Abstract Ticks represent a large group of pathogen vectors that blood feed on a diversity of hosts. In the Americas, the Ixodidae ticks Amblyomma cajennense are responsible for severe impact on livestock and public health. In the present work, we present the isolation and molecular identification of a group of culturable bacteria associated with A. cajennense eggs from females sampled in distinct geographical sites in southeastern Brazil. Additional comparative analysis of the culturable bacteria from Anocentor nitens, Rhipicephalus sanguineus and Ixodes scapularis tick eggs were also performed. 16S rRNA gene sequence analyses identified 17 different bacterial types identified as Serratia marcescens, Stenotrophomonas maltophilia, Pseudomonas fluorescens,...

The first reported case of human tick paralysis in Brazil: a new induction pattern by immature stages
Provedor de dados: 80
Autores: Almeida,RAMB; Ferreira,MA; Barraviera,B; Haddad Jr,V.
Tick paralysis (TP) is a rare disease with rapid progression and potential fatal evolution. Immediately after the diagnosis, removal of all ticks from the body of the patient is mandatory. The present study reports for the first time a human case of the disease in Brazil. The patient had loss of muscle strength, decreased reflexes and marked palpebral ptosis. Six hours after removal of the last tick, the ptosis improved and on the following day, the patient had near total regression of the symptoms. This report emphasizes the possible presence of similar cases that should be promptly diagnosed and quickly treated. A new induction pattern for TP in humans associated with immature stages of ticks is also presented.

Rodents Of The Subfamily Caviinae (Hystricognathi, Caviidae) As Hosts For Hard Ticks (Acari: Ixodidae)
Provedor de dados: 81
Autores: Guglielmone,Alberto A; Nava,Santiago.
There are only 33 records of rodents of the subfamily Caviinae Fischer de Waldheim, 1817 (Hystricognathi: Caviidae) infested by hard ticks in South America, where the subfamily is established. Caviinae is formed by three genera: Cavia Pallas, 1766, Galea Meyen, 1833 and Microcavia Gervais and Ameghino, 1880. Records of Amblyomma pictum Neumann, 1906, A. dissimile Koch, 1844 and A. pseudoparvum Guglielmone, Keirans and Mangold, 1990 are considered doubtful. Bona fide records are all for localities south of the Amazonian basin in Argentina, Bolivia, Uruguay and Brazil. Thirteen records are for A. tigrinum Koch, 1844, four for A. triste Koch, 1844, three for A. parvum Aragão, 1908 (larvae and nymphs of these three species), one for A. cajennense (Fabricius,...

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...

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...

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....

Estudo comparativo do aspecto da hemolinfa de algumas espécies de carrapatos (Acari, Ixodidae): descrição da variação hemocitária de adultos de Amblyomma cajennense (Fabricius) Koch
Provedor de dados: 104
Autores: Carneiro,Maria Elisa; Daemon,Erik.
The hemocyte composition of adults of Amblyomma cajennense (Fabricius, 1787) Koch, 1844 adults consisted of three basic cellular types: prahemocyte I (PR I), plasmatocyte (PL) and spherulocyte (ES II). Among the ixodids observed (A. cajennense; A. dissimile Koch, 1844; Rhipicephalus sanguineus Latreille, 1806; Anocentor nitens (Neumann, 1897) Schulze, 1937; Boophilus microplus Canestrini, 1887 and Haemaphysalis sp.) only A. cajennense was different in the adult hemolymph colour. It changed from amber to deep blue as the ixodid age advanced. This fact could be associated with the presence of hemocyanin in the hemolymph and points out the need to develop further investigations about the Ixodidae hemolymph pratein composition as well as the function of all...

Autores: Fernandes,F.F.
In order to monitor the susceptibility of Boophilus microplus to acaricides and improve control measures, the effects of cypermethrin, deltamethrin and permethrin on larvae obtained in the city of Goiânia in the Brazilian state of Goiás were studied. Although these pyrethroids are already sold as acaricides, their cost-benefit efficiency has been questioned. Fasting 14-21 day-old larvae were immersed in solutions of the acaricides under test, maintained at 27±1° C, and relative humidity over 80%, and observed under the stereoscope within an apparatus originally designed for studying the non-parasitic phase of the tick life cycle. The observed toxicological effects were: excitability, repetitive motion, decreased motor ability, detachment, paralysis,...

Provedor de dados: 57
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.

During a survey for ectoparasites on birds in a small reserve of the Brazilian cerrado (savannah) a male adult Rhipicephalus sanguineus tick was found attached to the eyelid of the bird Coereba flaveola. Both tick and bird are presently common in Brazil, however, to best of our knowledge, the association of this tick species with this bird species has not been reported before. This observation may be an accidental finding but might also be an unknown route for the dissemination of the tick. The species R. sanguineus was introduced in the country with the colonization and should be considered a research target for the surveillance of tick-borne diseases.

O carrapato Boophilus microplus é a espécie de maior distribuição geográfica e importância econômica para os países produtores de bovinos em áreas tropicais e sub-tropicais do planeta. No Brasil, a Região Nordeste apresenta algumas áreas mais favoráveis para as infestações do gado. O controle químico ainda é a forma mais eficaz de combate deste ectoparasita, mas o manejo inadequado dos acaricidas tem contribuído com o aparecimento de resistência de populações aos produtos disponíveis no mercado. O município de Ilhéus, na Região Cacaueira da Bahia, vem incrementando sua atividade pecuária em substituição à lavoura cacaueira devastada. Foram realizados 30 testes de imersão in vitro (biocarrapaticidogramas) com fêmeas ingurgitadas de B. microplus colhidas em...

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.
