“…Theileria species are tick‐transmitted protozoa that worldwide infect a variety of domestic and wild ruminants, including deer, such as Axis, Brown Brocket, Fallow, Marsh, Red, Roe, Sika, and Chinese Water deer . In the US, Theileria spp are reported in elk (Wapiti) and in Axis, Sika, White‐tailed, and Mule deer .…”

A 5-year-old male neutered reindeer (Rangifer tarandus tarandus) from Missouri was presented with a 3-week history of anorexia, respiratory distress, lethargy, and weight loss. Blood smear review revealed that a small percentage of RBCs contained small (1-2 μm in length) pleomorphic piroplasms (signet ring, rod- or pear-shaped, and elongate forms) with an eccentric magenta nucleus and basophilic cytoplasm. Nested PCR to specifically amplify a portion of the piroplasm small subunit ribosomal RNA (SSU rRNA) gene was performed on DNA extracted from an EDTA specimen of whole blood. Subsequent sequence analyses showed similarity between the reindeer hemoparasite and Theileria spp SSU rRNA gene sequences in the GenBank database, with highest similarity to those of a Theileria sp in a White-tailed deer from North Texas (AY735132, AY735133). The reindeer and North Texas Theileria sp are genetically distinct from, albeit closely related to, the White-tailed deer Theileria sp (subsequently referred to as T cervi). To the authors' knowledge, this is the first identification of Theileria of this genotype in a reindeer. Historically, T tarandirangiferis infection was found with associated mortality in reindeer in Russia, but reports predate molecular characterization. Hence, the relationship of T tarandirangiferis with either T cervi or this agent remains unknown. T cervi is not typically pathogenic in White-tailed deer in the US unless the animal is immune-compromised by stress or disease; however, mortality from T cervi infection in reindeer has been reported.

“…Many molecular methods, such as PCR, Reverse line blot hybridization (RLB) and polymerase chain reactionrestriction fragment length polymorphism were used to differentiate T. lestiquardi and T. ovis Aktas et al 2006;Altay et al 2007;Heidarpour Bami et al 2009). As a result, T. ovis was reported using these methods in many countries, such as eastern Turkey , Northern Spain (Nagore et al 2004), South Korea (Han et al 2009), Iran (Hashemi-Fesharaki 1997Heidarpour Bami et al 2009), Ghana (Bell-Sakyi et al 2004) and so on. Meanwhile, the survey demonstrated a high prevalence of subclinical infections in these relative areas.…”

The experimental transmission of a newly isolated Theileria ovis is described. Hyalomma anatolicum anatolicum nymphs developed from larvae engorged on sheep infected with T. ovis were able to transmit the T. ovis to splenectomized sheep. Meanwhile, H. anatolicum anatolicum adults developed from nymphs engorged on sheep infected with T. ovis were also able to transmit T. ovis to splenectomized sheep. These experiments suggested that T. ovis could be transmitted by a H. anatolicum anatolicum, and the mode of transmission is from stage to stage.

“…This includes genotypes for T. sp. OT3 (Nagore et al., 2004; Tian et al., 2014), T. capreoli (García-Sanmartín et al., 2007; Yang et al., 2014b), T. cervi (Chae et al., 1998, 1999a), giraffe Theileria (Oosthuizen et al., 2009; Githaka et al., 2013), waterbuck Theileria (Githaka et al., 2014), white-tailed deer Theileria , water deer Theileria (Han et al., 2009). Many of these genotypes have been identified in multiple antelope species, making designation according to host specificity difficult.…”

HighlightsSerological and molecular assays exist for most economic important Theileria species.Molecular assays are constantly being improved with regard to sensitivity and specificity.The concept of what constitute a Theileria species impacts on accurate diagnostics.Analytical specificity of molecular assays are >800 000 parasites/L blood.Parasitemia ranges may determine practical limits of detection.
