Effects of a reduced calcium, phosphorus and protein intake and of benzoic acid on calcium and phosphorus metabolism of growing pigs


Gutzwiller, A; Hess, H D; Adam, A; Guggisberg, D; Liesegang, A; Stoll, P (2011). Effects of a reduced calcium, phosphorus and protein intake and of benzoic acid on calcium and phosphorus metabolism of growing pigs. Animal Feed Science and Technology, 168(1-2):113-121.

Abstract

In the last few years, various PCR based methods have been developed that enable detection of Cronobacter spp. to the genus and species level. Moreover, several real-time PCR based systems for detection of Cronobacter spp. are available, however, comparative evaluation studies are not available. The current study represents a comparative evaluation of three commercial diagnostic systems, namely the BAX® System PCR Assay Enterobacter sakazakii (DuPont, Qualicon, Wilmington, USA), the Assurance GDS™ Enterobacter sakazakii (BioControl, Bellvue, USA) and the foodproof® Enterobacter sakazakii Detection Kit (Biotecon Diagnostics, Potsdam, Germany) for the rapid identification of Cronobacter spp. Twenty-one target and non-target strains were included in the study and results were compared for specificity and convenience in performance. A specificity of 100% was observed for two of the three real time PCR systems tested, namely the Assurance GDS™ Enterobacter sakazakii and the foodproof® Enterobacter sakazakii Detection Kit for pure cultures as well as artificially contaminated powdered infant formula (PIF) samples.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
