“…nov. and F. thapsinum from Nigerian grains, in addition to the previously reported F. andiyazi and F. verticillioides (Marley et al 2004, Afolabi et al 2006, Makun et al 2009. Fusarium verticillioides and other members of the FFSC, including those found in the present study (F. andiyazi, F. proliferatum, F. pseudonygamai, F. subglutinans and F. thapsinum), have been documented in cereals and natural environments in different countries (Fandohan et al 2005, Ncube et al 2011, Leyva-Madrigal et al 2014, O'Donnell et al 2015, Moussa et al 2017, Choi et al 2018, Chala et al 2019. The specificity of F. andiyazi and F. thapsinum to sorghum, which we observed here, agrees with literature (Marley et al 2004, Pena et al 2018, Chala et al 2019.…”

“…Fumonisins were produced as expected only by F. verticillioides, although the cultures of two strains, DTO 421-G2 and DTO 424-H5, did not contain any of the fumonisins. Fumonisin production is a signature in this species as well as in other selected members of the FFSC not found in the present study (Makun et al 2011, Ncube et al 2011, de Oliveira Rocha et al 2011, Fanelli et al 2012, Rocha et al 2016, Choi et al 2018.…”

A second multi-locus analysis, based on the five gene regions above-mentioned, was used to determine the genetic exclusivity of an undescribed phylogenetic clade belonging to the Fusarium fujikuroi species complex (FFSC, O'Donnell et al 2015, Choi et al 2018.

Mycological investigation of various foods (mainly cowpea, groundnut, maize, rice, sorghum) and agricultural soils from two states in north-central Nigeria (Nasarawa and Niger), was conducted in order to understand the role of filamentous fungi in food contamination and public health. A total of 839 fungal isolates were recovered from 84% of the 250 food and all 30 soil samples. Preliminary identifications were made, based on macro- and micromorphological characters. Representative strains (n = 121) were studied in detail using morphology and DNA sequencing, involving genera/species-specific markers, while extrolite profiles using LC-MS/MS were obtained for a selection of strains. The representative strains grouped in seven genera (Aspergillus, Fusarium, Macrophomina, Meyerozyma, Neocosmospora, Neotestudina and Phoma). Amongst the 21 species that were isolated during this study was one novel species belonging to the Fusarium fujikuroi species complex, F. madaensesp. nov., obtained from groundnut and sorghum in Nasarawa state. The examined strains produced diverse extrolites, including several uncommon compounds: averantinmethylether in A. aflatoxiformans; aspergillimide in A. flavus; heptelidic acid in A. austwickii; desoxypaxillin, kotanin A and paspalitrems (A and B) in A. aflatoxiformans, A. austwickii and A. cerealis; aurasperon C, dimethylsulochrin, fellutanine A, methylorsellinic acid, nigragillin and pyrophen in A. brunneoviolaceus; cyclosporins (A, B, C and H) in A. niger; methylorsellinic acid, pyrophen and secalonic acid in A. piperis; aspulvinone E, fonsecin, kojic acid, kotanin A, malformin C, pyranonigrin and pyrophen in A. vadensis; and all compounds in F. madaense sp. nov., Meyerozyma, Neocosmospora and Neotestudina. This study provides snapshot data for prediction of food contamination and fungal biodiversity exploitation.

Genetic Characterization of Fungal Biodiversity in Storage Grains: Towards Enhancing Food Safety in Northern Uganda

Worldwide fungal contamination leads to both quantitative and qualitative grain losses during crop growth and/or storage. A greater proportion of grains contamination with toxins often occurs in sub-Saharan Africa, where control measures are limited. We determined fungal diversity and their toxin production ability in household grains meant for human consumption to highlight the risk of mycotoxin exposure among people from northern Uganda. The study underlines the high diversity of fungi that group into 15 genera; many of which are plant pathogens with toxigenic potential. Fusarium verticillioides was the most common fungal species isolated from household grains. The study also indicates that northern Uganda is favored by a high proportion of toxigenic isolates of F. verticillioides, F. andiyazi, and F. proliferatum, which are characterized by a high fumonisins production capability. The fumonisins production ability was not dependent on the species, grain types, and haplotype group to which the isolates belong. The contamination of most household grains with fungi capable of producing a high amount of toxin shows that most people are exposed to an elevated amount of mycotoxins, which shows the frequent problems with mycotoxins that have been reported in most parts of sub-Saharan Africa.

“…The vascular systems of F. proliferatuminfected crops are destroyed. It causes rot of the stems, stalks, roots, owers, and ears of maize [1][2][3] and decreases its yield and quality remarkably. In addition, the mycotoxins of fumonisin B1, fumonisin B2, beauvericin, enniatins, fusaproliferin, and moniliformin are produced by F. proliferatum during infection processes.…”
