“…This tick is the one that is most prevalent in dogs in these areas (SZABÓ et al, 2001(SZABÓ et al, , 2010 and infestations usually occur more intensely (SZABÓ et al, 2001;VIEIRA et al, 2013). In the northern region of Paraná, a similar distribution of ticks was found among dogs in a hospital population, which also originated from urban areas (OYAFUSO et al, 2002). However, previous studies have verified ticks of this species in dogs from the rural area of the northern region of the state VIEIRA et al, 2013).…”

“…In contrast, dogs in rural or suburban areas can are exposed to infestation by several species of ticks that were originally native to wild mammals of the Brazilian fauna, belonging to the genus Amblyomma spp., and also to infestation by R. (Boophilus) microplus (LABRUNA & PEREIRA, 2001;. In Paraná, studies on identification of tick species in dogs have so far been limited to the northern region of the state, where ticks of the species R. sanguineus s. l. OYAFUSO et al, 2002;VIEIRA et al, 2013) (OYAFUSO et al, 2002;VIEIRA et al, 2013) have been reported.…”

“…Knowledge of the species of Ixodidae fauna in a region is important for determining the possible diseases transmitted by these vectors and their risk of occurrence (OYAFUSO et al, 2002). The objectives of the present study were to identify tick species that parasitize dogs in urban and rural areas of three mesoregions: Metropolitana de Curitiba (MC), Centro Oriental (COP) and Centro Sul Paranaense (CSP), and to determine the rate of occurrence of each species, according to the mesoregion.…”

The present study aimed to contribute towards identification and registration of tick species that parasitize dogs in rural and urban areas of three mesoregions of Paraná, southern Brazil, and to estimate the rate of occurrence of each species. Fifty-six dogs with ticks living in three mesoregions: Metropolitana de Curitiba (MC), Centro Oriental (COP) and Centro Sul Paranaense (CSP), were used in the study. From these 56 dogs, 253 ticks were collected and were identified and morphologically characterized according to the species. Among all the ticks, 69.6% were identified as belonging to the species Rhipicephalus sanguineus sensu lato (s.

“…In tropical regions, a vast variety of ticks infest dogs living either in urban areas, where Rhipicephalus sanguineus is the predominant species (SZABÓ et al, 2001;OYAFUSO et al, 2002), or in peri-urban and rural areas, where dogs are frequently infested with Amblyomma species, including Amblyomma cajennense (LABRUNA et al, 2000). This tick is popularly known as "star tick" or "rodoleiro" tick.…”

The present study aimed to evaluate the occurrence of immune resistance in dogs successively infested with Amblyomma cajennense nymphs. Five animals were submitted to four consecutive infestations with A. cajennense nymphs, at fourteen-day intervals. For each infestation, 50 nymphs were used per animal and data on the parasitic and non-parasitic periods were recorded. The average recovering rate of engorged nymphs in the successive infestations were 52.0, 29.2, 9.6 and 12.8%, respectively, with a significant reduction (p < 0.05) of this parameter from the second infestation onwards. The modal drop-off day of engorged nymphs was Day 4 of parasitism in all infestations. The average mortality rates of nymphs seen on the first, second, third and fourth infestations were 3.6, 3.2, 2.0 and 2.8%, respectively, with no significant differences among them (p < 0.05). In addition, no significant differences were seen among the ecdysis rates for specimens recovered from successive parasitic challenges. The study results suggest that the acquired resistance of infested dogs had a negative effect on recovery rate of A. cajennense nymphs; however, it did not affect the other biological parameters evaluated.Keywords: Immune resistance, Amblyomma cajennense, Ixodidae, dogs. ResumoO presente trabalho teve por objetivo avaliar a ocorrência de resistência imune em cães, frente a infestações sucessivas por ninfas de Amblyomma cajennense. Para tanto, cinco animais foram submetidos a quatro infestações consecutivas por ninfas de A. cajennense em intervalos de quatorze dias. Foram aplicadas 50 ninfas em cada animal por infestação e os dados referentes aos períodos parasitários e não parasitários, foram registrados. As taxas médias de recuperação de ninfas ingurgitadas, verificadas nas sucessivas infestações foram de 52,0, 29,2, 9,6 e 12,8%, sendo observada uma redução significativa (p < 0,05) nesse parâmetro a partir da segunda infestação. O dia modal de queda das ninfas ingurgitadas em todas as infestações foi o 4º dia de parasitimo. As taxas médias de mortalidade de ninfas observadas no primeiro, segundo, terceiro e quarto desafio parasitário foram de, respectivamente, 3,6, 3,2, 2,0 e 2,8%, não havendo diferença significativa entre elas (p < 0,05). Não observou-se diferença significativa (p < 0,05) entre as taxas de ecdise reportadas para os exemplares recuperados nos sucessivos desafios parasitários. Esses resultados sugerem que a resistência adquirida nos cães parasitados afetou negativamente a taxa de recuperação das ninfas de A. cajennense inoculadas nesses animais, contudo não apresentou nenhum efeito sobre os demais parâmetros biológicos avaliados.Palavras-chave: Resistência imune, Amblyomma cajennense, Ixodidae, cão.

As teleóginas, que são fêmeas ingurgitadas, repletas de sangue, depois de fecundadas, desprendem-se do hospedeiro, caindo no solo onde estão prontas para realizar a ovipostura única em torno de 5.000 a 10.000 ovos.…”

The objective of this research was to elaborate and validate an Educational Technology about Rocky Mountain Spotted Fever (RMSF) in order to offer an innovative method of teaching to promote and facilitate learning about RMSF. This methodological study used diagnosis, instructional planning, didactic design, revision, validation, and production of the technology. The analysis and diagnosis were carried out based on an extension activity in education and health related to RMSF at the Campus-USP, Ribeirão Preto (2014-2015). In the instructional planning, we defined that the Educational Technology would be presented in the form of an Interactive Laboratory, with learning stations. The Laboratory production counted with a multidisciplinary team collaboration involving researchers, nurses, electrician, carpenter, plastic artist, tailor and designer. The revision and validation process was divided in appearance and content validation and semantic validation. The appearance and content validation was carried out by 9 (nine) judges, with experience in biology and education areas. The semantic validation was performed by 8 (eight) undergraduates from nursing and pedagogy courses. The results of the appearance and content validation showed a CVI greater than 0.8 to the majority of the variables. In the semantic validation, the Laboratory presented a good acceptance and understanding by the participants, thus maintaining the same organization and content. We considered that the trajectory used for the elaboration of the Interactive Laboratory on RMSF confers academic and scientific support to the constructed product and contributes with its pedagogical potential as a resource that can provide significant learning; furthermore, it contributes with health practices transformation.
