Clinical signs such as gastrointestinal problems may be better predictors of mortality in neonatal calves with diarrhea than blood pH levels and other laboratory findings, suggests a new study co-written by University of Illinois veterinary medicine dean Peter Constable; Florian M. Trefz and Annette Lorch, both of the Center of Veterinary Clinical Medicine at Ludwig Maximilian University of Munich; and Ingrid Lorenz, of the Bavarian Animal Health Service.
Cystoisospora suis causes diarrhea especially in newborn piglets and spreads quickly across farms. European farmers preventively use toltrazuril to control parasite development. In contrast to congeneric chicken parasites, no resistance to toltrazuril was described in pig parasites until recently. Researchers of Vetmeduni Vienna now confirmed ineffectivness of toltrazuril against a Dutch isolate. Although the resistance develops slowly, monitoring should be intensified due to the lack of alternative treatment options and hygiene measures should be increased.
Based on currently available knowledge, the German Federal Institute for Risk Assessment (BfR) assumes that illegal applications of products containing fipronil have apparently been carried out over an extended period of time. For this reason, the longer term consumption of foods contaminated with fipronil has to be given due consideration when assessing the risks.
The German Federal Institute for Risk Assessment has prepared a health risk assessment based on limited available data on fipronil levels in foods (containing eggs) in Germany.
In collaboration with teams from the Czech Republic and Japan, researchers from the Institut Pasteur, (AP-HP), and (AP-HM) have identified the likely origin of the cross-reactivity between cypress pollen, peaches and citrus fruits. Their work has shown that these sources contain allergens belonging to a new family of proteins involved in pollen food associated syndrome. This discovery, published in JACI on Aug. 3, paves the way for the development of novel allergy diagnostic tests.
Society's ability to solve environmental problems is tied to how different actors collaborate and the shape and form of the networks they create, says a new study from researchers at Stockholm Resilience Centre which is published in the journal Science.
Climate change and habitat conversion to agriculture are working together to homogenize nature, indicates a study in the journal Global Change Biology led by the University of California, Davis. In other words, the more things change, the more they are the same.
Researchers say their new knowledge on the inner workings of a bacterium has important implications for Australia's billion dollar cheese industry. University of Queensland School of Agriculture and Food Sciences researcher Associate Professor Mark Turner said a discovery by a UQ, Columbia University and University of Washington research group had explained the regulation of an enzyme in the bacterium Lactococcus, which is used as a starter culture in cheese production.
In a recent report published in Nature Microbiology, University of Hawai'i at Mānoa (UHM) oceanography professor Ed DeLong and his team report the largest single-site microbiome gene catalog constructed to date. With this new information, the team discovered nutrient limitation is a central driver in the evolution of ocean microbe genomes.
With more than two dozen companies in Pennsylvania manufacturing potato chips, it is no wonder that researchers in Penn State's College of Agricultural Sciences have developed a novel approach to more efficiently convert potato waste into ethanol. This process may lead to reduced production costs for biofuel in the future and add extra value for chip makers.
