TAPIA, Fernanda Baquero; MONROY, Byron Díaz  e  VELOZ, Pamela Vinueza. Study of neosporosis in cattle from the province of Chimborazo, Ecuador. Rev. Inv. Cs. Agro. y Vet. [online]. 2022, vol.6, n.17, pp.224-238.  Epub 27-Jun-2022. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v6i17.163.

Neosporosis is a parasitic disease of canine origin that causes abortion in cows and has a great economic impact. For this reason, it was proposed to determine the seroprevalence, infection mechanisms and economic losses that it causes. The study was carried out in five farms in the Province of Chimborazo, Ecuador, with Holstein and Jersey cattle, where the abortion rate was determined by analyzing reproductive records, using the Elisa technique in blood, antibodies to Brucella abortus and Neospora caninum were determined in 170 cows and 7 dogs belonging to the farms, to quantify the economic losses, a bibliographic model of veterinary epidemiology was used, the design of a health plan for prevention and control, allowed to train farmers. The results were that all the dogs analyzed were carriers of the parasite, locating as the primary source of infection towards the cows, 55.60% of these were positive, 105 corresponded to cows that aborted and of these, 70.88% developed antibodies to Neospora caninum, an economic loss of $552 was calculated for each abortion, which implies an annual loss of $8,987 per farm. As there is no effective treatment, it is recommended to eliminate seropositive animals and vaccinate healthy cows, which will help reduce abortions, in addition to treating dogs with Trimethoprim plus Sulfadiazine, or Clyndamycin.
