“…Previous studies on donkeys have reported a wide range in the value of (sero)prevalence, this particular study was on the higher side of the range reported. Reported T. equi true (sero)prevalence in donkeys range from approximately 2 to 85% (Turnbull et al, 2002;Chahan et al, 2006;Acici et al, 2008;Machado et al, 2012;Garcia-Bocanegra et al, 2013;Gizachew et al, 2013;Salim et al, 2013) and was similar to the work of Hawkins et al (2015) who found a prevalence of 72% (95% CI: 60.4-81.0%) using PCR. Scrutiny of prevalence values from previous studies is, however, limited due to their unique study designs and the effect of external factors such as husbandry (Kouam et al, 2010a;Garcia-Bocanegra et al, 2013).…”

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.

Babesia is one of the more common pathogens of freeliving animals worldwide, can contribute to wildlife disease complexes (Munson et al 2008), and is gaining increasing attention as an emerging tick-borne zoonotic agent in humans (Hunfeld and Lambert 2002;Acici et al 2008;Sigg et al 2010).…”

ABSTRACT:The role of equine piroplasmosis as a factor in the population decline of the Grevy's zebra is not known. We determined the prevalence of Babesia caballi and Theileria equi in cograzing Grevy's zebras (Equus grevyi) and donkeys (Equus africanus asinus) in northern Kenya and identified the associated tick vectors. Blood samples were taken from 71 donkeys and 16 Grevy's zebras from March to May 2011. A nested PCR reaction using 18s ribosomal (r)RNA primers on 87 blood spots showed 72% (51/71; 95% confidence interval [CI] 60.4-81.0%) of donkeys and 100% (16/16; 95% CI, 77.3-100%) of Grevy's zebras were T. equi positive. No samples were positive for B. caballi. Sequence comparison using the National Center for Biotechnology Information's basic local alignment search tool identified homologous 18s rRNA sequences with a global geographic spread. The T. equi-derived sequences were evaluated using Bayesian approaches with independent Metropolis-coupled Markov chain Monte Carlo runs. The sequences clustered with those found in Sudan, Croatia, Mongolia, and the US, with statistical support greater than 80% for the two main clades. Hyalomma tick species were found on both donkeys and Grevy's zebras, whereas Rhipicephalus pulchellus was found exclusively on Grevy's zebras and Hyalomma marginatum rupfipes on donkeys. The prevalence of T. equi was 100% in Grevy's zebras and 72% in donkeys with common tick vectors identified. Our results suggest that donkeys and Grevy's zebras can be asymptomatic carriers and that piroplasmosis is endemic in the study area.

“…According to the studies based on microscopic diagnosis, the prevalence rate of equine babesiosis is varying between 0 to 58.18% (Inci 1997, Akkan et al 2003, Kurt 2005, Balkaya and Erdogmus 2006. The serological studies performed by ELISA, IFAT and complement fixation test (CFT) showed that the occurrence of T. equi varied between 12.8 and 64.5% and B. caballi between 0 and 34.6% (Akkan et al 2003, Kurt 2005, Balkaya and Erdogmus 2006, Oncel et al 2007, Acici et al 2008, Sevinc et al 2008, Karatepe et al 2009, Sari et al 2010. The prevalence rates of T. equi and B. caballi in the show/sport horses have been found 7% and 3% by PCR, respectively (Guclu and Karaer 2007).…”

“…Very little information is available on the tick vectors of equine babesiosis in Turkey. According to the limited number of study, the tick species H. marginatum, H. detritum, R. bursa and R. turanicus were found on the horses infected with the equine Babesia species (Inci 1997, Akkan et al 2003, Acici et al 2008. In terms of epidemiology, most of these reports are not enough to elucidate the tick vector species of the disease.…”
