Giemsa-stained blood smears were negative for blood  parasites. A total of 94 % of the cattle were sero-positive for Babesia  bigemina by indirect fluorescent antibody test while 87 % were sero-positive  for Anaplasma by enzyme-linked immunosorbent assay. The observation of  negative blood smears but high incidence of positive serological results for  Anaplasma and Babesia for the same group of cattle indicates that  this area is endemic for these diseases but with a stable disease situation. All  the animals were sero-negative for B. bovis and this is probably because  the tick vector (Boophilus microplus) which transmits the disease is not  present in the Free State Province. Two tick species belonging to the family  Ixodidae were found on cattle, namely Boophilus decoloratus and  Rhipicephalus evertsi evertsi. In the present study significant  differences in seasonal burdens of B. decoloratus occurred, with the  highest infestations recorded from February to June. The presence of R.  evertsi evertsi throughout the year without any or with small fluctuations  in winter months was observed, with a peak from February to May<\/jats:p>","DOI":"10.4102\/ojvr.v71i1.287","type":"journal-article","created":{"date-parts":[[2012,8,27]],"date-time":"2012-08-27T03:22:23Z","timestamp":1346037743000},"source":"Crossref","is-referenced-by-count":21,"title":["A sero-epidemiological survey of blood parasites in cattle in the north-eastern Free State, South Africa"],"prefix":"10.4102","volume":"71","author":[{"given":"M.S.","family":"Mtshali","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.T.","family":"De Waal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.A.","family":"Mbati","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2580","published-online":{"date-parts":[[2004,11,8]]},"container-title":["Onderstepoort J Vet Res"],"original-title":[],"link":[{"URL":"http:\/\/ojvr.org\/index.php\/ojvr\/article\/viewFile\/287\/266","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,1]],"date-time":"2017-06-01T07:22:01Z","timestamp":1496301721000},"score":1,"resource":{"primary":{"URL":"http:\/\/ojvr.org\/index.php\/ojvr\/article\/view\/287"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,11,8]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2004,11,8]]}},"URL":"https:\/\/doi.org\/10.4102\/ojvr.v71i1.287","relation":{},"ISSN":["2219-0635","0030-2465"],"issn-type":[{"value":"2219-0635","type":"electronic"},{"value":"0030-2465","type":"print"}],"subject":[],"published":{"date-parts":[[2004,11,8]]}}}
