A 2-year-old male Jindo dog was presented to a local veterinary clinic for anorexia, lethargy, edema around neck, and vomiting. Based on the clinical history, physical examination, hematology, blood chemistry, serology, and PCR, the dog was diagnosed with canine granulocytic anaplasmosis (CGA). PCR and phylogenetic analyses targeting the 16S rRNA, groEL, and msp2 genes of Anaplasma phagocytophilum revealed that the A. phagocytophilum identified in this study subgrouped into alanine and USA groups according to the groEL and msp2 gene sequences, respectively...

Vector-borne diseases are among major health constraints of small ruminant in Ethiopia. While various studies on single vector-borne diseases or presence of vectors have been conducted, no summarized evidence is available on the occurrence of these diseases and the related vectors. This systematic literature review provides a comprehensive summary on major vectors and vector-borne diseases in small ruminants in Ethiopia. Search for published and unpublished literature was conducted between 8th of January and 25th of June 2015...

BACKGROUND: There has been an emergence and expansion of tick-borne diseases in Europe, Asia and North America in recent years, including Lyme disease, tick-borne encephalitis and human anaplasmosis. The primary vectors implicated are hard ticks of the genus Ixodes. Although much is known about the host response to these bacterial and viral pathogens, there is limited knowledge of the cellular responses to infection within the tick vector. The bacterium Anaplasma phagocytophilum is able to bypass apoptotic processes in ticks, enabling infection to proceed...

Bovine anaplasmosis is a tick-borne disease, mainly caused by Anaplasma marginale and A. centrale and is distributed in tropical and sub-tropical areas. This study aimed to characterise A. marginale and A. centrale from African buffaloes in Kruger National Park (KNP), South Africa, using the DNA sequences of the genes coding for major surface protein (msp1β) and heat shock protein (groEL), respectively. A total of 747 blood samples were collected from February 2014 to August 2016 from African buffaloes kept in KNP, and DNAs were tested using a molecular-phylogenetic approach...

BACKGROUND: There has been a growing interest in camel anaplasmosis due to its recent emergence in this reservoir species and concerns for its zoonotic potential. The epidemiology of anaplasmosis in camels therefore remains poorly understood mostly because camels belong to marginalised poor and often transhumant populations whose interests are largely neglected. Most studies of anaplasmosis in camels have relied on microscopy and serology for diagnosis and only three studies, undertaken in Tunisia, Saudia Arabia and China, have used molecular diagnostics...

Borrelia miyamotoi (Bm) is a recently emerging bacterial agent transmitted by several species of ixodid ticks. Diagnosis of Bm infection can be challenging, as the organism is not easily cultivable. We have developed and validated a multiplex real-time PCR to simultaneously identify Bm infection and the agents causing human granulocytic anaplasmosis and human monocytic ehrlichiosis, Anaplasma phagocytophilum and Ehrlichia chaffeensis, respectively. The assay is 100% specific; highly sensitive, detecting 11 gene copies of Bm DNA in both whole blood and cerebral spinal fluid; and provides rapid results in less than two hours...

Anaplasma phagocytophilum is a zoonotic pathogen and the causative agent of human granulocytic anaplasmosis (HGA) in humans and tick-borne fever in various kinds of animals. In the present study, a loop-mediated isothermal amplification (LAMP) assay for rapid detection of A. phagocytophilum was developed using primers specific to 16S rRNA gene of this organism. The LAMP assay was performed at 65 C for 60 min and terminated at 80 C for 10 min. The optimal reaction conditions, under which no cross-reaction was observed with other closely related tick borne parasites (Anaplasma bovis, Anaplasma ovis, Theileria luwenshuni, Babesia motasi and Schistosoma japonicum) was established...

Accurate diagnosis of animal and zoonotic diseases, such as granulocytic anaplasmosis, is crucial to estimate risk during control programs. In this study, 16S rRNA nested PCR and RFLP assay were combined to investigate the presence of Anaplasma phagocytophilum and genetically related strains (namely A. phagocytophilum-like 1 and 2) in 936 Tunisian ruminants. By using this method, A. phagocytophilum was not detected in any of the tested animals, while A. phagocytophilum-like 1 and A. phagocytophilum-like 2 were detected at variable prevalence rates in sheep, goats and cattle at coinfection rates respectively of 3...

Arthropods transmit diverse infectious agents; however, the ways microbes influence their vector to enhance colonization are poorly understood. Ixodes scapularis ticks harbor numerous human pathogens, including Anaplasma phagocytophilum, the agent of human granulocytic anaplasmosis. We now demonstrate that A. phagocytophilum modifies the I. scapularis microbiota to more efficiently infect the tick. A. phagocytophilum induces ticks to express Ixodes scapularis antifreeze glycoprotein (iafgp), which encodes a protein with several properties, including the ability to alter bacterial biofilm formation...

