“…The occurrence of Theileria equi and Babesia caballi has been tied closely with the geographic distribution and seasonal activity of its biological vectors (Turaki et al, 2014;Davitkov et al, 2016). Similar to our findings, higher prevalence of Theileria equi compared to Babesia caballi has been reported in horses sampled in northern Nigeria (Ehizibolo et al, 2012), northeast Nigeria (Turaki et al, 2014), in horses sampled in four widely separated states of Nigeria (Mshelia et al, 2016), outside Nigeria: in Sudan (Salim et al, 2013), Mongolia (Munkhjargal et al, 2013), central Balkan (Serbia, Montenegro and Bosnia and Herzegovina) (Davitkov et al, 2016) and Spain (Cortés et al, 2017). The higher prevalence of Theileria equi compared to Babesia caballi can be attributed to the fact that horses infected with T. equi may remain lifelong carriers, whereas B. caballi is eliminated from the bloodstream, this making the transmission and infection of the former easier and higher compared to that of the later.…”

Haemoparasitism remains persisting as the major challenge to animal health and production causing the destruction of red blood cells resulting in anaemia, jaundice, anorexia, emaciation, reduced productivity, infertility and even death. provide information on the diversity of haemoparasites species affecting animals in Plateau State, North-central Nigeria. Blood samples collected 252 sheep; 393 goats; 129 dogs and 23 horses) wer haemoparasites. Babesia bigemina, Babesia bovis, Trypanosoma vivax, Anaplasma marginale, Theileria mutans and Theileria velifera (14.97%); 95% CI: 12.05-18.30 7.64) been the most prevalent. Anaplasma ovis was detected in both sheep and goats, although Babesia ovis and Babesia motasi goats respectively. Two species were detected each in dogs and horses with Theileria equi been more prevent in that a variety of haemoparasites species are found to infect domestic animals in Plateau State, North Central Nigeria. Considering the importance of domestic animals to national economy and the devastating effect of these haemoparasites, there is need for a rad appropriate and routine prophylactic treatments of animals, and regular vector (ticks and biting flies) control using efficacious acaricides and fly traps to arrest the menace.

Equine theileriosis, an apicomplexan debilitating tick-borne parasitic disease of horses has caused considerable havoc to equine production all over the world. There is a dearth of information on the molecular characteristic of the parasites, Theileria equi Laveran, 1901, in Nigeria. Thus, in this study microscopy techniques and PCR were used to detect the T. equi of horses in Ogun, Oyo and Lagos States of Nigeria. We also characterized the partial region of 18S ribosomal RNA gene by sequencing and sequences analysis. One hundred and two horses consisting of Argentine 34 (33.3 %), Sudanese 21 (20.6 %) and local breeds 47 (46.1 %) including 2 females and 100 males were randomly sampled from the Polo Clubs in Ibadan, Lagos and from privately owned horse stables in Abeokuta. Blood samples were collected from the jugular vein, thin smears were prepared and stained with a field stain. The DNA was extracted from the blood and a partial region of the 18S ribosomal RNA gene was amplified. The amplified products were sequenced unidirectionally and subjected to phylogenetic analysis with those sequences obtained from the Gen-Bank. Of the 102 horses tested, 12 (11.7 %) were positive for T. equi by microscopy which included 9 (19.1 %) local breeds, 2 (5.8 %) Argentine breed and 1 (4.8 %) Sudanese breed. In contrast, 7 (6.8 %) were positive by the PCR method; out of which 5 (10.6 %) of these samples were from the local breed of horses while the remaining 2 (5.8 %) were from the Argentine breed. The Packed Cell Volume (PCV) of the infected and non-infected horses did not show any significant (P < 0.05) difference. The sequences lengths obtained were 311 bp and they had 97.43—98.07 % homologies with available sequences in the GenBank. The phylogenetic analysis of the sequences suggested that the strain of T. equi detected in the study area formed a new genotype different from the established genotypes around the world. In conclusion, the prevalence of T. equi was very low in the study area and one strain of the parasite may be in circulation among the studied horses.

“…The epidemiological data on EP in Nigeria were based solely on microscopic observation [8][9][10]12,13] and in a few cases, serology using competitive-inhibition enzyme-linked immunosorbent assay (cELISA) [11].

Equine piroplasmosis (EP) is a tick-borne disease of equids, caused by the two haemoprotozoal parasites: Theileria equi and Babesia caballi. Nigeria constitutes a major crossroads of animal transport in West Africa and may serve as a factor in EP dissemination in the region. The study aim was to characterize EP parasites in donkeys and horses in northern Nigeria using a molecular approach. Blood was collected from 57 donkeys and 47 horses. EP infection was detected and characterized by polymerase chain reaction (PCR). Twenty five donkeys (43.8%) were infected with T. equi, five (8.8%) with B. caballi, three (5.3%) with dual infections. Four horses (8.5%) were infected by T. equi and none by B. caballi. Four of the five known T. equi 18S rRNA genotypes (A, B, C and D) were identified. Theileria equi ema-1 and ema-2 genes were amplified in only 2 and 10 samples, respectively, showing no genetic variation. All B. caballi isolates were classified as rap-1 genotype A1. Twenty-two (42.3%) of the donkeys were positive for anti-T. equi antibodies and 29 (55.8%) were positive for anti-B. caballi antibodies, using immunofluorescence antibody test (IFAT). The study results demonstrate high genetic variation within T. equi parasites, suggesting that donkeys may be reservoirs of EP parasites in West Africa.
