Basidiobolus haptosporus

[7] Morphological and physiological features of Basidiobolus species vary based on environmental conditions, and as such there has been much controversy surrounding the naming and methods of interspecies differentiation within the genus.

[3] Cultures of B. haptosporus grown on Sabouraud dextrose agar (SDA) plates have shown a growth habit of creating grey, smooth, flat, and glabrous colonies without the presence of obvious aerial hyphae or the musty Streptomyces-like odor typically associated with other Basidiobolus species.

[2][3] As the B. haptosporus cultures age on the SDA plates (5–6 days post-subculturing), the colony becomes a pale yellow color with radially folded hyphae, reaching a diameter of approximately 1–2 cm.

[1] Basidiobolus species occur mainly within tropical and subtropical regions and have generally been associated with the gastrointestinal tract of amphibians, but are also found in reptiles, other animals and insects, soil, and plant detritus.

[4] Gastrointestinal mycosis tends to present with typical stomach and colon disease symptoms, including abdominal pain, fever, heavy sweating, and diarrhea.

[2] Management of these diseases is typically treated with common antifungal therapies including potassium iodide (KI), amphotericin B, itraconazole, and ketoconazole, and surgery.

[7] It is hypothesized that the use of "toilet leaves" is a potential source of infections in humans, as the soil and vegetation could be contaminated by the fecal matter of amphibians and reptiles.
