“…107 (7): 854-858, November 2012 The term phaeohyphomycosis (from the Greek phaios, meaning dark or darkish) was introduced by Ajello et al in 1974 to designate infections by phaeoid or pigmented filamentous fungi that contain melanin in their walls. These microorganisms are saprobes in nature, found in wood and decomposing plants.…”

“…Phaeoacremonium Ajello et al [14] showed cardinal temperatures for P. parasiticum growth as 15˚C (minimum), 25˚C (optimum), and 35˚C (maximum). The other study suggested that discrepant optimal growth temperatures have been obtained for P. parasiticum, ranging from 25˚C -30˚C and the optimum was closer to 30˚ than to 25˚C [15].…”

For establishing the favourable media for growth of Phaeoacremonium parasiticum, the fungus was inoculated in five different media (Potato Dextrose Broth (PDB), Host Extract (50%) + PDB (50%) (HE + PDB), and the solid media viz., Rice Bran (RB), Maize Meal (MM) and Wheat Bran (WB)) at pH of 6.5 and incubated at a temperature of 30˚C ± 1˚C. The solid media were added with water at the rate of 70 ml/100g of solid substrate. After 30 days of inoculation, conidial population of P. parasiticum in liquid media was lower compared to conidial population in solid media. In solid media, MM media showed the highest conidial population (9.56 log•cfu/g) followed by WB (9.50 log•cfu/g) and RB (9.38 log•cfu/g). Hence, Maize Meal media (MM: Water = 100 g:70 ml) at pH of 6.5, incubation temperature: 30˚C ± 1˚C for 30 days would be the standard technique for mass production of P. parasiticum.

“…El término feohifomicosis (derivado del griego phaios "negro" u "´oscuro", y mykes "hongos") fue acuñado en 1974 por Ajello et al (5), posteriormente fue aceptado por la International Society for Human and Animal Mycology (ISHAM). Banti describie la enfermedad en Italia en 1911 cuando encontró en una necropsia "múltiples nódulos que parecían un sarcoma melanótico".…”

“…Posteriormente, el hongo fue clasificado por Saccardo como Torula bantiana (2). En 1952, en Estados Unidos, se describió un caso con absceso cerebral del que se aisló una masa de hifas pigmentadas, inicialmente clasificado por Emmons como Cladosporium trichoides (6), pero en 1960 Borelli lo reclasificó como Cladosporium bantianum (5,2).…”

ResumenLas feohifomicosis comprenden un grupo de infecciones causadas por hongos pigmentados, negros o dematiáceos. En las últimas dos décadas se ha incrementado la frecuencia de reportes y la diversidad de los agentes etiológicos implicados, especialmente en los individuos inmunosuprimidos. Los principales géneros involucrados incluyen Alternaria, Bipolaris, Cladophialophora y Exophiala. Estos hongos típicamente se encuentran en el suelo y son introducidos al cuerpo a través de la inhalación o el trauma. El espectro de las enfermedades asociadas también se ha ampliado e incluye infecciones cutáneas superficiales y profundas, enfermedad alérgica, neumonía, abscesos cerebrales e infección diseminada. El diagnóstico de laboratorio está basado en las características morfológicas de los agentes según lo observado en el examen microscópico directo y la histopatología. El tratamiento es a menudo difícil y depende del síndrome clínico. No hay terapias estandarizadas, pero voriconazol, posaconazol e itraconazol han demostrado la actividad in vitro más consistente contra este grupo de hongos. La rareza de estas micosis justifica describir las características clínicas, epidemiológicas y diagnósticas para ayudar a un reconocimiento inmediato y un tratamiento oportuno.Palabras clave: Feohifomicosis, Dematiáceos, Feohifomicosis subcutánea, Infecciones oportunistas, Agentes antifúngicos. AbstractPhaeohyphomycosis comprises a group of infections caused by black pigmented or dematiaceous fungi. In the last two decades the frequency of reporting and diversity of etiologic agents involved have increased, especially in immunosuppressed individuals. The main genera involved include Alternaria, Bipolaris, Cladophialophora and Exophiala. These fungi are typically found in the soil and introduced through inhalation or trauma. The spectrum of associated diseases also has broadened and includes superficial and deep cutaneous infections, allergic disease, pneumonia, brain abscess and disseminated infection. The laboratory diagnosis is based on the morphological characteristics of the agents as observed by direct microscopic examination and histopathology. Treatment is often challenging and depends upon
