Significant Economic Loss

Equine piroplasmosis (EP) is a tick-borne disease caused by Babesia caballi and Theileria equi, which causes a significant economic loss. The aim of this study was to determine the disease-related changes of serum trace elements that play an important role in the immune system. Our study was conducted on 20 horses with piroplasmosis and 20 healthy horses. It was performed to evaluate some of the serum trace element levels (chromium (Cr), copper (Cu), iron (Fe), magnesium (Mg) manganese (Mn), selenium (Se), zinc (Zn), arsenic (As), boron (B), and nickel (Ni)) in equine piroplasmosis. The elements were analyzed in serum using ICP-OES. Infected horses had significantly higher serum Mg and Mn levels. In conclusion, changes of serum trace elements in infected horses can provide valuable information about pathophysiological aspects and they are also good indicators for diagnosis, prognosis and treatment evaluation. Much more scientific research is required to evaluate the trace elements related to equine piroplasmosis.

Tick Borne Disease

Equine piroplasmosis (EP), caused by the hemoparasites Theileria equi, Theileria haneyi, and Babesia caballi, is an important tick-borne disease of equines that is prevalent in most parts of the world. Infection may affect animal welfare and has economic impacts related to limitations in horse transport between endemic and non-endemic regions, reduced performance of sport horses and treatment costs. Here, we analyzed the epidemiological, serological, and molecular diagnostic data published in the last 20 years, and all DNA sequences submitted to GenBank database, to describe the current global prevalence of these parasites. We demonstrate that EP is endemic in most parts of the world, and that it is spreading into more temperate climates. We emphasize the importance of using DNA sequencing and genotyping to monitor the spread of parasites, and point to the necessity of further studies to improve genotypic characterization of newly recognized parasite species and strains, and their linkage to virulence.

Equine Piroplasmosis (EP) is a tick-borne disease caused by apicomplexan protozoan parasites, Babesia caballi and Theileria equi. The disease is responsible for serious economic losses to the equine industry. It principally affects donkeys, horses, mules, and zebra but DNA of the parasites has also been detected in dogs and camels raising doubt about their host specificity. The disease is endemic in tropical and temperate regions of the world where the competent tick vectors are prevalent. Infected equids remain carrier for life with T. equi infection, whilst, infection with B. caballi is cleared within a few years. This review focuses on all aspects of the disease from the historical overview, biology of the parasite, epidemiology of the disease (specifically highlighting other non-equine hosts, such as dogs and camels), vector, clinical manifestations, risk factors, immunology, genetic diversity, diagnosis, treatment, and prevention.

Recently, Nutrition Support Teams (NSTs) has been spreading throughout Japan. Nutritional assessment is important as an initial step among NST activities, since the patients can be identified based on this assessment whether they needs supports by NST or not. Serum trace element is one of the most useful and convenient nutritional indices. The aim of this study is to analyze the relationships between serum trace element values and clinical backgrounds in NST patients by data mining. The subjects of this study consisted of 29 NST patients who were admitted to our hospital between January 2005 and October 2006. Serum trace elements in patients were analyzed by PIXE method. The data were analyzed by a data mining software, i.e. "ICONS Miner" (Koden Industry Co., Ltd.). The significant "if-then rules" were extracted from the decision trees. The target variable of the decision trees is whether nutritional conditions of the patients are improved or not (Yes/No). The explanatory variables of the decision trees are the values in serum trace elements (Fe, Cu, Zn, Se, Mn) and TTR (transthyretin). The analyses demonstrated that the first node of the decision tree was Zn. Therefore, serum Zn value might be the most significant factor among these trace elements in estimating the improvement of nutritional conditions of the patients. In the decision, the second branch was the Fe value, and the Cu the third. The following significant "If-then rules" were extracted from the decision trees. If-then rule 1: If serum Zn value >758.6 µg/l, then improvement of nutritional condition = Y. (1.00 = 9/9) If-then rule 2: If serum Zn value ≤758.6 µg/l and Fe ≤653.2 µg/l and Cu ≤682.5 µg/l, then improvement of nutritional condition = Y. (1.00 = 5/5) If-then rule 3: If serum Zn value ≤758.6 µg/l and Fe ≤653.2 µg/l and Cu >682.5 µg/l and Se >119.8 µg/l, then improvement of nutritional condition = Y. (1.00 = 3/3) In conclusion, data mining analysis of serum trace elements was found to be an effective method in assessing the nutritional conditions in NST patients.

