Pathogenicity and Distribution: Trichophyton tonsurans is a cosmopolitan (found worldwide) dermatophyte (a fungus of skin, nails or hair). It is the etiologic agent most frequently implicated in âringwormâ infections of the scalp (Tinea capitis) in America. Causes an endothrix infection of the hair (penetrates hair shaft to grow within). T.tonsurans is anthropophilic (prefers humans to animals) however sources vary on its infectivity.
The Solanaceae, or nightshades, are an economically important family of flowering plants. The family ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of important agricultural crops, medicinal plants, spices, weeds, and ornamentals.
The tomato plant (Solanum lycopersicum) is a herbaceous plant that is part of the nightshade family. The plant is commonly grown all over the world for its fruit, the tomato. Though botanically classified as fruits, many people think of them as being garden vegetables due to their savory taste.
