چکیده
Sporotrichosis is a chronic fungal disease usually limited to cutaneous and subcutaneous tissues. The most common way of the infection is the skin trauma by a prick from a thorn or a piece from a variety of barks, trees and bushes. Occupations that predispose persons to infections includes: farmer-agriculturist, gardener, florist, planters of trees, forestry workers, horticulturist, workers of the greenhouses, orchids growers, outdoor labor, masonry, veterinarians and laboratory workers (microbiologist), and people involved in activities and exposure to contaminated soils, vegetations, wood, sphagnum moss, wheat, straw, prairie hay, corn husks and strubble, barks, thorny plants and shrubs, reeds, rose bushes, cat ́s skin ulcers, rodent bites and punctures of insects. A critical review of published epidemics and the mechanisms of zoonotic cat ́s transmitted infection, and the recent advances were also described. Resumen La esporotricosis es una enfermedad micótica crónica, generalmente está limitada en los tejidos cutáneos y subcutáneos. La forma más común de la infección es el trauma de la piel, ocasionado por el pinchazo de una espina o de un fragmento de gran variedad de cortezas de árboles y arbustos. Las personas predispuestas a las infecciones incluyen: campesinos, jardineros, floristas, plantadores de árboles, trabajadores de la silvicultura, horticultores, trabajadores de los invernaderos, cultivadores de orquídeas, sujetos con trabajo al aire libre, albañiles, veterinarios y técnicos de laboratorio (microbiólogo), así como la gente implicada en actividades con exposición a suelos contaminados, vegetales, madera, musgo de Sphagnum, paja del trigo, heno de la pradera, hojas de maíz y puntas de rastrojo, cortezas, plantas y arbustos espinosos, cañas, rosales con espinas, y personas expuestas a úlceras en la piel de los gatos, mordeduras de roedores y picaduras de insectos. Este artículo presenta una revisión crítica de las epidemias publicadas, los mecanismos de transmisión zoonótica de la infección felina y los avances recientes. www.medigraphic.org.mx

Although sporotrichosis is not an AIDS-defining infection, reports of sporotrichosis in individuals infected with HIV are increasing. We report an unusual case of this co-infection in a man with progressive deep cutaneous ulcerations with numerous pleomorphic yeast cells of Sporothrix schenckii. In addition a review of the literature on this subject was carried out and commented upon.

Sporothrix schenckii, previously assumed to be the sole agent of human and animal sporotrichosis, is in fact a species complex. Recently recognized taxa include S. brasiliensis, S. globosa, S. mexicana, and S. luriei, in addition to S. schenckii sensu stricto. Over the last decades, large epidemics of sporotrichosis occurred in Brazil due to zoonotic transmission, and cats were pointed out as k...
