The frequency of PRRSV corresponding to live vaccines and wild-type was determined in 902 pigs from North-Western Germany submitted for post-mortem examination. Overall, 18.5% of the samples were positive for the EU wild-type virus. EU genotype vaccine virus was detected in 1.3% and the NA genotype vaccine virus in 8.9% of all samples. The detection of the(More)
In 2007, 678 pigs of all age groups out of 347 different farms from Lower Saxony and Northrhine-Westphalia and 86 persons occupationally exposed to pigs were investigated for their nasal colonisation with methicillin-resistant Staphylococcus areus (MRSA) by the Field Station for Epidemiology of the University of Veterinary Medicine Hannover and the Robert(More)
Eight Staphylococcus aureus isolates collected from 117 wild boars were characterized and compared to livestock isolates. They belonged to sequence types ST133, ST425, and the new type ST1643. The spa types were t1181, t6782, and the new types t6384, t6385, and t6386. Antimicrobial susceptibility testing and microarray-based genotyping confirmed the absence(More)
An increasing number of reported detections of methicillin-resistant Staphylococcus aureus (MRSA) in food animals since 2007 has led to the assumption that there is an emerging zoonotic problem with livestock associated (la)MRSA potentially aggravating the MRSA problem in humans. It was the objective of the study to investigate, whether MRSA was present in(More)
The study presents first experiences on the controlled use of respiratory masks against Methicillin-resistant Staphylococcus aureus (MRSA) in a multi-person veterinary pig practice. Seven veterinarians entered the trial (five wearing masks, two wearing no masks) after the veterinarians had performed a decolonisation protocol. The pig herds were visited(More)
This study presents data on the intra-herd prevalence and colonisation dynamics of Methicillin-resistant (MRSA) and Methicillin-sensible (MSSA) Staphylococcus aureus in two independent pig herds located in the Northwest of Germany. Swabs taken from the nasal cavity of sows and piglets, from the udder of the sows and from the direct environment of the pigs(More)
Zoonotic infections with hepatitis E virus (HEV) genotype 3 are presumably transmitted via contaminated pig meat products, which raises the necessity for enhanced serological surveillance of pig herds. The aim of the study was to set up a novel protein expression system to overcome the well-known problems in (HEV-) protein expression using the standard(More)
The most important pork-borne zoonotic diseases in humans such as Salmonelloses and Yersinioses cause only latent infections in pigs. Thus, the infection of pigs does not result in apparent or palpable alterations in the pig carcasses. This is the major reason, why the traditional meat inspection with adspection, palpation and incision is not able to(More)
BACKGROUND European and national administrative legislation require objective evaluation systems for organ lesions at pig slaughter. These results can be used as basis for herd health improvement programs by farmers and their consulting veterinarians. Various studies have shown that the current evaluation and recording of lesions by authorized meat(More)
Bordetella bronchiseptica causes infections of the respiratory tract in swine and other mammals and is a precursor for secondary infections with Pasteurella multocida. Treatment of B. bronchiseptica infections is conducted primarily with antimicrobial agents. Therefore it is essential to get an overview of the susceptibility status of these bacteria. The(More)
