Road-killed mammals provide insight into tick-borne bacterial pathogen communities within urban habitats.

Transbound Emerg Dis 2018 Sep 19. Epub 2018 Sep 19.

Department of Parasitology and Zoology, University of Veterinary Medicine Budapest, Budapest, Hungary.

Small- and medium-sized mammals play an important role in the life cycle of tick-borne pathogens in urban habitats. Our aim was to apply the general protocol, DAMA (documentation-assessment-monitoring-action), which is an integrated proposal to build a proactive capacity to understand, anticipate, and respond to the outcomes of accelerating environmental change. Here we tested whether road-killed carcasses in urban areas are useful sources of tissue and parasite samples to investigate these species' contribution to the epidemiology of vector-borne diseases.

Molecular evidence and diversity of the spotted-fever group Rickettsia spp. in small mammals from natural, suburban and urban areas of Eastern Slovakia.

Ticks Tick Borne Dis 2018 09 23;9(6):1400-1406. Epub 2018 Jun 23.

Institute of Parasitology, Slovak Academy of Sciences, Hlinkova 3, 040 01 Košice, Slovakia; Institute of Zoology, Slovak Academy of Sciences, Dúbravská cesta 9, 845 06 Bratislava, Slovakia. Electronic address:

Rickettsiae of the spotted fever group are considered as emerging pathogens; ticks, fleas and mites are known to be their vectors. However, the prevalence and species diversity of rickettsiae in small mammals and the role of these hosts in the circulation of bacteria are much less studied. During 2014-2016, a total of 250 small mammals (Apodemus agrarius, Apodemus flavicollis, Apodemus uralensis, Myodes glareolus, Crocidura leucodon, Crocidura suaveolens, Micromys minutus, Microtus arvalis, Microtus subterraneus, Neomys fodiens and Sorex minutus) were captured in natural, suburban and urban habitats of eastern Slovakia.

Geometric morphometric analyses of sexual dimorphism and allometry in two sympatric snakes: Natrix helvetica (Natricidae) and Vipera berus (Viperidae).

Zoology (Jena) 2018 08 22;129:25-34. Epub 2018 May 22.

Research Centre in Evolutionary Anthropology and Palaeoecology, School of Natural Sciences and Psychology, Liverpool John Moores University, Liverpool, UK. Electronic address:

The non-venomous grass snake (Natrix helvetica) and the venomous adder (Vipera berus) are two native species that are often found in sympatry in Great Britain and Europe. They occupy partially overlapping ecological niches and prey on small vertebrates, but use different feeding strategies. Here, we investigated the morphologies of grass snakes and adders from Dorset (UK) using two-dimensional geometric morphometrics to assess the degree of sexual dimorphism in size and shape together with the relative impact of allometry and general body dimensions on head shape.

Spotted fever rickettsiae in wild-living rodents from south-western Poland.

Parasit Vectors 2017 Sep 6;10(1):413. Epub 2017 Sep 6.

Centre for Infectious Disease Control, National Institute for Public Health and Environment, Antonie van Leeuwenhoeklaan 9, 3721 MA, Bilthoven, The Netherlands.

Background: Rickettsiae are obligate intracellular alpha-proteobacteria. They are transmitted via arthropod vectors, which transmit the bacteria between animals and occasionally to humans. So far, much research has been conducted to indicate reservoir hosts for these microorganisms, but our knowledge is still non-exhaustive. Read More

Two mice models for transferability of zoonotic bacteria via tick vector.

Acta Virol 2017;61(3):372-376

Spotted fever and typhus-related diseases caused by rickettsiae, Lyme borreliosis induced by spirochetes from Borrelia burgdorferii sensu lato complex, and Q fever evoked by Coxiella burnetii, are important zoonoses occurring worldwide. In order to study the pathogenesis of these infections, the efficacy of vaccines from the perspective of protection against the pathogens, pathogen - pathogen interactions during co-infections or pathogen-vector-host interrelationship, a suitable animal model should be established. In this study, we evaluated two mouse models - the C3H/N and Balb/c strains for susceptibility to infection and ability to transmit the pathogens via tick vector and to reveal the potential interactions between various bacterial tick-borne agents.

Hybridization patterns in two contact zones of grass snakes reveal a new Central European snake species.

Sci Rep 2017 Aug 7;7(1):7378. Epub 2017 Aug 7.

Museum of Zoology (Museum für Tierkunde), Senckenberg Dresden, A. B. Meyer Building, 01109, Dresden, Germany.

Recent studies found major conflicts between traditional taxonomy and genetic differentiation of grass snakes and identified previously unknown secondary contact zones. Until now, little is known about gene flow across these contact zones. Using two mitochondrial markers and 13 microsatellite loci, we examined two contact zones. Read More

Application of Mycorrhiza and Soil from a Permaculture System Improved Phosphorus Acquisition in Naranjilla.

Front Plant Sci 2017 19;8:1263. Epub 2017 Jul 19.

Department of Soil Sciences, Research Institute of Organic AgricultureFrick, Switzerland.

Naranjilla () is a perennial shrub plant mainly cultivated in Ecuador, Colombia, and Central America where it represents an important cash crop. Current cultivation practices not only cause deforestation and large-scale soil degradation but also make plants highly susceptible to pests and diseases. The use of arbuscular mycorrhizal fungi (AMF) can offer a possibility to overcome these problems. Read More

Impact of a freeway on the dispersal of ticks and Ixodes ricinus-borne pathogens: forested resting areas may become Lyme disease hotspots.

Acta Vet Hung 2017 06;65(2):242-252

Clinical Laboratory and Center for Clinical Studies, Vetsuisse Faculty, University of Zurich , Zurich , Switzerland.

Man-made barriers are well known for their effects on ecosystems. Habitat fragmentation, for instance, is a recognised consequence of modern-day infrastructure. The aim of the present study was to investigate the diversity and abundance of tick species, as well as the risks of acquiring tick-borne infections in habitats adjacent to a freeway. Read More

Importance of Common Wall Lizards in the Transmission Dynamics of Tick-Borne Pathogens in the Northern Apennine Mountains, Italy.

Microb Ecol 2017 11 24;74(4):961-968. Epub 2017 May 24.

Dipartimento di Scienze Veterinarie, University of Turin, Largo Braccini 2, Grugliasco Turin, Italy.

During the investigations on ticks and tick-borne pathogens (TBP) range expansion in the Northern Apennines, we captured 107 Podarcis muralis lizards. Sixty-eight animals were infested by immature Ixodes ricinus, Haemaphysalis sulcata and H. punctata. Read More

Candidatus Neoehrlichia mikurensis and Borrelia burgdorferi sensu lato detected in the blood of Norwegian patients with erythema migrans.

Ticks Tick Borne Dis 2017 08 13;8(5):715-720. Epub 2017 May 13.

Sørlandet Hospital Health Enterprise, Department of Medical Microbiology, Egsveien 100, PO-Box 416, NO-4604, Kristiansand, Norway.

The most common tick-borne human disease in Norway is Lyme borreliosis. Ticks in Norway also harbour less known disease-causing agents such as Candidatus Neoehrlichia mikurensis, Borrelia miyamotoi and Rickettsia helvetica. However, human infections caused by these pathogens have never been described in Norway. Read More
