BACKGROUND In May 2003 the Soest County Health Department was informed of an unusually large number of patients hospitalized with atypical pneumonia. METHODS In exploratory interviews patients mentioned having visited a farmers' market where a sheep had lambed. Serologic testing confirmed the diagnosis of Q fever. We asked local health departments in(More)

Zika virus is an emerging mosquito-borne flavivirus currently causing large epidemics in the Pacific Ocean region and Brazil. Clinically, Zika fever resembles dengue fever, but is less severe. Whereas the clinical syndrome and laboratory diagnostic procedures have been described, little attention was paid to the immunology of the disease and its possible(More)
We studied microvascular injury after myocardial cryothermia in rats using intravital fluorescence microscopic techniques. Cryolesions were induced to the right ventricle by freezing with -160 degrees C (probe diameter: 5 mm) for a total of 5 min. Fluorescence microscopy was performed at 15, 30, 60, 90, and 120 min as well as at 3 and 7 days after(More)
Ixodid ticks are important vectors of human pathogens in Central Europe. Despite this fact, prevalence studies are scarce, especially with regard to much-frequented peri-urban recreation sites. In this pilot study, 4.014 larvae, nymphs and adult ticks sampled monthly during the active seasons in 2011 and 2012 from 14 distinct collection sites in two German(More)
The diagnosis of viral myocarditis remains difficult and generally depends on clinical and histologic criteria. Viral cultures and serology are often unrewarding with low yields. The purpose of this study was to analyze the usefulness of PCR in the rapid diagnosis of myocarditis in children. PCR was used to analyze 120 myocardial tissue samples from 60(More)
Microvascularization of infarcted myocardial tissue may be a prerequisite for successful therapeutic interventions, including cardiomyoblast or satellite cell transplantation. Because little is known on microvascular restitution within infarcted tissue, we studied angiogenesis and microvascularization after cryothermia-induced myocardial infarction using(More)
The EHEC O104:H4 outbreak 2011 in Germany provided numerous insights into the recognition and control of such epidemic situations. Food-borne outbreaks and their related dynamics may lead to a critical burden of disease and an eventual capacity overload of the medical care system. Possible difficulties in the microbiological diagnostics of new or(More)
