<P>A one-step real-time PCR using one set of oligonucleotide primers and three probes was developed for differentiation of F4 (K88) variants (F4ab, F4ac, F4ad) of enterotoxigenic Escherichia coli (ETEC) from diarrhoeic pigs. The limits of detection of F4ab, F4ac and F4ad in broth dilution were 10(6), 10(5) and 10(4) colony forming units (CFU)/mL, respectively. In faecal samples spiked with E. coli, the limits of detection of F4ab, F4ac and F4ad were 10(6), 10(6) and 10(4) CFU/g faeces, respectively, without enrichment and 10(3), 10(2) and 10(2) CFU/g faeces following enrichment. In 42 ETEC field isolates from pigs in Korea encoding the F4 gene, all were identified as the F4ac variant. (C) 2012 Elsevier Ltd. All rights reserved.</P>

<P>Recent research in heterogeneous catalysis, especially on size-selected model systems under UHV conditions and also in realistic catalytic environments, has proved that it is necessary to think in terms of the exact number of atoms when it comes to catalyst design. This is of utmost importance if the amount of noble metal, gold in particular, is to be reduced for practical reactions like CO oxidation. Here it is shown that on TiO<SUB>2</SUB> only Au<SUB>6</SUB> and Au<SUB>7</SUB> clusters are active for CO oxidation which holds for the single crystal, thin films, and titania clusters deposited on HOPG. Size-selected cluster deposition and TPD methods have been employed to investigate the CO oxidation activity of Au<SUB><I>n</I></SUB>/TiO<SUB>2</SUB> systems which are compared to recent results reported by Lee <I>et al.</I> to form a consistent picture in which only two species can be regarded as “active”. The efficiency of investigated Au<SUB><I>n</I></SUB>/(TiO<SUB>2</SUB>)<SUB>93</SUB>/HOPG composite materials is attributed to carbon-assisted oxygen spillover from gold to support particles and across grain boundaries.</P> <P>Graphic Abstract</P><P>The probability of creating CO oxidation-active species on TiO<SUB>2</SUB> is very small since only Au<SUB>6</SUB> and Au<SUB>7</SUB> are catalytically active. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c4cp00160e'> </P>
