1. Molecular identification of Ehrlichia sp. in a beef cattle from brazilian Cerrado - case report
RESUMO Infecções por Ehrlichia em bovinos são frequentes na África, mas também foram relatadas no Brasil e na América do Norte. Este artigo relata uma infecção natural por Ehrlichia sp. associado a Babesia bigemina e Anaplasma marginale em um bezerro, no município de Campo Grande, Mato Grosso do Sul, Brasil, o qual apresentava polioencefalomalácia.

2. Biocidal potential of Eugenia pyriformis essential oil in the control of Rhipicephalus (Boophilus) microplus in the free-living cycle
RESUMO: O Brasil dispõe de um dos maiores rebanhos bovinos comerciais do mundo, sendo natural que junto a esse rebanho, coexista uma enorme quantidade de espécies parasitárias; dentre estes o carrapato Rhipicephalus (Boophilus) microplus que interfere na produtividade animal, causando prejuízos à pecuária de corte e leite. A utilização de acaricidas

3. Genetic engineering of Theileria parva lactate dehydrogenase gene: a new anti-theilerial target
ABSTRACT: Theileria parva is the causative agent of East Coast Fever (ECF), a tick borne disease, which results in major economic losses in cattle. Major problems in dealing with this illness are the high cost of drugs, development of resistance, and absence of effective vaccines. Thus, exploiting new targets for cost effective and higher therapeutic value d

4. In vivo study of a homeopathic medicine against Rhipicephalus (Boophilus) microplus in dairy cow
ABSTRACT The tick Rhipicephalus (Boophilus) microplus (Canestrini, 1887) (Acari: Ixodidae) causes large economic losses to cattle breeders and its control is hampered by problems of resistance to the main commercial synthetic acaricides and the risk of residues in animal products. Alternative controls are important for the sustainability of cattle breeding i

5. 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

6. 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.

7. 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

8. 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

9. 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

10. Avaliação in vivo da eficiência de dois imunógenos recombinantes derivados do peptídeo SBm7462 para o controle do carrapato Rhipicephalus (Boophilus) microplus (Canestrini 1887) / Evaluation efficacy in live of two recombinant immunogens derivatives of peptide SBm7462 in the control of the tick Rhipicephalus (Boophilus) microplus (Canestrini 1887)
Recombinant peptides rBmseq1 and RBmseq4 were evaluated as immunogenic for the control of ticks R. (B. ) microplus in test of stable. We used 17 bovine animals of the half-breed average degree of blood of 7/8 (H/Z), which were kept under the management routine in the Sector of isolation of bovine animals in the Department of Veterinary UFV. The animals were

11. Atividade carrapaticida do Timol sobre larvas e ninfas de Amblyomma cajennense (Acari, Ixodidae) fêmeas ingurgitadas e ovos de Rhipicephalus (Boophilus) microplus (Acari, Ixodidae)
Dentre as várias espécies de ixodídeos existentes na região neotropical, Rhipicephalus (Boophilus) microplus e Amblyomma cajennense são duas das que despertam maior interesse econômico e em saúde pública, ocasionando perdas na produção animal e atuando como vetores de agentes patogênicos. A utilização de carrapaticidas químicos sintéticos é o

12. Zero-inflated Poisson regression models for QTL mapping applied to tick-resistance in a Gyr x Holstein F2 population
Nowadays, an important and interesting alternative in the control of tick-infestation in cattle is to select resistant animals, and identify the respective quantitative trait loci (QTLs) and DNA markers, for posterior use in breeding programs. The number of ticks/animal is characterized as a discrete-counting trait, which could potentially follow Poisson dis
