background and purpose: fusarium species are avid producers of secondary toxic and carcinogenic metabolites such as fumonisin. contamination of food and feed products with fumonisin can be hazardous to the health of humans and animals and may lead to agricultural loss. accordingly, in this study, we aimed to evaluate the effects of candida parapsilosis on the growth and fumonisin production of ...

Abstract Sheath rot disease is one of the critical problems limiting rice production. Fusarium spp. pathogens that cause sheath and produce various mycotoxins. The study mycotoxins detection using specific primers their association to pathogenicity important in order comprehend types may occur this disease. objectives are investigate potential pathogen-related relation pathogenicity. This inclu...

Fusarium species section Liseola namely F. fujikuroi, F. proliferatum, F. andiyazi, F. verticillioides, and F. sacchari are well-known plant pathogens on rice, sugarcane and maize. In the present study, restriction analysis of the intergenic spacer regions (IGS) was used to characterize the five Fusarium species isolated from rice, sugarcane and maize collected from various locations in Pen...

A polymerase chain reaction (PCR) based diagnostic assay was used to develop markers for detection of Fusarium verticillioides (=F. moniliforme), a fumonisin producing fungus in maize tissues. Species-specific primers were designed based on sequence data from the polyketide synthase (PKS) gene (FUM1- previously FUM5) responsible for fumonisin production in fungi. Four sets of oligonucleotide pr...

fertility status and distribution of mating type alleles of gibberella moniliformis and g. intermedia, both the causal agents of the foot rot and bakanae of rice, as well as stalk and root rot of corn were studied using specific primers. one hundred and twenty eight single-spore isolates were collected from rice growing areas of guilan and mazandaran and from various corn-growing areas of iran....

Cryptococcus neoformans is a human fungal pathogen that exists as three distinct varieties or sibling species: the predominantly opportunistic pathogens C. neoformans var. neoformans (serotype D) and C. neoformans var. grubii (serotype A) and the primary pathogen C. neoformans var. gattii (serotypes B and C). While serotypes A and D are cosmopolitan, serotypes B and C are typically restricted t...

Aspergillus fumigatus is a widespread opportunistic fungal pathogen causing an alarmingly high mortality rate in immunocompromised patients. Nosocomial infections by drug-resistant A. fumigatus strains are of particular concern, and there is a pressing need to understand the origin, dispersal and long-term evolution of drug resistance in this organism. The objective of this study was to investi...

Levels of mycotoxins produced by Fusarium species in genetically modified (GM) and near-isogenic maize, were determined using multi-analyte, microbead-based flow immunocytometry with fluorescence detection, for the parallel quantitative determination of fumonisin B1, deoxynivalenol, zearalenone, T-2, ochratoxin A, and aflatoxin B1. Maize varieties included the genetic events MON 810 and DAS-591...

Isolates of Bipolaris maydis race T, mating types A and a, and Bipolaris maydis race O, mating types A and a, were compared for ammonium production at two or 10 g/l glucose on a L-asparagine-mineral salts medium in relation to mycelium dry weight, sporulation and pH of the culture medium at six, 10 and 14 d of incubation. Ammonium was detected in all media for all isolates at six days and level...
