[1] It has a worldwide distribution, however human infection is more common in rural areas where contact with animals is more frequent, and can cause severe inflammation of the afflicted region.

[4] In culture, it is characterized by being flat, white/cream colour, having an occasional dome, with a glabrous texture, known as the variant album, however other variations are also found: T. verrucosum var.

[5][6] Under a microscope, macronidia are rare, and have a rat-tail or string bean shape, while micronidia are tear-shaped and have been only observed in laboratories when grown under enriched conditions.

[6] Trichophyton verrucosum is thought to have evolved from a soil-dwelling ancestor that migrated to its contemporary cattle host, losing many features that it previously required for survival in soil habitats through genetic drift, including vitamin prototrophy, urease activity, and the ability to perforate hair.

[13] The LTF-130 vaccine was developed in the early 1970s by a team led by Lyubov Yablochnik and A. K. Sarkisov at the All-Russian Scientific Research Institute of Experimental Veterinary Medicine.

[17][18] In preparing samples for diagnosis, a scraping of the skin from the active border of infection is taken, and is inoculated directly onto the test medium.

[1] In Bromocresol purple (BCP) milk solids glucose agar, a medium used to distinguish the dermatophytes from bacteria and other organisms by evaluating ammonium production during proteolysis, T. verrucosum produces a weakly alkaline result (faint purple) and clearing of milk solids with a characteristic halo on the periphery.

[16] Indeed, one study found that people infected with T. verrucosum had to visit a physician on average of 2.5 times, with 25 days elapsing, before a proper diagnosis was obtained.

[20] This may lead to an underestimation of the true number of cases, as many people will recover from the disease before obtaining a proper diagnosis.
