OBJECTIVE
Human granulocytic anaplasmosis, former ehrlichiosis, is a tick-borne zoonosis of increasing recognition. The aim of the study was: 1) to assess the prevalence of Anaplasma phagocytophilum infection in Ixodes ricinus ticks collected in recreational forests in Bialystok vicinity, the
Sera of 500 inhabitants of north-eastern Poland, 450 suspected for Lyme borreliosis and 50 blood donors (control group), were analysed for the presence of IgG antibodies against Anaplasma phagocytophilum, the causative agent of human anaplasmosis (HA), known so far as human granulocytic ehrlichiosis
Anaplasma phagocytophilum DNA was detected by real-time PCR, which targeted the msp2 gene, in 2.9% of questing Ixodes ricinus ticks (adults and nymphs; n = 2,862), collected systematically from selected locations in Bavaria, Germany, in 2006. Prevalence was significantly higher in urban public parks
Anaplasma phagocytophilum are transmitted by Ixodes spp. ticks and have become one of the most common and relevant tick-borne pathogens due to their impact on human and animal health. Recent results have increased our understanding of the molecular interactions between Ixodes scapularis and A.
Anaplasma phagocytophilum and spotted fever group Rickettsia are obligate intracellular Gram-negative tick-borne bacteria, among which several may cause clinical infections in humans. Several Rickettsia spp. and A. phagocytophilum are transmitted in Europe by Ixodes ricinus, the most common tick
Ticks are vectors of several microorganisms responsible for infectious diseases in human and animals, such as Anaplasma phagocytophilum and Coxiella burnetii. In this study, we investigated the prevalence of these two bacteria in 62 889 Ixodes ricinus ticks in selected regions
Human granulocytic anaplasmosis is increasingly being recognized in the United States and Europe. Ixodes ricinus tick is considered the primary vector of the causative pathogen, Anaplasma phagocytophilum, in Europe. Although previous studies in humans support the presence of A. phagocytophilum in
Our aim was to identify variants of Anaplasma phagocytophilum 16S rRNA gene sequences among products amplified from Ixodes ricinus collected in La Rioja, Spain. A. phagocytophilum AP-variant 1, reported as non-pathogenic, was detected in 12 samples (two adults and ten nymphs). This finding could
Ticks (Acari: Ixodida) are vectors and/or reservoirs of many pathogens, i.e. <i>Borrelia burgdorferi</i> sensu lato, <i>Anaplasma phagocytophilum</i> and <i>Babesia microti</i>. These pathogens are ethiological agents of such diseases as Lyme In the suburban and urban forests in the cities of Gdansk, Sopot and Gdynia (northern Poland), Ixodes ricinus ticks should be considered as the vector of pathogenic microorganisms that may cause significant diseases in wild and domestic animals and humans. These microorganisms include etiologic
Ixodes ricinus is a vector of pathogens that cause many diseases in Europe and Slovenia: tick-borne encephalitis (TBE), anaplasmosis, borreliosis, babesiosis and others. The risk for contracting these diseases depends strongly on the density of the infected questing ticks and many studies have
Ticks are important vectors of disease for both humans and animals. In Europe, Lyme borreliosis is the most abundant tick-borne human disease, whereas anaplasmosis, or tick-borne fever, is the most widespread tick-borne infection in domestic animals. However, knowledge about the prevalence of the
Our objectives were to investigate the presence of Anaplasma spp. infection in red deer, wild boars, and Ixodes ricinus removed from deer surveyed in La Rioja, as well as to analyze the presence of Anaplasma spp. in I. ricinus from different Spanish regions--ours included. A total of 21 deer and 13
Anaplasma phagocytophilum is the causative agent of an emerging tick-borne disease, human granulocytic anaplasmosis. While the bacterium has been reported from questing ticks in neighboring Sweden, Norway and Russia, the few surveys regarding questing ticks in Finland have thus far been negative. In
