| the natural occurrence of fumonisins in brazilian corn kernels. | since animal intoxication related to corn-based feed is frequently observed in the state of paraná, brazil, natural contamination by fumonisins in 48 corn samples (39 from the state of paraná, and 9 from the brazilian tropical states, mato grosso do sul and goias) harvested in 1990-1991 was investigated, along with fungal flora. the total mould count ranged from 6.3 x 10(2) to 5.5 x 10(7) cfu/g, and fusarium moniliforme and aspergillus species belonging to section flavi were detected in 41 and 3 ... | 1996 | 9064243 |
| mycoflora and fumonisin contamination in brazilian corn from sowing to harvest. | the present study aimed to analyze the mycoflora and potential mycotoxin contamination of soil and corn samples collected at different plant maturity stages in capão bonito and ribeirão preto, two regions of the state of são paulo, brazil. in addition, the data obtained were correlated with the occurrence of wind-dispersed fungi and the predominant climatic conditions of the two regions studied. corn mycoflora profiles showed that fusarium verticillioides prevailed in 35% of the samples from cap ... | 2002 | 12059175 |
| ochratoxin a in serum of swine from different brazilian states. | the aims of the current study were to monitor the presence of ochratoxin a (ota) in the serum of slaughtered swine and to investigate its distribution in 4 major geographical regions of brazil. a total of 400 samples of serum were collected from 4 major states of brazil (100 samples each). ochratoxin a concentrations were determined by high-performance liquid chromatography. in santa catarina state, 60% of the samples had ota concentrations ranging from 4.01 to 75.4 mg/l. in mato grosso state, 7 ... | 2010 | 20807935 |
| fungal microbiota in air-conditioning installed in both adult and neonatal intensive treatment units and their impact in two university hospitals of the central western region, mato grosso, brazil. | to evaluate fungal microbiota in air-conditioning units installed in intensive care units in two university hospitals in cuiaba city, mato grosso, central western region of brazil, 525 solid environmental samples were collected, 285 from hospital a and 240 from hospital b. collections were performed using sterile swabs on air-conditioning unit components: cooling coils, ventilators, and filters. mycelial fungi identification was achieved by observation of the macroscopic and micromorphological c ... | 2011 | 21424438 |
