“…This group of bacteria attaches to the surface of red blood cells, where it then grows. Infection by M. haemocanis has been documented in dogs in the USA, Europe, Canada, the United Kingdom (Seneviratna et al 1973;Chalker 2005), and Brazil (Trapp et al 2006), although few epidemiological data are found. The PCR assay used in the present study was originally developed for the detection of Mycoplasma haemofelis in cats (Messick et al 1998) and was later successfully used to detect M. haemocanis in a dog (Brinson and Messick 2001).…”

To identify DNA of the main tick-borne pathogens in dogs from Recife (Brazil), polymerase chain reactions were carried out on blood samples of dogs treated at the Veterinary Hospital of the Universidade Federal Rural de Pernambuco from March 2007 to June 2008. The detection of DNA was performed using specific primers. Amplicons were analyzed through electrophoresis and sequencing. A phylogenetic tree was constructed using the UPGMA method, revealing that the sequences were closely related to those of strains from other geographic regions. Among the 205 blood samples analyzed, 48.78% was positive for Anaplasma platys; 38.04% was positive for Ehrlichia canis; 7.31% was positive for Babesia canis vogeli; and 0.49% was positive for Hepatozoon canis and Mycoplasma haemocanis. Coinfection of two or three pathogens was found in 23.9% (49/205) of the dogs. The subspecies B. canis vogeli was identified. Infection by H. canis and M. haemocanis is reported for the first time in dogs in the state of Pernambuco (Brazil). The data indicate that the main tick-borne pathogens in dogs in this region are E. canis and/or A. platys, followed by B. canis vogeli.

“…This prevalence is similar to that (2.9%) reported in I. ricinus collected in southern Germany, although peak prevalence in city parks may reach around 10% (Silaghi et al 2008) M. haemocanis Seventeen dogs from Romania and one from Hungary were tested positive for M. haemocanis-DNA by PCR. M. haemocanis is transmitted by the brown dog tick R. sanguineus and is often found in immunocompromised and splenectomized dogs (Seneviratna et al 1973;Kemming et al 2004;Willi et al 2010). To our knowledge, this is the first report on this agent in dogs from Romania and Hungary.…”

Canine arthropod-borne infections are of major interest in small animal practice and have been widely investigated in Central and Western Europe. However, only limited epidemiological data are available from South-Eastern European countries, although diseases including babesiosis or dirofilariosis are widely recognised as important canine infections in these countries. A steadily increasing number of dogs imported from South-Eastern Europe into Germany require particular attention by small animal practitioners. In this study, a total of 216 dogs [29 local Romanian pet dogs presented at Salvavet Veterinary Clinic in Bucharest, Romania, and 187 imported stray dogs from Romania (n = 109) and Hungary (n = 78) into Germany] were screened by molecular biological, serological and haematological methods for canine arthropod-borne infections. Eleven different parasitic and bacterial vector-borne pathogens-Babesia canis canis, Babesia canis vogeli, Babesia gibsoni, Babesia felis-like, Hepatozoon canis, Leishmania spp., Dirofilaria immitis, Dirofilaria repens, Acanthocheilonema reconditum, Anaplasma phagocytophilum and Mycoplasma haemocanis-were detected. Fifty-six percent of the dogs were positive by direct methods. B. canis canis was the most prevalent pathogen in dogs imported to Germany (42.8%) and dogs submitted for clinical consultation in Bucharest (44.8%). Our data strongly suggest the introduction of an adjusted screening panel in dogs from South-East Europe in view of increasing importation of dogs into Germany.

“…Infections are usually chronic and subclinical in immunocompetent dogs but may lead to clinical signs related to haemolytic anaemia following splenectomy, immunosuppression or concurrent infections [2]. Although the natural mode of transmission of feline and canine haemoplasmas has not been definitely elucidated, blood transfusions and blood-sucking arthropods such as ticks have been implicated to be involved in the transmission of haemoplasmas in dogs and cats [3–5]. Since dogs in Korea are expected to be frequently exposed to arthropod infestation during their outdoor activities, they are also vulnerable to the infection with haemotropic mycoplasmas.…”

BackgroundPrevious surveys in dogs from Korea indicated that dogs are exposed to a variety of vector- borne pathogens, but perception for a nation-wide canine vector-borne disease (CVBD) occurrence has been missing. We report here results of both serological and molecular prevalence studies for major CVBDs of dogs from all over the South Korean Peninsula except for Jeju Island.ResultsSerological survey of 532 outdoor dogs revealed the highest prevalence for Dirofilaria immitis (25.2%), followed by Anaplasma phagocytophilum (15.6%), Ehrlichia canis (4.7%) whereas Borrelia burgdorferi showed the lowest prevalence (1.1%). The number of serologically positive dogs for any of the four pathogens was 216 (40.6%). Concurrent real-time PCR assay of 440 dogs in the study indicated that DNA of “Candidatus M. haematoparvum”, Mycoplasma haemocanis, Babesia gibsoni, A. phagocytophilum, and Hepatozoon canis was identified in 190 (43.2%), 168 (38.2%), 23 (5.2%), 10 (2.3%) and 1 (0.2%) dogs, respectively. DNA of Bartonella spp., Ehrlichia spp., Leishmania spp., Rickettsia spp. and Neorickettsia risticii was not identified. Analysis of questionnaires collected from owners of 440 dogs showed that the number of dogs with heartworm preventive medication was 348 (79.1%) among which dogs still positive to D. immitis infection were 60 (17.2%), probably due to the mean months of heartworm preventive medication being only 6.5. The high prevalence rates of both “Ca. M. haematoparvum” and Mycoplasma haemocanis in dogs from Korea indicate that these organisms may be transmitted by vectors other than Rhipicephalus sanguineus because this tick species has rarely been found in Korea. This is the first nationwide survey for canine haemotropic mycoplasma infections in Korea.ConclusionsThis study showed that the risk of exposure to major vector-borne diseases in dogs is quite high throughout all areas of South Korean Peninsula. Since achieving full elimination of many pathogens causing CVBDs from infected animals is often impossible even when they are clinically cured, dogs once exposed to CVBDs can remain as lifetime reservoirs of disease for both other animals and humans in the close vicinity, and should therefore be treated with preventative medications to minimise the risk of pathogen transmission by the competent vectors.
