Adherence and motility characteristics of clinical Acinetobacter baumannii isolates
Acinetobacter baumannii continues to be a major health problem especially in hospital settings. Herein, features that may play a role in persistence and disease potential were investigated in a col...
Autoaggregation of Xylella fastidiosa cells is influenced by type I and type IV pili
Autoaggregation of widely dispersed Xylella fastidiosa cells into compact cell masses occurred over a period of hours following 7 to 11 days of growth in microfluidic chambers. Studies involving th...
Cell Wall-Degrading Enzymes Enlarge the Pore Size of Intervessel Pit Membranes in Healthy and Xylella fastidiosa-Infected Grapevines
The pit membrane (PM) is a primary cell wall barrier that separates adjacent xylem water conduits, limiting the spread of xylem-localized pathogens and air embolisms from one conduit to the next. T...
DNA microarray-based genome comparison of a pathogenic and a nonpathogenic strain of Xylella fastidiosa delineates genes important for bacterial virulence
Xylella fastidiosa is a phytopathogenic bacterium that causes serious diseases in a wide range of economically important crops. Despite extensive comparative analyses of genome sequences of Xylella...
Expanding Role of Type II Secretion in Bacterial Pathogenesis and Beyond
Type II secretion (T2S) is one means by which Gram-negative pathogens secrete proteins into the extracellular milieu and/or host organisms. Based upon recent genome sequencing, it is clear that T2S...
Global Expression Profile of Biofilm Resistance to Antimicrobial Compounds in the Plant-Pathogenic Bacterium Xylella fastidiosa Reveals Evidence of Persister Cells
Investigations of biofilm resistance response rarely focus on plant-pathogenic bacteria. Since Xylella fastidiosa is a multihost plant-pathogenic bacterium that forms biofilm in the xylem, the beha...
HecA, a member of a class of adhesins produced by diverse pathogenic bacteria, contributes to the attachment,, aggregation, epidermal cell killing, and virulence phenotypes of Erwinia chrysanthemi EC16 on Nicotiana clevelandii seedlings
Erwinia chrysanthemi is representative of a broad class of bacterial pathogens that are capable of inducing necrosis in plants. The E. chrysanthemi EC16 hecA gene predicts a 3,850-aa member of the ...
N-Acetylcysteine in Agriculture, a Novel Use for an Old Molecule: Focus on Controlling the Plant-Pathogen Xylella fastidiosa
Xylella fastidiosa is a plant pathogen bacterium that causes diseases in many different crops. In citrus, it causes Citrus Variegated Chlorosis (CVC). The mechanism of pathogenicity of this bacteri...
Pattern Formation Exhibited by Biofilm Formation within Microfluidic Chambers
This article investigates the dynamics of an important bacterial pathogen, Xylella fastidiosa, within artificial plant xylem. The bacterium is the causative agent of a variety cif diseases that str...
Polysaccharide Compositions of Intervessel Pit Membranes Contribute to Pierce's Disease Resistance of Grapevines
Symptom development of Pierce's disease (PD) in grapevine (Vitis vinifera) depends largely on the ability of the bacterium Xylella fastidiosa to use cell wall-degrading enzymes (CWDEs) to break up ...
Sample sequencing of a selected region of the genome of Erwinia carotovora subsp atroseptica reveals candidate phytopathogenicity genes and allows comparison with Escherichia coli
Genome sequencing is making a profound impact on microbiology. Currently, however, only one plant pathogen genome sequence is publicly available and 2 no genome-sequencing project has been initiate...
Small RNA populations for two unrelated viruses exhibit different biases in strand polarity and proximity to terminal sequences in the insect host Homalodisca vitripennis
Next generation sequence analyses were used to assess virus-derived small RNA (vsRNA) profiles for Homalodisca coagulata virus-1 (HoCV-1), family Dicistroviridae, and Homalodisca vitripennis reovir...
