ANATOMY AND HISTOLOGY OF THE FEMALE REPRODUCTIVE SYSTEM OF Boophilus microplus (ACARI: IXODIDAE)
Provedor de dados: 101
Autores: 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...

A MULTIVARIATE ANALYSIS OF Boophilus microplus (ACARI: IXODIDAE): NON-PARASITIC PHASE
Provedor de dados: 101
Autores: 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...

Autores: 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....

Abstract: The tick Rhipicephalus microplus poses a serious threat to the cattle industry, resulting in economic losses aggravated by tick resistance to chemical acaricides. Strains of Metarhizium spp., a well-known group of entomopathogenic fungi, can contribute to managing this ectoparasite. We explored two novel granular, microsclerotia- or blastospores-based formulations of Metarhizium robertsii for R. microplus control under semi-field conditions. Fungal persistence in soil was also observed for 336 days. The experiment used pots of Urochloa decumbens cv. Basilisk grass, treated with 0.25 or 0.5 mg of granular formulation/cm2 (25 or 50 kg/ha) applied to the soil surface prior to transferring engorged tick females onto the treated soil. The fungal...

Rhipicephalus (Boophilus) microplus is responsible for reducing animal welfare, causing a drop in productive performance and transmitting hemoparasites. The main strategy of tick control is application of synthetic acaricides. However, parasite resistance to these compounds is a major concern. Therefore, the acaricidal and repellent in vitro effect of the Ocotea elegans essential oil on larvae and adult females of R. (B.) microplus were evaluated. The larval packet test (LPT), larval repellency test (RT) and adult immersion test (AIT) were performed. The essential oil was analyzed by gas chromatography (GC/FID) and the structure of the oil?s major constituent (92.2% sesquirosefuran) was elucidated by nuclear magnetic resonance. In the AIT, efficacy higher...

Autores: MATIAS, J.; GARCIA, M. V.; CUNHA, R. C.; AGUIRRE, A. de A. R.; BARROS, J. C.; CSORDAS, B. G.; ANDREOTTI, R.
Rickettsia infection of each tick was evaluated by the hemolymph test and polymerase chain reaction (PCR) targeting gltA and ompA genes. All hemolymph tests were negative and PCR of one A. dubitatum detected both Rickettsia genes. Sequence of ompA exhibited a 99% identity with Rickettsia parkeri and R. africae and a 98% identity with R. sibirica. Rickettsia of the spotted fever group in A. dubitatum is described for the first time in an urban area within the municipality of Campo Grande in the state of Mato Grosso do Sul (MS), Brazil. This finding reinforces the importance of more detailed studies to determine the role of A. dubitatum in the transmission of spotted fever agents.

ABSTRACT - This paper reports the sequence analysis of Bm86 Campo Grande strain comparing it with Bm86 and Bm95 antigens from the preparations TickGardPLUS and GavacTM, respectively. The PCR product was cloned into pMOSBlue and sequenced. The secondary structure prediction tool PSIPRED was used to calculate alpha helices and beta strand contents of the predicted polypeptide. The hydrophobicity profile was calculated using the algorithms from the Hopp and Woods method, in addition to identification of potential MHC class-I binding regions in the antigens. Pair-wise alignment revealed that the similarity between Bm86 Campo Grande strain and Bm86 is 0.2% higher than that between Bm86 Campo Grande strain and Bm95 antigens. The identities were 96.5% and 96.3%...

The cattle tick Rhipicephalus microplus causes significant economic losses in agribusiness. Control of this tick is achieved mainly through the application of chemical acaricides, often resulting in contamination of animal food products and of the environment. Another major concern associated with acaricide use is the increasing reports of resistance of this tick vector against the active ingredients of many commercial products. An alternative control method is vaccination. However, the commercially available vaccine based on a protein homologous to Bm86 exhibits variations in efficacy relative to the different geographical locations. This study aimed to identify antigenic determinants of the sequences of proteins homologous to Bm86. Phylogenetic analyses...

The Rhipicephalus (Boophilus) microplus complex currently consists of five taxa, namely R. australis, R. annulatus, R. (B.) microplus clade A sensu, R. microplus clade B sensu, and R. (B.) microplus clade C sensu. Mitochondrial DNA-based methods help Taxonomists when they are facing the morpho-taxonomic problem of distinguishing members of the R. (B.) microplus complex. The purpose of this study was to perform molecular characterization of ticks in all five regions of Brazil and infer their phylogenetic relationships. Molecular analysis characterized 10 haplotypes of the COX-1 gene. Molecular network analysis revealed that haplotype H-2 was the most dispersed of the studied populations (n = 11). Haplotype H-3 (n = 2) had the greatest genetic...

