In this study the effect of different cropping systems and crop successions was evaluated on natural Fusarium sp. contamination and fumonisin levels in corn. The cropping systems consisted of a conventional and no-tillage area cultivated with corn in the summer following either oats or fallow in the winter (2006 and 2007 growing seasons). In addition, the(More)
Idiopathic tracheal stenosis is uncommon. Herein, we report four cases, all presenting a similar clinical profile: diagnosed through bronchoscopy and having a history of being treated unsuccessfully for bronchospasm. Three of the patients were treated with dilatation and an oral corticosteroid. One of those three underwent tracheoplasty. In the remaining(More)
The objective of the present study was to assess the degree of exposure of broiler chicken to mycotoxins through naturally contaminated feed and the hygienic quality of feeds. For this purpose the total fungal count and occurrence of fumonisins and aflatoxins were evaluated in four feed types intended for broilers (n = 158), collected from a poultry(More)
Porcine enteropathogenic Escherichia coli (PEPEC) produce an outer membrane protein (intimin) called Paa (porcine attaching and effacing-associated), which is involved in the pathogenesis of E. coli in piglets with diarrhea. The paa gene of a PEPEC strain isolated in Paraná, Brazil, was amplified by polymerase chain reaction, sequenced, and cloned into the(More)
Background: The anatomy of small saphenous vein (SSV) is very variable because of its complex embryological origin. SSV incompetence often causes reflux that goes to the perforating veins, sometimes not respecting the anatomical course. Objective: To analyze differences in reflux direction and reentry in the SSV. Methods: In this prospective, observational(More)
