Vibrio cholerae ToxR Downregulates Virulence Factor Production in Response to Cyclo(Phe-Pro)

open access: yesmBio, 2013
Vibrio cholerae is an aquatic organism that causes the severe acute diarrheal disease cholera. The ability of V. cholerae to cause disease is dependent upon the production of two critical virulence determinants, cholera toxin (CT) and the toxin ...

Description of extraintestinal pathogenic Escherichia coli based on phylogenetic grouping, virulence factors, and antimicrobial susceptibility

open access: yesIranian Journal of Microbiology, 2023
Background and Objectives: Extraintestinal pathogenic Escherichia coli (ExPEC) is a recently recognized and highly diverse pathotype of E. coli. Its significance as a pathogen has increased due to the emergence of hypervirulent and multidrug-resistant ...

Breaking the bad: Bacillus blocks fungal virulence factors

open access: yesMicrobial Cell, 2017
Fungal pathogens rely on the production of specific virulence factors during infection. Inhibiting such factors generally results in reduced fungal pathogenicity.

Granzyme B Attenuates Bacterial Virulence by Targeting Secreted Factors

open access: yesiScience, 2020
Summary: Pathogenic bacteria secrete virulence factors that interact with the human host to establish infections. The human immune system evolved multiple mechanisms to fight bacterial invaders, including immune proteases that were demonstrated to ...

The Avirulence Domain of Cauliflower mosaic virus Transactivator/Viroplasmin Is a Determinant of Viral Virulence in Susceptible Hosts

open access: yesMolecular Plant-Microbe Interactions, 2004
Cauliflower mosaic virus (CaMV) transactivator/viroplasmin (Tav) is a multifunctional protein essential for basic replication of CaMV. It also plays a role in viral pathogenesis in crucifer and solanaceous host plants.

Erg25 Controls Host-Cholesterol Uptake Mediated by Aus1p-Associated Sterol-Rich Membrane Domains in Candida glabrata

open access: yesFrontiers in Cell and Developmental Biology, 2022
The uptake of cholesterol from the host is closely linked to the proliferation of pathogenic fungi and protozoa during infection. For some pathogenic fungi, cholesterol uptake is an important strategy for decreasing susceptibility to antifungals that ...

Mobilization, Cloning, and Sequence Determination of a Plasmid-Encoded Polygalacturonase from a Phytopathogenic Burkholderia (Pseudomonas) cepacia

open access: yesMolecular Plant-Microbe Interactions, 1997
Phytopathogenic strains of Burkholderia cepacia (synonym Pseudomonas cepacia) produce endopolygalacturonase, whereas strains of clinical and soil origin do not.

Virulence Factors in Coagulase-Negative Staphylococci [PDF]

open access: yesPathogens, 2021
Coagulase-negative staphylococci (CoNS) have emerged as major pathogens in healthcare-associated facilities, being S. epidermidis, S. haemolyticus and, more recently, S. lugdunensis, the most clinically relevant species. Despite being less virulent than the well-studied pathogen S.

Aspergillus fumigatus Fumagillin Contributes to Host Cell Damage

open access: yesJournal of Fungi, 2021
The activity of fumagillin, a mycotoxin produced by Aspergillus fumigatus, has not been studied in depth. In this study, we used a commercial fumagillin on cultures of two cell types (A549 pneumocytes and RAW 264.7 macrophages).

Special Issue “Sporothrix and Sporotrichosis 2.0”

open access: yesJournal of Fungi, 2022
Sporotrichosis is a chronic fungal disease of humans and other mammals that often affects the skin and subcutaneous tissues and, rarely, deep-seated organs (most frequently in immunocompetent hosts) [...]
