What is Trichophyton mentagrophytes in humans?
Trichophyton mentagrophytes is primarily a zoophilic dermatophyte that often attacks humans and may also survive saprophytically in the soil. From: Diagnostic Procedure in Veterinary Bacteriology and Mycology (Fifth Edition), 1990.
Where are Trichophyton mentagrophytes from?
Trichophyton mentagrophytes is being frequently isolated from dogs, cats, rabbits, guinea pigs and other rodents, though at least some genetic variants possess the potential of human-to-human transmission, e.g. Type VII and Type VIII. Particular genetic variants of the fungus have distinct geographic ranges.
What is the characteristics of Trichophyton mentagrophytes?
Colonies of T. mentagrophytes are generally characterized by flat, white to cream in color, with a powdery to the granular surface. Reverse pigmentation is usually a yellow-brown to reddish-brown color. Some cultures show central folding or develop raised central tufts or pleomorphic suede-like to downy areas.
How can you tell if you have Trichophyton mentagrophytes?
Trichophyton mentagrophytes is the most common fungal agent of mice. However, infection rarely causes clinical disease. Clinical signs include sparse hair coats or well-demarcated crusty lesions, with a chalky surface on the head, tail, and legs (favus or ringworm).
How do you treat Trichophyton mentagrophytes?
Tinea must be treated systemically and topically because of infectivity and ignitability. Systemic terbinafine or fluconazole treatment and topical fixed combination isoconazole nitrate/diflucortolone valerate are recommended.
What kills Trichophyton mentagrophytes?
Ozone gas effectively kills laboratory strains of Trichophyton rubrum and Trichophyton mentagrophytes using an in vitro test system. J Dermatolog Treat.
Is Trichophyton contagious?
Abstract. Trichophytia infection, paraphrased cuddly toy mycosis, occurs primarily in prepubertal children, occasionally in infants and adults. The presented case shows the highly contagious infection of four family members with Trichophyton mentagrophytes.
How is Trichophyton treated?
Treatment of Tinea Capitis
The most common etiological agent reported is Trichophyton species. Treatment with oral terbinafine, itraconazole, and griseofulvin has been used with good efficacy. Terbinafine 250 mg daily for 2–4 weeks may be preferred over itraconazole and griseofulvin in patients on multiple drugs.
What are the symptoms of Trichophyton?
How does Trichophyton enter the body?
They can be transmitted by direct contact, by contact with infested particles (of dead skin, nails, hair) shed by the host, and by contact with the fungi’s spores.
How is Trichophyton mentagrophytes transmitted?
mentagrophytes with four different DNA markers. While human-to-human transmission of zoophilic dermatophytes is rare, transmission via sexual contact seemed to be quite effective here.
