The cytolytic peptide Candidalysin is produced during hyphal formation by Candida albicans; it is an example of a virulence factor from a fungus. Other virulence factors include factors required for biofilm formation (e.g. sortases) and integrins (e.g. beta-1 and 3). [7]

Virulence is a pathogen's or microorganism's ability to cause damage to a host. In most cases, especially in animal systems, virulence refers to the degree of damage caused by a microbe to its host. [1] The pathogenicity of an organism—its ability to cause disease—is determined by its virulence factors.
Genes that satisfy molecular Koch's postulates are often referred to as virulence factors. The postulates were formulated by the microbiologist Stanley Falkow in 1988 and are based on Koch's postulates. [1]
In other words, different virus strains possessing different virus factors can lead to different degrees of virulence, which in turn can be exploited to study the differences in pathogenesis of viral variants with different virulence. [10] [11] Virus factors are largely influenced by viral genetics, which is the virulence determinant of ...
VFDB also known as Virulence Factor Database is a database that provides scientist quick access to virulence factors in bacterial pathogens. [1] It can be navigated and browsed using genus or words. A BLAST tool is provided for search against known virulence factors. [2] VFDB contains a collection of 16 important bacterial pathogens. [1]
Bacterial adhesins are cell-surface components or appendages of bacteria that facilitate adhesion or adherence to other cells or to surfaces, usually in the host they are infecting or living in. Adhesins are a type of virulence factor. Adherence is an essential step in bacterial pathogenesis or infection, required for colonizing a new host. [1]
In 1988, microbiologist Stanley Falkow developed a set of three Molecular Koch's postulates for identifying the microbial genes encoding virulence factors. First, the phenotype of a disease symptom must be associated with a specific genotype only found in pathogenic strains. Second, that symptom should not be present when the associated gene is ...
