Cryptococcus neoformans is encapsulated yeast, which is highly prevalent in the soil. animals and as a colonist in humans. The most important event involved in host defense against Cryptococcus neoformans is the development of an adequate cell-mediated immune response particularly T cell mediated immunity. The level of immunity caq cause the spectrum to vary from mere colonization of the respir...

Cryptococcus neoformans colonies can be identified within 6 h using paper disks containing caffeic acid and ferric citrate. Indentification is based on the development of a dark brown pigment. Saprophytic Cryptococcus species and common clinically isolated yeasts do not develop the brown color. The concentration of the reagents and the method of storage of the impregnated paper disks are critic...

Disseminated infection with Cryptococcus neoformans was observed in a newborn infant who presented fever and respiratory symptoms since the 52 day of life. The mother was infected by human immunodeficiency virus and presented pulmonary and meningeal cryptococcal infection. This is a rare case of cryptococcal infection with probable maternal-fetal transmission. Key-words: Cryptococcus neoformans...

Increase in cryptococcal infection has been noticed after acquired immunodeficiency syndrome pandemic. Cryptococcus neoformans can be isolated from blood in the process of dissemination to brain. We report a case of cryptococcal fungaemia in a patient whose cerebrospinal fluid was negative for Cryptococcus neoformans. Retrospective analysis revealed human immunodeficiency virus seropositivity o...

More than 110 years of study of the Cryptococcus neoformans and Cryptococcus gattii species complex has resulted in an enormous accumulation of fundamental and applied biological and clinical knowledge. Recent developments in our understanding of the diversity within the species complex are presented, emphasizing the intraspecific complexity, which includes species, microspecies, hybrids, serot...

(57) ABSTRACT Disclosed are methods of identifying subspecies of Crypto coccus flavescens and methods of treating or suppressing Fusarium head blight with the different Cryptococcus flave scens species. In particular, two genotypes, Genotypes A and B, were identified using the disclosed real time PCR tech nique. The following Cryptococcus flavescens strains were identified as being either Genot...

Cryptococcosis is a fungal infection caused by Cryptococcus neoformans and Cryptococcus gandii. The encapsulated organisms are inhaled and survive in the respiratory tract without causing any harm. However, depending upon the immunity of the individual, it may result in several clinical diseases. Cryptococcosis is therefore known as an opportunistic infection. Patients with immune deficiency su...
