Honey, royal jelly, propolis, materials produced and/or gathered by Apis mellifera honeybees have been used as food and medication for centuries(6,7,8). Although extensively used, honeybee products have become a matter of interest and controversy for years. Honey, well known as healthy and natural food, has shown therapeutic properties in the treatment of digestive, respiratory, cardiac and rheumatic disorders, among others(4). Several studies have reported honey's immunological, antibacterial, antiinflammatory, antipyretic properties besides its importance in terms of energy intake(3,5). Furthermore, honey has proved to possesses wound healing and analgesic actions(1,2). Honey and propolis are also known to be effective in the treatment of respiratory...

Provedor de dados: 80
Autores: Kamikawa,CM; Kohara,VS; Passos,AN; Vicentini,AP.
The geographic distribution of paracoccidioidomycosis (PCM) in the Brazilian state of São Paulo was evaluated in a retrospective study using secondary data from serological analyses, carried out by double immunodiffusion assay of patients with PCM suspicion, from January 1999 to May 2010. Sixty percent of 10,176 patients, from 239 cities, were serologically reactive to P. brasiliensis. The cities that showed the most serological reactivity among patients were São João da Boa Vista (85%), Piracicaba (75%), Sorocaba (73%), Campinas (72%) and São Paulo (62%). São Paulo state has an area of 248,209.4 km²; the climate is tropical and sub-tropical with annual temperatures between 18 and 24ºC, high rainfall (900 to 1800 mm/year), rainy summers and mild winters....

Standardization and validation of Dot-ELISA assay for Paracoccidioides brasiliensis antibody detection
Provedor de dados: 80
Autores: Kamikawa,Camila Mika; Mendes,Rinaldo Poncio; Vicentini,Adriana Pardini.
Abstract  Background  Paracoccidioidomycosis (PCM) is a neglected systemic mycosis caused by a dimorphic fungus of the Paracoccidioides genus. The standard diagnosis is based on isolation of the fungi in culture, and by microscopic visualization of characteristic multiple budding yeast cells in biological samples. However, in some situations, access to the site of injury prevents the collection of biological material. A variety of immuno-serological techniques has proven useful for allowing inferring diagnosis with a certain degree of certainty, thus optimizing time. The aim of this study was to standardize and validate the Dot-ELISA (DE) assay, comparing it with the serological standard, double immunodiffusion (DI).  Methods  In order to standardize the...

Provedor de dados: 80
Autores: Silva,D. F.; Assis,C. M.; Zamboni,I. M.; Barreto,L. C.; Kohara,V. S.; Vicentini-Moreira,A. P.
The purpose of this work was to evaluate two serological assays: double immunodiffusion (DI) and immunoblotting (IB) in immunodiagnosis of paracoccidioidomycosis (PCM). We evaluated by IB assay 23 sera samples from patients with clinical confirmation of PCM, all of them with negative DI results against culture filtrate from Paracoccidioides brasiliensis isolate 113. For IB, as well as for comparative DI assay, we employed soluble components of the cell wall outer surface (SCCWOS) from P. brasiliensis isolate 113 cultivated at 36°C in Fava-Neto's agar medium for 5 and 10 days. Among the 20 sera samples analyzed by DI, 13 (65%) were negative and 7 (35%) were positive against SCCWOS obtained on the 5th and 10th days. By IB assay, 95.4% and 100% of sera...

The objective of this work was to evaluate biochemical parameters in Paracoccidioides brasiliensis infected mice and the effect of Canova medicine on these parameters. Mice infected with the isolate Paracoccidioides brasiliensis Pb18 and treated with Canova for 17 weeks were used. The biochemical parameters analysed were the levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and amylase, and the concentration of total proteins, albumin and globulins. The results suggested that the animals that were treated with Canova had less functional alterations in their internal organs.

Nuclear medicine in tropical diseases
Provedor de dados: 52
Autores: Braga,Francisco José Hossri Nogueira.
Tropical diseases affect more people in the world than any other kind of disease, but scintigraphic data on that matter are not so frequent in the literature. Since the geographic regions where such diseases occur are normally very poor, scintillation cameras may not be available. We present a resumed summary of part of what has been done on this subject to-date. Leprosy affects circa 12 million people worldwide and has already been studied by means of the following scintigraphic exams: Gallium-67, 99mTc-MDP or HMDP, 99mTc-colloid or Dextran, 99mTc-DTPA and 99mTc-WBC. Paracoccidiodomycosis is a deep mycosis and such cases may be evaluated by means of Gallium-67, bone scintigraphy, lymphoscintigraphy, hepato-billiary, bone marrow and liver / spleen...

Validation and clinical application of a nested PCR for paracoccidioidomycosis diagnosis in clinical samples from Colombian patients
Provedor de dados: 55
Autores: Gaviria,Marcela; Rivera,Vanessa; Muñoz-Cadavid,Cesar; Cano,Luz Elena; Naranjo,Tonny Williams.
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 to respiratory specimens, body fluids and/or biopsies; however these methods require laboratory personnel with experience and several days to produce a result. In the present study, we have validated and evaluated a nested PCR assay targeting the gene encoding the Paracoccidioides gp43membrane protein in 191 clinical samples: 115 samples from patients with proven infections other than...

