RESUMEN
Pythiosis is caused due to a filamentous eukaryotic micro-organism called Pythium insidiosum and the disease occurs commonly in horses and cattle. Subcutaneous pythiosis infection in humans is rare with no clear clinical guidelines for treatment. We present a case of a man in his 20s with non-resolving ulcers noted over lower extremity after exposure to swamp water draining animal remains. The patient received several courses of oral antibiotics with no improvement in symptoms before getting admitted to our institution. A diagnosis of subcutaneous pythiosis was made after deep wound culture following debridement detected P. insidiosum by use of PCR. Due to the rare incidence of such infection in humans and no clear guidelines available for treatment, the case was discussed with infectious disease specialists outside our institution and with veterinary physicians. An emergent approval for use of immunotherapy in conjunction with surgical debridement and antimicrobials was obtained from Food and Drug administration. The patient underwent successful treatment of infection and skin graft following treatment.

We describe the first reported case of acute respiratory distress syndrome (ARDS) attributed to Neosartorya udagawae infection. This mold grew rapidly in cultures of multiple respiratory specimens from a previously healthy 43-year-old woman. Neosartorya spp. are a recently recognized cause of invasive disease in immunocompromised patients that can be mistaken for their sexual teleomorph, Aspergillus fumigatus. Because the cultures were sterile, phenotypic identification was not possible. DNA sequencing of ITS, calmodulin and ß-tubulin genes supported identification of Neosartorya udagawae. Our case is the first report of ARDS associated with Neosartorya sp. infection and defines a new clinical entity.
