Treatment of pregnant mares to prevent abortions due to equine piroplasmosis is a novel idea practised empirically at some Thoroughbred studs in South Africa. This paper presents the results of an investigation to ascertain whether imidocarb dipropionate crosses the equine placenta. Three pregnant mares were injected intramuscularly with imidocarb and their foetuses were mechanically aborted at varying time intervals thereafter. Imidocarb was found in foetal blood at a level similar to that in the dam's blood, suggesting that imidocarb administered to the dam would be available for anti-parasitic activity in the foetal circulation. Uncertainty concerning the time of treatment to achieve the desired effect currently makes this a questionable exercise.

ABSTRACT Antimicrobial treatment of persistent infection to eliminate transmission risk represents a specific challenge requiring compelling evidence of complete pathogen clearance. The limited repertoire of antimicrobial agents targeted at protozoal parasites magnifies this challenge. Using Babesia caballi as both a model and a specific apicomplexan pathogen for which evidence of the elimination of transmission risk is required for international animal movement, we tested whether a high-dose regimen of imidocarb dipropionate cleared infection from persistently infected asymptomatic horses and/or eliminated transmission risk. Clearance with elimination of transmission risk was supported by the following four specific lines of evidence: (i) inability to detect parasites by quantitative PCR and nested PCR amplification, (ii) conversion from seropositive to seronegative status, (iii) inability to transmit infection by direct inoculation of blood into susceptible recipient horses, and (iv) inability to transmit infection by ticks acquisition fed on the treated horses and subsequently transmission fed on susceptible horses. In contrast, untreated horses remained infected and capable of transmitting B. caballi using the same criteria. These findings establish that imidocarb dipropionate treatment clears B. caballi infection with confirmation of lack of transmission risk either by direct blood transfer or a high tick burden. Importantly, the treated horses revert to seronegative status according to the international standard for serologic testing and would be permitted to move between countries where the pathogen is endemic and countries that are free of the pathogen.

Equine piroplasmosis (EP) has historically been of minor concern to UK equine practitioners, primarily due to a lack of competent tick vectors. However, increased detection of EP tick vector species in the UK has been reported recently. EP screening is not currently required for equine importation, and when combined with recent relaxations in movement regulations, there is an increased risk regarding disease incursion and establishment into the UK. This study evaluated the prevalence of EP by both serology and PCR among 1242 UK equine samples submitted for EP screening between February and December 2016 to the Animal and Plant Health Agency and the Animal Health Trust. Where information was available, 81.5 per cent of submissions were for the purpose of UK export testing, and less than 0.1 per cent for UK importation. Serological prevalence of EP was 8.0 per cent, and parasite DNA was found in 0.8 per cent of samples. A subsequent analysis of PCR sensitivity in archived clinical samples indicated that the proportion of PCR-positive animals is likely to be considerably higher. The authors conclude that the current threat imposed by UK carrier horses is not adequately monitored and further measures are required to improve national biosecurity and prevent endemic disease.

Canine hepatozoonosis caused by Hepatozoon canis is an emerging disease in Europe. Clinical pictures vary from subclinical to life-threatening and non-specific clinical signs are predominantly reported. A 2-month-old female puppy originating from Southern Italy was adopted and moved to Northern Italy. Then, the dog was brought to a local veterinary practice for gastrointestinal signs, migrating lameness and pruritic dermatitis, and then tested positive for Hepatozoon spp. gamonts at the blood smear. After treatment with imidocarb dipropionate and doxycycline, the dog showed an initial clinical improvement. However, gastrointestinal signs recurred, and diffuse superficial pyoderma appeared on the thoracolumbar region, along with fever, lethargy, and weight loss. Eight months from the first onset of clinical signs, the dog was referred to a veterinary clinic and subjected to complete blood count, urine and fecal analysis, along with abdominal ultrasonography, whole-body CT and gastroduodenal endoscopy. Skin biopsies and blood samples were subjected to a PCR-coupled sequencing protocol, which scored both positive for H. canis. Alterations were consistent with a pre-existing cholangiohepatitis and multiple acquired extrahepatic shunts secondary to portal hypertension. The dog was euthanatized due to a clinical worsening two months later. The potential role of H. canis in the systemic disease observed, clinic-pathological findings and epizootiological implications are discussed.

This study was designed to detect equine piroplasmosis using the molecular technique in Al-Najaf province during the season that showed an increment in tick activities. Blood samples were collected from 110 horses with more than two signs of piroplasmosis. After DNA extraction, the product was examined by a polymerase chain reaction to amplify 18SrRNA. The results showed that the overall percentage of equine theileriosis was 38.18%. According to gender, the percentage of infection was 43.48% and 29.27% in females and males, respectively. Significant variations appeared between infected horses according to age, and the percentage of infection was 50% and 35.22% in less than 2 years and more than 2 years age, respectively. Moreover, the percentage of infection was 62.5% and 19.35% in animals with and without acariasis, respectively. Significant variations were also seen in equine theileriosis according to geographical areas, and the higher percentage was reported in Hera district (60.87%), while the lowest percentage was in the center of Al-Najaf (21.43%). This difference may be due to different distribution of vector of disease (tick), which may be the availability of the suitable weather that helped in the multiplication of the intermediate vectors. In conclusion, this study proved the variations in the occurrences of equine piroplasmosis according to gender, age, and geographical areas.

Background: The clinical study was designed to evaluate the haemato-biochemical changes in sheep affected with babesiosis and therapeutic regimes of various drugs used against babesiosis. Methods: A total of 24 clinically affected sheep with 6 animals in each group were selected for the haemato-biochemical and therapeutic study. The diagnosis was based on clinical manifestations, microscopic examination of blood smears and molecular confirmation of Babesia by PCR technique. For therapeutic study Group I, II, III and IV were treated with imidocarb dipropionate, imidocarb dipropionate+oxytetracycline, diminazene aceturate and diminazene aceturate+oxytetracycline, respectively. Result: The clinical signs recorded were high fever, pale mucous membranes, presence of ticks, inappetence, coffee-coloured urine and diarrhoea. The vectors identified were Haemaphysalis ticks. Hb, PCV, TEC, total protein, albumin, calcium, phosphorus and blood glucose were significantly (P less than 0.05) lower in the diseased group as compared to healthy animals while TLC, globulin and iron levels were significantly (P less than 0.05) higher compared to the healthy control group. The study revealed that the combination of imidocarb dipropionate and oxytetracycline was highly effective for ovine babesiosis.
