    Physiological, but not fitness, effects of two interacting haemoparasitic infections in a wild rodent.
    Int J Parasitol 2018 May 22;48(6):463-471. Epub 2018 Feb 22.
    School of Life Sciences, University of Nottingham, Nottingham NG7 2RD, UK.
    In contrast to the conditions in most laboratory studies, wild animals are routinely challenged by multiple infections simultaneously, and these infections can interact in complex ways. This means that the impact of a parasite on its host's physiology and fitness cannot be fully assessed in isolation, and requires consideration of the interactions with other co-infections. Here we examine the impact of two common blood parasites in the field vole (Microtus agrestis): Babesia microti and Bartonella spp. Read More

    Molecular diagnosis of skin infections using paraffin-embedded tissue - review and interdisciplinary consensus.
    J Dtsch Dermatol Ges 2018 Feb;16(2):139-147
    Institute of Microbiology - Clinical Microbiology, Immunology, and Hygiene, University Medical Center and Friedrich Alexander University Erlangen-Nuremberg, Erlangen, Germany.
    Nucleic acid amplification techniques (NATs), such as PCR, are highly sensitive and specific methods that have become valuable supplements to culture and serology in the diagnosis of infectious disorders. However, especially when using formalin-fixed and paraffin-embedded tissue, these techniques are associated with both false-negative and false-positive results, a pitfall that is frequently misjudged. Representatives of the German Society of Hygiene and Microbiology (DGHM) and the German Society of Dermatology (DDG) therefore set out to develop a consensus - in the form of a review article - on the appropriate indications for NATs using paraffin-embedded tissue, its contraindications, and the key points to be considered in the pre- and post-analytical phase.

    Wild-living rodents are important hosts for zoonotic pathogens. Bartonella infections are widespread in rodents; however, in Slovakia, knowledge on the prevalence of these bacteria in small mammals is limited. We investigated the prevalence and diversity of Bartonella species in the spleens of 640 rodents of six species (Apodemus flavicollis, Apodemus sylvaticus, Myodes glareolus, Microtus arvalis, Microtus subterraneus, and Micromys minutus) and in the European mole (Talpa europaea) from three different habitat types in south-western and central Slovakia.
