Fusarium contains the most toxigenic and important fungal pathogens, producing a wide range of mycotoxins that include the more toxic secondary metabolites called fumonisins. This study analyzed the presence of common exo-and mycelium-soluble antigens, purified proteins using reducing SDS-PAGE and the expression of antibodies against different fungal pathogens. The results showed the presence of common antigens between pathogens and development of antibodies against antigens from F. circinatum, F. oxysporum and D. pinea. A strong reactivity against the antigens ranged between 0.510 to 0.868 in F. circinatum and F. oxysporum isolates. The reactivity of anti-D. pinea antibodies was relatively low, with the highest absorbance value of 0.650, accompanied by a minimal cross reactivity. Overall, these findings indicated that, antibodies against mycelium-soluble antigens were the most immunoreactive and could be helpful for the development of a rapid Fusarium detection tool for use in various industries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
