Fusarium keratoplasticum

STRUCTURE AND PHYSIOLOGY

F. keratoplasticum is a filamentous fungi. Research has indicated that the hyphae and chlamydospores of F. keratoplasticum can produce melanin in-vitro and the hyphae can produce pigment in-vivo.

TRANSMISSION AND DISEASE

F. keratoplasticum can cause a broad spectrum of infections based on how the fungi are introduced to the host. The infections in non-immunocompromised people tend to be non-threatening and localized, whilst in immunocompromised people, the infection can lead to death.

DISINFECTION

Species of the Fusarium genus can create biofilms, which can make them more challenging to disinfect.

NOTES

The Fusarium genus shows resistance to most antifungal agents, which can make it difficult to treat. F. keratoplasticum is also the most common biofilm found in plumbing.
