Effect of hemolysis on canine, bovine and earn e serum chemistry

Hemolysis is the main cause of biochemical analysis rejection's in veterinary laboratories, however the relative error caused by hemoglobin on serum biochemical profile has not been properly established on several species. In order to establish criteria for aproval and rejection of hemolyzed samples for serum biochemical tests, the hypothesis that hemolysis causes biochemical changes in canine, cattle and horses and that laboratorial error depends on species and hemolysis degree was tested. Thus, non-hemolyzed serum was contaminated with crescent hemoglobin levels and using commercial routine reagents, the serum concentrations of uric acid, albumin, cholesterol, triglycerides and urea, besides the activity of ALT, AST, CK and GUT were quantified in triplicate samples. The relative error was calculated by the comparison between hemolyzed and non-hemolyzed samples. Hemolys is did not cause significant error on the albumin determination in all three species, AST in canine and cattle, ALT in horses, UK and cholesterol in canine. There was a linear increase on uric acid levels in horses and cattle, triglycerides in all three species. A linear increase in serum urea in all species serum, UK and cholesterol in cattle and cholesterol in horses was observed. Serum AST activity on equine serum and ALT in cattle decreased linearly due to hemolysis. It was concluded that hemolysis promotes changes in canine, equine and bovine serum chemistry profile, however the laboratorial error not necessarily compromises the diagnosis in all cases, because the changes depends on species and degree of in vitro hemolysis.

Assessment of fungi in soils of sugarcane crops and their potential for production of biomass-degrading enzymes

Soil management practices are konwn to affect the biomass and enzyme activities of microbial soil communities. To assess whether burning of sugarcane prior to harvesting affects the community of soilborne fungi, we collected soil simples in two sites: burned sugarcane culture prior harvesting (BS) and non-burned sugarcane culture (NBS). A total of 75 filamentous fungal isolates were recovered from soils in both sites. Trichoderma was the most prevalent genus in both sites, followed by Fusarium, Cunninghamella and Aspergillus. The Sorensen's index (0.60) suggested a slight difference in fungi associated with both areas, with high number of fungal isolates found on BB soil. The abundance of Trichoderma isolates in NBS soil was higher than BS soil; however, the abundance of Fusarium, Aspergillus and Cunninghamella was higher in the latter type of soil. In addition, fungi isolated from BS soil showed the highest production of xylanase and laccase in comparision with fungi isolated form NBS soil. Our results indicate that the different types of sugarcane harvesting apparently did not interfere with the diversity of fungal communnities as revealed by culture-dependent methods. In addition, our data indicates the potencial of fungi from soils of sugarcane crops to produce relevant enzymes related to biomass conversion.
