1. 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

2. 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

3. 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.

4. 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

5. 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

6. 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

7. Detecção do vírus da diarreia viral bovina em carrapatos Rhipicephalus (Boophilus) microplus alimentados em bovino persistentemente infectado= Detection of bovine viral diarrhea virus in Rhipicephalus (Boophilus) microplus ticks fed on persistently infected cattle / Detection of bovine viral diarrhea virus in Rhipicephalus (Boophilus) microplus ticks fed on persistently infected cattle
Background: Bovine viral diarrhea virus (BVDV) is one of the main agents that cause economical losses in cattle worldwide. Congenitally infected calves that are born persistently infected (PI) to BVDV are the main sources of infection to susceptible cattle. Direct contact is the most important form of transmission, but indirect contact can also spread BVDV,

9. PCR-based detection of babesia bovis and babesia bigemina in their natural host Boophilus microplus and cattle.
PCR and nested-PCR methods were used to assess the frequency of Babesia bovis and Babesia bigemina infection in Boophilus microplus engorged females and eggs and in cattle reared in an area with endemic babesiosis. Blood and the engorged female ticks were from 27 naturally infested calves and 25 crossbred cows. The frequency of both Babesia species was simil

Background: Ticks are distributed worldwide, with impacts on human and animal health. The cattle tick Rhipicephalus (Boophilus) microplus is the main parasite that affects livestock in tropical and subtropical regions of the world, causing large economical losses. Tick control methods are based on the application of chemical acaricides, which has resulted in

12. Sensibilidade do carrapato Boophilus microplus a solventes.
A study was conducted to investigate the sensitivity of Boophilus microplus cattle ticks to different solvents. Larvae and engorged females of B. microplus were subjected to 7 solvents in 5 different concentrations in the presence and absence of olive oil. The utilization of olive oil did not produce different statistical results in the impregnated paper lar
