  • A 11-year-old neutered male Maltese dog was vaccinated with a rabies vaccine (Rabisin®, Boehringer Ingelheim International GmbH, Germany) subcutaneously at a local animal hospital. One hour after vaccination, purpura with edema was observed at the injection site and severe thrombocytopenia (0 K/μL) was noted on a complete blood count (CBC). No specific findings were found in serum chemistry, electrolyte, blood gas analysis, and coagulation tests. The patient was hospitalized and administered antihemorrhagic agents (vitamin K, desmopressin), antihistamines (chlorpheniramine) and corticosteroids (methylprednisolone sodium succinate). On a repeat CBC, mild anemia had developed, thrombocytopenia was still noted, and autoagglutination was observed on a saline agglutination test (SAT). A polymerase chain reaction panel for infectious agents (e.g., Babesia spp.) was negative. The diagnosis was secondary immune-mediated thrombocytopenia (IMT) with immune-mediated hemolytic anemia (IMHA) associated with vaccination. Therefore, the immunosuppressants (prednisolone, and mycophenolate mofetil) were administered. Six days after drug administration, new lesion was not observed, and the previous lesions were significantly improved. It gradually improved and 4 weeks after hematocrit and platelet recovered to normal levels. It was maintained for 6 months without recurrence of related symptoms. Based on patient's history and test results, the patient was diagnosed with Evans' syndrome associated with rabies vaccine.

  • Some small mammals occur as household pests and harbour a number of parasites that could be of public health importance. This study profiled the helminth and protozoan parasites in trapped small mammals within and around human dwelling places (houses) located across 4 major towns (Auchi, Benin, Ekpoma, and Uromi) and environs in Edo state, Nigeria. Six genera (Apodemus sp., Crocidura sp., Mastomys natalensis, Mus musculus, Rattus sp., and Sorex sp.) were identified from 502 trapped small mammals. Overall, M. musculus (71.9%) and Rattus rattus (20.1%) were the most frequently trapped. In total, on examination of blood, gastrointestinal contents, and brain tissues, 12 helminth taxa (Angiostrongylus sp., Aspicularis sp., Capillaria sp., Gongylonema sp., Heterakis spumosa, Hymenolepis diminuta, Hymenolepis nana, Mastophorus muris, Moniliformis moniliformis, Nippostrongylus brasiliensis, Strongyloides sp., Trichosomoides sp., and Trichuris sp.), and 6 protozoan parasites (Babesia sp., Trypanosoma lewisi, Plasmodium sp., Eimeria sp., Isospora sp., and Toxoplasma gondii) were isolated. Most prevalent helminths with relatively heavy mean intensity were Strongyloides sp. and Heterakis spumosa, while Plasmodium, Eimeria, and Isospora were the most prevalent protozoan parasites. Generally, intrinsic factors like sex and age had marginal influence on the rate and burden of infection in M. musculus and R. rattus. Although the infection rate and prevalence of zoonotic parasites were low, they were largely recovered in rodents from Ekpoma. This study elucidates the public health implication of the presence of zoonotic parasites in these small mammals.

  • A survey on the piroplasma infections for Canadian cows imparted from November 1968 to June 1969 to Kyungpuk, Korea was conducted by means of enumeration of erythrocytes and examination of Giemsa staining blood films from the cows and their calves. The results obtained were summarized as follows: 1. So-called small type piroplasma (Theileria) infections were suspected in almost all of imported cows and their calves during their first pasture season and mixed infections with so-called large type piroplasma (Babesia) or Eperythrozoon wenyoni were detected in some cows and calves. 2. Fever, anorexia, depression, marked decreased milk production, sever anemia and jundice were observed in the imported cows with havy infection of so-called small type piroplasma (Theileria). And the piroplasma infection was most important cause of deaths of imported cows. 3. Sever anemia, malnutrition and poor growth were observed in many calves from imported cows with havy infection of so-called small type piroplasma(Theileria). 4. Good results were obtained in treating cattle acutely ill with so-called small type piroplasmosis by injection of pamaquine but they may need scond injection 3 to 4 weeks after the first treatment for reapperence of the piroplasma in the erythrocytes.

  • This survey was conducted to observe the prevalence of blood parasites in slaughtered cattle included Korean native cattle, Charolias, Hereford, Aberdeenangus and Holstein breeds in the Western area of Kyeongnam. The results obtained are summarized as follows: 1. The prevalence of T sergenti was shown 71.8% as 395 heads of a total of 550 heads examined and from Jaunary to November the monthly prevalence of T sergenti was shown the range of 61.1% to 84% except 38.5% in December. The other blood parasites included Babesia and Anaplasma were not detected from the blood samples except Setaria spp microfilariae. 2. The distribution of parasitaemia levels of T sergenti in positive cattle was shown 93.9% in the range of 1~10/1000 rbc, 4.1% in 11~20, 1.3% in 21~30 and 0.8% above the range of 31. 3. The pervalence of T sergenti by breeds of slaughtered cattle was shown 71.2% in Korean native cattle, 72.7% in Charolias, 78.3% in Hereford and 81. 8% in others (Aberdeen-angus and Holstein) respectively. Also the parasitaemia levels in these cattle were shown higher levels in imported cattle included Charolias, Hereford, Aberdeen-angus and Holstein breeds comparing with Korean native cattle. 4. The prevalence of Setaria spp microfilariae in slaughtered cattle was shown 6.9% and by monthly prevalence of the parasite was shown higher in March, April and May compared with June, July, August and October. But in the winter season included January, February, November and December the parasite was not detected from the blood samples. 5. The distribution of parasitaemia levels of Setaria spp microfilariae per ml of blood was shown 65.8% in the range of 1~50, 13.2% in 51~100 and 10.5% in 101~200 and above the range of 201, respectively.

