“…Canine ehrlichiosis has been reported from subtropical and tropical areas of the world where it is one of the very common disease reported during veterinary practice in dogs (Rani et al 2011). One of the major reasons for the common occurrence of E. canis is the tick vector, Rhipicephalus sanguineus sensu lato, which is common in rural and urban areas in tropical and subtropical areas of the world (Aguiar et al 2007;Dantas-Torres 2008;Aktas 2014;Aktas et al 2015). 1 These two authors have contributed equally to the manuscript.…”

Canine monocytic ehrlichiosis is a tick-borne disease caused by an intracellular alpha-proteobacterium, Ehrlichia canis, which replicates within mononuclear cells in the host. This study was designed to use a polymerase chain reaction (PCR) protocol for the molecular detection of E. canis by the amplification of a portion of its 16S rRNA gene, as well as the effects of this alpha-proteobacterium on the haematological parameters of the sampled dogs and the risk factors associated with E. canis infection. A total of 151 blood samples were collected from dogs of various breeds at three sampling sites (Lahore, Rawalpindi/Islamabad and Multan) in Punjab, Pakistan. Data regarding the epidemiological factors (including age, gender, breed, body temperature, deworming, vaccination, mucous membrane status, hydration status, the presence of haematuria and tick infestation) were collected through a questionnaire at the time of sample collection. A 400 bp DNA fragment of the 16S rRNA gene of E. canis was amplified from 42 dog blood samples (28% of the total), [Lahore (N = 24), Rawalpindi/Islamabad (N = 13) and Multan (N = 05)] through PCR. Data analysis revealed that the character of the animals (age, sex and breed) had no significant association (P > 0.05) with the presence of E. canis. Various haematological parameters were also compared, and the results revealed that all of the parameters remained unaffected, except significantly lower white blood cell counts (P = 0.004) in E. canis-positive blood samples, as compared with the control group. We concluded that this is the first molecular confirmation of canine infection by E. canis using PCR. Moreover, no specific epidemiological parameter was found associated with the prevalence of E. canis in dogs.

“…Canine monocytic ehrlichiosis (CME) is a disease caused by Ehrlichia canis (Rickettsiales: Anaplasmataceae), a Gram-negative, obligate intracellular bacteria transmitted by the tick vector Rhipicephalus sanguineus, commonly known as the "brown dog tick" (1) . Some dogs are asymptomatic, and for others, the clinical manifestations are nonspecific and often involve different systems.…”

“…Canine babesiosis, which is caused by Babesia vogeli (Piroplasmorida: Babesiidae) and transmitted by the tick R. sanguineus, is a common disease in tropical areas (1) . The disease usually causes fever, lethargy, anorexia, and jaundice, and clinicopathological abnormalities typically found include regenerative immune-mediated hemolytic anemia, nonregenerative anemia, leukocytosis, leucopenia, and thrombocytopenia (6) .…”

“…A study on parasitic ectofauna in a canine population in the city of Lavras, Minas Gerais, showed that R. sanguineus is the main ectoparasite in urban, indoor dogs (11) , and this tick is the vector of E. canis and B. vogeli (1) . However, despite the importance of ehrlichiosis and babesiosis to veterinary clinical practice, there is no information on the seroprevalence of E. canis and B. vogeli in the population of dogs that are attended at the veterinary hospital in Lavras.…”

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. Os resultados sorológicos deste estudo sugerem que a Cienc. anim. bras., Goiânia, v.18, 1-9, e-36095, 2017 2 FONSECA, J.P., et al.infecção por E. canis e B. vogeli é endêmica na população canina em questão, com uma prevalência da fase subclínica (assintomática) em cães soropositivos para erliquiose ou babesiose.

“…High levels of infestation of brown dog tick can cause skin irritation and damage in dogs, and the population can reach pest proportions in houses and kennels. Rhipicephalus sanguineus can vector disease organisms of zoonotic concern in dogs-canine ehrlichiosis (Ehrlichia canis) (Fourie et al 2013), canine babesiosis (Babesia canis) (Lord 2014), Coxiella burnetii, Rickettsia conorii, and Rickettsia rickettsia (Dantas-Torres 2008).…”
