“…This was consistent with observations by Shkap, et al (1998), Acici, et al (2008, Karatepe, et al (2009), Grandi, et al (2011), Mujica, et al (2011), Cantu-Martinez, et al (2012), Steinman, et al (2012 and Farkas, et al (2013). Reports by Asgarali, et al (2007), Ruegg, et al (2007) and (2008), Kouam, et al (2010a) and Garcia-Bocanegra, et al (2013) have, however, illustrated statistically significant cumulation of infection with progress in age.…”

Equine piroplasmosis is one of the most significant tick-borne disease of equids. The prevalence of this disease in donkeys of semi-arid Kenya remains largely unexplored. The primary objective of this study was to demonstrate the extent to which donkeys in Nuu division, Kenya have been exposed to the haemoprotozoans Babesia caballi and Theileria equi, the causative agents of equine piroplasmosis. The study also assessed the effect of age and sex on seroprevalence. A stratified sampling approach was used and three hundred and fourteen donkeys were sampled across nine sub-locations in Nuu division, Mwingi district. Serodiagnosis was via competitive inhibition enzyme linked immunosorbent assays (cELISA). The seroprevalence of T. equi was 81.2% (95% CI: 76.4-85.4). There was no significant difference in sub-location seropositivity, gender seropositivity or age related seropositivity. Antibodies against B. caballi were not detected (95% CI: 0-1.2). Findings from this study suggest that T. equi infection is endemic in Nuu division, Mwingi where it exists in a state of endemic stability. Existence of the infection should be communicated to animal health practitioners and donkey owning communities in the area.

“…Furthermore, treatments do not completely eliminate T. equi from the animals [18, 28]. The situation reported by other authors is different since B. caballi is more prevalent than T. equi , which has been related to the presence of the appropriate tick vectors for the transmission of B. caballi [69]. …”

“…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].…”

Seroprevalence of Theileria equi and Babesia caballi in horses in Spain

Equine piroplasmoses are enzootic parasitic diseases distributed worldwide with high incidence in tropical and subtropical regions. In Spain, there is insufficient epidemiological data about equine piroplasmoses. The main aim of the present study was therefore to estimate the prevalence of Theileria equi and Babesia caballi in five regions and obtain information about the risk factors. This study was conducted in the central and south-western regions of Spain, using indirect fluorescence antibody testing (IFAT) in 3,100 sera samples from apparently healthy horses of different ages, breeds, coat colours, genders and geographical locations. The overall seroprevalence was 52%, consisting of 44% seropositive for T. equi and 21% for B. caballi. There was a significant association between age (p < 0.0001), breed (p < 0.004), geographical location (p < 0.0001) and the seroprevalence, but neither the coat colour nor the gender was significantly associated with prevalence. In addition, it was proved that most of the geographic areas showed a moderate to high prevalence. The statistical κ value was used to compare the results obtained by the IFAT and the competitive enzyme-linked immunosorbent assay (cELISA) utilised to test some samples (n = 108) and showed a higher concordance for T. equi (κ = 0.68) than for B. caballi (κ = 0.22). Consequently, this revealed the importance of developing an appropriate technique to detect each haemoparasite.

“…Moreover, thoroughbred horses receive balanced meals and proper veterinary care and thus are at lesser risk of tick infestation. A tenuous relation association of the disease prevalence was observed with the age of host animals by both molecular and serological methods (Shkap et al 1998;Karatepe et al 2009;Mujica et al 2011;Steinmana et al 2012); utmost care is taken for equids in Punjab state, as they (only horses) are primarily utilized for breeding and recreational purposes. A contrary scenario has been reported by Rüegg et al (2007) and Kouam et al (2010).…”

A cross-sectional study was conducted in Submountain undulating, Undulating plain, Western and Western plain agro-climatic zones of Punjab province, India, to determine the prevalence, agreement between diagnostic tests and associated related risk factors of Theileria equi and Babesia caballi infection in equids (horses, donkey, mules). An overall prevalence of 14.14 and 0.0% of T. equi and B. caballi was recorded by multiplex polymerase chain reaction targeting 18S ribosomal RNA (rRNA) for both the parasites and 75 and 1.11% by competitive enzyme-linked immunosorbent assay in a representative sample of 180 animals. Only two animals with positive antibody titre from B. caballi and none with PCR indicated T. equi as the predominant haemoprotozoan responsible for equine piroplasmosis in the study area. Among the PCR-positive animals, presence of tick vectors in farm vicinity was the most influential associated with T. equi infection (P = 0.002; odds ratio (OR) 9.30; 95% confidence interval (CI) = 3.32-27.10). For animals with higher anti-T. equi antibody titres, strong association of sero-prevalence for T. equi was recorded with age, sex, usage, tick infestation and deworming/vaccination status of host animals and farm management strategies. The study has demonstrated the possible absence of B. caballi in both conducive and non-conducive areas of Punjab and demonstrated T. equi as the potential agent of equine piroplasmosis in Punjab.