In vitro efficacy of Metarhizium anisopliae sensu lato against unfed Amblyomma parvum (Acari: Ixodidae).
Provedor de dados: 119
Autores: GARCIA, M. V.; RODRIQUES, V. da S.; MONTEIRO, A. C.; SIMI, L. D.; HIGA, L. de O. S.; MARTINS, M. M.; PRETTE, N.; MOCHI, D. A.; ANDREOTTI, R.; JUAN SZABÓ, M. P.
Amblyomma parvum Aragão (Acari: Ixodidae) is a tick species found with wide distribution in the Neotropical region. Even though it is a wildlife-related tick, it is also a frequent parasite of domestic animals, is aggressive to human beings and may harbor pathogenic microorganisms. Therefore, it is a target species for control on domestic animals, particularly those at the rural?wildlife interface. Herein, the efficacy of two isolates (E9 and IBCB 425) of an entomopathogenic fungus, Metarhizium anisopliae sensu lato, already evaluated for ticks that parasitize domestic animals, was tested against unfed A. parvum adults. Both isolates displayed high acaricidal efficacy after immersion in fungal conidial suspensions for 5 min. Isolate E9 killed all ticks by...

O desenvolvimento de uma resposta imune efetiva depende da ação orquestrada de diversos subtipos celulares que atuam tanto na resposta imune inata quanto adaptativa. Desse modo, é de grande importância a realização de estudos sobre o comportamento dessas células em diferentes raças de bovinos com propósito de desenvolver soluções para animais menos resistentes a agentes infecciosos. Para o isolamento destas células, é preciso estabelecer protocolos padronizados de coleta de buffy coat e células mononucleares de sangue periférico (PBMCs), os quais possam ser utilizados para diferentes raças de bovinos buscando reduzir possíveis interferentes. Durante a condução dos experimentos, foram feitas otimizações de protocolo como a substituição de reagentes e adição...

Autores: OBREGÓN, D.; CORONA-GONZÁLEZ, B.; DÍAZ-SÁNCHEZ, A. A.; ARMAS, Y.; ROQUE, E.; OLIVEIRA, M. C. de S.; CABEZAS-CRUZ, A.
Water buffaloes can be infected by tick-borne pathogens (TBPs) in endemic areas where cattle and buffalo coexist. Among TBPs affecting buffaloes is the Apicomplexan hemoparasites Babesia bovis and B. bigemina, transmitted by Rhipicephalus microplus ticks. However, little empirical evidence exists on whether buffalo can support TBPs? infection and transmission. A cohort study was designed to measure the infestation levels of R. microplus in buffaloes as well as the ability of buffalo-fed ticks to transmit B. bovis and B. bigemina to their offspring. Tick infestation of different life stages was quantified in cattle and buffalo kept in field conditions in western Cuba. Engorged adult female ticks were allowed to lay eggs in controlled conditions of humidity...

Autores: HIGA, L. de O. S.; GARCIA, M. V.; BARROS, J. C.; KOLLER, W. W.; ANDREOTTI, R.
The Rhipicephalus (Boophilus) microplus tick is responsible for considerable economic losses in Brazil, causing leather damage, weight loss and reduced milk production in cattle and results in the transmission of pathogens. Currently, the main method for controlling this tick is using acaricides, but their indiscriminate use is one of the major causes of resistance dissemination. In this study, the adult immersion test (AIT) was used to evaluate resistance in ticks from 28 properties located in five different states (Mato Grosso do Sul, Mato Grosso, Ceará, São Paulo, e Minas Gerais) and the Distrito Federal (DF) of Brazil. The resistance was found in 47.64% of the repetitions demonstrating an efficacy of less than 90% in various locations throughout the...

Autores: GARCIA-FERNANDEZ,CASIMIRO; GARCIA,SONIA M. LAUER DE; GARCIA,ROSANE NUNES.
A topographical and histological study of the male genital accessory gland complex of Boophilus microplus was undertaken. Ten lobes were found, the most prominent of which is the single dorso-median lobe, subdivided into antero-dorsal and postero-dorsal lobes. The other lobes are: a pair of postero-ventral lobes, a pair of lateral lobes (subdivided into dorso-lateral and postero-lateral lobes), a pair of antero-ventral lobes, a single medio-ventral lobe and a pair of latero-ventral lobes. These lobes were observed to present individual topographical and histological characteristics, with independent openings, hence the conclusion is that they form a gland complex. The secretory nature of the dorso-median lobe duct was also analysed.

The structural analysis of oviducts in Boophilus microplus (Canestrini, 1887) in different stages of ingurgitation has indicated that they are constituted primarily of an internal cylinder and an external cylinder with different cell types being found between them. Copulated females in active ingurgitation process show typical variations along the internal cylinder, and three regions can be defined: anterior, ring-like and transitional. Based on such regionalization, hypotheses were raised about where and how fertilization takes place, a process yet to be clarified for the acari.

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...

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...

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...

ABSTRACT: Ticks are arthropods that are highly competent in transmitting pathogens to animals and humans. Among these, the genus Amblyomma is the most representative within the Neotropics. Amblyomma longirostre ticks are naturally distributed in countries of South, Central and North America. Their immature stages preferentially parasitize birds (Passeriformes), while adult stages are usually found on rodents. Therefore, reports of this tick species on wild hosts is epidemiologically relevant, especially because of these ticks' potential for transmitting pathogens to other wild and domestic animals, and also to humans. Thus, the aim of this study was to report infestation by Amblyomma longirostre on Cyanocompsa brissonii in southern Brazil.

