Multiflora rose invasion amplifies prevalence of Lyme disease pathogen, but not necessarily Lyme disease risk

Forests in urban landscapes differ from their rural counterparts in ways that may alter vector-borne disease dynamics. In urban forest fragments, tick-borne pathogen prevalence is not well characterized; mitig...

Abstract Ticks are the most important vectors of human pathogens, leading to increased public health burdens worldwide. Tick-borne pathogens include viruses (e.g. tick-borne encephalitis and Powassan); bacteria, such as the causative agents of Lyme disease, spotted fever rickettsiosis and human anaplasmosis; and malaria-like protozoan parasites causing babesiosis. Tick-borne diseases are emerging due to the geographical expansion of their tick vectors, especially in the northern hemisphere. Two examples of this phenomenon are Ixodes scapularis and Amblyomma americanum, which have expanded their ranges in the USA i...

Rudenko Libor Grubhoffer Ticks are important human and animal parasites and vectors of many infectious disease agents. Control of tick activity is an effective tool to reduce the risk of contracting tick-transmitted diseases. The castor bean tick (Ixodes ricinus) is the most common tick species in Europe. It is also a vector of the causative agents of Lyme borreliosis and tick-borne encephalitis, which are two of the most important arthropod-borne diseases in Europe. In recent years, increases in tick activity and incidence of tick-borne diseases have been observed in many European countries. These increases are lin...

The distribution range of I. lividus covers Europe and Asia and they are found wherever sand martins nest. Borrelia burgdorferi sensu stricto, Borrelia garinii and Rickettsia vini have recently been detected in I. lividus ticks in Central Europe. The aim of this study was to investigate the presence of Rickettsia spp. (Rickettsiale...

der F Abstract Introduction: Despite advancements in diagnostic capabilities and the availability of effective antimicrobial agents, community-acquired infections of the central nervous system (CNS) are still associated with high mortality rates. Aim: To assess the epidemiological and clinical characteristics of community-acquired CNS infections treated in the West Pannonian region between 2010 and 2016. Method: Clinical data of 176 patients were retrospectively analysed in two age cohorts: 15 to 65 and more than 65 years of age. Results: Neuroinfections were found to be bacterial in 81, viral in 91, parasitic in ...

Cecere, Fernando Spina, Federica MonacoAbstractThe continuous flow of billions of birds between Africa and Europe creates an “ecological bridge” between physically remote areas. Migratory birds fly south from their breeding grounds during late summer/fall and fly back in spring. These movements regulate the spread of internal and ex...

This study demonstrates the effect of only simultaneous infection by B. burgdorferi and B. microti on each pathogen, immune response and on disease manifestations with respect to infection by the spirochete and the parasite. In our future studies, we will examine the overall effects of sequential infection by these pathogens on host immune responses and disease outcomes.

Seventy percent (35/50) of ticks contained at least one microorganism; 26% (9/35) contained two or more species. Several human pathogens were identified including Borrelia burgdorferi s.s. (4%), ...
