Mucormycosis, an angioinvasive infection caused by the ubiquitous filamentous fungi of the order Mucorales and class Mucormycetes. Apophysomyces elegans (A. elegans) is one of the causative agents of mucormycosis. It causes rare but fatal outcomes. Despite that the infections are managed with surgical debridement followed by antifungal treatment, the resistance and toxicity issues have limited the use of existing antifungal agents, making it urgent to discover alternative treatments. As a well-trusted drug development partner staffed with a dedicated team of senior scientists, Creative Biolabs is here to help assist in your preclinical antifungal drug discovery and development projects.
Mucormycosis Caused by A.elegans
A. elegans has been a rather infrequent causative agent of mucormycosis compared to species of the genera Rhizopus, Absidia, and Rhizomucor. However, this fungus has increasingly been isolated from patients in tropical and subtropical climates over the last two decades. Patients from countries such as India, the southern USA, Australia, and Mexico have been documented. A. elegans was once believed to cause only cutaneous, subcutaneous, and soft tissue infections following trauma, burns, or invasive procedures in apparently healthy hosts, but it has been implicated in serious deep-seated infections (rhino-orbito-cerebral and renal mucormycosis) in recent years.

Susceptibility of A. elegans to Antifungal Drugs
Chakrabarti et al. (2010) reported the in vitro susceptibility testing of A. elegans to different antifungals. Amphotericin B displayed the best in vitro activity against the majority of zygomycetes, including A. elegans. However, limitations of amphotericin B exists, such as the toxicity. In brief, the number of therapeutic options against A. elegans is quite limited and the susceptibility is varied. As a result, there continues to be a need for developing new treatment strategies for mucormycosis caused by A. elegans.
