| plasmodium vivax sporozoite antibodies in individuals exposed during a single malaria outbreak in a non-endemic area. | we studied seroreactivity against plasmodium vivax antigens in 62 individuals living in a small community near mantena, minas gerais, brazil, an area outside the endemic malaria zone brazil. eight months earlier, there had been transmission of p. vivax for a period of 50 days, which was then totally controlled by chemotherapy and insecticides. an anti-sporozoite response, measured by elisa using a recombinant protein expressed in yeast, was detected in 45% (14 of 31) of individuals eight months ... | 1991 | 1996737 |
| persistence of humoral response against sporozoite and blood-stage malaria antigens 7 years after a brief exposure to plasmodium vivax. | the persistence of malarial antibodies was evaluated in subjects living in a rural community (in minas gerais state, brazil) briefly exposed to a plasmodium vivax malaria outbreak outside of the area in which malaria was endemic. transmission was interrupted by treatment of all patients and their relatives and/or neighbors, although the latter had neither symptoms nor blood parasites. antibodies to p. vivax antigens (recombinant proteins from sporozoites [rpvcs] and from blood stages [rpv200]) w ... | 1998 | 9535000 |
| 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 ... | 1998 | 9776810 |
| 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%). ... | 2000 | 10892986 |
| yeast communities and genetic polymorphism of saccharomyces cerevisiae strains associated with artisanal fermentation in brazil. | yeast communities and genetic polymorphism of prevalent saccharomyces cerevisiae strains isolated from the spontaneous fermentation of the sugarcane juice during the production of aguardente in three distilleries in the state of minas gerais, brazil, were studied. s. cerevisiae was the prevalent species during the process of aguardente production, but schizosaccharomyces pombe was predominant in old fermentations in one distillery. transient yeast species were found in a variable number, probabl ... | 2000 | 10945775 |
| microbial diversity during maturation and natural processing of coffee cherries of coffea arabica in brazil. | the magnitude and diversity of the microbial population associated with dry (natural) processing of coffee (coffea arabica) has been assessed during a 2-year period on 15 different farms in the sul de minas region of brazil. peptone water-washed samples were taken of maturing cherries on trees (cherries, raisins and dried cherries) and from ground fermentations. the microbial load varied from 3 x 10(4) to 2.2 x 10(9) cfu/cherry with a median value of 1.6 x 10(7) cfu/cherry. the microbial load in ... | 2000 | 11016614 |
| microbiology and physiology of cachaça (aguardente) fermentations. | cachaça (aguardente) is a rum-style spirit made from sugar cane juice by artisanal methods in brazil. a study was made of the production, biochemistry and microbiology of the process in fifteen distilleries in sul de minas. identification of 443 yeasts showed saccharomyces cerevisiae to be the predominant yeast but rhodotorula glutinis and candida maltosa were predominant in three cases. bacterial infection is a potential problem, particularly in older wooden vats, when the ratio of yeasts:bacte ... | 2001 | 11392489 |
| identification and antimicrobial susceptibility of micro-organisms recovered from cutaneous lesions of human american tegumentary leishmaniasis in minas gerais, brazil. | an evaluation of the microbiota present in cutaneous ulcers from 31 patients with a clinical and parasitological diagnosis of american tegumentary leishmaniasis (atl) was carried out by the standard filter paper disc technique, including antimicrobial susceptibility of the bacterial isolates. microbial examination indicated that 21 patients (67.7%) were contaminated with one to four bacteria and some of them also with yeast. a total of 142 micro-organisms were isolated. staphylococcus aureus was ... | 2005 | 16192439 |
| predisposing conditions for candida spp. carriage in the oral cavity of denture wearers and individuals with natural teeth. | candida species are a normal commensal present in a large percentage of healthy individuals. denture wearers are predisposed to the development of candidosis and to the presence of candida spp. the presence of the yeast, even in healthy subjects, should be considered more carefully. we investigated the prevalence of candida spp. in 112 denture wearers and 103 individuals with natural teeth, patients from the clinic of total prosthesis of the dental school of the federal university of minas gerai ... | 2006 | 16699571 |
| [fungic microbiota of normal conjunctiva, sugar-cane and anemophilous fungi of the region of monte belo - minas gerais]. | to evaluate the incidence of fungi in the ocular conjunctiva of sugar-cane cutting workers as well in a sugar-cane plantation environment. | 2007 | 17768551 |
| biochemical and molecular characterization of saccharomyces cerevisiae strains obtained from sugar-cane juice fermentations and their impact in cachaça production. | saccharomyces cerevisiae strains from different regions of minas gerais, brazil, were isolated and characterized aiming at the selection of starter yeasts to be used in the production of cachaça, the brazilian sugar cane spirit. the methodology established took into account the screening for biochemical traits desirable in a yeast cachaça producer, such as no h2s production, high tolerance to ethanol and high temperatures, high fermentative capacity, and the abilities to flocculate and to produc ... | 2008 | 18065624 |
| incidence and anatomic localization of oral candidiasis in patients with aids hospitalized in a public hospital in belo horizonte, mg, brazil. | the objective of this study was to evaluate the incidence, anatomic localization and yeast species isolated from each clinical type of oral candidiasis. the clinical samples were obtained from 67 patients with aids with cd4 cell counts below 200 cells/mm(3) and hospitalized in a public hospital (eduardo de menezes hospital) in the city of belo horizonte, mg, brazil. yeasts were isolated using chromagar candida. the results show that 50.7% of these patients had oral candidiasis. the pseudomembran ... | 2008 | 19089255 |
