Multivariate statistical methods are relatively new tools for data analysis. They have a lot of applications in biological researches: nevertheless, for several reasons, they have not been widely employed in this subject yet. Recently, present authors published a paper applying multivariate statistics on non-parasitic phase of Anocentor nitens. In the present article Boophilus microplus has received a very similar statistic treatment. In this paper, the influence of different incubation conditions was studied in groups of 12-15 individuals in each of the 24 combinations of six temperatures 24, 27, 30, 32, 34 and 36ºC and four relative humidity values, 100, 80, 75.5 and 70% over the cycle variables of B. microplus. According to the results, the best... |

Multivariate statistical methods are useful tools complementary to classic univariate methods. In biology, they are used in several scenarios where data structure, classification and grouping are necessary. Nevertheless, it seems they have not been employed in the study of non-parasitic phase of ticks or any other arthropod. In this paper, the influence of different incubation conditions was studied in groups of 12-15 individuals in each of the 24 combinations of six temperatures 24, 26, 28, 30, 32, and 34ºC and four relative humidities 100, 80, 75.5 and 70% over the cycle variables of Anocentor nitens looking for establishing the most suitable environmental conditions to increase or decrease ticks performance and to apply these knowledges to zoogeography.... |

Abstract Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the... |

Eight wild fowls kept in captivity at a Brazilian Zoo were examined from july 1994 to October 2000. One hundred twenty-three Ixodidae specimens were collected and sent to the Ixodides Laboratory at the Instituto Oswaldo Cruz, Rio de Janeiro, Brazil. They were examined by stereomicroscopy and were identified as Amblyomma longirostre (53), A. pacae (50), A. cajennense (14), and A. parvum (6). |

Ehrlichiosis is a worldwide distributed disease caused by different bacteria of the Ehrlichia genus that are transmitted by arthropod vectors. Its occurrence in dogs is considered endemic in several regions of Brazil. Regarding cats, however, few studies have been done and, consequently, there is not enough data available. In order to detect Ehrlichia spp. in cats from the central-western region of Brazil, blood and serum samples were collected from a regional population of 212 individuals originated from the cities of Cuiabá and Várzea Grande. These animals were tested by the Immunofluorescence Assay (IFA) and the Polymerase Chain Reaction (PCR) designed to amplify a 409 bp fragment of the dsb gene. The results obtained show that 88 (41.5%) cats were... |

We studied the ecology of ticks found in different species of a taxocenosis of snakes from the Serra do Mendanha, an area of Atlantic Rainforest located in the state of Rio de Janeiro, southeastern Brazil. Snakes were sampled monthly in the field during a period of 48 months. The specific identity of the hosts and their parasites, the number of parasites, and and snout-vent length and body mass of each host were recorded. A total of 25% of the species of snakes in the area were parasitized by ticks (larvae, nymphs and adult females) Amblyomma rotundatum Koch, 1844 was the predominant parasite species. The infestation parameters varied among the species of snakes sampled, with the highest prevalence of A. rotundatum being observed in the viperid Bothrops... |

Nos últimos anos, a Embrapa Gado de Corte tem recebido inúmeras indagações por carta, telefone, em palestras etc. sobre a utilização do alho, em especial, no controle da mosca-dos- chifres (Haematobia irritans irritans) em bovinos. O principal objetivo do experimento foi verificar a eficácia do alho em pó, adicionado ao sal mineral, no controle de mosca-dos-chifres, carrapatos (Boophilus microplus) e helmintos de bovinos. Foram utilizados 42 novilhos cruzados, distribuídos em dois grupos de 21 animais, levando-se em consideração a raça, o peso, ovos por grama de fezes (OPH), numero de moscas, idade e o numero de carrapatos. Durante todo o período experimental, os grupos ficaram em piquetes separados com pastagens de Brachiaria decumbens. Um grupo de... |

Background: Acaricide failure has been on the rise in the western and central cattle corridor of Uganda. In this study, we identified the tick species associated with acaricide failure and determined their susceptibility to various acaricide molecules used for tick control in Uganda. Methods: In this cross sectional study, tick samples were collected and identified to species level from 54 purposively selected farms (from 17 districts) that mostly had a history of acaricide failure. Larval packet test was used to screen 31 tick populations from 30 farms for susceptibility at discriminating dose (DD) and 2 x DD of five panels of commercial acaricide molecules belonging to the following classes; amidine, synthetic pyrethroid (SP), organophosphate (OP) and... |

ABSTRACT: The aim of this study was to investigate exposure of Baixadeiro horses to Rickettsia spp. and to ticks infected by Rickettsia in the Baixada Maranhense (lowlands) micro-region, state of Maranhão. A total of 258 horses were tested for Rickettsia rickettsii, Rickettsia amblyommatis and Rickettsia bellii using the immunofluorescence assay (IFA). Overall, 58.91% (152/258) of the horses were seroreactive for at least one Rickettsia species, and 85.27% of the horses were infested with one or more species of tick, which were identified as Dermacentor nitens (93.63%), Amblyomma cajennense sensu stricto (4.55%) and Rhipicephalus (Boophilus) microplus (1.82%). These ticks were subjected to DNA extraction and were tested using the polymerase chain reaction... |

The aim of this study was to investigate the presence of DNA of Borrelia burgdorferi sensu lato (s.l.) in ticks that feed on horses used for animal traction in rural Jataizinho, Parana, Brazil. Between February and June 2008, a total of 224 ticks was collected of which 75% were identified as Dermacentor nitens and 25% as Amblyomma cajenense. To amplify B. burgdorferi s.l. DNA, the intergenic space region (ISR) between the 5S (rrf) 23S (rrl) rRNA genes was used as targets for nested-PCR. Two ticks of the D. nitens species were positive for B. burgdorferi s.l. Both species showed a fragment of 184 bp, but the sequencing revealed 99.9% homology with the B. burgdorferi sensu stricto (s.s.) strain B31. These results showed, for the first time, the presence of... |

Ticks are bloodsucking arachnids that parasitize domestic animals and a diversity of wild animals in terrestrial environments of the planet. This study reports the occurrence of hard ticks on wild animals from the countryside of São Paulo state, Brazil, which were forwarded to the Sorocaba zoo. During the years of 2014, 2015 and 2016, using taxonomic keys, ticks were collected from naturally infested wild animals that were sent to the zoo, and were taxonomically identified in the laboratory. In total, 675 tick specimens were identified into 14 different tick species, collected from one reptile specimen, four birds and 31 mammal specimens, totaling 17 different species of wild animals. This work reports for the first time Amblyomma sculptum adults... |
