The significance of routine blood culture for the diagnosis of deep-seated fungal infection was evaluated in 34 patients in whom fungi were detected by routine blood sultures and 1404 cases in whom blood cultures were obtained at autopsy during the past 11 years. The sites of fungal infection were confirmed in 24(63%) of 38 occasions of fungemia on routine blood culture in 34 patients, but not in the remaining 14(37%). Fungemia was found by postomortem blood culture in 35 of 1404 autopised cases
