“…Molecular taxonomy revealed the host specificity of piroplasmids to be lower than previously supposed (Moretti et al, 2010;Qablan et al, 2012). Although those were mainly the zoonotic species (Babesia EU1, Babesia microti and Babesia divergens) attracting the attention (Häselbarth et al, 2007;Gray et al, 2010), the role of dogs in life cycle of "non-canine" piroplasmids species can have epidemiological consequences.…”

“…Molecular diagnostic assays followed by sequencing allow the detection of piroplasmids, even during latent infections, as well as determination of genotypes (Qablan et al, 2013). During the last decade, several molecular studies illustrated lower host-specificity of piroplasmids (Fritz, 2010;Hamel et al, 2012;Qablan et al, 2012) and suggested possible transmissions between equines and dogs. So far, five T. equi and three B. caballi genotypes have been described, with more diversity reported within T. equi (Munkhjargal et al, 2013).…”

“…The accumulating identifications and descriptions of new Babesia species in a wide range of hosts encourage us to predict that its research will become a highly dynamic field in the next few years. The piroplasmids that have been reported to date from dromedary camels can be either specific to these hosts or may represent species identified in other host organisms, which have been transmitted to camels via shared ticks; one such example is Babesia caballi, which has been recently demonstrated to infect camels (19). Therefore, further studies using PCR-based identification of the infecting Babesia sp.…”

“…Among these reports, our recent study describes the clinical, parasitological, haematological, and biochemical findings induced by naturally occurring theileriosis in Camelus dromedaries (10). Theileria equi and Babesia caballi have also been identified by PCR in Jordanian dromedaries (19). The first report of Babesia-like infection in camels failed to provide any description of the parasite in the blood cells of the animals (5).…”

Clinical, haematological, and biochemical changes induced by naturally occurring babesiosis in dromedary camels were described. Of 258 dromedary camels studied, 34 camels suffered from fever, appetite loss, weakness, depression, and reluctant movement; abortion and/or infertility were also observed. Parasitological blood examinations were performed using Giemsastained blood smears. The clinically affected animals were diagnosed with babesiosis, with 13.17% overall morbidity. Camels that suffered from babesiosis were subjected to haematological and biochemical analyses and the affected group was compared with a control group containing 34 healthy camels. The affected animals showed a highly significant (P<0.001) reduction of the total red blood cell (RBC) count, haemoglobin (HGB) concentration, and mean corpuscular volume (MCV) as well as a highly significant reduction (P<0.01) of haematocrit (HCT) and a significant reduction of (P<0.05) mean corpuscular haemoglobin (MCH). Additional, highly significant increases (P<0.01) in white blood cell (WBC) count and plateletcrit (PCT) percentage were detected. However, other haematological parameters were not significantly altered. There was a very significant reduction (P<0.001) of the blood iron level and a very significant increase (P<0.001) in blood urea nitrogen (BUN) and lactate dehydrogenase (LDH) in the affected camels. Additionally, significant increases in total protein, albumin, γ-glutamyltransferase (GGT), aspartate aminotransferase (AST), and total bilirubin were observed in the affected camels. It was concluded that babesiosis highly affects the haematobiochemical parameters of dromedary camels, including the liver, kidney, and muscle functions. These results represent novel findings concerning natural babesiosis in camels.

“…Since it is a chronic disease, and the symptoms caused in camels are mild, few reports have been published on its prevalence in the world. Its prevalence rates in Saudi Arabia, Egypt, Jordan, and Iran are 38.73, 30.4, and 15.79%, respectively (7,8,9, and 10).…”

The breeding of camels in the world is growing expansionary due to increasing in consumption rate of its meat, milk and wool. Besides, The rise of profitability of this industry and importing of camels into the country through the South East borders make it important to recognize infectious diseases in this species. Theileriosis a fatal protozoan infection with worldwide distribution into the domestic animals. It has two important species, Theileria camelensis, and Theileria Dromedarii. Because of low reliability in the current visual detection of this diseases we designed this study to investigate the prevalence of camels Theileria in Zabol and Zahedan district.Blood of 310 tick infected camels were collected from the jugular vein during July 2014 to July 2005. DNA was extracted from a whole blood sample, and PCR determined the presence of the parasite.The results showed that none of the blood contains the DNA of Theileri Camelensis and Theileria Dromedarii This result suggests that this population of camels in the southeast of country is clean from the Theileri Camelensis and Theileria Dromedarii.
