Prevalence of intestinal parasites in dogs from public shelters in Serbia

Data on endoparasitic infections in dogs from dog shelters in Southeastern Europe are limited; thus, this study aimed to add to the existing knowledge on this topic by reporting on the prevalence of intestinal parasites in dogs from public dog shelters in the Republic of Serbia. In 2017 and 2018, individual and pooled fecal samples, were collected from 1267 dogs from six shelters. All samples were qualitatively examined for parasites using flotation tests. Seven taxa of intestinal parasites were identified: Cystoisospora spp., ascarids: Toxocara canis and Toxascaris leonina, hookworms, Trichuris vulpis, taeniids and Dipylidium caninum. The overall prevalence of intestinal parasites was 58. 3 % (78. 1 % in young dogs and 53.1 % in adult dogs). The parasites detected in both young (<1 year old) and adult dogs (>1 year old) were Cystoisospora spp. (20 % and 4.9 %), T. canis (33.5 % and 14.7 %), T. leonina (7.7 % and 2.3 %), and hookworms (16.9 % and 15 %), respectively. However, T. vulpis (9.6 %), taeniids (1.3 %), and D. caninum (5.4 %) were detected only in adult dogs. In the Belgrade shelter, young dogs had a higher prevalence of endoparasitic infections (18.9 %, 49/260) than adult dogs (14.8 %, 149/1007). In the Subotica, Jagodina and Niš shelters, young dogs had significantly higher (p < 0.001 and p < 0.05, respectively) prevalence of endoparasitic infections (10 %, 12.3 % and 14.6 %) than adult dogs (5.3 %, 8 % and 7.2 %). These results will be useful for establishing health care programs in dog shelters and implementing effective strategies for the control of intestinal parasites.

新型莫西菌素浇泼剂对羊蜱蝇和消化道线虫驱虫药效评价

试验旨在通过新型莫西菌素（moxidectin,MOX）浇泼剂对羊的驱虫试验,评价MOX浇泼剂对羊蜱蝇和消化道线虫的临床药效。将150只阿勒泰羊经产母羊随机分为6组,每组25只,分别为不用药对照组、螨净药浴组、MOX注射组和MOX低（0.05 mL/（kg·BW））、中（0.1 mL/（kg·BW））和高（0.2 mL/（kg·BW））剂量浇泼组,试验期为1周。试验第1天按前述分组中方法和剂量驱虫1次。观察受试动物临床表现,测定给药前1天和给药后第7天体温、脉搏和呼吸（TPR）,血液生理、生化和尿常规指标;测定羊蜱蝇减虫率、治愈率。采取粪样测定消化道线虫每克粪中虫卵个数（EPG）减少率及转阴率。结果显示,与不用药对照组相比,给药后第7天各驱虫组TPR、血液生理、生化及尿常规指标均无显著差异（P>0.05）。螨净药浴组羊蜱蝇减虫率为43.7%,而MOX注射组及MOX低、中、高剂量浇泼组均为100%。螨净药浴组治愈率为13.0%,而MOX注射组及MOX低、中、高剂量浇泼组均为100%;与不用药对照组相比,螨净药浴组消化道线虫卵减少率为0,而MOX注射组及MOX低、中、高剂量浇泼组分别为91.6%、93.1%、94.9%和97.8%。螨净药浴组虫卵转阴率为0,而MOX注射组及MOX低、中、高剂量浇泼组分别为77.0%、69.2%、69.2%和84.6%。本试验结果表明,新型MOX浇泼剂对体外寄生虫和消化道线虫均有显著疗效,且优于螨净药浴,与MOX注射剂等效。实践应用中最适MOX浇泼剂量推荐为0.05 mL/（kg·BW）（即0.25 mg/（kg·BW））。     

Blood, Bull Terriers and Babesiosis: further evidence for direct transmission of Babesia gibsoni in dogs

This study reports on the epidemiology of Babesia gibsoni in American Pit Bull Terriers living in a region of western Victoria in southern Australia. Both American Pit Bull Terriers (n = 100) and other dog breeds (n = 51) were screened for B gibsoni using immunofluorescent antibody testing (IFAT) and/or polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). A questionnaire was also completed by each dog owner, ascertaining the husbandry and habits of the dogs sampled. Fourteen dogs were positive for B gibsoni using IFAT and/or PCR-RFLP and all were American Pit Bull Terriers. Dogs that were male and/or had been bitten by or were biters of other American Pit Bull Terriers were more likely to be B gibsoni positive, thus suggesting that blood-to-blood transmission contributes to the spread of this disease between dogs.

Plants as de-worming agents of livestock in the Nordic countries: historical perspective, popular beliefs and prospects for the future.

Preparations derived from plants were the original therapeutic interventions used by man to control diseases (including parasites), both within humans and livestock. Development of herbal products depended upon local botanical flora with the result that different remedies tended to develop in different parts of the world. Nevertheless, in some instances, the same or related plants were used over wide geographic regions, which also was the result of communication and/or the importation of plant material of high repute. Thus, the Nordic countries have an ancient, rich and diverse history of plant derived anthelmintic medications for human and animal use. Although some of the more commonly used herbal de-wormers were derived from imported plants, or their products, many are from endemic plants or those that thrive in the Scandinavian environment. With the advent of the modern chemotherapeutic era, and the discovery, development and marketing of a seemingly unlimited variety of highly efficacious, safe synthetic chemicals with very wide spectra of activities, herbal remedies virtually disappeared from the consciousness--at least in the Western world. This attitude is now rapidly changing. There is a widespread resurgence in natural product medication, driven by major threats posed by multi-resistant pest, or disease, organisms and the diminishing public perceptions that synthetic chemicals are the panacea to health and disease control. This review attempts to provide a comprehensive account of the depth of historical Nordic information available on herbal de-wormers, with emphasis on livestock and to provide some insights on potentially rewarding areas of "re-discovery" and scientific evaluation in this field.

First record of autochthonous canine ehrlichiosis caused by Ehrlichia canis in Romania

This case study describes the first genetically confirmed and clinically manifested autochthonous Ehrlichia canis infection in a 9‐year‐old female mixed‐breed dog from Romania. Health screening of the dog included clinical examination, evaluation of stained peripheral blood smear and hematologic variables, as well as serologic testing and molecular analysis. Clinical signs included fever, apathy, dehydration, pale mucous membranes, and weakness. The microscopic examination of the blood smear and immunologic assays for Borrelia burgdorferi, Anaplasma phagocytophilum, and E canis antibodies, and for Dirofilaria immitis antigen yielded negative results. Hematologic abnormalities included moderate nonregenerative anemia, leucopenia with neutropenia, and moderate thrombocytopenia. The biochemical abnormalities identified were hypoalbuminemia, and mildly increased serum enzyme activities of AST and ALT. In addition, increased urea and creatinine levels associated with low urine specific gravity and proteinuria were also present. Nested PCR amplification of the partial E canis 16S rRNA gene demonstrated the presence of this rickettsial pathogen in the dog's blood, which subsequently was confirmed through sequencing based on the 100% homology with GenBank deposited E canis isolates. After specific treatment with doxycycline (10 mg/kg, orally, SID) for one month, the proteinuria, and hematologic and serum biochemical abnormalities with the exception of mild azotemia resolved. This report supports the geographical expansion of canine ehrlichiosis caused by E canis in nonendemic regions of Europe.
