Review of epidemiological data for onychomycosis caused by Aspergillus spp.

June 04 2018

A recent review of 42 epidemiological studies by Dr Felix Bongomin and colleagues showed that the causative agent of onychomycosis (nail infection) was Aspergillus spp. in 1-35% of cases overall, but more frequently among the elderly and those with diabetes (up to 71%). Toenails were affected 25x more often than fingernails.

New 3D model of squalene epoxidase may explain mechanism of terbinafine resistance

May 23 2018

Dermatophytes such as Trichophyton are commonly resistant to the allylamine antifungals (terbinafine, naftifine) used to treat them. Dr Rudramurthy and colleagues in India found that around 1 in 8 clinical isolates were resistant to these drugs, and 30% of them had a Phe397Leu mutation in squalene epoxidase. As this mutation sits in the enzyme's binding site, it is a plausible mechanism for resistance.