The low efficiency of dendritic cells and macrophages from mice susceptible to Paracoccidioides brasiliensis in inducing a Th1 response
Provedor de dados: 56
Autores: Almeida,S.R.; Lopes,J.D.
In the present study we evaluated T cell proliferation and Th lymphokine patterns in response to gp43 from Paracoccidioides brasiliensis presented by isolated dendritic cells from susceptible and resistant mice. T cell proliferation assays showed that dendritic cells from susceptible mice were less efficient than those from resistant mice. The pattern of T cell lymphokines stimulated by dendritic cells was always Th1, although the levels of IL-2 and IFN-gamma were lower in T cell cultures from susceptible mice. To determie whether different antigen-presenting cells such as macrophages and dendritic cells stimulated different concentrations of Th1 lymphokines, the production of IFN-gamma and IL-2 was measured. It was observed that dendritic cells were more...

Provedor de dados: 56
Autores: Tristão,F.S.M.; Rocha,F.A.; Dias,F.C.; Rossi,M.A.; Silva,J.S.
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. Lungs were collected from C57BL/6 mice at 70 days after intravenous infection with 1×106 yeast cells of a virulent strain of P. brasiliensis (Pb18). The left lung, which in mice is smaller and has fewer lobes than the right lung, yielded increased fungal recovery associated with a predominant interleukin-4 response and diminished synthesis of interferon-γ and nitric oxide compared with the right lung....

Recombinant 60-kDa heat shock protein from Paracoccidioides brasiliensis: is it a good antigen for serological diagnosis of paracoccidioidomycosis?
Provedor de dados: 56
Autores: Peron,G.; Fernandes,F.F.; Landgraf,T.N.; Martinez,R.; Panunto-Castelo,A.
Paracoccidioides brasiliensis and P. lutzii are fungi that cause paracoccidioidomycosis (PCM), the most prevalent systemic mycosis in South America. For serological diagnosis, although 43-kDa glycoprotein (gp43) is regarded as highly specific for PCM, the occurrence of false negative reactions in sera from patients infected with P. lutzii suggests that preparation with only one antigen is not recommended. Heat shock proteins are feasible alternatives as a second antigen because they are often highly immunogenic. In this study, we evaluated the usefulness of recombinant 60-kDa heat shock protein from P. brasiliensis (rPbHsp60) for the serological diagnosis of PCM. Using western blotting assay, we observed that 77.3% of the sera from PCM patients were...

Autores: Bianchini,A.A.C.; Petroni,T.F.; Fedatto,P.F.; Bianchini,R.R.; Venancio,E.J.; Itano,E.N.; Ono,M.A.
The dimorphic fungus Paracoccidioides brasiliensis is the etiological agent of paracoccidioidomycosis, a human granulomatous disease. Recently the first case of natural disease in dogs was reported. The complement system is an important effector component of humoral immunity against infectious agents. Therefore, the aim of this study was to evaluate the activation of the dog alternative complement pathway by P. brasiliensis. Initially, the ability of erythrocytes of guinea pig, rabbit, sheep, chicken and swine to activate the dog alternative pathway was evaluated. The guinea pig erythrocytes showed the greatest capacity to activate dog alternative pathway. The alternative (AH50) hemolytic activity was evaluated in 27 serum samples from healthy dogs and the...

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 from the mesoregion of Southwest Riograndense, using these animals as sentinels. Serological techniques, such as double immunodiffusion in agar gel (AGID) and indirect ELISA, were performed to detect the anti-gp43 P. brasiliensis antibody in horses from five different farms in the region of Bagé, RS, Brazil. Serology was performed in 200 Pure Blood English horses up to two years of age that were born and...

Provedor de dados: 58
Autores: Macêdo,Danielle Patrícia Cerqueira; Neves,Rejane Pereira; Magalhães,Oliane Maria Correia; Lacerda Filho,Armando Marsden.
This paper reports an unusual case of paracoccidioidomycosis with ulcerations in the head and nose in a Brazilian man. For diagnosis, direct microscopic examination of ulcer secretion and skin samples treated with potassium hydroxide was performed. The isolation of Paracoccidioides brasiliensis occurred at 28ºC and 37ºC on Sabouraud agar with chloranphenicol. Diagnosis was established by the presence of isolated and multiple budding yeast-like cells and typical fungus growth of P. brasiliensis.

Autores: Unterkircher,Carmelinda S.; Leão,Mariella V.P.; Blotta,Maria Heloisa S.L.; Camargo,Zoilo Pires de.
Recent attention has been focused on the natural antibodies as a component of natural immunity and as integral part of the idiotypic network. However, their functional role in different infections has rarely been studied. This work was undertaken to investigate the presence of natural antibodies in paracoccidioidomycosis (PCM). In addition, we analyzed anti-P. brasiliensis antibodies and their distribution in IgG subclasses in order to acquire better knowledge about the humoral immune response in this mycosis. Our findings show that the natural antibody response is not very much increased in PCM when compared with other parasite infections and this response is restricted to a few specificities, suggesting that P. brasiliensis moderately triggers CD5+ B...
