Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne disease characterized by fever, thrombocytopenia and diarrhea. SFTS was firstly reported in Korea in 2013 but its seroprevalence in the country has yet to be investigated. Here, we investigate the seroprevalence of SFTS in a Korean population. A cross-sectional study was conducted on patients who had their sera tested for various reasons at a tertiary university hospital on particular days in May 2015. This study was conducted in a tertiary hospital in southeastern Korea...

INTRODUCTION: Babesiosis is an emerging tick-borne disease (TBD) caused by Babesia microti, an intracellular parasite of red blood cells. Currently, it is the highest ranked pathogen transmitted by blood transfusion. Most healthy individuals infected with B. microti are asymptomatic, but may be at risk for chronic infection. Similar to Lyme disease transmitted by Borrelia burgdorferi, B. microti is spread by Ixodes scapularis ticks. The rate of coinfection with these TBDs in humans is unclear as most studies have focused their prevalence in ticks or rodent reservoirs...

Anaplasmataceae family members include vector-borne bacteria of veterinary importance that may also affect humans. Ehrlichia canis and Anaplasma platys are the main members of this family detected in dogs worldwide. In Uruguay there are not many published studies on tick-borne pathogens affecting dogs, the only haemoparasite molecularly confirmed in dogs, is the piroplasm Rangelia vitalii. The aim of the present work was to detect the presence of A. platys and E. canis in dogs and dogs-associated ticks of two localities in Northwestern Uruguay...

Environmental and bio-ecological changes, some administrative and political mistakes, and global warming seriously affect the behaviors of ticks in Turkey and globally. The global public sensitivity toward tick infestations has increased along with increases in tick-borne diseases (TBDs). Recently, the World Health Organization (WHO) developed a new political concept, "One Health," for specific struggle strategies against tick infestations and TBDs. To highlight the importance of the issue, the WHO had declared the year 2015 for vector-borne diseases and adopted the slogan "small bites big threat"...

Ixodes ricinus, a common tick in Europe, transmits severe tickborne pathogens (TBPs). In Sweden, both prevalence and incidence of tick-borne infections have increased during the last few decades, and a majority of the cases is reported from the area around Stockholm. Among ticks, transmission of TBPs involves co-feeding of susceptible larvae or nymphs with infected ticks on the same host. Seasonal synchrony of immature stages and total tick abundance are important factors for the probability of horizontal transmission of TBPs...

World-wide concern over emerging vector-borne diseases has increased in recent years for both animal and human health. In the United Sates, concern about vector-borne diseases in canines has focused on Lyme disease, anaplasmosis, ehrlichiosis, and heartworm which infect domestic and wild canids. Of these diseases, Lyme and anaplasmosis are also frequently diagnosed in humans. Gray wolves (Canis lupus) recolonized Wisconsin in the 1970s, and we evaluated their temporal and geographic patterns of exposure to these four vector-borne diseases in Wisconsin as the population expanded between 1985 and 2011...

The Southeast region of Portugal, particularly the Guadiana valley, is currently the reintroduction territory of Lynx pardinus (Iberian lynx), one of the most endangered felids in the world that is only found in the Iberian Peninsula. Over the last century, populations have declined, placing L. pardinus at extremely high risk of extinction in the wild and relying on reintroduction projects. Among the aspects taken into account in the establishment of new populations is the sanitary status of the selected habitats, especially concerning infectious diseases, including tick-borne pathogens (TBPs)...

Anaplasma marginale is a devastating tick-borne pathogen causing anaplasmosis in cattle and results in significant economic loss to the cattle industry worldwide. Currently, there is no widely accepted vaccine against A. marginale. New generation subunit vaccines against A. marginale, which are much safer, more efficient and cost-effective, are in great need. The A. marginale outer membrane protein VirB9-1 is a promising antigen for vaccination. We previously have shown that soluble recombinant VirB9-1 protein can be expressed and purified from Escherichia coli and induce a high level of humoral and cellular immunity in mice...

Severe fever with thrombocytopenia syndrome bunyavirus (SFTSV) has been identified as the etiological agent causing severe fever with thrombocytopenia syndrome (SFTS). SFTSV was reported in recent years as a newly emerging tick-borne virus in China, Japan and South Korea and is a novel member of the genus Phlebovirus, family Bunyaviridae, which is suspected to be transmitted by the tick Haemaphysalis longicornis. The genetic diversity and evolutionary relationships between geographically distributed SFTSV strains are currently unclear...

Tick-borne encephalitis (TBE) is a potentially lethal neuroinfection in humans, caused by TBE virus (TBEV). Currently, there are no approved therapeutic agents to treat TBE. Previously, it was suggested that application of high dose intravenous immunoglobulin (IVIG) may pose potentially successful treatment for severe cases of TBE. In this study, we determined the titers of TBEV-neutralizing antibodies in two IVIG lots originating from the same manufacturer, and tested their ability to treat a lethal TBEV-infection in a mouse model...

Livestock, especially cattle, play a paramount role in agriculture production systems, particularly in poor countries throughout the world. Ticks and tick-borne diseases (TBDs) have an important impact on livestock and agriculture production in sub-Saharan Africa. The authors review the most common methods used for the control of ticks and TBDs. Special emphasis is given to the direct application of acaricides to the host animals. The possible environmental and public health adverse effects (i.e., risks for the workers, residues in the environment and in food products of animal origin) are mentioned...