  • A 4-year-old spayed female, Yorkshire terrier dog with a history of petechial and ecchymotic hemorrhages on the face, trunk and hind limb was referred to Veterinary Medical Teaching Hospital, Cheju National University. The complete blood count revealed a marked thrombocytopenia ($96{\times}10^3/{\mu}l$). The biochemical profile showed only slightly increased glucose. The coagulation profile such as prothrombin time and activated partial thromboplastin time, was within the reference range. In Giemsa staining, there were no endoparasites like as Babesia spp. on the RBC. This case was diagnosed as a idiopathic thrombocytopenia in a Yorkshire terrier dog. She was treated with prednisone (1 mg/kg BW, IM q 12 h) and cephalosporin (10 mg/kg BW, IM, q 12 h). When rechecked on day 6, the platelet was within reference range ($507{\times}10^3/{\mu}l$) and also petechial and ecchymotic hemorrhages on the body were gradually improved without any complications. The dose of prednisone was decreased to 0.5 mg/kg BW, q 24 h. On day 17, we finished treatment because all the clinical signs, blood and serum chemistry were reference range and platelet count was dramatically increased.

  • Livestock husbandry is vital to economy of the Tarim Basin, Xinjiang Autonomous Region, China. However, there have been few surveys of the distribution of ixodid ticks (Acari: Ixodidae) and tick-borne pathogens affecting domestic animals at these locations. In this study, 3,916 adult ixodid ticks infesting domestic animals were collected from 23 sampling sites during 2012-2016. Ticks were identified to species based on morphology, and the identification was confirmed based on mitochondrial 16S and 12S rRNA sequences. Ten tick species belonging to 4 genera were identified, including Rhipicephalus turanicus, Hyalomma anatolicum, Rh. bursa, H. asiaticum asiaticum, and Rh. sanguineus. DNA sequences of Rickettsia spp. (spotted fever group) and Anaplasma spp. were detected in these ticks. Phylogenetic analyses revealed possible existence of undescribed Babesia spp. and Borrelia spp. This study illustrates potential threat to domestic animals and humans from tick-borne pathogens.

  • Ticks are the vectors of various pathogens, threatening human health and animal production across the globe. Here, for the first time we detected Ricketssia spp., Borrelia spp. and protozoan in ticks from Poyang Lake region in Jiangxi Province of eastern China. In 3 habitat categories and on 12 host species, 311 ticks from 11 species were collected. Haemaphysalis longicornis was the predominant species, accounting for 55.63%, followed by Rhipicephalus microplus, Haemaphysalis flava and Ixodes granulatus. Of the collected ticks, 7.07% were positive for tick-borne pathogens, and H. longicornis and H. flava were found to be co-infected with Ricketssia spp. and protozoan. H. flava was the most detected positive for tick-borne pathogens, whereas H. longicornis had the lowest infection rate, and the difference in infection rates between tick species was significant (${\chi}^2=61.24$, P<0.001). Furthermore, adult ticks demonstrated remarkably greater infection rate than immature ticks (${\chi}^2=10.12$, P=0.018), meanwhile ticks on Erinaceidae showed significantly higher positivity than ticks collected on other host species (${\chi}^2=108.44$, P<0.001). Genetic fragment sequencing and analyses showed at least 4 pathogen species presence in ticks, namely Borrelia yangtzensis, Rickettsia slovaca or Rickettsia raoultii related genospecies, Babesia vogeli and Hepatozoon canis or Hepatozoon felis related genospecies. The finding indicates that the abundant ticks can carry diverse pathogens in Poyang Lake region, and pathogen infection is highly related to species, vertebrate hosts and life stages of ticks.

  • Canine vector-borne diseases (CVBDs) are transmitted by different groups of hematophagous arthropod vectors that are distributed worldwide and can cause significant health problems for dogs. The aim of this study was to investigate and compare the prevalence of selected CVBD pathogens in rural outdoor dogs based on prevention status. Between June 2017 and February 2019, blood samples were collected from 343 clinically healthy rural dogs composing two different groups: systematically managed dogs (SMD; n=92) and personally managed dogs (PMD; n=251). Vaccination and preventive medications were applied strictly following the programmed schedule for the SMD group; in contrast, in the PMD group, they were applied only when requested by the dog owners. Serological and molecular assessments showed that significantly more dogs in the PMD group were infected with B. gibsoni (P<0.001) and D. immitis (P=0.001) than those in the SMD group. These findings suggest that the regular use of preventive medications and environmental controlling efforts contribute to reducing the prevalence of CVBD pathogen infections. In addition, dogs infected with certain kinds of CVBD pathogens could remain asymptomatic, suggesting that continuous monitoring and periodic preventive treatment should be conducted even for clinically healthy dogs.

  • Equine piroplasmosis (EP) is caused by Babesia caballi and Theileria equi infection. We investigated antigen and antibody of EP in horses in the Republic of Korea during 2016-2017. Antigen and antibody of T. equi was detected 0.06% (1/1,650). Phylogenetic analysis of 18S rRNA revealed that the T. equi was highly homologous with the strains from China, Mongolia, and Spain. Two Theileria spp. were also detected and highly homologous with T. buffeli, T. luwenshuni, and T. orientalis.
