Antifungal susceptibility of Aspergillus fumigatus clinical isolates collected from various areas in Japan.

Azole resistance among clinical isolates of Aspergillus fumigatus is becoming a serious problem in Europe, but the status in Japan is not yet known in detail. The aim of this study was to determine the present status of azole resistance in A. fumigatus in Japan.

[Fungicidal activity of liranaftate against dermatophytes].

The fungicidal activities of the thiocarbamate antifungal agent liranaftate were compared to those of luliconazole, amorolfine hydrochloride and ketoconazole against twelve stock strains of three species of dermatophytes. The MICs of 0.001-0.

Antimicrobial activity of hydrophobic xanthones from Cudrania cochinchinensis against Bacillus subtilis and methicillin-resistant Staphylococcus aureus.

Ten xanthones with one or two isoprenoid groups and a prenylated benzophenone isolated from roots of Cudrania cochinchinensis (Moraceae) were tested for their antimicrobial activities against Bacillus subtilis and methicillin-resistant Staphylococcus aureus (MRSA). Among these compounds, gerontoxanthone H exhibited considerable antibacterial activity against B. subtilis (MIC = 1.

Antimicrobial activities of hydrophobic 2-arylbenzofurans and an isoflavone against vancomycin-resistant enterococci and methicillin-resistant Staphylococcus aureus.

Eight 2-arylbenzofurans and an isoflavone isolated from medicinal plants were tested for their antimicrobial activities against vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA). Among these compounds, six hydrophobic 2-arylbenzofurans (log P = 4.4-8.

[Fungicidal activity of liranaftate against Trichophyton rubrum].

The fungicidal activities of thiocarbamate antifungal agent liranaftate were studied by determining the MIC and the MCC against Trichophyton rubrum with the Milliflex -100 Test System and by determining the time-kill curve in comparison to that of six reference agents. Liranaftate and lanoconazole both showed excellent fungistatic activity against the conidia of T. rubrum.
