“…O ectoparasita mais prevalente foi o R. sanguineus, presente em 133 (77,7%) cães, sendo esta a única espécie de carrapato encontrada neste estudo, concordando com os resultados obtidos por Soares et al (2006) e Guimarães et al (2011) em cães procedentes da área urbana de Juiz de Fora e de Lavras/MG, respectivamente. Silva et al (2017), por sua vez, constataram em estudo no estado do Paraná que todos os cães infestados por R. sanguineus, 23/56 (41%), provinham de área urbana, mas também observaram a presença de outro ixodídeo, o Ambliomma aureolatum, em 13/56 (23%) cães da mesma área.…”

“…Desta forma, os elevados índices de infestação por R. sanguineus e C. felis felis relacionam-se fortemente ao clima quente e úmido da região, que constituem as condições ideais para estes parasitos (SILVA et al, 2016). Por meio deste estudo, confirma-se a predominância da referida espécie de ixodídeo em cães da área urbana do município de Rio Branco/AC, concordando com estudos similares realizados em demais estados brasileiros (SOARES et al, 2006;GUIMARÃES et al, 2011;SILVA et al, 2017).…”

RESUMO Inúmeros estudos relacionados à frequência das infestações por ectoparasitas vêm sendo realizados no Brasil e no mundo, porém não foram encontrados registros no Estado do Acre. Com o objetivo de estudar a epidemiologia das ectoparasitoses em cães domiciliados e errantes da área urbana do município de Rio Branco, Acre, foram coletados, sob inspeção visual, espécimes de ectoparasitas de cães para posterior identificação das espécies. Foram obtidas amostras de 171 animais parasitados, sendo 81 (47%) domiciliados e 90 (53%) não domiciliados, e 77 (45%) machos e 94 (55%) fêmeas. Quanto às infestações, 124 (73%) caracterizaram-se como simples e 47 (27%) como mistas. Foram identificadas sete espécies de ectoparasitas, entre carrapatos, pulgas, piolhos e ácaros causadores de sarna. A infestação por Rhipicephalus sanguineus foi a mais frequente, encontrada em 133 (77,7%) animais, seguida por Ctenocephalides felis felis que esteve presente em 50 animais (29%). Ainda, 20 animais (12%) apresentaram infestação por Otodectes cynotis, 15 (8,5 %) por Heterodoxus spinger, cinco (3%) por Demodex canis e o índice de um (1,1%) animal se repetiu tanto para a prevalência de com Sarcoptes scabiei como de Trichodectes canis. PALAVRAS-CHAVE: cães, carrapatos, parasitoses.

“…In Brazil, the rate of infestation by R. sanguineus ticks in dogs is high (SILVA et al, 2017), especially in urban areas; therefore, it logically follows that there would be a higher potential for mycoplasmosis. However, the incidence of the disease is generally low when compared to other pathogens transmitted by ticks such as Anaplasma platys, Babesia vogeli, and Ehrlichia canis (RAMOS et al, 2010).…”

Haemotropic mycoplasmas are pleomorphic, epicellular, gram-negative bacteria, which infect red blood cells. In dogs, the acute phase of this infection may lead to haemolytic anaemia potentially precipitated by splenectomy, or by immunosuppressive drugs or diseases; however, in cases of chronic infection, the signs are inapparent. Molecular techniques and microscopic observation are the most commonly used methods to diagnose mycoplasma infection, though studies about haemotropic mycoplasma infections in dogs from Cuiabá, capital of Mato Grosso, Brazil are scarce. The objective of this study was to evaluate the frequency of mycoplasma infection, the Mycoplasma species present, and factors associated with infection in 334 dogs diagnosed using polymerase chain reaction (PCR). The frequency of infection was 5.4%, and M. haemocanis was the only species identified. No epidemiological factor investigated showed a statistically significant association with infection, including tick infestation.

“…All animals tested were negative, this result was expected since the A. aureolatum vector is not yet found in Londrina (Labruna, Guimarães, Pacheco, Pinter, & Gennari, 2001). However, studies carried out by B. R. Silva et al (2017), in the metropolitan mesoregions of Curitiba, Central and South Center of Paraná state have identified the A. aureolatum vector in the following cities: Cascavel, Ponta Grossa, Guarapuava, Castro, Carambeí, Campo Largo, Campina Grande do Sul and São José dos Pinhais.…”

There is an increase in tick-borne diseases in dogs in urban and rural areas in Brazil and some of these are of public health importance. Rhipicephalus sanguineus-transmitted hemoparasitoses are the main causes of mortality in dogs. The present study investigated the molecular occurrence of Ehrlichia canis, Babesia vogeli and Anaplasma platys in dogs with clinical sings and hematological abnormalities suggestive of tick-borne diseases. These dogs were seen at a Veterinary Hospital of a Public University between January 2014 and December 2016, and were evaluated through anamnesis, clinical examination and complementary exams. The polymerase chain reaction technique was used to detect the presence of hemoparasites DNA. From the 461 dogs that were tested for B. vogeli, 10.6% (49/461) were positive, the associated variable was age. Regarding the 730 animals screened for E. canis, 15.1% (110/730) were positive, and the infection was associated with hematocrit and number of platelets. Relative to the 86 samples evaluated for A. platys, 15.1% (13/86) were positive, and no variable presented statistical significance. From the animals positive for B. vogeli, no of these showed positivity by qPCR for Rangelia vitalii. It is concluded that the occurrence of hemoparasitosis in dogs from the Londrina region is common. Therefore, it is emphasized that molecular techniques should be used as an auxiliary tool for the differential diagnosis of the different etiological agents causing hemoparasitosis. Additionally, these molecular tools are essential for better investigation and preventive assertiveness because it allows to detect parasite DNA.
