description ABSTRACT The objective of this study was to obtain data on the occurrence of Babesia bigemina e Anaplasma marginale in cattle with characteristic clinical signs of the disease, in different properties in western Santa Catarina. For this, 149 blood sample were collected and slides smears were done and the staining with the Romanowsky kind dye subsequently. Of the 149 samples surveyed, 78 (52.35%) were positive for A. marginale, 04 (2.68%) for B. bigemina, and 03 (2.01%) samples showed co-infection. All described cases occurred in adult animals, from two years old, with Holstein females the highest occurrence represented 119/149 (79.86%). Regarding the presence of ectoparasites, hematophagous flies were observed in all properties and ticks in 58/149 (38.92%) animals. The results showed a higher occurrence of A. marginale, evidencing the need to seek strategies of control and prevention by the veterinary professionals, especially in moments of greater occurrence of the vectors. The confirmation as from laboratory support by stained blood smears beyond being cheaper practical is a method that helping professionals identify the suspected cases etiology. Moreover, based on this information, we can promote the elaboration of prevention and treatment strategies based on simple and fast diagnostic techniques, focused on especific disease agents. RESUMO O objetivo desse estudo foi obter dados de ocorrência B. bigemina. e A. marginale em bovinos com sinais clínicos característicos da doença em diferentes propriedades da região oeste de Santa Catarina. Para isso, foram coletadas 149 amostras de sangue, para posterior confecção de esfregaço em lâminas e a realização da coloração com o corante tipo Romanowsky. Das 149 amostras pesquisadas, 78 (52,35%) foram positivas para A. marginale, 04 (2,68%) para B. bigemina e 03 (2,01%) amostras apresentaram co-infecção. Todos os casos descritos ocorreram em animais adultos, a partir de dois anos de idade, com maior ocorrência em fêmeas da raça holandesa 119/149 (79,86%). Quanto à presença de ectoparasitas, foram observadas moscas hematófagas em todas as propriedades e carrapatos em 58/149 (38,92%) animais. Os resultados demonstram uma maior ocorrência de A. marginale evidenciando a necessidade dos profissionais buscarem estratégias de controle e prevenção, principalmente nas épocas de maior ocorrência dos vetores. A confirmação a partir do suporte laboratorial, por esfregaço de sangue corado, além de prático e barato, é um método
