Etymology for page Handroanthus heptaphyllus

[edit]

Its tribe name, "Tecomeae", is derived from its Brazilian vernacular name: tabebuia or taiaveruia. Its species name, "heptaphyllus", is derived from the Greek prefixes "hepta" and "phyllon" meaning "seven" and "leaf" respectively.

Virulence

[edit]

Pili are responsible for virulence in the pathogenic strains of many species of bacteria including E. coli, Vibrio cholerae, and many strains of Streptococcus among others.[1][2] This is because the presence of pili greatly enhance bacteria's ability to bind to body tissues, which then increases replication rates and ability to interact with the host organism.[1] If a species of bacteria has multiple strains but only some are pathogenic, it is likely that the pathogenic strains will have pili while the nonpathogenic strains won't. [3][4]

These attachment pili may then result in the development of further virulence traits. V. cholerae first evolved pili, allowing it to bind to human tissues and form microcolonies. [1][4] The pilus then served as a binding site for a lysogenic bacteriophage (CTXɸ) that carries the disease-causing toxin. [1][4] The gene for this toxin, once incorporated into the bacterium's genome, is expressed when the gene coding for the pilus is expressed (hence the name "toxin mediated pilus").[1]
