The late-arterial CT is superior to the porto-venous CT for initial diagnosis and follow-up of hepatic fungal infection. “
“Cryptococcosis has emerged as an important public health problem in Africa, Asia and the Americas due to the increasing numbers of persons at selleckchem risk of this infection and the adaptation of its aetiological agents to new environments. The proper management requires early recognition of Cryptococcus neoformans/C. gattii species complex infection, familiarity with the use and limitations of diagnostic tests and knowledge of the available treatment options. This review will address these issues with the goal of providing sufficient information to suspect, diagnose and
treat patients with cryptococcosis based on Cuban data and review of the literature. “
“The use of anti-fungal agents has increased dramatically in recent years and new drugs have been developed. Several methods are available for determinations of their
specific biological activities, i.e. the standard method for minimum inhibitory concentration-determination is described in M-38 [Clinical and Laboratory Standards Institute document M-38 (CLSI M-38)]. However, alternative methods, such as the E-test, are currently available in Mycology laboratories. The susceptibilities of clinical isolates of Aspergillus spp. (n = 29), Fusarium spp. (n = 5), zygomycetes (n = 21) and Schizophyllum (n = 1) were determined for itraconazole, voriconazole and posaconazole, using the CLSI M-38-A broth dilution method and also by the E-test. A good overall agreement Enzalutamide concentration (83.7%) between the two methods for all drugs and organisms was observed. Analyses of voriconazole showed a better agreement (93%) between the methods than posaconazole and itraconazole (85% and 74% respectively). Aspergillus spp. were the most susceptible fungi
to the anti-fungal agents tested in this study. Posaconazole was the most active drug against filamentous fungi in vitro, followed by itraconazole and voriconazole. The latter (voriconazole) demonstrated no significant in vitro activity against zygomycetes. “
“We Phospholipase D1 report on in vitro antifungal activity and the structure–activity relationship of diphenyl diselenide [(PhSe)2] and its synthetic analogues, (p-Cl-C6H4Se)2, (m-CF3-C6H4Se)2 and (p-CH3O-C6H4Se)2, against 116 strains of pathogenic fungi. (PhSe)2 showed the highest inhibitory activity against Candida albicans (minimum inhibitory concentration of 4–32 μg ml−1), Candida dubliniensis (2–16 μg ml−1), Aspergillus spp. (0.5–64 μg ml−1) and Fusarium spp. (2–16 μg ml−1). Its minimum fungicidal concentration (MFC) varied among C. albicans (4–64 μg ml−1), C. dubliniensis (2–32 μg ml−1) and Fusarium spp. (4–64 μg ml−1). Antifungal activity was decreased by the introduction of functional groups to the (PhSe)2 molecule: (PhSe)2 > (p-CH3O-C6H4Se)2 > (m-CF3-C6H4Se)2 > (p-Cl-C6H4Se)2. “
“Limited data are available on temporal and geographic variation of occurrence and antifungal resistance of non-C.
