Abstract

A new azole resistance mechanism in Aspergillus fumigatus consisting of a TR46/Y121F/T289A alteration in the cyp51A gene was recently described in the Netherlands. Strains containing these mutations are associated with invasive infection and therapy failure. This communication describes the first case of fatal invasive aspergillosis caused by TR46/Y121F/T289A outside the Netherlands, in the neighboring country of Belgium, suggesting geographical spread. TR46/Y121F/T289A leads to a recognisable phenotypic susceptibility pattern which should trigger cyp51A genotyping to monitor further spread.
