Analysis of Fusarium head blight (FHB) pathogen diversity revealed that 3ADON producing Fusarium graminearum are prevalent in North America and identified significant population structure associated with trichothecene chemotype differences (F(ST)>0.285; P<0.001). In addition, we identified a trichothecene chemotype cline in Canada and documented a recent and significant shift in FHB pathogen co...

Fungal and oomycete plant pathogens cause destructive diseases in crops and pose real economic and food security threats [1]. These filamentous, eukaryotic organisms can also upset natural ecosystems when they spread invasively [2]. The capability of plant immune systems to detect and respond to pathogen effector proteins is a major determinant of disease susceptibility. Plant pathogen effector...

Aeromonas hydrophila is a Gram-negative, oxidase-positive, facultative, anaerobic, opportunistic aquatic pathogen. A. hydrophila produces virulence factors, such as hemolysins, aerolysins, adhesins, enterotoxins, phospholipase and lipase. In addition to isolation from aquatic sources, A. hydrophila has been isolated from meat and meat products, milk and dairy products, and vegetables. However, ...

Introduction The outbreak of Shiga Toxin producing Escherichia coli O104:H4 linked to bean sprouts led to over 3800 confirmed cases of illness that included more than 823 cases of Haemolytic Uremic Syndrome (HUS) and 44 deaths (Frank et al., 2011). Although it appeared that the O104:H4 serotype came from nowhere the pathogen had actually been isolated in Germany 10 years ago. The outbreak in Ge...

BARRIER PROPERTIES OF MUCUS Hasan M. Yildiz, Chemical Engineering, Northeastern University Mucus, a complex network consisting of microand nano-scale fluid-filled domains formed via mucin glycoprotein interactions, provides a barrier through which nutrients and orally delivered drugs must penetrate before entering the circulatory system. Mucus provides a significant, yet poorly characterized ba...

Plant diseases caused by fungi, oomycetes, viruses, and bacteria are devastating both to the economy and to the food supply of a nation. Therefore, the development of new, rapid methods to identify these pathogens is a highly important area of research that is of international concern. MS-based proteomics has become a powerful and increasingly popular approach to not only identify these pathoge...

conclusions the present study was the first report on the isolation and identification of t. ptyseos from pif in iran. t. ptyseos are frequently present in various kinds of foods; therefore, further investigation on these samples is required. it is necessary to track the t. ptyseos in a wide variety of foods and individuals especially in immunocompromised people such as human immunodeficiency v...

Cell-based biosensors have been proposed for use as function-based detectors of toxic agents. We report the use of Betta splendens chromatophore cells, specifically erythrophore cells, for detection of food-associated pathogenic bacteria. Evaluation of erythrophore cell response, using Bacillus spp., has revealed that this response can distinguish pathogenic Bacillus cereus from a non-pathogeni...

The animal gut plays a central role in tackling two common ecological challenges, nutrient shortage and food-borne parasites, the former by efficient digestion and nutrient absorption, the latter by acting as an immune organ and a barrier. It remains unknown whether these functions can be independently optimised by evolution, or whether they interfere with each other. We report that Drosophila ...
