37. Assessing bovine babesiosis in Rhipicephalus (Boophilus) microplus ticks and 3 to 9-month-old cattle in the middle Magdalena region, Colombia
Babesia sp. is a protozoan hemoparasite that affects livestock worldwide. The Colombian Middle Magdalena is an enzootic region for babesiosis, but there is no previous research providing detail on its transmission cycle. This study aims to assess some Babesia sp. infection indicators in cattle and ticks from the area, by using direct microscopic and molecula

38. Experimental infection of the bat tick Carios fonsecai (Acari: Ixodidae) with the rabies virus
Introduction This study assessed the viability of the rabies virus in the argasid tick Carios fonsecai following experimental infection. Methods The mouse inoculation test (MIT), fluorescent antibody test (FAT) and polymerase chain reaction (PCR) were used. The rabies virus was administered to ticks via the intra-coelomic route, and the ticks were sacrifi

39. Characterisation of divergent flavivirus NS3 and NS5 protein sequences detected in Rhipicephalus microplus ticks from Brazil
Transcripts similar to those that encode the nonstructural (NS) proteins NS3 and NS5 from flaviviruses were found in a salivary gland (SG) complementary DNA (cDNA) library from the cattle tick Rhipicephalus microplus.Tick extracts were cultured with cells to enable the isolation of viruses capable of replicating in cultured invertebrate and vertebrate cells.

40. Turtle ectoparasites from the Pacific coastal region of Colombia
This study provides an update on the ectoparasites (ticks and leeches) associated with Rhinoclemmys annulata and provides new accounts on the ectoparasites associated with R. nasuta, R. melanosterna andKinosternon leucostomum from the Pacific coast of Colombia. The presence ofAmblyomma sabanerae on R. nasuta and R. melanosterna provided two new host records

41. Approaches towards tick and tick-borne diseases control
Ticks are obligate haematophagous ectoparasites of wild and domestic animals as well as humans, considered to be second worldwide to mosquitoes as vectors of human diseases. Tick-borne diseases are responsible worldwide for great economic losses in terms of mortality and morbidity of livestock animals. This review concerns to the different tick and tick-para

42. Molecular identification of Rickettsia parkeri infecting Amblyomma triste ticks in an area of Argentina where cases of rickettsiosis were diagnosed
Specimens of the hard tick Amblyomma triste were found infected with Rickettsia parkeri in an area of Argentina (General Lavalle, Buenos Aires Province) where cases of human illness attributed to this microorganism have been reported. Molecular detection of R. parkeri was based on polymerase chain reactions that amplify a ca. 400-bp fragment of the 23S-5S in

43. EVALUATION OF ESSENTIAL OILS LEMONGRASS, CITRONELLA AND EUCALYPTUS IN TICK CONTROL / AVALIAÇÃO DE ÓLEOS ESSENCIAIS DE CAPIM LIMÃO, CITRONELA E EUCALIPTO NO CONTROLE DO CARRAPATO
Esta pesquisa foi conduzida com o objetivo de avaliar o efeito in vitro e in vivo do óleo de capim limão (Cymbopogon flexuosus Stapf.), citronela (Cymbopogon winterianus Jowitt) e eucalipto (Corymbia citriodora) sobre o carrapato bovino (Rhipicephalus (Boophilus) microplus), sendo que cada óleo essencial corresponde a um experimento. Nas experimentações

44. A prevalent alpha-proteobacterium Paracoccus sp. in a population of the Cayenne ticks (Amblyomma cajennense) from Rio de Janeiro, Brazil
As Rocky Mountain Spotted Fever is the most common tick-borne disease in South America, the presence of Rickettsia sp. in Amblyomma ticks is a possible indication of its endemicity in certain geographic regions. In the present work, bacterial DNA sequences related to Rickettsia amblyommii genes in A. dubitatum ticks, collected in the Brazilian state of Mato

45. Influence of essential oil fractionation by vacuum distillation on acaricidal activity against the cattle tick
The aim of this work was to study the influence of essential oil fractionation on acaricidal activity against the cattle tick Rhipicephalus (Boophilus) microplus. The citronella (Cymbopogon winterianus J.) and pepper tree (Schinus molle L.) essential oils were fractionated by vacuum distillation yielding fractions that were analyzed by the GC/MS. Laboratory

46. Rickettsia parkeri: a Rickettsial pathogen transmitted by ticks in endemic areas for spotted fever rickettsiosis in southern Uruguay
At first Rickettsia conorii was implicated as the causative agent of spotted fever in Uruguay diagnosed by serological assays. Later Rickettsia parkeri was detected in human-biting Amblyomma triste ticks using molecular tests. The natural vector of R. conorii, Rhipicephalus sanguineus, has not been studied for the presence of rickettsial organisms in Uruguay

47. Prevalence of antibodies to Borrelia burgdorferi sensu stricto in humans from a Cuban village
Lyme disease has not been officially reported in Cuba. However, clinical cases have been serologically reported. Seroprevalence survey of Borrelia burgdorferi sensu stricto antibodies in humans in the country has not been conducted. OBJECTIVE: To estimate the prevalence of borrelial antibodies in inhabitants of a village with historically high level of tick

48. The first reported case of human tick paralysis in Brazil: a new induction pattern by immature stages
Tick paralysis (TP) is a rare disease with rapid progression and potential fatal evolution. Immediately after the diagnosis, removal of all ticks from the body of the patient is mandatory. The present study reports for the first time a human case of the disease in Brazil. The patient had loss of muscle strength, decreased reflexes and marked palpebral ptosis
