“…Since the 16th and 17th centuries, R. microplus has proven its invasive potential by spreading from its original habitats in South and South-East Asia to Africa and the Americas via the transport of infested livestock (Barre and Uilenberg 2010). In Western Africa, established R. microplus populations have been found in Côte d'Ivoire, Benin, Togo, Burkina Faso and Mali ( Madder et al 2007;Adakal et al 2013), but the presence of this tick species has hitherto not been reported in Nigeria (Reye et al 2012;Lorusso et al 2013). R. microplus has a high competence in transmitting Babesia bovis and Babesia bigemina, Anaplasma marginale and Borrelia theileri to cattle, causing bovine babesiosis, anaplasmosis and spirochaetosis (Walker et al 2003).…”

Key words:Nigeria; Rhipicephalus microplus; cattle tick; Amblyomma variegatum, cattle Rhipicephalus (Boophilus) microplus ("Cattle tick") is an important vector of livestockdiseases in (sub)-tropical regions, resistant to common acaricides. In 2013, 234 feeding ticks were collected in Ogun State in south-western Nigeria from cattle herds (121 cows) and the vegetation (n=15). Molecular species identification based on 16S rRNA revealed that 42.3% of feeding ticks were R. microplus (n=99), 41% Amblyomma variegatum (n=96) and less than 1% R. annulatus and R. geigyi. These results were confirmed using Cytochrome C oxidase I sequencing. 15.8% ticks (n=37) that clustered separately (cluster I) could not be identified as a result of missing reference sequences. R. microplus was found (for the first time in Nigeria) in 17 of 21 herds (80.9%). Cluster 1 ticks were found in about half of the herds (47.6%). The majority of ticks collected from the vegetation were R. microplus (46.7%, n=7). Only immature R. microplus were collected from the vegetation (85.7%, larvae; 14% nymphs). Verifiable evidence suggests that R. microplus has successfully present established a viable population in south-western Nigeria probably engendered by uncontrolled trade and movement of livestock across Borders. The discovery of this species in Nigeria must have occurred only recently, as R. microplus was not priorly found the same area in 2009 or in central Nigeria in 2010. The displacement of indigenous tick species with no vector competence for B. bovis (e.g. R. decoloratus, R. evertsi) by the competent vector species R. microplus leads to an increased risk of infection for cattle.

Abstract. The study of relapsing fever borreliae in Africa has long suffered from the use of non-specific laboratory tools for the direct detection of these spirochetes in clinical and vector specimens. Accordingly, Borrelia hispanica, Borrelia crocidurae, Borrelia duttonii, and Borrelia recurrentis have traditionally been distinguished on the basis of geography and vector and the unproven hypothesis that each species was exclusive to one vector. The recent sequencing of three relapsing fever Borrelia genomes in our laboratory prompted the development of more specific tools and a reappraisal of the epidemiology in Africa. Five additional potential species still need to be cultured from clinical and vector sources in East Africa to further assess their uniqueness. Here, we review the molecular evidence of relapsing fever borreliae in hosts and ectoparasites in Africa and explore the diversity, geographical distribution, and vector association of these pathogens for Africans and travelers to Africa.

Obrigada por ter acreditado no que eu podia oferecer e pela liberdade que tive ao longo dessa pesquisa.Obrigada à CAPES pelo apoio financeiro para que eu pudesse me dedicar exclusivamente a pesquisa e para que eu realizasse o doutorado viii sanduíche na Universidade de Bristol. Obrigada à FAPDF por financiar a apresentação desse projeto em congressos internacionais.Por fim, sou muito grata ao que o doutorado me proporcionou:conhecimento, descobertas, oportunidades e novos horizontes! Espero que esse conteúdo possa contribuir de alguma forma àqueles que se interessam pelas hemoplasmoses. ' (CMhp) are the most prevalent. The aims of the present study were to determine the occurrence and the phylogeny of haemoplasma species from cats in Brasilia and surrounding cities and from dogs in Nigeria, Africa; and assess weather any correlation existed between haemoplasma infection and haematological abnormalities. Blood samples were collected from 451 cats in different origins of Brasília, DF and from 246 dogs from Jos, Plateau State, Nigeria; submitted to erythrocyte evaluation and DNA extraction for PCR analysis and sequencing. In the cats study, haemoplasmas were found in 13.8% of 432 cats. CMhm was the most prevalent species (in 13.8% of cats), followed by Mhf (11.1%) and CMt (4.4%). Over 80% of haemoplasma-infected cats harboured two or more feline haemoplasma species: 7.1% of cats were coinfected with Mhf/CMhm, 0.4% with CMhm/CMt and 3.9% with Mhf/CMhm/CMt. Male gender was significantly associated with haemoplasma infections. No association was found between qPCR haemoplasma status and haematological variables, however CMhm relative copy nu...
