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. -

Passive Surveillance in Maine, an Area Emergent for Tick-Borne Diseases
VECTOR-BORNE DISEASES,SURVEILLANCE,PREVENTION Passive Surveillance in Maine, an Area Emergent for Tick-Borne Diseases PETER W. RAND,1,2 ELEANOR H. LACOMBE,1 RICHARD DEARBORN,3 BRUCE CAHILL,1 SUSAN ELIAS,1 CHARLES B. LUBELCZYK,1 4 1 GEOFF A. BECKETT, AND ROBERT P. SMITH, JR. J. Med. Entomol. 44(6): 1118Ð1129 (2007) ABSTRACT In 1989, a free-of-charge, statewide tick identiÞcation program was initiated in Maine, 1 yr after the Þrst Ixodes scapularis Say (ϭI. dammini Spielman, Clifford, Piesman & Corwin) ticks were reported in the state. This article summarizes data from 18 continuous years of tick submissions during which Ͼ24,000 ticks of 14 species were identiÞed. Data provided include tick stage, degree of engorgement, seasonal abundance, geographical location, host, and age of the person from whom the tick was removed. Maps depict the distributions of the three major species submitted. I. scapularis emerged Þrst along the coast, and then it advanced inland up major river valleys, Dermacentor variabilis Say slowly expanded centrifugally from where it was initially reported in southwestern Maine, and the distribution of long-established Ixodes cookei Packard remained unchanged. Submis- sions of nymphal I. scapularis closely correlated with reported Lyme diseases cases at the county level. Annual ßuctuations of nymphal submissions in Maine correlated with those of Lyme disease cases for New England, supporting the possibility of a regional inßuence on tick abundance. More ticks were removed from people Յ14 and Ն30 yr of age, and their degree of engorgement was greatest in people Յ20 yr of age and progressively increased in people Ն30 yr of age. -

The pathogenicity of Babesia parasites for cattle is determined by the interaction with the host immune system and the presence of the parasite’s virulence genes. A Babesia bigemina strain that has been maintained under a microaerophilic stationary phase in in vitro culture conditions for several years in the laboratory lost virulence for the bovine host and the capacity for being transmitted by the tick vector. In this study, we compared the virulome of the in vitro culture attenuated Babesia bigemina strain (S) and the virulent tick transmitted parental Mexican B. bigemina strain (M). Preliminary results obtained by using the Basic Local Alignment Search Tool (BLAST) showed that out of 27 virulence genes described Citation: Sachman-Ruiz, B.; Lozano, and analyzed in the B. -

A study on tick College Ernakulam Kerala- vectors of Wayanad district confirmed the presence of larval and nymphal Haemaphysalis spinigera, the 682011, India. chief vector of KFD in the forest pastures of Pulppally area. But in other sites viz Kalpetta and Mananthavady its prevalence was found to be low. Presence of tick species like Haemaphysalis bispinosa, Haemaphysalis spinigera, Amblyomma integrum. and Boophilus(Rhipicephalus) annulatus. was also noticed from the host animals surveyed. Keywords: Kyasanur Forest Disease, Ixodid ticks, Ectoparasite, Haemaphysalis Kyasanur Forest Disease (KFD) 1. Introduction Kyasanur Forest Disease (KFD), also referred to as monkey fever is an infectious bleeding disease in monkey and human caused by a highly pathogenic virus called KFD virus. It is an acute prostrating febrile illness, transmitted by infective ticks, especially, Haemaphysalis spinigera. Later KFD viruses also reported from sixteen other species of ticks. Rodents, Shrews, Monkeys and birds upon tick bite become reservoir for this virus. This disease was first reported from the Shimoga district of Karnataka, India in March 1955. Common targets of the virus among monkeys are langur (Semnopithecus entellus) and bonnet monkey (Macaca radiata). -

Expansion of Tick-Borne Rickettsioses in the World
microorganisms Review Expansion of Tick-Borne Rickettsioses in the World Mariusz Piotrowski * and Anna Rymaszewska Institute of Biology, University of Szczecin, 70-453 Szczecin, Poland; [email protected] * Correspondence: [email protected] Received: 24 September 2020; Accepted: 25 November 2020; Published: 30 November 2020 Abstract: Tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus Rickettsia. These infections are among the oldest known diseases transmitted by vectors. In the last three decades there has been a rapid increase in the recognition of this disease complex. This unusual expansion of information was mainly caused by the development of molecular diagnostic techniques that have facilitated the identification of new and previously recognized rickettsiae. A lot of currently known bacteria of the genus Rickettsia have been considered nonpathogenic for years, and moreover, many new species have been identified with unknown pathogenicity. The genus Rickettsia is distributed all over the world. Many Rickettsia species are present on several continents. The geographical distribution of rickettsiae is related to their vectors. New cases of rickettsioses and new locations, where the presence of these bacteria is recognized, are still being identified. The variety and rapid evolution of the distribution and density of ticks and diseases which they transmit shows us the scale of the problem. This review article presents a comparison of the current understanding of the geographic distribution of pathogenic Rickettsia species to that of the beginning of the century. Keywords: Tick-borne rickettsioses; Tick-borne diseases; Rickettsiales 1. Introduction Tick-borne rickettsioses are caused by obligate intracellular Gram-negative bacteria belonging to the spotted fever group (SFG) of the genus Rickettsia.
