Abstract
Tick-borne diseases are frequent in the southeastern section of Brazil. The most prevalent canine parasites diagnosed are Ehrlichia canis, Babesia gibsoni, Babesia canis, and Anaplasma platys, although Mycoplasma haemocanis and Candidatus Mycoplasma haematoparvum have also been detected in other regions of the country. Two clinically healthy dogs from a suburban area of the state of Rio de Janeiro had a history of being heavily infested with ticks and were examined at IDEXX Reference Laboratories, California for a tick panel check. One dog harbored DNA of Candidatus Mycoplasma haematoparvum and the other, the DNA of Mycoplasma haemocanis. These results reinforce the need for permanent monitoring for tick infestations and tick-borne parasites in southeastern Brazil, particularly considering the likely continuation of global climate changes that will contribute to the spread and increase of infections across the country.
Highlights
Tick infestations and tick-borne diseases are commonly diagnosed in Brazilian dogs, especially in those allowed to roam free outside of their homes (Juan szabó et al, 2001; Labarthe et al, 2003)
In Brazil, Ehrlichia canis, Babesia gibsoni, Babesia canis, and Anaplasma platys circulate among dogs in regions of the country where ticks are frequently reported (Moreira et al, 2003)
In the absence of clinical or hematological signs, DNA samples were sent for examination by a qPCR tick panel at the IDEXX Reference Laboratories in West Sacramento, California, USA
Summary
Tick infestations and tick-borne diseases are commonly diagnosed in Brazilian dogs, especially in those allowed to roam free outside of their homes (Juan szabó et al, 2001; Labarthe et al, 2003). Routine examination of dogs should always include a determination of whether the animal is or has been infected with tick-transmitted parasites. In Brazil, Ehrlichia canis, Babesia gibsoni, Babesia canis, and Anaplasma platys circulate among dogs in regions of the country where ticks are frequently reported (Moreira et al, 2003). Confirmed Mycoplasma haemocanis was first reported in 2003 (De Morais, 2003) and Candidatus Mycoplasma haematoparvum, in 2008 (Santos et al, 2008).
