Lasit fáddágilkoriid | Čoahkkáigeassu: | Piroplasmosis and Anaplasmosis are hemoparasitic diseases caused by Babesia bovis or Babesia bigemina and Anaplasma marginale, respectively. These diseases have a high morbidity and mortality rate, cause a decrease in production and finally the death of the animals, generating an economic and sanitary problem in cattle herds. There are few studies that estimate the prevalence, spatial distribution and climatic factors associated with the presence of these diseases, so it is necessary to determine their geolocation and the influence that climate has on their presentation. The present study is a cross-sectional observational study with a spatial approach. To determine the influence of the independent variables on the dependent variables, logistic regression models were used and represented in risk maps. The free statistical program R version 4.2.0 was used. Of the 241 blood samples, 73.03% were determined for the presence of Anaplasma spp. and 44.81% for Babesia spp. The important climatic factors selected by the models were the precipitation of the wettest month and precipitation of the driest month, however, they were not significant (p>0.05), therefore, they had no influence on the presence of the diseases. In the spatial part, there was correlation with a Moran Index for Anaplasmosis between 0.07 and -0.48 and for Piroplasmosis between 0.05 and -0.36, however, the predictions were similar both with the model without spatial effect and with the model with spatial effect. In conclusion, a high prevalence of Piroplasmosis and Anaplasmosis was determined, confirming that the study area is endemic due to the presence of the vectors and the fact that the animals possibly develop immunity.
