophy. Saprophytes can invade healthy nail or may invade nails previously damaged in the course of other diseases and grow with suitable conditions. The reported incidence of saprophytic nails is between 1.43-17.6% . Saprophytes preferably invade the nails on the big toes, especially in individuals above 60 years. The most etiolog...
Mycotoxins such as Citrinin are small toxic molecules produced by a great variety of microorganism, which encompass several classes of secondary metabolites with no common chemical structure or mode of action. Citrinin produces by different species of Penicillium. Today, the cold atmospheric pressure plasma (CAPP) method has a potential for mycotoxin detoxification. In this study, a new and pro...
Compound feed and the raw materials used in their production are potential vectors of microbiological contamination food chain. The purpose this study was to microbiologically asses (maize, wheat, soybean meal, sunflower meal), broiler compound (starter, grower, finisher) from a representative mill Romania; contaminants that were analyzed yeasts molds, Salmonella spp., Escherichia coli, Clostri...
Several penicillin-producing fungi were examined for ability to produce 6-aminopenicillanic acid (6-APA) and penicillin acylase. 6-APA was found in corn steep liquor fermentations of Trichophyton mentagrophytes, Aspergillus ochraceous, and three strains of Penicillium sp. 6-APA was not detected in fermentations of Epidermophyton floccosum although penicillins were produced. 6-APA formed a large...
The effects of three fungicide seed treatments (triazole plus imidazole (tri+im), fuberidazole (fub) and carboxin plus thiram (car+thi)) on establishment and yield of a number of paired seed lines of wheat cultivars with different levels of Fusarium infection were examined. Without seed treatment, lines of four cultivars with an average of 48% of seeds infected with Fusarium had between 9% and ...
Relationship Between Host Acidification and Virulence of Penicillium spp. on Apple and Citrus Fruit.
ABSTRACT Penicillium expansum, P. digitatum, and P. italicum acidify the ambient environments of apple and citrus fruit during decay development. They use two mechanisms for this: the production of organic acids, mainly citric and gluconic, and NH(4)(+) utilization associated with H(+) efflux. Exposure of P. expansum and P. digitatum hyphae to pH 5.0 increased their citric acid production, comp...
