Does concomitant bacteraemia hide the fungi in blood cultures? An in vitro study.

Polymicrobial infections including yeasts and bacteria are not rare and patients with polymicrobial bloodstream infection have higher early and overall case fatality rates. The diagnosis of invasive fungal and bacterial infections is mainly based on blood culture. The aim was to reveal the effect of concomitant bacteraemia on the detection of fungi from blood cultures in the presence of polymicrobial bloodstream infections involving and non- fungi and to show the superiority of blood culture bottles including selective fungal media in such situations.
