The deaths of six lactating cows with similar clinical conditions\u2014characterized by hyporexia, hypogalactia, and recumbency\u2014had been reported from one property. Initially, two animals were examined and diagnosed with trypanosomiasis through identification of the protozoan in a blood smear. After the initial diagnosis, all lactating cows (n=37) on the property were examined, and blood samples were collected for tests including whole blood smear, buffy coat smear, Woo's technique, enzyme-linked immunosorbent assay (ELISA), and polymerase chain reaction (PCR). Woo's test, buffy coat smears, and whole blood smears indicated that 4\/37 (10.81%) animals were positive for trypanosomiasis, whereas ELISA and PCR indicated that 33\/37 (89.19%) and 27\/37 (72.97%) animals, respectively, were positive. The agreement obtained between parasitological techniques was classified as high, while between ELISA and PCR, no agreement. In conclusion, parasitological techniques have a low capacity to identify infected animals in the chronic stage of T. vivax infection. Therefore, techniques such as PCR and\/or ELISA should be used to minimize the occurrence of false negatives.<\/jats:p>","DOI":"10.1590\/s1984-29612022007","type":"journal-article","created":{"date-parts":[[2022,2,25]],"date-time":"2022-02-25T12:27:55Z","timestamp":1645792075000},"source":"Crossref","is-referenced-by-count":8,"title":["Evaluation
