Antigenic similarities to Paracoccidioides brasiliensis in thermo-dependent dimorphic fungi isolated from soil in Botucatu, SP, Brazil

NAT HIST MUSEUM & INST; Universidade Federal de São Paulo (UNIFESP); Universidade Estadual Paulista (Unesp) (Kluwer Academic Publ, 1997-01-01)

We compared the antigenic characteristics of two thermo-dependent dimorphic fungi isolated from soil in Botucatu, an endemic area of paracoccidioidomycosis (PCM) and Paracoccidioides brasiliensis. The soil isolates grew ...

Isolation of fungi from nature in the region of Botucatu, state of São Paulo, Brazil, an endemic area of paracoccidioidomycosis

Universidade Estadual Paulista (Unesp); Chiba University Research Center for Pathogenic Fungi and Microbial Toxicoses; Natural History Museum and Institute (Instituto Oswaldo Cruz, Ministério da Saúde, 1996-12-01)

In an attempt to isolate Paracoccidioides brasiliensis from nature 887 samples of soil from Botucatu, SP, Brazil, were collected cultured in brain heart infusion agar supplemented with dextrose, in potato dextrose agar and ...

A conserved dimorphism-regulating histidine kinase controls the dimorphic switching in Paracoccidioides brasiliensis

Chaves, Alison F. A. [UNIFESP]; Navarro, Marina V. [UNIFESP]; Castilho, Daniele G. [UNIFESP]; Calado, Juliana C. P. [UNIFESP]; Conceicao, Palloma M. [UNIFESP]; Batista, Wagner L. [UNIFESP] (Oxford Univ Press, 2016)

Paracoccidioides brasiliensis and P. lutzii, thermally dimorphic fungi, are the causative agents of paracoccidioidomycosis (PCM). Paracoccidioides infection occurs when conidia or mycelium fragments are inhaled by the host, ...

Phylogenetic and evolutionary aspects of Paracoccidioides brasiliensis reveal a long coexistence with animal hosts that explain several biological features of the pathogen

Universidade Estadual Paulista (Unesp); Universidade Federal de São Paulo (UNIFESP) (Elsevier B.V., 2006-09-01)

The habitat of the mycelial saprobic form of Paracoccidio ides brasiliensis, which produces the infectious propagula, has not been determined and has proven difficult for mycologists to describe. The fungus has been rarely ...

Evidence for the role of calcineurin in morphogenesis and calcium homeostasis during mycelium-to-yeast dimorphism of Paracoccidioides brasiliensis

Universidade do Vale do Paraiba (UNIVAP); City University of New York; Universidade Estadual Paulista (Unesp) (2008-10-01)

Paracoccidioides brasiliensis is a dimorphic fungus that causes paracoccidioidomycosis, the most prevalent human deep mycosis in Latin America. The dimorphic transition from mycelium to yeast (M-Y) is triggered by a ...

Linear epitopes of Paracoccidioides brasiliensis and Other Fungal Agents of Human Systemic Mycoses As vaccine Candidates

Travassos, Luiz R. [UNIFESP]; Taborda, Carlos P. [UNIFESP] (Frontiers Media Sa, 2017)

Dimorphic fungi are agents of systemic mycoses associated with significant morbidity and frequent lethality in the Americas. Among the pathogenic species are Paracoccidioides brasiliensis and Paracoccidioides lutzii, which ...

Fungi that Infect Humans

Kohler, Julia R.; Hube, Bernhard; Puccia, Rosana [UNIFESP]; Casadevall, Arturo; Perfect, John R. (Amer Soc Microbiology, 2017)

Fungi must meet four criteria to infect humans: growth at human body temperatures, circumvention or penetration of surface barriers, lysis and absorption of tissue, and resistance to immune defenses, including elevated ...

Ciprofloxacin shows synergism with classical antifungals against Histoplasma capsulatum var. capsulatum and Coccidioides posadasii

Brilhante, R. S. N.; Caetano, E. P.; Sidrim, J. J. C.; Cordeiro, R. A.; Camargo, Z. P. [UNIFESP]; Fechine, M. A. B.; Lima, R. A. C.; Castelo Branco, D. S. C. M.; Marques, F. J. F.; Mesquita, J. R. L.; Lima, D. T.; Monteiro, A. J.; Rocha, M. F. G. (Wiley-Blackwell, 2013-05-01)

This study evaluated the in vitro interaction between ciprofloxacin (CIP) and classical antifungals against Histoplasma capsulatum var. capsulatum in mycelial (n=16) and yeast-like forms (n=9) and Coccidioides posadasii ...

Reversion by calcium of a yeast-like development to the original filamentous form, of the 10V10 5-fluorocytosine-sensitive mutant of Aspergillus niger

Universidade Estadual Paulista (Unesp); Universidade de São Paulo (USP) (Sociedade Brasileira de Microbiologia, 2005-09-01)

Alguns fungos filamentosos apresentam o fenômeno de dimorfismo, sendo que as alterações da estrutura morfológica podem induzir alterações metabólicas. A linhagem de Aspergillus niger 10v10, produtora de ácido cítrico foi ...

Dual localization of Mdj1 in pathogenic fungi varies with growth temperature

Dourado, Itala Bruna Z. [UNIFESP]; Batista, Wagner L. [UNIFESP]; Longo, Larissa V. G. [UNIFESP]; Mortara, Renato A. [UNIFESP]; Puccia, Rosana [UNIFESP] (Informa Healthcare, 2014-02-01)

Paracoccidioides brasiliensis and P. lutzii are temperature-dependent dimorphic fungi that cause paracoccidioidomycosis (PCM). Previously, we characterized the PbMDJ1 gene. This gene encodes P. brasiliensis chaperone Mdj1, ...
