The organisms of the Order Rickettsiales, in the families Rickettsiaceae and Anaplasmataceae, were reclassified in 2001 following phylogenetic analyses of the 16S rRNA and groESL gene sequences (Dumler and colleagues, 2001). Some Ehrlichia spp. were transferred to the Neorickettsia genus (including E. risticii) and some Ehrlichia spp., including E. phagocytophila (also called E. equi and human ...
▪ Stay in a TBE risk area ▪ Significantly reduced general condition with high fever and headaches ▪ Neurological deficits such as disturbances of consciousness and balance, paralysis of cranial nerves or extremities ▪ Evidence of TBE-specific IgM and IgG antibodies in blood ▪ Pleocytosis in CSF (normal cell count in extremely rare cases) ▪ Elevated TBE-specific antibody index at the latest 4 we...
Tick-borne lymphadenopathy (TIBOLA), also called Dermacentor-borne necrosis erythema and lymphadenopathy (DEBONEL), is defined as the association of a tick bite, an inoculation eschar on the scalp, and cervical adenopathies. We identified the etiologic agent for 65% of 86 patients with TIBOLA/DEBONEL as either Rickettsia slovaca (49/86, 57%) or R. raoultii (7/86, 8%).
The Companion Animal Parasite Council hosted a meeting to identify quantifiable factors that can influence the prevalence of tick-borne disease agents among dogs in North America. This report summarizes the approach used and the factors identified for further analysis with mathematical models of canine exposure to tick-borne pathogens.
“The biology and ecology of ticks shape the potential for the transmission of zoonotic pathogens” is a collection of research and review articles related to the study of tick-borne diseases, with a focus on the methodology to explore the basic relationships between the tick-transmitted pathogens and the environment. It is well-known that a multidisciplinary point of view is necessary in order t...
BACKGROUND Nagana (African Animal Trypanosomiasis-AAT) and tick-borne diseases (TBDs) constrain livestock production in most parts of sub-Saharan Africa. To this realisation, Uganda government set up an African trypanosomiasis (AT) control unit, which among other activities generates national tsetse control priority maps using apparent tsetse density data. Such maps underestimate mechanically t...
The Khingan Mountain region, the most important and typical natural foci of tick-borne encephalitis (TBE) in China, is the largest and northernmost forest area and the one more sensitive to climate change. Taking this region as the study area, we investigated the spatio-temporal dynamics of deciduous broadleaf forest (DBF) and its phenology changes in relation to climate change and elevation. B...
Some tick populations have increased dramatically in the past several decades leading to an increase in the incidence and emergence of tick-borne diseases. Management strategies that can effectively reduce tick populations while better understanding regional tick phenology is needed. One promising management strategy is prescribed burning. However, the efficacy of prescribed burning as a mechan...
An unexpectedly high infection rate (26.1%) of tick-borne encephalitis virus (TBEV) was identified in a herd of 257 horses of the same breed distributed among 3 federal states in Austria. Young age (p<0.001) and male sex (p=0.001) were positively associated with infection.
BACKGROUND Large regions of central and eastern Europe are recognized as areas where tick-borne encephalitis virus (TBEV) is endemic, including countries neighbouring Denmark. It is therefore timely and relevant to determine if TBEV infections occur in Denmark. This study investigates the presence of antibodies against TBEV in a cross-section of the Danish canine population to assess the level ...
