prevalence of paracoccidioidomycosis infection by intradermal reaction in rural areas in alfenas, minas gerais, brazil.this study aimed to estimate the prevalence of paracoccidioidal infection by intradermal reaction (delayed-type hypersensitivity, dth) to paracoccidioides brasiliensis in rural areas in alfenas, southern minas gerais (mg) state, brazil, and to assess risk factors (gender, occupation, age, alcohol intake and smoking) associated with infection. we conducted a population-based cross-sectional study using intradermal tests with gp 43 paracoccidioidin in 542 participants, who were previously contacte ...201725076426
seroepidemiological survey of paracoccidioidomycosis infection among urban and rural dogs from uberaba, minas gerais, brazil.there is some evidence that dogs can be naturally infected by paracoccidioides brasiliensis in endemic areas of paracoccidioidomycosis. in order to evaluate canine infection with this fungus, a survey with 149 urban and 126 rural dogs was carried out using elisa and intradermal tests with the gp43 antigen of p. brasiliensis in uberaba, minas gerais state of brazil. forty-one out of 149 urban dogs were euthanatized and had their lungs, liver and spleen removed. one slice from each viscera was pro ...201019768574
[seroepidemiological survey for infections by fungi causing systemic mycoses in the xacriabá indian reserve, minas gerais state, brazil].xacriabá indian reserve is situated in the north of minas gerais state, brazil, near the municipality of manga and são francisco river. the indian population is miscegenated with caucasian and negroid people and have farming activities. blood samples were collected from 180 inhabitants of the reserve (85 men and 95 women), 15 to 84 years old. serum antibodies against antigens of paracoccidioides brasiliensis, histoplasma capsulatum, cryptococcus neoformans, and candida albicans were tested for b ...200212170330
the marsupial didelphis albiventris is an improbable host of paracoccidioides brasiliensis in an endemic area of paracoccidioidomycosis in minas gerais, brazil.to determine whether didelphis albiventris is naturally infected with paracoccidioides brasiliensis, 20 specimens of this mammal were studied by both direct cultivation of their viscera (spleen, liver and lungs) and by inoculation of swiss mice by the intraperitoneal route with a suspension of fragments of these viscera. no fungal growth or structures similar to this fungus were detected. probably d. albiventris is not frequently infected with p. brasiliensis.200111562699
isolation of paracoccidioides brasiliensis from armadillos (dasypus novemcinctus) in an area where the fungus was recently isolated from soil.natural infection of armadillos (dasypus novemcinctus) with paracoccidioides brasiliensis in northern brazil was reported in 1986, raising great interest in the understanding of the role of this mammal in the epidemiological cycle of the fungus. recently, p. brasiliensis was isolated from the soil of ibiá, state of minas gerais, southeastern brazil. armadillos captured in this area were evaluated for the presence of p. brasiliensis in the viscera and infection was detected in 4/16 animals (25%). ...200010892986
role of the armadillo dasypus novemcinctus in the epidemiology of paracoccidioidomycosis.a study conducted in a rural area of ibiá, state of minas gerais, brazil, where paracoccidioides brasiliensis was recently isolated from soil, sought to determine if the armadillo dasypus novemcinctus developed paracoccidioidomycosis. out of 21 armadillos captured in the area, one had a lung granuloma containing fungal cells attributable to those of p. brasiliensis. the present report presents the first histopathological evidence for the presence of this pathogen in the lungs of an armadillo. th ...199810531678
isolation of a paracoccidioides brasiliensis strain from the soil of a coffee plantation in ibiá, state of minas gerais, brazil.paracoccidioides brasiliensis has rarely been isolated from its habitat in rural areas. in order to investigate the hypothesis that human infection with this fungus is linked to coffee plantations (coffea arabica), material was collected monthly over a period of 1 year from farms in the town of ibiá, state of minas gerais, brazil. a total of 760 samples of soil, coffee leaves and fruits was cultured and inoculated into mice. a fungus isolated from the liver of a mouse inoculated with soil showed ...19989776810
epidemiologic skin test survey of sensitivity to paracoccidioidin, histoplasmin and sporotrichin among gold mine workers of morro velho mining, brazil.skin tests with paracoccidioidin, histoplasmin and sporotrichin were applied to 417 workers of morro velho mining in the state of minas gerais, brazil, with the main purpose of detecting the prevalence of paracoccidioidomycosis-infection, histoplasmosis capsulate-infection and sporotrichosis-infection. the rates of positivity to the skin tests were 13.43% for paracoccidioidin, 17.50% for histoplasmin and 13.67% for sporotrichin. several epidemiological factors were investigated for a better inte ...19969063004
