We investigated whether spray-dried plasma (SDP) improved growth and health of piglets challenged with enterotoxigenic Escherichia coli K88 (ETEC). Forty-eight pigs weaned at 21 d (BW = 4.88 +/- 0.43 kg) received one of four diets containing 6% SDP or fish proteins (as-fed basis) either nonmedicated (SDP-NM and FP-NM diets) or medicated with 0 or 250 mg/kg(More)
the different regions of Germany. In contrast, within these particular geographic areas, only slight sequence differences were found in longitudinal analysis over several years. This conclusion is supported by the novel human Waldkirchen sequence (H72), which is almost identical to the BF strains from 2004 (6,10) and the similarity of newly derived human(More)
A survey for methicillin-resistant Staphylococcus aureus (MRSA) in finishing pig holdings was carried out in Italy in 2008. MRSA isolates were characterised by spa-, MLST-, SCCmec- and antimicrobial susceptibility typing. A prevalence of 38% (45/118, 95% CI 29.4-46.9%) positive holdings was observed. Eleven different spa-types were found among 102 MRSA(More)
There was an epidemic of diarrhoea affecting pigs of all ages in Italy between May 2005 and June 2006. In 63 herds the cause was confirmed as porcine epidemic diarrhoea virus by electron microscopy, immunoelectron microscopy, pcr and serology. Watery diarrhoea without mucus and blood was usually associated with a reduction of feed consumption. In(More)
Cranioventral pulmonary consolidation (enzootic pneumonia-like lesions) and chronic pleuritis (CP) are common findings in slaughtered pigs. Pleural lesions involving dorsocaudal lobes are suggestive of pleuropneumonia due to Actinobacillus pleuropneumoniae. In this report the results of an abattoir survey of pleuritis and pulmonary lesions in pigs is(More)
Nine Chlamydia suis isolates, obtained from pigs with conjunctivitis, were molecularly characterized by ompA sequencing and their in vitro susceptibility to six cathelicidin peptides (SMAP-29, BAC-7, BMAP-27, BMAP-27, BMAP-28, PG-1, LL-37) determined in cell culture. SMAP-29 was the most active peptide, reducing the intracellular inclusion number by > or(More)
In 2012-2013 Emilia-Romagna Region introduced a monitoring plan for Shiga toxin-producing Escherichia coli (STEC) in foodstuff. Six hundred eighty-nine meat samples and 273 fruit and vegetable products were analyzed according to ISOTS13136. Pre-enriched samples were tested by multiplex real time PCR targeting the virulence genes eae, stx1 and stx2. Stx2(More)
From January 2007 to December 2011, a total of 106 Haemophilus parasuis strains isolated from pigs were serotyped by agar gel diffusion test (DG). Serovar 4 was the most prevalent (24.5%), followed by serovar 13 (19.8%) and serovar 5 (11.3%). Twenty-nine strains were non-typeable (27.3%). The strains were divided into two groups, depending on whether they(More)
