BENAVIDES ORTIZ, Efraín et al. Therapeutic effect of an anaplasmicid and ant-protozoa product against the blood parasites of cattle. Ces. Med. Vet. Zootec. [online]. 2012, vol.7, n.1, pp.33-48. ISSN 1900-9607.

In Colombia all cattle raising areas located in tropical areas of low and medium altitude are considered endemic for haemoparasites of cattle, but sometimes losses are minimized by the development of immunity and the achievement of a state of equilibrium in populations. Generally, in the field the use of effective drugs is required as a help in the control of clinical manifestations associated with the occurrence of these diseases. This study was aimed to validate the benefit of the use of an anaplasmicid and anti-protozoa product (Ganaplus^®) for the control of clinical events associated with blood parasites in cattle. The study consisted of a experimental phase based on artificial inoculation of cattle with Anaplasma marginale, Babesia bigemina and Babesia bovis; and a field phase that evaluated clinical events in animals raised in endemic areas. In both phases, blood sample collection and measurement of body temperature were conducted. Complete hemogram, hematocrit, and blood smears for parasite analysis were performed. Cattle of the experimental phase showed very low parasitemia, with slight changes in hematologic parameters, but the animals that demonstrated clinical acute states successfully responded to the application of the compound, restoring their hematologic parameters. The cattle of the field phase showed higher parasitemias, with clear reductions in the hematocrit and the presence of an acute clinical syndrome, which responded appropriately to the product application. It was confirmed that the compound tested is a good medicine for the treatment of clinical disease associated with blood parasites.
