“…In Brazil, previous studies have shown that the prevalence of CVBDs in dogs in urban areas has varied from absence to 91.2% (Lasta et al, 2013;Spolidorio et al, 2013;Vieira et al, 2013b). Although the neighborhood dogs of the present study had comparatively lower CVBD prevalence (Vieira et al, 2013b;Azzag et al, 2015), the wide differences in CVBD prevalence may be explained by the populations studied, lifestyles, environmental occurrence of vectors and diseases, diagnostic tests used and vector competence of ticks from the Rhipicephalus sanguineus group (Balakrishnan et al, 2014;Maia et al, 2015;Moraes-Filho et al, 2015). As observed here, infection by CVBDs may occur in the absence of clinical signs (Joppert et al, 2001;Maggi et al, 2014;Azzag et al, 2015) or hematological changes (Novacco et al, 2010;Balakrishnan et al, 2014;Moraes-Filho et al, 2015).…”

A previous study on owned dogs did not show any significant associations between hemoplasma infection and anemia, ectoparasite infestation, gender and clinical status (Tennant et al, 2011), thus corroborating the findings from the neighborhood dogs of the present study.…”

“…Despite the WHO definition published 25 years ago, this was the first study to survey health status and CVBDs in neighborhood dogs, to the best of the authors' knowledge. Since these dogs may have spent their time continuously roaming outdoors, their exposure to vectors and pathogens was expected to be relatively higher than that of owned dogs (Azzag et al, 2015). Surprisingly, despite lacking traditional ownership, these dogs were found to be healthy on clinical examination, with CBC counts and biochemical profiles within the normal range, and they mostly tested negative for CVBD.…”

Neighborhood dogs may act as reservoirs and disseminators of vector-borne diseases in urban areas. Accordingly, the aim of this study was to ascertain the health status and the vector-borne pathogens infecting dogs living in public areas with high levels of human movement in the city of Curitiba, southern Brazil. Blood samples from 21 neighborhood dogs that were found in nine of 22 bus stations and two public parks were subjected to a complete blood cell (CBC) count, serum biochemical profiling, a commercial rapid ELISA test and a commercial real-time PCR panel of vectorborne diseases. The CBC count and serum biochemical profiling were within the normal range for dogs and only 1/21 (4.7%) of the dogs was seroreactive for Borrelia burgdorferi sensu stricto. The commercial real-time PCR panel showed that 7/21 (33.3%) of the dogs had Mycoplasma haemocanis infection, 9/21 (42.8%) had 'Candidatus Mycoplasma haematoparvum' and 4/21 (19.0%) had both. No statistical association between infected by the agents found here and abnormalities in physical examinations, laboratory tests or ectoparasite presence was found (p > 0.05).In conclusion, neighborhood dogs showed low prevalence of vector-borne diseases and satisfactory wellbeing, and dogs can be used as sentinels for disease exposure.

“…Serologic evidence of previous studies around the world indicated that E. canis is present among dogs throughout all continents, where serologic studies have found a prevalence ranging from 30 to 80% in some countries of Africa (Azzag et al, 2015;Inokuma et al, 2006;Eoghain and Raoult, 2004;Ndip et al, 2005;Davoust et al, 2006), whereas in some Asian countries it was of 0.2 to 30% (Inokuma et al, 1999;Rajamanickam et al, 1985;Stich et al, 2008).…”

Infection by Ehrlichia canis in dogs causes the worldwide tick-borne disease called canine monocytic ehrlichiosis (CME), and the presence of E. canis has been serologically demonstrated in all continents, with prevalence ranging from 0.2 to 80%. In southern Mexico, a prevalence of 44% was found, whereas in the northwest part of the country it varies from 21 to 49%. In the present study, a commercial kit for the detection of antibodies against E. canis was used in 391 dogs from the city of Monterrey, which is located at northeast of Mexico. A total of 54 samples were positive, giving a prevalence of 13%. According to sex, prevalence was 14% for males and 13% for females. Positive animals varied in age from 21 to 132 months old and only 10 of them presented ticks. As in the southern and northwest parts of Mexico, CME is present in northeast region, although with a lower prevalence.

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.
