Abstract 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 in animals in Japan although the zoonotic A. phagocytophilum has recently been reported to cause clinical signs in a dog and in humans. This review documents the studies and reports about Anaplasma spp. in Japan. Keywords: Anaplasma spp., Japan, tick-borne pathogen. Introduction A. phagocytophilum sequences [10-15]. Phylogenetic Anaplasma species are Gram-negative, obligate inferences have suggested that 2 clades exist within intracellular bacteria of the order Rickettsiales, fam- the genus Anaplasma: (1) Erythrocytic (A. -

Habitat Suitability Models: Tick Vectors • Ixodes scapularis • Amblyomma americanum • Ixodes pacificus • Amblyomma maculatum • Dermacentor andersoni • Dermacentor variabilis Background Within the United States there are several tick-borne diseases (TBD) to consider. While most are not fatal, they can be quite debilitating and many have no known treatment or cure. Within the U.S., ticks are most active in the warmer months (April to September) and are most commonly found in forest edges with ample leaf litter, tall grass and shrubs. It is important to check yourself for ticks and tick bites after exposure to such areas. Dogs can also be infected with TBD and may also bring ticks into your home where they may feed on humans and spread disease (CDC, 2014). This report contains a list of common TBD along with background information about the vectors and habitat suitability models displaying predicted geographic distributions. Many tips and other information on preventing TBD are provided by the CDC, AFPMB or USAPHC.

Ehrlichiosis is a tick-borne disease caused by Ehrlichia spp, an obligate intracellular gram-negative bacterium of the Anaplasmataceae family. In Europe, Ehrlichia canis causes canine monocytic ehrlichiosis ! (CME) The tick Rhipicephalus sanguineus is its main vector in Europe. Dogs and wild canids act as reservoirs. The disease has a subclinical, acute asymptomatic phase and chronic phase. The prognosis for chronically sick dogs is poor, ! !! The incubation period is 1-4 weeks. German Shepherds and Siberian Huskies appear to be more susceptible to clinical ehrlichiosis with more severe clinical !! presentations than other breeds. When to suspect infection? Origin / travelling history Clinical signs o Dogs that live in, originate from or have travelled to countries where the parasite is endemic are at risk. Weight loss, anorexia, lethargy, fever o Dogs in countries not currently considered endemic Bleeding disorders: petechiae/ecchymoses of the skin, mucous o o should not be considered free of risk. membranes and conjunctivas, hyphaema, epistaxis Lymphadenomegaly o How can it be confirmed? o Splenomegaly o Ocular signs: conjunctivitis, uveitis, corneal oedema Blood smear: Visualisation of intracellular bacteria on blood o Neurological signs (less common): seizures, ataxia, paresis, smears stained with Giemsa or similar.

Mitochondrial DNA Sequence Variation in Ixodes Paci®Cus (Acari: Ixodidae)
Heredity 83 (1999) 378±386 Received 20 August 1998, accepted 7 July 1999 Mitochondrial DNA sequence variation in Ixodes paci®cus (Acari: Ixodidae) DOUGLAS E. KAIN*, FELIX A. H. SPERLING , HOWELL V. DALY & ROBERT S. LANE Department of Environmental Science, Policy and Management, Division of Insect Biology, University of California at Berkeley, Berkeley, CA 94720, U.S.A. The western black-legged tick, Ixodes paci®cus, is a primary vector of the spirochaete, Borrelia burgdorferi, that causes Lyme disease. We used variation in a 355-bp DNA portion of the mitochondrial cytochrome oxidase III gene to assess the population structure of the tick across its range from British Columbia to southern California and east to Utah. Ixodes paci®cus showed considerable haplotype diversity despite low nucleotide diversity. Maximum parsimony and isolation- by-distance analyses revealed little genetic structure except between a geographically isolated Utah locality and all other localities. Loss of mtDNA polymorphism in Utah ticks is consistent with a post- Pleistocene founder event. The pattern of genetic dierentiation in the continuous part of the range of Ixodes paci®cus reinforces recent recognition of the diculties involved in using genetic frequency data to infer gene ¯ow and migration. Keywords: gene ¯ow, Ixodes paci®cus, Ixodidae, Lyme disease, mitochondrial DNA, population structure. Introduction stages of I. paci®cus each feed once and then drop from the host to moult or lay eggs under leaf litter (Peavey & The western black-legged tick, Ixodes paci®cus, is one of Lane, 1996). Eective gene ¯ow is likely to occur only the most medically important ticks in western North when there is sucient rainfall, ground cover and soil America. -

Ehrlichiosis and Anaplasmosis Are Tick-Borne Diseases Caused by Obligate Anaplasmosis: Intracellular Bacteria in the Genera Ehrlichia and Anaplasma
Ehrlichiosis and Importance Ehrlichiosis and anaplasmosis are tick-borne diseases caused by obligate Anaplasmosis: intracellular bacteria in the genera Ehrlichia and Anaplasma. These organisms are widespread in nature; the reservoir hosts include numerous wild animals, as well as Zoonotic Species some domesticated species. For many years, Ehrlichia and Anaplasma species have been known to cause illness in pets and livestock. The consequences of exposure vary Canine Monocytic Ehrlichiosis, from asymptomatic infections to severe, potentially fatal illness. Some organisms Canine Hemorrhagic Fever, have also been recognized as human pathogens since the 1980s and 1990s. Tropical Canine Pancytopenia, Etiology Tracker Dog Disease, Ehrlichiosis and anaplasmosis are caused by members of the genera Ehrlichia Canine Tick Typhus, and Anaplasma, respectively. Both genera contain small, pleomorphic, Gram negative, Nairobi Bleeding Disorder, obligate intracellular organisms, and belong to the family Anaplasmataceae, order Canine Granulocytic Ehrlichiosis, Rickettsiales. They are classified as α-proteobacteria. A number of Ehrlichia and Canine Granulocytic Anaplasmosis, Anaplasma species affect animals. A limited number of these organisms have also Equine Granulocytic Ehrlichiosis, been identified in people. Equine Granulocytic Anaplasmosis, Recent changes in taxonomy can make the nomenclature of the Anaplasmataceae Tick-borne Fever, and their diseases somewhat confusing. At one time, ehrlichiosis was a group of Pasture Fever, diseases caused by organisms that mostly replicated in membrane-bound cytoplasmic Human Monocytic Ehrlichiosis, vacuoles of leukocytes, and belonged to the genus Ehrlichia, tribe Ehrlichieae and Human Granulocytic Anaplasmosis, family Rickettsiaceae. The names of the diseases were often based on the host Human Granulocytic Ehrlichiosis, species, together with type of leukocyte most often infected. -
