“…Thus, E. canis infection cannot be definitively established until genetic characterization is done. Moreover, anaplasmosis in dogs are provoked by Anaplasma phagocytophilum, which has been identified in granulocytes (Pusterla et al 1997;Breitshwerdt et al 1998), and Anaplasma platys, which is transmitted by R. sanguineus and infects platelets (Kontos et al 1991;Brown et al 2001). More recently, we have detected A. platys in R. sanguineus and A. phagocytophilum in Ixodes ricinus (Sarih et al 2005) in Tunisia.…”

A seroepidemiological survey was conducted in five bioclimatic areas of Tunisia to determine the prevalence of antibodies to Ehrlichia canis and Anaplasma phagocytophilum antigens, surrogate markers of the agents of canine monocytic ehrlichiosis (CME) and canine granulocytic ehrlichiosis, respectively. Among 286 collected sera, 54.2% and 25.2% were seropositive for E. canis and A. phagocytophilum, respectively, by the indirect immunofluorescence antibody (IFA) test. Clinical and hematological tests were done only for 58 sick dogs from Tunis area. A reverse line blot (RLB) hybridization was then used to identify isolated Ehrlichia and Anaplasma species infecting dogs (n = 228). Among them, only two dogs were infected by A. phagocytophilum; ten sample dogs were demonstrated infected by E. canis and ten infected by Ehrlichia sp., from which one dog showed a mixed infection with A. phagocytophilum and E. canis and one with A. phagocytophilum and Ehrlichia sp. RLB findings were confirmed by sequencing; BLAST search against GenBank revealed high similarity of the sequence of Ehrlichia sp. PCR/RLB amplicons with Anaplasma platys 16S rRNA partial sequence.

“…Follicular hyperplasia of lymph nodes and plasmacytosis have been observed in the acute phase of infection, and some organs, such as spleen, may develop hemorrhage (3). Clinical cases of canine infectious cyclic thrombocytopenia have been reported throughout the world including the United States (11,17), Greece (15), France (4), Taiwan (8), Spain (21), Southern China (13), Australia (6) and Thailand and Venezuela (24). A. platys cannot be cultured and is even difficult to detect in vivo because of cyclic and often low levels of organisms (10).…”

Blood specimens from clinically normal military dogs and their trainers, in Lara, Venezuela were screened for Anaplasma platys, A. phagocytophilum, or Ehrlichia ewingii using 16S rRNA PCR tests. Sixteen percent (7/ 43) of dog specimens were positive by A. platys PCR test followed by sequencing of the PCR products, and all human blood specimens [25] were negative. All specimens from these dogs and humans were PCR negative for E. ewingii or A. phagocytophilum. Twelve Rhipicephalus sanguineus ticks removed from these dogs were negative for A. platys by reverse transcription PCR test. Almost the entire 16S rRNA gene (1,364 bp) and groESL operon (1,646 bp) sequences of A. platys isolated from a dog were determined, revealing that both sequences were closely related to the sequences of an A. platys strain detected in R. sanguineus ticks from the Democratic Republic of Congo.

“…Recently, A. platys was found in R. turanicus and Dendrobates auratus, as well [19,43]. Regarding the geographic distribution of A. platys, molecular detection of A. platys in dogs was reported in countries in different continents including America [44,45], Europe [46], Asia [47], Oceania [48], and Africa [31].…”

Canine vector-borne diseases constitute a large group of diseases transmitted by arthropods with worldwide distribution. A wide range of bacterial, viral, and parasitic agents that are transmitted by vectors cause disease to dogs, many of which can also affect humans and thus have an important zoonotic potential. Bacterial agents that are transmitted by vectors have been considered less important than viral or parasitic agents and are not commonly discussed in companion animal practice. However, close contact between pet animals and people offers favorable conditions for transmission of these bacteria. Many of these diseases have become a focus of interest for scientists in recent years. Increase in reservoir abundance, climate change, changing habitat structure, socio-political changes, and imports of dogs for welfare reasons and trade as well as traveling are considered to be potential factors for the pathogens and vectors introduction into new areas. Apart from, the veterinary aspect of these diseases, domestic dogs could play a central epidemiological role in the transmission of bacterial agents to humans, acting as reservoirs and sentinels, a circumstance that requires a One Health approach. This review highlights the most important of these bacterial agents, presenting updated current knowledge with special reference to treatment approach and One Health aspect.
