The presence of Anaplasma phagocytophilum, a tick-transmitted zoonotic pathogen, has been reported in Italy in humans and several animal species, including dogs, but data concerning its prevalence in the Italian canine population are lacking. The aim of this study was to determine the prevalence of A. phagocytophilum infection in hunting dogs which live in geographic areas of central Italy wher...
Rickettsial agents are sensed by pattern recognition receptors but lack pathogen-associated molecular patterns commonly observed in facultative intracellular bacteria. Due to these molecular features, the order Rickettsiales can be used to uncover broader principles of bacterial immunity. Here, we used the bacterium Anaplasma phagocytophilum, the agent of human granulocytic anaplasmosis, to rev...
Ferritin is a major intracellular iron storage protein and also functions as a cytoprotectant by sequestering iron to minimize the formation of reactive oxygen species. Anaplasma phagocytophilum, the causative agent of human granulocytic anaplasmosis, is an obligate intracellular bacterium that colonizes neutrophils. We have previously reported that human promyelocytic HL-60 cells infected with...
The emerging tick-borne pathogen Anaplasma phagocytophilum is under increasing scrutiny for the existence of subpopulations that are adapted to different natural cycles. Here, we characterized the diversity of A. phagocytophilum genotypes circulating in a natural system that includes multiple hosts and at least 2 tick species, Ixodes ricinus and the small mammal specialist I. trianguliceps. We ...
The main goal of our study was to determine the prevalence of Anaplasma phagocytophilum infections in wild cervids living in north-eastern part of Poland. Material used in the study was gathered between the years 2004- 2008. The blood samples from 106 red deer (Cervus elaphus), 32 sika deer (Cervus nippon hortulorum), 130 fallow deer (Dama dama) and 31 roe deer (Capreolus capreolus) were collec...
Twelve confirmed cases of equine granulocytic anaplasmosis (EGA) and five additional suspected cases, showing a compatible clinical history and specific IgG titres of 1280 or above, were recorded in the Czech Republic during the period 2002 to 2008. The diagnosis was based on clinical signs, the detection of Anaplasma phagocytophilum morulae in neutrophils in blood smears, serology and molecula...
BACKGROUND Ticks derived from cats have rarely been evaluated for the presence of pathogens. The aim of this study was to determine the prevalence of Anaplasma phagocytophilum, Bartonella spp., haemoplasma species and Hepatozoon spp. in ticks collected from cats in the UK. METHODS Five hundred and forty DNA samples extracted from 540 ticks collected from cats presenting to veterinarians in UK...
