25. Validation and clinical application of a nested PCR for paracoccidioidomycosis diagnosis in clinical samples from Colombian patients
Paracoccidioidomycosis is a systemic and endemic mycosis, restricted to tropical and subtropical areas of Latin America. The infection is caused by the thermal dimorphic fungus Paracoccidioides brasiliensisand Paracoccidioides lutzii. The diagnosis of paracoccidioidomycosis is usually performed by microscopic examination, culture and immunodiagnostic tests t

26. Influence of the Paracoccidioides brasiliensis14-3-3 and gp43 proteins on the induction of apoptosis in A549 epithelial cells
The fungal strain Paracoccidioides brasiliensisremains viable inside of epithelial cells and can induce apoptosis in this population. However, until now, the molecules that participate in this process remained unknown. Thus, this study evaluated the contribution of two P. brasiliensismolecules, the 14-3-3 and glycoprotein of 43 kDa proteins, which had been p

27. Seroepidemiology of Paracoccidioides brasiliensis infection in horses from Rio Grande do Sul, Brazil
Paracoccidioides brasiliensis is the etiological agent of the major systemic mycosis in Brazil, called paracoccidioidomycosis. Although the Rio Grande do Sul is considered an endemic area of the disease, there are few studies on the ecology of P. brasiliensis in the state. Therefore, this study aimed to evaluate the infection of P. brasiliensis in horses fro

28. Importance of the association of molecular and immunological diagnosis in immunocompetent patient with Histoplasma capsulatum and Cryptoccocus neoformans infection: a case report
This case reports an immunocompetent 29-year-old woman with suspected pneumonia, suggestive of fungal infection. Immunoblotting analysis reactivity against Histoplasma capsulatum and Paracoccidioides brasiliensis were observed. Nested-PCR in blood employing species-specific primers was positive for H. capsulatum and Cryptococcus neoformans. The evaluation of

29. Prevalência da paracoccidioidomicose por intradermorreação em áreas rurais de Alfenas, Minas Gerais, Brasil
Este estudo teve como objetivo estimar a prevalência de sensibilização da pele pelo Paracoccidioides brasiliensis em áreas rurais em Alfenas, MG, Brasil, e avaliar os fatores de risco associados à infecção. Foi realizado um estudo transversal de base populacional utilizando testes intradérmicos com paracoccidioidina em 542 indivíduos selecionados po

30. Efeito da dose resposta de Paracoccidioides brasiliensis no modelo experimental de artrite
A paracoccidioidomicose (PCM) é causada pelo fungo dimórfico Paracoccidioides brasiliensis (Pb) e corresponde à micose sistêmica de maior prevalência na América Latina. O objetivo do presente trabalho foi avaliar a dose resposta de leveduras do fungo para padronização do modelo experimental de artrite séptica. Os experimentos foram realizados com gr

31. In vitro cytotoxic, antifungal, trypanocidal and leishmanicidal activities of acetogenins isolated from Annona cornifolia A. St. -Hil. (Annonaceae)
Annona cornifolia A. St. -Hil. é uma pequena árvore anual perene encontrada no cerrado brasileiro; seu fruto verde é usado popularmente no tratamento de úlceras. As acetogeninas isoladas a partir das sementes de Annona cornifolia anteriormente apresentaram atividade antioxidante. Continuando as nossas investigações sobre as atividades biológicas das a

32. Extra-pulmonary manifestations of paracoccidioidomycosis associated with acquired immunodeficiency syndrome: a case report
We present a patient with Paracoccidioidomycosis/HIV coinfection which has been investigated because of chronic monoarthritis and mucocutaneous lesions. A biopsy of the synovial membrane and skin revealed structures consistent with Paracoccidioides brasiliensis. At diagnosis, the count of CD4 + T cells was 44 cells/mm3. We emphasize the importance of clinica

33. Paracoccidioidomycosis in a western Brazilian Amazon State: Clinical-epidemiologic profile and spatial distribution of the disease
Introduction: Paracoccidioidomycosis (PCM) is a systemic infection caused by the fungus Paracoccidioides brasiliensis. PCM is considered one of the most important systemic mycoses in Latin America. Methods: This is a clinical, epidemiological, retrospective, quantitative study of PCM cases in patients attending the National Health Service in the State of

34. Paracoccidioidomycosis in southern Rio Grande do Sul: a retrospective study of histopathologically diagnosed cases
Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the fungus Paracoccidioides brasiliensis and is endemic to Brazil. The aim of this study was to perform a retrospective analysis of the PCM cases in the countryside south of Rio Grande do Sul, Brazil. The files from four histopathology laboratories located in the city of Pelotas were obtained, and

35. An optimized one-tube, semi-nested PCR assay for Paracoccidioides brasiliensis detection
Introduction Herein, we report a one-tube, semi-nested-polymerase chain reaction (OTsn-PCR) assay for the detection of Paracoccidioides brasiliensis. Methods We developed the OTsn-PCR assay for the detection of P. brasiliensis in clinical specimens and compared it with other PCR methods. Results The OTsn-PCR assay was positive for all clinical samples,

36. The left lung is preferentially targeted during experimental paracoccidioidomycosis in C57BL/6 mice
Paracoccidioidomycosis (PCM) is a chronic systemic mycosis caused by the inhalation of the thermally dimorphic fungus Paracoccidioides brasiliensis as well as the recently described P. lutzii. Because the primary infection occurs in the lungs, we investigated the differential involvement of the right and left lungs in experimental P. brasiliensis infection.
