1 State Key Laboratory of Pathogen and Biosecurity, Beijing Institute of Microbiology and Epidemiology , Beijing, China .

Tick-borne encephalitis virus (TBEV) can cause fever, headache, neurological disorders, and/or peripheral flaccid paralysis; therefore, it is a major threat to public health. A rapid, sensitive, and simple method for detecting anti-TBEV antibodies is needed urgently to determine infection and for vaccine evaluation. Here, a luciferase-based immunocomplex assay system (Luc-IC) was developed to detect TBEV antibodies. Read More

Dog survey in Russian veterinary hospitals: tick identification and molecular detection of tick-borne pathogens.

Parasit Vectors 2018 Nov 14;11(1):591. Epub 2018 Nov 14.

Institute of Systematics and Ecology of Animals, Siberian Branch of the Russian Academy of Sciences, Frunze, 11, 630091, Novosibirsk, Russia.

Background: Species of Canidae in Russia can be infested with up to 24 different tick species; however, the frequency of different tick species infesting domestic dogs across Russia is not known. In addition, tick-borne disease risks for domestic dogs in Russia are not well quantified. The goal of this study was to conduct a nationwide survey of ticks collected from infested dogs admitted to veterinary clinics in Russian cities and to identify pathogens found in these ticks.

A bite so sweet: the glycobiology interface of tick-host-pathogen interactions.

Parasit Vectors 2018 Nov 14;11(1):594. Epub 2018 Nov 14.

Institute of Parasitology, Biology Centre, Czech Academy of Sciences, Branišovská 31, CZ-37005, České Budějovice, Czech Republic.

Vector-borne diseases constitute 17% of all infectious diseases in the world; among the blood-feeding arthropods, ticks transmit the highest number of pathogens. Understanding the interactions between the tick vector, the mammalian host and the pathogens circulating between them is the basis for the successful development of vaccines against ticks or the tick-transmitted pathogens as well as for the development of specific treatments against tick-borne infections. A lot of effort has been put into transcriptomic and proteomic analyses; however, the protein-carbohydrate interactions and the overall glycobiology of ticks and tick-borne pathogens has not been given the importance or priority deserved.

Characterization of tick organic anion transporting polypeptides (OATPs) upon bacterial and viral infections.

Parasit Vectors 2018 Nov 14;11(1):593. Epub 2018 Nov 14.

Department of Biological Sciences, Old Dominion University, Norfolk, VA, USA.

Background: Ixodes scapularis organic anion transporting polypeptides (OATPs) play important roles in tick-rickettsial pathogen interactions. In this report, we characterized the role of these conserved molecules in ticks infected with either Lyme disease agent Borrelia burgdorferi or tick-borne Langat virus (LGTV), a pathogen closely related to tick-borne encephalitis virus (TBEV).

Results: Quantitative real-time polymerase chain reaction analysis revealed no significant changes in oatps gene expression upon infection with B. Read More
