Imported African histoplasmosis by Histoplasma capsulatum var. duboisii in an H...

Objectives: African histoplasmosis caused by the fungus Histoplasma capsulatum var. duboisii, is a rare endemic mycosis occuring in western and central regions of sub-Saharian Africa. For unknown reasons, although HIV infection and H. capsulatum var. duboisii coexist in Africa, this coinfection remains rare. In Europe, diagnosed cases of African histoplasmosis are all imported. We describe a case of African his...

Screening of cryptic species among clinical Aspergillus isolates collected duri...

Objectives: Correct identification of Aspergillus species is important given that sibling species may show variable susceptibilities to multiple antifungal drugs and also because sharper definition of species may facilitate epidemiological studies. Thus, we screened Aspergillus clinical isolates from Portuguese hospitals to determine which, if any, of the cryptic species of Aspergillus were involved in patient ...

Contribuição para o controlo da infeção nosocomial de Candida parapsilosis por ...

Fungal infections constitute a relevant problem in hospitals from all over the world. Their easy transmission through the air, water, or by direct or indirect contact with contaminated persons, surfaces or objects lead to an increasing preoccupation with those infections, particularly in immunocompromised patients. Regarding the enormous importance of Candida parapsilosis as agent of bloodstream infections and ...

Pathogenic fungi: an unacknowledged risk at coastal resorts? New insights on mi...

Whilst the potential impact on beach users from microorganisms in water has received considerable attention, there has been relatively little investigation into microbial contaminants in sand. Thirty three beaches across Portugal were analyzed during a five year period (2006–2010) to determine the presence of yeasts, pathogenic fungi, dermatophytes, total coliforms, Escherichia coli and intestinal enterococci i...

Distribution of HCV genotypes among different exposure categories in Brazil

Hepatitis C virus (HCV) infection is widespread and responsible for more than 60% of chronic hepatitis cases. HCV presents a genetic variability which has led to viral classification into at least 6 genotypes and a series of subtypes. These variants present characteristic geographical distribution, but their association with different responses to treatment with interferon and severity of disease still remains ...
