Here, we report the draft genome sequences of isolates of Anaplasma phagocytophilum, Anaplasma marginale, and Anaplasma ovis The genomes of A. phagocytophilum (human), A. marginale (cattle), and A. ovis (goat) isolates from the United States were sequenced and characterized. This is the first report of an A. ovis genome sequence.

The genus Anaplasma (Rickettsiales: Anaplasmataceae) includes obligate tick-transmitted intracellular organisms, Anaplasma phagocytophilum and Anaplasma marginale that multiply in both vertebrate and tick host cells. Recently, we showed that A. marginale affects the expression of tick genes that are involved in tick survival and pathogen infection and multiplication. However, the gene expressio...

Anaplasma species of the family Anaplasmataceae, order Rickettsiales are tick-borne organisms that can cause disease in animals and humans. In Japan, all recognized species of Anaplasma (except for Anaplasma ovis) and a potentially novel Anaplasma sp. closely related to Anaplasma phagocytophilum have been reported. Most of these detected tick-borne pathogens are believed to be lowly pathogenic ...

Anaplasma marginale and A. phagocytophilum are intracellular rickettsial pathogens causing bovine anaplasmosis and human granulocytic anaplasmosis, respectively. Effective vaccines for the control of anaplasmosis are not available despite attempts using different approaches, such as attenuated strains, infected erythrocyte and tick cell-derived purified antigens. Recent reports demonstrated tha...

The genus Anaplasma is an obligated intracellular Rickettsia and among its species, Anaplasma phagocytophilum (A. phagocytophilum) is a zoonotic agent that infects host neutrophils. The aim of this study was molecular detection of A. phagocytophilum infection based on MSP4 gene in owned and stray dogs in Tehran, capital of Iran. One hundred and fifty blood sampl...

Major surface protein 5 (Msp5) of Anaplasma marginale is highly conserved in the genus Anaplasma and the antigen used in a commercially available competitive enzyme-linked immunosorbent assay (cELISA) for serologic identification of cattle with anaplasmosis. This study analyzes the degrees of conservation of Msp5 among various isolates of Anaplasma phagocytophilum and the extent of serologic cr...

Canine DNA samples from South Africa were found to contain 16S rRNA gene nucleotide and citrate synthase gene nucleotide and deduced amino acid sequences that were most similar to Anaplasma phagocytophilum: 98%, 66%, and 69% similarity, respectively. This suggests that a new Anaplasma species closely related to A. phagocytophilum occurs in Africa.

Granulocytic anaplasmosis is a tick-borne, zoonotic disease caused by an obligate intracellular granulocytotropic bacterium, Anaplasma phagocytophilum. A. phagocytophilum and other Anaplasma and Ehrlichia spp. have been variably implicated with an associated hematologic alteration, platelet dysfunction, that can result in potentially serious clinical sequelae including hemorrhage. The objective...

Anaplasma platys and A. phagocytophilum are tick-borne pathogens that parasitize platelets and neutrophils, respectively, of humans and animals. The former is the etiological agent of canine cyclic thrombocytopenia, while the latter is that of canine granulocytic anaplasmosis. This work involved the detection and identification of Anaplasma species in blood samples from dogs in Colombia, using ...

SUMMARY The occurrence of Anaplasma phagocytophilum was investigated in spleen and serum samples from Swedish moose (Alces alces) in southern Sweden (island and mainland). Samples were analysed for presence of A. phagocytophilum DNA by real-time PCR (n = 263), and for Anaplasma antibodies with ELISA serology (n = 234). All serum samples had antibodies against A. phagocytophilum. The mean DNA-ba...
