CardinaleAbstractTick-borne diseases (TBD) occur in many temperate countries and are economically important in most tropical and subtropical areas, affecting dairy and beef cattle, as well as small ruminants. Four major tick-borne diseases have been detected in eastern and southern Africa: East Coast fever (ECF) caused by Theileria parva, Theiler 1904, anaplasmosis caused by either Anaplasma marginale, Theiler 1910, Anaplasma centrale, Theiler 1911, and Anaplasma ovis, Bevan 1912, babesiosis caused by Babesia bovis, Babes 1988 and Babesia bigemina, Smith &Kilborne 1893, and heartwater caused by Ehrlichia ruminantium Cowdry 1925. A cross-sectional survey was undertaken to determine the antibody prevalence of these TBDs and to identify the risk factors for TBD infections in the Union of the Comoros. In 2016 and 2017, 903 individual animal serum samples were collected from 429 separate farms, where the farmers answered individual questionnaires. The antibody prevalence of anaplasmosis, babesiosis (B. bigemina) and heartwater was determined by enzyme-linked immunosorbent assays (ELISA) and the antibody prevalence of ECF was assessed using an immunofluorescence antibody test (IFAT). The relationship between TBD seroposi...

In this study, we applied complementary in silico approaches to modeling how Anaplasma phagocytophilum infection modulates tick vector regulome. This proof-of-concept research provided support for the use of network analysis in the study of regulome response to infection, resulting in new information on tick-pathogen interactions and potential targets for developing interventions for the control of tick infestations and pathogen transmission. Deciphering the precise nature of circuits that shape the tick regulome in response to pathogen infection is an area of research that in the future will advance our knowledge of tick-...

Abstract Climate warming and other environmental changes have contributed to the expansion of the range of several tick species into higher latitudes in North America. As temperatures increase in Canada, the environment becomes more suitable for ticks and the season suitable for tick activity lengthens, so tick-borne diseases are likely to become more common in Canada. In addition to Lyme disease, four other tick-borne diseases (TBDs) have started to emerge and are likely to increase: Anaplasmosis; Babesiosis; Powassan virus; and Borrelia miyamotoi disease. Increased temperature increases the survival and activity...

Tick-borne encephalitis (TBE) is one of eight zoonoses carried by ticks in Norway (the others are Anaplasmosis, Babesiosis, Louping ill, Lyme borreliosis, Relapsing fever, Rickettsial spotted fever and Tularemia).  As displayed in the following graphs, rates of human TBE are considerably lower than those of other tick-borne diseases in Norway, and below TBE rates reported by neighboring countries.

This study was conducted to determine the level of co-infection with protozoan pathogens (Theileria spp. and Babesia spp.) and rickettsial pathogens (A. marginale and A. phagocytophilum) in cattle in central Russia. Blood samples were examined with real time polymerase chain reaction (RT-PCR) for A. marginale and A. phagocytophilum, and by amplifying the V4 hypervariable region of the 18S rRNA gene, followed by cloning, DNA sequencing, and phylogenetic analyses, for Babesia and Theileria species. In total 67% of examined blood samples were positive for Theileria spp. or A. marginale, and 19% of the animals were co-infected...

This study provides basic knowledge that is necessary to initiate Kyasanur Forest Disease (KFD) prevention programs in these areas. Ticks were sampled from Wayanad districts of Kerala from domestic animals and identified morphologically. A total of 195 cattle searched, in which 168 (86.15%) cattle were infested with ticks and a total of 3633 ticks comprising three genera and seven species were collected,Rhipicephalus microplus (52.71%) was prevalent species followed byHaemaphysalis bispinosa (16.9%),Rhipicephalus decoloratus (15.77%),Haemaphysalis turturis (11.42%),Rhipicephalus sanguineus (1.32%),Amblyomma integrum (1.15%...

(CBS News) – New government research shows that tickborne diseases like Lyme disease continue to rise. The report from the Centers for Disease Control and Prevention finds that in 2017, state and local health departments reported a record number of cases of illnesses spread by ticks. Cases of Lyme disease, Powassan virus; spotted fever rickettsiosis, including Rocky Mountain spotted fever, anaplasmosis, ehrlichiosis, babesiosis and tularemia all increased last year. The CDC said there were 59,349 confirmed cases of tickborne diseases in 2017, up from 48,610 in 2016. In past years, h...

This study sought to detect and characterize hemoparasites among farms in acaricide-failure hotspots of central as compared to the acaricide-failure naïve areas in eastern Uganda. Nested PCR assays were performed to determine the prevalences of Babesia bovis, Babesia bigemina, Theileria parva, and Anaplasma marginale in cattle blood samples sourced from randomly selected farms. Randomly selected isolates were sequenced to determine the genetic diversity of the parasites using the following marker genes: B. bovis spherical body protein 4, B. bigemina rhoptry-associated protein 1a, T. parva 104 kDa microneme-rhoptry a...
