A MULTIVARIATE ANALYSIS OF Boophilus microplus (ACARI: IXODIDAE): NON-PARASITIC PHASE Rev Salud Anim.
de la Vega,R; Díaz,G; da Fonseca,A.H.
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...

A MULTIVATIATE ANALYSIS OF Anocentor nitens (IXODOIDEA: IXODIDAE): NON-PARASITIC PHASE/[title] [title language=es]ANÁLISIS MULTIVARIADO DE Anocentor nitens (IXODOIDEA: IXODIDAE): FASE NO PARASITARIA Rev Salud Anim.
de la Vega,R; Díaz,G.
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....

An Alternative and Rapid Method for the Extraction of Nucleic Acids from Ixodid Ticks by Potassium Acetate Procedure BABT
Rodríguez,Islay; Fraga,Jorge; Noda,Angel Alberto; Mayet,Milagro; Duarte,Yanisia; Echevarria,Eduardo; Fernández,Carmen.
Four variants of the potassium acetate procedure for DNA extraction from ixodid ticks at different stage of their life cycles were evaluated and compared with phenol-chloroform and ammonium hydroxide methods. The most rapid and most efficient variant was validated in the DNA extraction procedure from the engorged ticks collected from bovine, canine as well as from house ticks for the screening of Borrelia burgdorferi sensu lato, Anaplasma spp. and Babesia spp. The ammonium hydroxide procedure was used for non-engorged ticks. All the variants were efficient and allowed obtaining PCR-quality material according to the specific amplification of 16S rRNA gene fragment of the original tick. DNA extracted from the ticks under the study was tested by multiplex PCR...

ANATOMY AND HISTOLOGY OF THE FEMALE REPRODUCTIVE SYSTEM OF Boophilus microplus (ACARI: IXODIDAE) Rev Salud Anim.
de la Vega,R; Díaz,G; Galán,M; Fernández,C.
The knowledge of the anatomy and histology of the female genital system in ticks is very important as a basic tool in all species in relation to morphological sciences and evolution, physiological events like ovulation, sexual behavior, maturation and mating, and also to research the interrelation tick-hemoparasite. The anatomy and histology of the female genital system in Boophilus microplus are scarcely studied. In the present paper, the female genital system of this tick has been considered as a whole and morphological and functional interrelations between different structures and also some other related items has been presented. Unfed and partially engorged females were employed in the study. The quality and resolution of images are remarkable because...

Brazilian borreliosis with special emphasis on humans and horses BJM
Basile,Roberta Carvalho; Yoshinari,Natalino Hajime; Mantovani,Elenice; Bonoldi,Virgínia Nazário; Macoris,Delphim da Graça; Queiroz-Neto,Antonio de.
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...

Controle do carrapato por meio de vacina - situação atual e perspectivas. Infoteca-e
ANDREOTTI, R.; GOMES, A.; MALAVAZI-PIZA, K. C.; TANAKA, A. S..
Boophilus microplus causa grandes prejuízos econômicos à exploração pecuária no Brasil em função da espoliação dos bovinos, pela transmissão de patógenos, e do alto cursto operacional das técnicas atuais de controle. O combate sistemático ao carrapato do boi faz-se necessário, principalmente nos rebanhos de produção estabelecidos com base em raças européias ou mestiças. O uso de acaricidas ven sendo a medida de conrole profilático e terapêutico mais comum contra esses estoparasitos. Os principais problemas relacionados com essa prática dizem respeito ao desenvolvimento de linhagens resistentes de carrapatos frente a diversas geraçoes de acaricidas, ao aparecimento de resíduos químicos nos produtos de origem animal e à poluição ambiental proveniente do uso...

Braga,Ísis Assis; Santos,Luana Gabriela Ferreira dos; Ramos,Dirceu Guilherme de Souza; Melo,Andréia Lima Tomé; Mestre,Gustavo Leandro da Cruz; Aguiar,Daniel Moura de.
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...

Pontes,Jorge A. L.; Gazêta,Gilberto S.; Vrcibradic,Davor; Rocha,Carlos F. D..
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...

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...

Gonçalves,Daniela Dib; Carreira,Teresa; Nunes,Mónica; Benitez,Aline; Lopes-Mori,Fabiana Maria Ruiz; Vidotto,Odilon; Freitas,Julio Cesar de; Vieira,Maria Luísa.
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...

Garcia,Marcos Valerio; Monteiro,Antonio Carlos; Szabo,Matias Juan Pablo; Prette,Nancy; Bechara,Gervásio Henrique.
The present work aimed to verify the penetration pattern of the Metarhizium anisopliae fungus into Rhipicephalus sanguineus tick eggs, as well as the lesions occurred inside the egg. The fungus adherence and penetration were studied by scanning electron microscopy and the action of fungus in the internal tissues was evaluated through conventional histological sessions. For the observation of these events, experimental infections were performed in 11 groups of R. sanguineus eggs containing 25 mg each. The eggs were bathed during 3 minutes under manual shaking in a 10(8) conidia/mL suspension. The bath was performed only in the suspension vehicle for the control groups. The eggs were processed for histopathological analysis and scanning electron microscopy...
