“…However, in studies with dogs older than one or two years of age, the dogs have a higher frequency of anti-B. vogeli antibodies (7) and clinical disease (27) . A study evaluating the mode of infection revealed that dogs with only indoor access have a lower frequency (P<0.05) of infection by E. canis (17) , most likely due to the close interaction with their owners.…”

The aim of this study was to determine the prevalence of anti-Ehrlichia canis and anti-Babesia vogeli IgG antibodies in dogs and correlate this prevalence with risk factors to evaluate the relation of serological status to hematological findings. Blood samples of dogs attended from September 2011 to March 2012 at the veterinary hospital of the Federal University of Lavras, Brazil, were analyzed using an indirect fluorescence antibody test (IFAT). Of the total 160 dog serum samples, 23.7% (38 dogs; CI 95 17.7% -30.7%) were seropositive for E. canis, 40.0% (64 dogs; CI 95 40.0% -59.2%) for B. vogeli, and 5.6% (9 dogs) for both hemoparasites. None of the epidemiological variables showed a significant association (P>0.05) with seropositivity to E. canis and B. vogeli. Dogs seropositive for E. canis showed lower values for hematocrit (P<0.05). However, for the erythrogram, the platelet count, the leukogram and clinical signs, no significant difference (P>0.05) was observed between dogs that were seropositive and seronegative for E. canis or for B. vogeli. Serological results suggest that infection with E. canis and B. vogeli is endemic in the canine population in question, with a prevalence of the subclinical phase (asymptomatic) in dogs that are seropositive for ehrlichiosis or babesiosis. Keywords: babesiosis; canine; ehrlichiosis; IFAT; laboratory findings. ResumoO objetivo deste estudo foi determinar a prevalência de anticorpos IgG anti-Ehrlichia canis e antiBabesia vogeli em cães e correlacionar com a prevalência e fatores de risco para avaliar a relação do estado sorológico com os achados hematológicos. Amostras de sangue de cães coletadas de setembro de 2011 a março de 2012, no Hospital Veterinário da Universidade Federal de Lavras, Brasil, foram analisadas usando o teste de reação de imunofluorescência indireta (RIFI). Do total de amostras de soro de 160 cães, 23,7% (38 cães; IC95 17,7% -30,7%) foram soropositivos para E. canis, 40,0% (64 cães; IC95 40,0% -59,2%) para B. vogeli, e 5,6% (9 cães) para os dois hemoparasitas. Nenhuma das variáveis epidemiológicas mostrou associação significativa (P> 0,05) com a soropositividade para E. canis e B. vogeli. Cães soropositivos para E. canis mostraram valores médios mais baixos para hematócrito (P<0,05). No entanto, para o eritrograma, a contagem de plaquetas, o leucograma e os sinais clínicos, nenhuma diferença significativa (P> 0,05) foi observada entre cães soropositivos e soronegativos para E. canis ou para B. vogeli.

“…Little is known about the possible risk factors associated with canine babesiosis in Brazil (DANTAS-TORRES; FIGUEREDO, 2006). Therefore, due to the importance of this disease for small animal veterinary practice, the aim of this work was to determine the occurrence of Babesia canis vogeli in dogs from Recife, Pernambuco, through molecular detection and parasitological tests.…”

Parasitological and molecular detection of Babesia canis vogeli in dogs of Recife, Pernambuco and evaluation of risk factors associated

This work aims to detect the presence of Babesia canis vogeli in dogs from Recife, Pernambuco via molecular and parasitological detection methods, and to assess the risk factors associated with this parasite. A total of 146 dogs (male and female) of varying breeds and ages that presented clinical symptoms of babesiosis were assessed at a clinical care center in the Veterinary School Hospital. Blood was obtained via venopuncture for hemoparasite detection and polymerase chain reaction (PCR). Using a commercial kit, DNA was extracted from blood samples. For the PCR reaction, an approximately 590 base pair long genetic sequence was used to detect the presence of B. canis vogeli. The forward primer, denoted as BAB1 (5'-GTG AAC CTT ATC ACT TAA AGG-3'), was specific for a conserved region on the 18S rRNA gene of Babesia spp., and the antisense primer was denoted as BAB4 (5'-CAA CTC CTC CAC GCA ATC G-3'). PCR results suggested that the percentage of Babesia canis vogeli infection was 4.8%. Through descriptive statistical analysis of the data, we observed that there was higher frequency of parasite infection associated with male dogs above two years of age, with a defined breed, from the countryside, are domiciled, and also suffer from tick infestation. We conclude that regardless of the type of risk factor, babesiosis can be found throughout Recife, Pernambuco, and its prevalence does not vary in most regions of Brazil. Our results indicate that PCR is a sensitive test for the detection of blood parasites, and should be performed as a clinical routine.

“…This species infests dogs, coyotes, foxes and wolves in different regions from America (7), whereas in Europe (Check Republic), it has been found on Nyctereutes procyonoides (19), demonstrating its adaptability to parasites wild canids. Unlike T. canis, H. spiniger has also been found on cats and dogs, which are alternative hosts (20,21). These lice are primarily parasites of marsupials (e.g.…”

Objetive. To determine the distribution of ectoparasites in dogs in Panama. Materials and methods. There were surveyed 720 canines belonging to 57 communities. Results. The results showed that 84% of the dogs were infested with at least one species of ectoparasite. Dogs from lowlands showed a higher percentage of parasitism and a greater biodiversity of parasites than dogs from highlands. There were found seven species of ticks, four species of fleas, two species of lice, and one specie of botfly. The ticks Rhipicephalus sanguineus, Amblyomma cajennense, A. ovale and the flea Ctenocephalides felis were widespread; however Ixodes boliviensis and Pulex simulans showed a much narrower geographic distribution and they were found only in dogs from highlands. The flea species Rhopalopsyllus cacicus and the tick Haemaphysalis juxtakochi were found for the first time in panamanian dogs. Conclusions. The environmental situation in Panama, can encourage that wildlife ectoparasites parasitized dogs in absence of their native hosts. This condition may increase transmission risk of some diseases where the ticks and fleas are vectors. 2275 RESUMENObjetivo. Determinar la distribución de ectoparásitos de perros en Panamá. Materiales y métodos. Se examinaron 720 individuos en 57 comunidades. Resultados. Los resultados demostraron que el 84% de los perros presentaron al menos una especie de ectoparásito. Los perros de tierras bajas mostraron un mayor porcentaje de parasitismo y mayor biodiversidad de parásitos que los animales de tierras altas. Se encontraron siete especies de garrapatas, cuatro de pulgas, dos de piojos y una de mosca. Las garrapatas Rhipicephalus sanguineus, Amblyomma cajennense, A. ovale y la pulga Ctenocephalides felis mantuvieron una distribución más amplia; mientras que Ixodes boliviensis y Pulex simulans sólo se reportaron en tierras altas. La pulga Rhopalopsyllus cacicus y la garrapata Haemaphysalis juxtakochi se reportaron por primera vez en perros de Panamá. Conclusiones. La situación medioambiental en Panamá puede propiciar que la fauna de ectoparásitos parasiten perros ante la ausencia de hospederos nativos, esta condición puede aumentar el riesgo de transmisión de algunas enfermedades en las que las garrapatas y pulgas son vectores. Conservation of ectoparasites.The ectoparasites were preserved in 95% alcohol. Engorged ticks nymphs were collected and kept alive in plastic bottles plugged with cotton, and then placed in an incubator (average temperature of 29ºC and 80% of humity) until molt.