Abstract Equine piroplasmosis (EP) is an ixodid tick-borne disease caused by Theileria equi and/or Babesia caballi that can lead to severe health issues and economic losses among equine population. This study aimed to determine the prevalence of T. equi and B. caballi among Egyptian equines based on microscopy and conventional PCR. Also, to determine the effect of season, age, and sex of on their prevalence and determining the difference in sensitivity between microscopy and conventional PCR in the diagnosis of EP. This study was carried out on 432 blood samples randomly collected from 146 horses and 286 donkeys during a period from April 2016 to March 2018. Microscopic examination revealed that among horses, 13 (8.9%) and 4 (2.7%) were infected by T. equi and B. caballi respectively. While among donkeys, 22 (7.7%), 16 (5.6%) respectively. While mixed infections were detected in 4 (1.4%) donkeys. There was a statistically nonsignificant relation between prevalence of infection and season and sex of equines but the highest prevalence was recorded in age group less than 5 years old. By conventional PCR, among 64 horses, 15 (23.4%) and 8 (12.5%) were infected by T. equi and B. caballi, respectively. While among 76 donkeys, 36 (47.4%), 16 (21.1%), and 5 (6.6%) were infected by T. equi, B. caballi, and mixed infection, respectively. Our finding proved the existence of T. equi and B. caballi among equines.

BackgroundEquine piroplasmosis (EP) is a notifiable disease in Ireland and a significant concern to domestic and international equine industries. Information regarding EP presence in Ireland is currently limited. This retrospective surveillance study describes a serological and molecular analysis of blood samples submitted to the Irish Equine Centre for EP testing between January 2013 and April 2016.MethodsFollowing serological testing, seropositive samples were screened using a PCR targeting the 18S ribosomal RNA gene. Amplicon sequences were bioinformatically analysed to identify the parasite species and to assess genetic diversity.ResultsFrom 2099 screened equine blood samples, 2.5 per cent and 1 per cent were seropositive for Theileria equi and Babesia caballi, respectively. T equi DNA was detected in 9 per cent of the seropositive samples while B caballi DNA was not detected in any sample. The T equi DNA sequences displayed no genetic diversity at this locus, in contrast to samples from the UK and from endemic areas.ConclusionDetection of EP-seropositive and parasitaemic horses in Ireland indicates a clear and present health risk to the equine population. It is recommended that owners adopt appropriate biosecurity measures and that clinicians are mindful of this disease as a differential diagnosis.

Abstract Equine piroplasmosis, an economically important disease in horses, has so far not been reported in Pernambuco state, Brazil. This study aimed to evaluate the seroprevalence of anti-Babesia caballi and anti-Theileria equi antibodies based on the detection of these agents in equine blood and in ticks on horses in the municipality of Petrolina, Pernambuco, northeastern Brazil. Blood samples were drawn from 393 horses and sera were examined by ELISA. The presence of tick infestations was evaluated, and 101 ticks were subjected to DNA amplification for the detection of Babesia spp. by polymerase chain reaction (PCR). No parasites were detected in the blood smears. Anti-B. caballi and anti-T. equi antibodies were found in 27.2% (107/393) and 34.8% (137/393) horses, respectively. Infestation by Dermacentor nitens was detected in 4.3% (17/393) of the horses. There was no DNA amplification of the agents in ticks. The risk factors for the presence of anti-T. equi antibodies (P < 0.05) were: purebred (P < 0.001), animals older than 156 months (P = 0.014), and the presence of ticks (P = 0.001). No risk factors for B. caballi were identified. This study confirmed the circulation of agents of equine piroplasmosis in the municipality of Petrolina, state of Pernambuco, Brazil.

Equine Piroplasmosis

Equine Piroplasmosis (EP) is a tick-borne disease caused by Theileria equi and Babesia caballi of the phylum Apicomplexa. In this study, 102 blood samples were randomly collected from the horses in Mus province of Turkey. PCR analysis, gene sequences, and phylogenetic analyses were carried out for detecting the presence and genotypic characteristics of species that cause piroplasmosis. Four (3.9%) of the 102 horses that were examined were found to be positive for T. equi, while B. caballi was not detected. Theileria equi isolates that were detected in the sequence analyses were found to be 100% identical to the isolates that were isolated from the horses in Turkey, the United States, and South Africa as well. In the phylogenetic analysis, all of the isolates were found to cluster with T. equi sequences in the genotype A. This study, in which we revealed intraspecies sequence heterogeneity of the parasite using the 18S rRNA gene region, provides important epidemiological data for equine piroplasmosis. However, we think that determining the characterization of genotypes that are common in different parts of our country is extremely important in terms of developing new diagnostic tools and vaccines.
