Beauveria bassiana is an environmentally friendly alternative to chemical insecticides against various agricultural insect pests and vectors of human diseases. However, its application has been limited due to slow kill and sensitivity to abiotic stresses. Understanding of the molecular pathogenesis and physiological characteristics would facilitate improvement of the fungal performance. Loss-of...
Most factors known to function in mRNA turnover are not essential for cell viability. To identify essential factors, approximately 4000 temperature-sensitive yeast strains were screened for an increase in the level of the unstable CYH2 pre-mRNA. At the non-permissive temperature, five mutants exhibited decreased decay rates of the CYH2 pre-mRNA and mRNA, and the STE2, URA5 and PAB1 mRNAs. Of th...
زمینه و هدف: کریپتوکوکوس نئوفورمنس بیشتر افراد دچار نقص سیستم ایمنی را درگیر میکند و مننژیت حالت شایع بیماری میباشد. روشهای متعددی برای تشخیص این عامل کشنده رایج است اما هیچکدام از این روشها، حساسیت، اختصاصیت و سرعت قابل قبولی را ندارند. LAMP یک روش مقرون بهصرفه در عین حال بسیار سریع و حساس و سودمند بهویژه در کشورهای در حال توسعه میباشد. در این مطالعه سعی بر ...

In order to study the infectious agents causing human disseminated cryptococcosis in the state of Pará, North Brazil, 56 isolates of Cryptococcusspp. (54 isolated from cerebral spinal fluid and two from blood cultures) from 43 cases diagnosed between 2003-2007 were analysed. The species were determined through morphological and physiological tests and genotypes were determined by URA5-RFLP and ...
Cryptococcal infection is transmitted by the inhalation of Cryptococcus spp. propagules. Information about the Cryptococcus species inhabiting plants might be clinically relevant due to the epidemiological role of these habitats as possible sources of human infection. The aim of this study was to increase the knowledge about the environmental occurrence of cryptococcosis agents. Hollow tree veg...
The molecular types of 443 Brazilian isolates of Cryptococcus neoformans and Cryptococcus gattii were analyzed to determine their geographic distribution within Brazil and their underlying host conditions. The following data, imported from previous epidemiological studies as well as two culture collections, were analyzed for: place of isolation, source (clinical or environmental), host risk fac...
INTRODUCTION In Cúcuta, Cryptococcus gattii serotype B is commonly recovered from immunocompetent patients with cryptococcosis, but it has not been recovered from the environment in spite of its high incidence which is 77% out of reported cases. OBJECTIVE The aim of this work was to carry out an extensive environmental sampling in Cúcuta, in an attempt to isolate C. gattii serotype B and to e...
Cryptococcosis is a human fungal infection of significant mortality and morbidity, especially in the meningoencephalitis form. Cryptococcosis is distributed worldwide and its agents, C. neoformans and C. gattii, present eight major molecular types-VNI-VNIV and VGI-VGIV respectively. The primary cryptococcosis caused by molecular type VGII (serotype B, MAT alpha) prevails in immunocompetent pati...
INTRODUCTION Cryptococcosis is a systemic fungal infection that affects humans and animals, mainly due to Cryptococcus neoformans and Cryptococcus gattii. Following the epidemic of acquired immunodeficiency syndrome (AIDS), fungal infections by C. neoformans have become more common among immunocompromised patients. Cryptococcus gattii has primarily been isolated as a primary pathogen in healthy...
