The aim of this study was to detect Anaplasma phagocytophilum in horses from the province of Chiclayo, Peru, using haematological techniques. One hundred blood samples were collected from apparently healthy horses with a history of exposure to ticks. The haematological study consisted of blood count and the evaluation of blood smears stained with Wright and acridine orange to search for inclusion bodies and morulae of the pathogen. Results showed that 9% of horses (9/100) presented structures compatible with inclusion bodies or morulae of A. phagocytophilum, so they were considered as "positive". This group of animals presented slight alterations in the leukocytic and thrombocytic series. The findings indicate the presence of A. phagocytophilum in horses in Peru.

The aim of this study was to determine the presence of canine anaplasmosis by haematological findings (evidence of inclusion bodies or morulae in blood smear plus thrombocytopenia) and the presence of antibodies against Anaplasma spp in dogs with a history of ticks from the Chiclayo district (Lambayeque, Peru). Blood samples (n=88) were collected from apparently healthy dogs with a history of ticks. The haematological findings showed that 2.3% (2/88) of dogs were positive (with inclusion bodies or morulae plus thrombocytopenia) being compatible with A. platys. In addition, 22.7% (20/88) seropositivity against Anaplasma spp and a multiple seropositivity of 21.6% (19/88) with Ehrlichia spp were detected by the SNAP 4Dx Plus Test. Positive and seropositive dogs showed thrombocytopenia and, to a lesser extent, anaemia, leucocytosis and leukopenia. The results showed presence of subclinical c...
