The authors conducted a matched case-control study in Germany to identify risk factors for sporadic illness associated with Shiga toxin-producing Escherichia coli (STEC) infection, regardless of serogroup. From April 2001 through March 2003, cases were prospectively enrolled through a laboratory-based sentinel surveillance system located in 14 of the 16(More)
47 cattle farms with a total of 6500 cattle in one district of Northrhine-Westfalia took part in a study on the use of antibiotic substances on a voluntary basis. The veterinary application and dispensary documents (section 13 TAHAV) as well as respecting farmers' documents (ANTHV) served as data sources. All consumption data of a one-year-period (1(More)
Every application of antibacterial drugs in veterinary medicine may encourage selection for resistant bacteria. In Germany no valid data are available which would be suitable for a species specific estimation of drug consumption especially regarding food producing animals. Therefore, a representative monitoring of consumption of antibacterial drugs in food(More)
Udder defence mechanisms are not completely explained by current mastitis research. The anatomical construction of the udder implies that infection of one udder quarter does not influence the immune status of neighbouring quarters. To test this hypothesis, we compared the immune reactions of individual udder quarters in response to microbial attacks. In the(More)
A cross-sectional study concerning farm prevalence and risk factors for the count of cefotaxime resistant Escherichia coli (E. coli) (CREC) positive samples per sampling group on German fattening pig farms was performed in 2011 and 2012. Altogether 48 farms in four agricultural regions in the whole of Germany were investigated. Faecal samples, boot swabs(More)
The objective of the study was to determine the prevalence of Campylobacter spp. on surfaces of slaughtered pig livers. Multilocus sequence typing (MLST) was performed to determine the sequence types (STs) of selected Campylobacter coli isolates. Additionally, C. coli and Campylobacter jejuni isolates were tested for antimicrobial susceptibility by the(More)
The implementation of the European regulations regarding zoonoses demands objective and scientific statements regarding the status of the Salmonella prevalence in the national pig herds of all EU member states. Since 2002, the "QS Qualität und Sicherheit GmbH" has carried out serological Salmonella monitoring in German finishing pig herds. All data(More)
In order to simplify the design of representative studies in animal populations the structural differences of animal husbandry (cattle, pigs and laying hens) in Germany were characterised. Several regions were defined and thus districts identified which are typical for the respective region and can be regarded as representatives for the whole region. Data(More)
To be able to analyze the relationship between the level of resistance and the use of antimicrobials, it is necessary to collect detailed data on antimicrobial usage. For this reason, data on antimicrobial use on 495 pig farms from entire Germany were collected and analyzed. In Germany, each application and dispensing of medicines to food-producing animals(More)
BACKGROUND Within a feasibility study the use of antibiotics in pigs and cattle was determined in 24 veterinary practices in Lower Saxony and on 66 farms in North Rhine-Westphalia in Germany. Focus was laid on the comparison of the Used Daily Doses (UDD) (dose per animal and day prescribed by the veterinarians) with the Defined Animal Daily Doses (ADD)(More)
