Streptococcus suis is an important bacterial swine pathogen and a zoonotic agent. Recently, two surface proteins of S. suis, Fhb and Fhbp, have been described for their capacity to bind factor H-a soluble complement regulatory protein that protects host cells from complement-mediated damages. Results obtained in this study showed an important role of host factor H in the adhesion of S. suis to ...

Fusarium graminearum and F. culmorum are the causing agents of a destructive disease known as Fusarium head blight (FHB). FHB is a re-emerging disease in small grain cereals which impairs both the grain yield and the quality. Most serious consequence is the contamination of grain with Fusarium mycotoxins that are severe threat to humans and animals. Biological control has been suggested as one ...

Gibberella zeae (anamorph: Fusarium graminearum) is the most common cause of Fusarium head blight (FHB) of wheat (Triticum aestivum) worldwide. Aggressiveness is the most important fungal trait affecting disease severity and stability of host resistance. Objectives were to analyze in two field experiments (i) segregation for aggressiveness among 120 progenies from each of two crosses of highly ...

Multistrain mixtures of biocontrol agents which can reduce plant disease to a greater extent than the individual strains of the mixture, commonly, are prepared by blending separately produced fermentation products. Co-cultivation of strains to equivalent biomass yields would provide mixture advantages without incWTing the cost disadvantages of multiple fermentation and processing protocols. Fus...

Numerous potential components involved in the resistance to Fusarium head blight (FHB) in cereals have been indicated, however, our knowledge regarding this process is still limited and further work is required. Two winter wheat (Triticum aestivum L.) lines differing in their levels of resistance to FHB were analyzed to identify the most crucial proteins associated with resistance in this speci...

Title of Document: EVALUATION OF SCAB RESISTANCE QUANTITATIVE TRAIT LOCI (QTL) EFFECTS ON WHEAT Jing Kang, M.S., 2010 Directed By: Associate Professor Dr. José Costa, Department of Plant Science and Landscape Architecture Fusarium Head Blight (FHB) of wheat (Triticum aestivum), caused by Fusarium graminearum, is a disease that periodically strikes the mid-Atlantic region of the USA. Breeding fo...

Deoxynivalenol (DON) is a mycotoxin produced by the plant pathogenic fungi Fusarium graminearum and F. culmorum. These and other closely related fungi cause a disease known as Fusarium head blight (FHB) in small grain cereals. Other mycotoxins produced by FHB-causing fungi include nivalenol, T-2 toxin, and zearalenone. Ingestion of mycotoxin-contaminated food and feed can lead to toxicosis in h...

Head blight of wheat (FHB, scab) caused by Fusarium spp. is a severe fungal disease problem worldwide. Apart from yield and grain quality losses, the contamination of the harvest with toxic fungal metabolites, known as mycotoxins, is of serious impact. In spite of the fact that several sources for resistance against FHB have been found and utilized in hexaploid wheat, virtually no resistant tet...

Infection with fungal pathogens on wheat varieties with different levels of resistance was tested at ambient (NC, 390 ppm) and elevated (EC, 750 ppm) atmospheric CO2 levels in the phytotron. EC was found to affect many aspects of the plant-pathogen interaction. Infection with most fungal diseases was usually found to be promoted by elevated CO2 level in susceptible varieties. Powdery mildew, le...

Tan spot, caused by Pyrenophora tritici-repentis, and fusarium head blight (FHB), the Fusarium graminearum species complex, are among main wheat diseases worldwide. This 3-year field study evaluated effect of soil incorporation calcium silicate, a source silicon (Si), to manage tan spot FHB improve grain yield quality. The Si was compared on two cultivars contrasting in disease resistance assoc...
