Background: Duddingtonia flagrans and Monacrosporium thaumasium are promising fungus species in veterinary biological control of gastrointestinal nematodes because of their production capacity of fungal structures (conidia and/or chlamydospores), growth efficiency in laboratory solid media and especially their predatory capacity. However, their large-scale production remains a challenge. This work aimed at evaluating the mycelial mass production of D. flagrans (AC001 and CG722) and M. thaumasium (NF34A) nematophagous fungi under different culture conditions.
Results: The results did not present significant differences (p > 0.05) in mycelia mass production between the isolates cultured under pH 4.0. Furthermore, after 168 hrs., the isolate CG722 presented a lower production of mycelial mass in medium CM (corn meal) (p < 0.05).
Conclusion: We therefore concluded the use of culture media SD (soy dextrose) and CG (corn grits) at pH values between 6.0 and 7.0 is suitable for high mycelial mass production of D. flagrans and M. thaumasium.

Chili anthracnose, caused by , causes significant yield loss in chili production. In this study, we investigated the elicitor properties of a rhamnolipid (RL)-enriched PA3 fraction derived from SWUC02 in inducing systemic resistance in yellow chili seedlings and antifungal activity against CFPL01 (Col). Fractionation of the ethyl acetate extract yielded 12 fractions, with PA3 demonstrating the most effective disease suppression, reducing the disease severity index to 4 ± 7.

Emergomyces africanus is a thermally dimorphic pathogen causing severe morbidity and mortality in immunocompromized patients. Its transition to a pathogenic yeast-like phase in the human host is a notable virulence mechanism. Recent studies suggest polyamines as key players in dimorphic switching, yet their precise functions remain enigmatic.

To address the economic burden caused by livestock parasitic diseases, particularly gastrointestinal nematodes (GIN) and liver flukes, which are exacerbated by growing anthelmintic resistance, researchers are increasingly focusing on biological control strategies as a promising solution. Among these, the fungus Pochonia chlamydosporia has demonstrated promising helminth control properties. This study explored the potential of P.

This study was to assess the digestion and colonic fermentation of two bioactive polysaccharides, EPS-LM and LBPS, and the subsequent influences on human gut microbiota through simulated gastrointestinal systems. EPS-LM, an exopolysaccharide isolated from mycelial culture of a medicinal fungus Cordyceps sinensis Cs-HK1, was characterized as a heteropolysaccharide consisting of Man(108):Gal(52.7):Glc(29.
