Azoles are the mainstay of oral therapy for aspergillosis. Azole resistance in Aspergillus has been reported infrequently. The first resistant isolate was detected in 1999 in Manchester, UK. In a clinical collection of 519 A. fumigatus isolates, the frequency of itraconazole resistance was 5%, a significant increase since 2004 (p<0.001). Of the 34(More)
Invasive fungal infections cause significant morbidity and mortality in patients with concomitant underlying immunosuppressive diseases. The recent addition of new triazoles to the antifungal armamentarium has allowed for extended-spectrum activity and flexibility of administration. Over the years, clinical use has raised concerns about the degree of drug(More)
Acute encephalitis caused by Toxoplasma gondii was diagnosed in ten patients in Belgium, the U.S.A., and Canada. None had underlying conditions usually associated with toxoplasmosis. Three had evidence of extraneural infection at necropsy. Nine patients died. Only two of the patients had a history of homosexuality, and one was a heroin addict. Five were(More)
Penicillin--"tolerant" Staphylococcus aureus strains are resistant to the lethal action of penicillins, but are inhibited by normal (low) concentrations. They are deficient in autolytic enzyme activity which appears to be necessary for bacteriolysis and the lethal action of penicillins. This "deficiency" is caused by a large excess of an inhibitor of(More)
A 22 year-old man died from multiple cerebral abscesses due to Petriellidium boydii 4 1/2 months after an episode of near drowning. The autopsy showed dissemination to heart and kidney. This patient had no immunocompromising disease but was treated with corticosteroids. The treatment of this condition with ventricular shunting and amphotericin B is(More)
