Mice are widely used as laboratory animals. Diagnosis of endoparasites is a necessary condition: this is a culling indicator of animals for SPF (specific pathogen free) vivariums, and for conventional vivariums, it is the necessary information for planning and the possibility of using these animals in various tests. This article describes live-time diagnostics of endoparasites in laboratory mice in SPF vivariums and in open-type vivariums. For the study, individual samples of faeces and bedding were taken from laboratory mice. Direct fecal smears were examined and the flotation method was used. The work was carried out in 2021–2022 in the Laboratory of Biology and Biological Basis of Preventive Measures of the VNIIP – FSC VIEV. During this study, the following 180 samples were taken: 138 individual faecal samples, 34 samples combined with the bedding, and 18 bedding samples. The studied samples were found to contain Giardia muris and Tritrichomonas sp., nematodes Aspiculuris tetraptera and Syphacia obvelata, and cestode Rodentolepis nana. Mixed invasions were also recorded. The results showed the need for planning work with laboratory mice in vivariums.

The existing interest in the problem of toxoplasmosis is largely due to the fact that Toxoplasma gondii plays a significant role in human pathology. Toxoplasmas enter the human body in many ways: through the mouth when eating raw meat; with contaminated products, vegetables or fruits; with dirty hands, after contact with infected animals; through damaged skin, mucous membranes, when removing skins from infected animals or dividing carcasses; in medical procedures in patients with toxoplasmosis; and prenatally, from mother to fetus. Toxoplasmosis is more common in children, while adults may remain asymptomatic carriers of the pathogen. The reliability of invasion in humans is only established by the detection of toxoplasma in the blood, sputum, cerebrospinal fluid, puncture samples of lymph nodes, remnants of fetal membranes, placenta, etc. Therefore, the purpose of our study is to determine the occurrence of toxoplasmosis in the Krasnodar Territory for 5 years (2018–2022) and to identify organ systems that are affected most often. Toxoplasmosis is widespread in the Krasnodar Territory. This is due to climatic and geographical features. The study used data from outpatient medical records of people with diagnosed toxoplasmosis who seek medical advice in infectious diseases hospitals of the Krasnodar Territory.

The article presents data on infection of fish of the cyprinid family (ide, dace, roach) with metacercariae of trematode Posthodiplostomum cuticola. Fish for the study were caught in the following water bodies of the Novosibirsk Region: the Chulym, Karakan, Inya, and Makhalikha Rivers, as well as from the left (Sharapovsky Bay) and right (Tulkinsky Bay) banks of the Novosibirsk Reservoir. Fish were studied by the compressor method generally accepted in parasitology and by partial helminthological dissection. A total of 270 fish specimens (71 ides, 82 daces, and 117 roaches) were studied. To analyze the fish infection, such indicators as the invasion prevalence and intensity, as well as the abundance index were used. The research results showed that the overall level of infection of cyprinids with P. cuticola metacercariae in the reservoirs of the Novosibirsk Region was 13.0%. The highest invasion prevalence of 35.2% was observed in ides; in daces and roaches this value is much lower and amounts to 7.3% and 3.4%, respectively. The invasion intensity was low, ranging from 1 to 7 parasite specimens per fish. The highest average invasion intensity of 3.3 and 3.1 specimens was recorded in daces from the Karakan River and ides from the Chulym River.

On the territory of the slaughterhouse located in the Moscow Region, a veterinary and sanitary assessment of carcasses and internal organs was carried out in accordance with the Customs Union Technical Regulations "On the safety of meat and meat products" No. 68 TR CU 034/2013 dated 09/10/2013 for the infection with larval cestodiasis. As a result, 3 species of pathogens were recorded: Echinococcus granulosus, Cysticercus taenuicollis and Coenurus cerebralis. E. granulosus larvae was detected in the parenchymal organs in 211 cases, which corresponds to 42.2%. It is worth noting that the blister cavities were localized in the liver in 23.7%, in the lungs in 15.6%, and in both organs in 2.9%. From 1 to 8 blisters were found. In addition to echinococcosis, coenurus blister cavities were found in 2 animals, and Cysticercus tenuicollis, in 22 sheep from the Karachay-Cherkess Republic; the IP was 2.0 and 22.4%, and tenuicollic cysticercosis infection in the Astrakhan and Volgograd Regions was 2.9 and 6.0%, respectively. Such a wide spread of echinococcosis is a fairly high indicator for such a particularly dangerous zoonosis, as parenchymal organs can be a source of infection for dogs, and subsequently for humans.
在位于莫斯科州的屠宰场境内，根据2013年10月9日第68 TR CU 034/2013号关税同盟技术法规“关于肉类和肉类产品的安全”，对尸体和内脏进行了兽医和卫生评估，以确定是否感染幼虫囊虫病。结果共检出细粒棘球蚴、带状囊尾蚴和脑棘球蚴3种病原体。211例肺实质器官检出细粒绦虫幼虫，占42.2%。值得注意的是，23.7%的水疱空洞位于肝脏，15.6%位于肺部，2.9%位于两个器官。发现1 ~ 8个水泡。除棘球蚴病外，在2只动物中发现了棘球蚴水疱，在卡拉恰伊-切尔克斯共和国的22只羊中发现了细囊尾蚴;感染率分别为2.0和22.4%，阿斯特拉罕和伏尔加格勒地区的细粒囊尾蚴病感染率分别为2.9和6.0%。棘球蚴病的如此广泛传播是这种特别危险的人畜共患病的一个相当高的指标，因为实质器官可能是狗的感染源，随后是人类的感染源。

