Se utilizaron las infusiones naturales de las variedades Solanum tuberosum (papa blanca), Solanum
chaucha (papa huayro) y Solanum goniocalyx (papa amarilla), para preparar los medios de cultivo análogos al estándar de
formulación comercial Agar Papa Dextrosa (APDc). Las cepas de T. rubrum fueron inoculadas en los diferentes medios de cultivo, incubados a 2°C durante 10 días.
Para la evaluación consideramos características culturales y microscópicas. Los resultados muestran que el medio de cultivo Agar Papa Huayro Dextrosa (APHD) fue más eficiente en la producción del pigmento rojo vino, pero se obtuvo mayor esporulación en los medios de cultivo Agar Papa Blanca Dextrosa (APBD) y Agar Papa Amarilla Dextrosa (APAD)

SUMMARY
The objective of this study was demonstrate the efficacy of three potato varieties to identify Trichophyton rubrum and to
suggest their for diagnosing dermatomycoses . White potato (Solanum tuberosum), Huayro potato (Solanum chaucha)
and Yellow potatoe (Solanum goniocalyx) extracts were used to prepare similar culture media to be compared with standard
and commercial APDc. T. rubrum strains were innoculated in the three culture media and they were incubated at
2°C for 10 days. Culture and microbiological characteristics were used for evaluation purposes. The results showed that APHD
culture medium was more efficient in producing red wine pigment compared to the other potato varieties; but more
sporulation was achieved using APBD and APAD culture media.