Human granulocytic anaplasmosis (HGA) is a tick-borne rickettsial zoonosis with fever, thrombocytopenia, and leukopenia. HGA has been reported in Korea in 2013 but it is uncertain how long it has existed. A retrospective study was conducted on patients who underwent bone marrow examination due to fever and cytopenia, with no clear hematologic or microbiologic causes, from 2003 through 2012. Laboratory diagnosis was made by detecting 16S rRNA genes of Anaplasma phagocytophilum from the stored blood samples. Among the 70 patients, five (7...

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 species feeding on humans in this area. The aim of this study was to evaluate the annual prevalence of Rickettsia spp. and A. phagocytophilum in I. ricinus collected from humans during three consecutive years. The mean prevalences of the infection with the investigated pathogens in I...

Ehrlichiosis and anaplasmosis are important emerging tickborne zoonoses that affect both humans and animals. Knowledge of the geographic distribution and prevalence of Ehrlichia spp. and Anaplasma phagocytophilum in Wisconsin is important information as a baseline for future comparisons. Reported human cases between 2009 and 2015 were identified using the Wisconsin Electronic Disease Surveillance System (WEDSS) and mapped by county of residence. Vector surveillance was established using ticks collected from animals by partners, including veterinary medical clinics, domestic animal shelters, and wildlife rehabilitation centers from 40 Wisconsin counties...

Anaplasma marginale causes bovine anaplasmosis, a debilitating and potentially fatal tick-borne infection of cattle. Because A. marginale is an obligate intracellular organism, its adhesins that mediate entry into host cells are essential for survival. Here, we demonstrate that A. marginale outer membrane protein A (AmOmpA; AM854) contributes to the invasion of mammalian and tick host cells. AmOmpA exhibits predicted structural homology to OmpA of A. phagocytophilum (ApOmpA), an adhesin that uses key lysine and glycine residues to interact with α2,3-sialylated and α1,3-fucosylated glycan receptors, including 6-sulfo-sialyl Lewis x...

Here, we report the molecular detection of Anaplasma phagocytophilum in shelter cats in Korea and the relationships between A. phagocytophilum gene sequences and the pathogenicity, region, and host specificity of this bacterium. Two (0.9%) out of 222 shelter cats from Seoul, Korea, yielded positive results for the A. phagocytophilum 16S rRNA, groEL, and msp2 genes. Phylogenetic analysis divided groEL gene sequences into two groups (alanine and serine), based on their nucleotide and amino acid sequences. A. phagocytophilum msp2 gene sequences were grouped per the region of isolation (Europe vs...

Ticks are able to transmit various pathogens-viruses, bacteria, and parasites-to their host during feeding. Several molecular epidemiological surveys have been performed to evaluate the risk of tick-borne pathogens in China, but little is known about pathogens circulating in ticks from eastern China. Therefore, this study aimed to investigate the presence of bacteria and parasites in ticks collected from Xuzhou, a 11258km(2) region in eastern China. In the present study, ticks were collected from domestic goats and grasses in urban districts of Xuzhou region from June 2015 to July 2016...

The importance of tick-borne diseases is increasing all over the world, including Turkey. Global warming, environmental and ecological changes and the existence of suitable habitats increase the impact of ticks and result in frequent emergence or re-emergence of tick-borne diseases (TBDs) with zoonotic characteristics. In Turkey, almost 19 TBDs have been reported in animals and men, involving four protozoa (babesiosis, theileriosis, cytauxzoonosis, hepatozoonosis), one filarial nematode (acanthocheilonemasis), ten bacterial agents (anaplasmosis, ehrlichiosis, aegyptianellosis, tick-borne typhus, Candidatus Rickettsia vini, Lyme borreliosis, tick-borne relapsing fever [TBRF], tularaemia, bartonellosis, and hemoplasmosis), and four viral infections (tick-borne encephalitis [TBE], Crimean-Congo Haemorrhagic Fever [CCHF], louping-ill [LI], and lumpy skin disease [LSD])...

Human granulocytic anaplasmosis is currently not nationally notifiable in Canada. This for the most part accounts for gross under-estimation of true incidence and prevalence of HGA and would potentially culminate in clinical missed opportunities. To the best of our knowledge, this is the first report on the seroprevalence of Anaplasma phagocytophilum in a Canadian jurisdiction with known established black-legged tick populations.
