Abstract: The purpose of this study was to estimate the prevalence of Theileria equi in horses from central western region of Paraná state, Brazil. The presence of antibodies IgG against T. equi was determined in serum samples obtained from 400 team roping horses of the district of Guarapuava by the enzyme-linked immunosorbent assay (ELISA). Results showed that 242 (61%) animals were positive which demonstrates that equine piroplasmosis is widespread and therefore it might be a contributing factor for the irregular perf… Show more

“…The IFAT used in the present survey was performed with Spanish B. caballi strains, since it appears that they detect the presence of haemoparasite antibodies more successfully than the cELISA. Thus, Kuttler et al [59] and Prochno et al [76] confirmed that, due to regional differences, the use of antigens from autochthonous strains provides the best results.…”

“…Nevertheless, other authors showed the absence of an age-prevalence relationship [1, 3, 8, 10, 17, 23, 26, 36, 40, 46, 69, 75, 76, 80, 92, 94]. The present study pointed out that less than 1/4 of the foals and yearlings were seropositive for both parasites, with an increase in the percentage of infected horses until stabilisation at 11 and 14 years of age for T. equi and B. caballi, respectively, as Cantú-Martínez et al reported [23].…”

“…In Orlândia county, state of São Paulo (SP), southeast Brazil, 73.8% and 93.2% of the serum samples from donkeys were positive for T. equi and B. caballi, respectively. In the State of Paraná (PR), south Brazil, 61% of the animals were seropositive for T. equi in a study population of 400 horses (Prochno et al, 2014). In the State of Rio Grande do Sul (RS), Brazil, blood samples from 108 mares were collected in a premise located in the south of the state; 22% and 15% of these samples were positive for T. equi by Indirect Immunofluorescent Test (IFAT) and by nPCR, respectively (Nizoli et al, 2008).…”

“…Serological studies on B. caballi and T. equi have been conducted in the south, southeast and central-west regions of Brazil, which have revealed B. caballi prevalence rates varying from 18 to 90% (BARBOSA et al, 1995;HEUCHERT et al, 1999;HEIM et al, 2007;KERBER et al, 2009;VIEIRA et al, 2013;NOGUEIRA et al, 2017;BRAGA et al, 2017) and T. equi prevalence rates from 17 to 100% (TENTER & FRIEDHOFF, 1986;BARBOSA et al, 1995;RIBEIRO et al, 1999;HEUCHERT et al, 1999;XUAN et al, 2001;HEIM et al, 2007;GOLYNSKI et al, 2008;KERBER et al, 1999KERBER et al, , 2009BALDANI et al, 2010;SALVAGNI et al, 2010;VIEIRA et al, 2013;PROCHNO et al, 2014;VIEIRA et al, 2015VIEIRA et al, , 2018FERREIRA et al, 2016;GUIMARÃES et al, 2016;BRAGA et al, 2017;SCHEIN et al, 2018). However, such studies have rarely been carried out in northeastern Brazil.…”
