Trichophyton rubrum remains the most common cause of toenail fungus in the United States, but nondermatophyte molds--Scopulariopsis, Fusarium, and others--are on the rise, so it's important to speciate, especially when patients have atypical presentations or fail to respond to the T. rubrum
go-to treatment, terbinafine, according to Nathaniel Jellinek, MD, of the department of dermatology, Brown University, Providence, R.I.
Trichophyton was the predominant genus among the three genera of dermatophytes in our study which concurs the observation in previous studies performed worldwide.23,24 T. rubrum
is the main dermatophyte reported from India and other countries.4 Contrast to the most studies, a study carried out between 2004 and 2006 in Qazvin, Iran showed Epidermophyton floccosum as the most frequently isolated species representing 32.8% of isolates, followed by T.
An appropriate model constructed to simulate host infection is the prerequisite to study the pathogenesis of dermatophytosis caused by T. rubrum
. In this study, we intended to develop a new T.
Ghannoum found that risk factors for spread included infection with Trichophyton rubrum (six times the odds ratio), infection with T. rubrum
strain types B or D (nine times the odds ratio), a past history of infection (five times the odds ratio), and plantar scaling (four times the odds ratio).
Efinaconazole has demonstrated effectiveness as a topical treatment for T. rubrum
, but treatment can be expensive, wrote Caroline B.
Therefore, this research aimed to analyze whether the culture supernatant derived from T. rubrum
grown in the nail medium could elicit the immune response of keratinocyte effectively.
Regarding the causative pathogen and the clinical type of onychomycosis (Table 4), T. rubrum
was isolated from all types of onychomycosis i.e.
Gupta and his associates examined 50 adults who were infected with T. rubrum
, determined via analysis of toenail specimens from onychomycosis patients in southwest Ontario.
