A hemorrhagic factor (apicidin) produced by toxic Fusarium isolates from soybean seeds

Article Abstract:

The role of apicidins on the occurrence of hemorrhagic disease syndrome on laboratory rats has been investigated. Apicidins are antiprotozoal agents found in Fusarium species that inhibit parasite histone deacetylase activity. The apicidins used in the study were isolated from wheat cultures of Fusarium sp. strain KCTC 16677. The Fusarium species were originally obtained from soybean seeds from South Korea. Results reveal that rats fed with a diet containing apicidins suffered from body weight loss, hemorrhage in the stomach, intestines and bladder and then died ultimately.

Influence of kernel age on fumonisin B1 production in maize by Fusarium monoliforme

Article Abstract:

Fusarium monoliforme has been discovered to produce fumonisins, a class of mycotoxins, which have been identified as a significant maize pathogen. These fumonisins are a threat to animal and human health since these substances may alter cell morphology, cell to cell interactions, cell surface protein behavior, protein kinase activity and cell growth. Findings have further revealed that differences in fumonisin B1 production among kernels at the different developmental stages remained at significant levels.

Sambutoxin-producing isolates of Fusarium species and occurrence of sambutoxin in rotten potato tubers

Article Abstract:

Sambutoxin, which is found in rotten potatoes, appears to be produced by a large percentage of Fusarium (F.) sambucinum and F. oxysporum bacteria. These species produced sambutoxin more consistently than 11 other isolated Fusarium species. In isolation, F. sambucinum and F. oxysporum produced the toxin at levels between 1.1 and 101.1 migrograms per gram. Nine of 21 rotten potato samples contained between 15.8 and 78.1 nanograms per gram of sambutoxin.