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...

New histochemical and morphological findings in the female genital tract of Boophilus microplus (Acari, Ixodidae): an attempt toward the elucidation of fertilization in ticks
Provedor de dados: 76
Autores: García-Fernández,Casimiro; Garcia,Sonia M. Lauer; Garcia,Rosane Nunes; Valente,Vera L. da Silva.
At present not only is the site of fertilization in ticks still unknown but it is also unclear as to how this mystery can be solved. Signs of fertilization can be observed throughout the female genital tract and these can be clues for the elucidation of the unsolved questions relating to ticks fertilization. In Boophilus microplus (Canestrini, 1887) the most important signs are the following: the final eversion of the acrosomal canal in females ready for oviposition; the presence of small tubules, resembling the subplasmalemal process of the spermatozoon between the oviduct cells; budding nuclei throughout the female genital tract; and the two Feulgen and DAPI positive areas in the oocyte at vitelogenesis. These morphological characteristics suggest that...

Autores: 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...

Autores: ANDREOTTI, R.; GARCIA, M. V.; BARROS, J. C.; KOLLER, W. W.; RODRIGUES, V. da S.
Os carrapatos são artrópodes hematófagos que parasitam muitas espécies de hospedeiros, desde mamíferos até anfíbios, e podem ser encontrados em vários ambientes nas diversas regiões do planeta. O tema ?Carrapatos no Brasil? tem importância, tanto na saúde animal quanto ao aspecto econômico. Os prejuízos, apenas no que tange a cadeia produtiva de bovinos no país, são estimados em 3,2 bilhões de dólares ao ano. Com respeito à saúde pública a bactéria Rickettsia rickettsii, agente da febre maculosa brasileira (FMB), tem os carrapatos por vetores. Contudo, os prejuízos relativos à manutenção da saúde pública não foram ainda estimados, e são incalculáveis quando se trata de perdas de vidas humanas. O Museu do Carrapato tem por objetivo apresentar, de forma...

Autores: OLIVEIRA, G. P. de; MATSUMOTO, T.; OLIVEIRA, M. C. de S.
0 controle efetivo da dermatobiose pode ser feito por meio de dois tipos de tratamentos: estratégico e tático. Como foi visto, dois fatores são considerados importantes na exacerbação da D. hominis \te seus veiculadores, a temperatura e a umidade. Em nossa região, a temperatura inicia o seu limiar favorável a biologia dos insetos logo após o inverno, quando começa a se elevar. Na mesma época, reiniciam-se as precipitações pluviais, condicionando a atmosfera com alto teor de umidade. É fim de setembro e inicio da primavera, período em que acontece a eclosão dos insetos. Nessa época, como os dados experimentalmente obtidos indicam, acontecem as maiores infestações de berne (setembro e outubro). Devido a tal condição, sugere-se o tratamento estratégico de...

In Brazil as in the rest of the world, sectors of production and commercialization of animal originated foods, are changing to attend the two highst marcket demands: competitivity and quality. These exigencies are specially related to healthy foods. So the use of products that leave residues in meat and/or milk is going to be more restritive in an animal production system pointed to sustentability with lower environmental risks. Factors such as: pasture seasonal fluctuations, nutricional defficiencies, management conditions, high parasites incidence and general diseases contribuited to reduction of production and productivity of bovines. Verminosis is the name to the infections caused by endoparasites. In the tropics, these deseases usually show low...

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...

Babesia microti is a tick-transmitted zoonotic hemoprotozoan parasite. In the present study, we investigated B. microti infection in questing ticks in Mongolia. A total of 219 questing ticks were collected from three different Mongolian provinces (Bayan-Olgii, Khovsgol, and Selenge). Of these, 63 from Selenge were identified as Ixodes persulcatus, while the remaining 156 (from all three provinces) were identified as Dermacentor nuttalli. When the tick DNA samples were screened using a B. microti-specific nested PCR, 19 (30.2%) of the 63 I. persulcatus ticks were found to be B. microti-positive. The parasite was not detected in D. nuttalli. Subsequently, the 18S rRNA, cox1, and tufA sequences of B. microti were amplified, sequenced, and subjected to...

Provedor de dados: 103
Autores: 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...

Parasite loads and altitudinal distribution of Liolaemus lizards in the central Chilean Andes
Provedor de dados: 97
Autores: CAROTHERS,JOHN H.; JAKSIC,FABIÁN M.
This study compared the distributions of ten species of Liolaemus lizards in the central Chilean Andes to the distributions of four types of parasites: malaria-causing Plasmodium, gut nematodes, ticks, and mites. We wanted to see if parasite numbers might be a factor in determining distributional limits of the lizards. We found that there was no evidence of malarial infestation of the lizards, that ticks were almost absent, that more often than not mite numbers decreased at the distributional limits of the lizards, and that gut nematodes confined to the herbivorous lizards in our sample may well be beneficial rather than detrimental. Rather than parasitism, other biotic interactions (e.g., predation or competition) are more likely candidates as factors...
