Molds are persistent and harmful but receive far less research attention compared with pathogenic bacteria. With the increase in microbial resistance to single-chain surfactant antimicrobial agents, it is crucial to investigate how surfactant structures affect the antimicrobial activity of surfactants. Here, we have studied the antimold efficacy of a series of oligomeric cationic quaternary ammonium surfactants at varying oligomerization levels with or without dynamic covalent imine bonds.

Background: Sheep coccidiosis could disturb the balance of intestinal microbiota, causing diarrhea, and even death in lambs. Chemical drugs are the primary method of treating sheep coccidiosis, but their use will bring drug resistance, toxic side effects, drug residues, and other problems. Chinese herbal medicines are investigated as alternative methods for controlling coccidian infections.

Aflatoxin contamination of corn can occur when developing kernels are infected by the plant pathogen Aspergillus flavus. One route of infection is from airborne conidia. We executed a series of experiments within the corn canopy during two growing seasons and in two states to document the abundance and dynamics of the airborne A.

Fungi are the most important group of plant pathogens, responsible for many of the world's most devastating crop diseases. One of the reasons they are such successful pathogens is because several fungi have evolved the capacity to breach the tough outer cuticle of plants using specialized infection structures called appressoria. This is exemplified by the filamentous ascomycete fungus Magnaporthe oryzae, causal agent of rice blast, one of the most serious diseases affecting rice cultivation globally.

Cry proteins, commonly found in Gram-positive soil bacteria, are used worldwide as aerial sprays or in transgenic plants for controlling crop pest populations and insect vectors. Via PCR analysis, a spore producing soil isolate (BV5) was speculated to encode a Cry gene. Partial nucleotide sequence of the amplified PCR fragment showed homology with the Cry8 genes present in GenBank.