The main purpose of the work was to identify helminth and protozoan parasite infections and helminthozoonosis in domestic dogs of different age groups in Moscow. Coproovoscopic examinations were carried out during 2022 for dogs older than a year and puppies up to 6 months from 5 administrative districts of the City. Fecal samples were collected in defecation of dogs individually in a sterile container with the animal information on the label during dog walking by their owners. Infection of the dogs was found with the following zoonotic helminths: Toxocara canis, Toxascaris leonina, Dipylidium caninum, and Taenia spp.; and protozoa: Isospora canis. Toxocara canis reached its maximum value in the puppies up to 6 months of age with the prevalence of 33.3%, and in the dogs older than a year with the prevalence of 15.3%. Toxascaris leonina was not found in the puppies under 6 months of age; in the dogs older than a year, it reached the maximum invasion value with the prevalence of 9.5%. Dipylidium caninum reached the maximum invasion value in the puppies aged up to 6 months with the prevalence of 7.8%, but the dogs older than a year were not found to have Dipylidium caninum. Taenia spp., were found neither in the puppies nor in dogs older than a year.

The effect of the tested substances on in vitro nematicidity and nematostaticity was verified on saprobiotic (Caenorhabditis elegans, Turbatrix aceti) and phytoparasitic nematodes (Ditylenchus destructor). Working solutions were prepared in the following dilutions: 1) 1/1000, 2) 1/100, 3) 1/10, 4) 1/1, 5) undiluted, 6) control, water, and 7) standard (horseradish root juice). The solution of above concentrations was introduced into the plate wells of 0.5 mL in 4 repetitions, then a well-mixed nematode suspension of 0.5 mL was added with 50±10 nematodes in average. After 24 hours of hold-times, mobile and immobile nematodes were counted, then after 48 hours nematodes were counted again. At the end of the experiment, nematodes were washed from the drug in order to determine the nematostatic effect. In vitro screening showed that the horseradish root juice, black nightshade berry juice, and red nightshade leaf and berry juice had nematicidal properties. The nematostatic effect was recorded in shoots of the green tuber, tissues of the green surface of the tuber and tuber juices, juice of red nightshade leaves, and juice of black nightshade leaves and berries.

The purpose of the research is to compare diagnostic and design characteristics of Gastros and AVT-L devices in order to determine the prospects for improving the veterinary and sanitary examination of carcasses with trichinellosis. Taking into account the requirements for ensuring the safety of food products, in particular meat and meat products, special requirements are imposed on the quality of trichinelloscopic control in the conditions of veterinary diagnostic laboratories of meat processing enterprises, markets and slaughterhouses. For this purpose, a fairly wide range of devices is used for both compressor trichinelloscopy and peptolysis of muscle tissue. Comparative tests were carried out for Gastros of Petrolaser LLC and AVT-L (VNIIP) type devices used for this purpose. In the process of work, we analyzed the features of the examination technology, the structural elements of the devices and the diagnostic efficiency. In general, the devices met the requirements of the veterinary and sanitary examination for trichinellosis in various production conditions, however, their design for manufacturability had significant differences. With equal diagnostic efficiency, the devices have significant design differences regarding the type of thermal stabilization, automation, control systems for the duration of the peptolysis and settling of the medium, and the dimensions of the devices. According to these parameters, Gastros is more promising at the present time. AVT-L requires some improvements.
本研究的目的是比较Gastros和AVT-L装置的诊断和设计特点，以确定改进旋毛虫病尸体兽医和卫生检查的前景。考虑到确保食品，特别是肉类和肉制品安全的要求，对肉类加工企业、市场和屠宰场的兽医诊断实验室的条件进行旋轮镜控制质量提出了特殊要求。为此目的，相当广泛的设备被用于压缩旋旋镜检查和肌肉组织的胃解。对Gastros of Petrolaser LLC和AVT-L (VNIIP)型设备进行了对比试验。在工作过程中，我们分析了检测技术的特点、设备的结构要素和诊断效率。总的来说，这些设备在各种生产条件下都满足旋毛虫病兽医和卫生检查的要求，但其可制造性设计存在显著差异。在诊断效率相同的情况下，这些设备在热稳定类型、自动化、培养基水解和沉淀期间的控制系统以及设备的尺寸方面存在显著的设计差异。根据这些参数，目前胃是比较有前途的。AVT-L需要一些改进。

AVT-L requires some improvements.","PeriodicalId":22969,"journal":{"name":"THEORY AND PRACTICE OF PARASITIC DISEASE CONTROL","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76319494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this work was to clarify the species composition of acanthocephalans of Baikal waterbirds and to determine their relative abundance in modern environmental conditions. Ninety nine specimens of 13 species of waterfowls were studied by the method of special and complete dissection in Lake Baikal. Birds were studied according to the method given in the work by M. N. Dubinina. Three species of acanthocephalans were recorded: Polymorphus minutus (Goeze, 1782), P. acutis Van Cleave et Starret, 1940, and P. magnus Skrjabin, 1913. To assess the quantitative parameters of host infection, the following indices were used: prevalence of invasion (iP), intensity of invasion (iI, limits) and abundance (A). P. minutus was the most widespread species of acanthocephalans. Acanthocephalans are localized in the small intestine of birds. Polymorphae penetrate very deeply into the small intestine wall of the host. Unlike echinorhynchids whose proboscis penetrates only into the submucosa of the intestinal mucosa of fish, the proboscis and neck of polymorphids pierce the mucous and muscular membranes reaching the serous membrane. Tubercles are observed on the outer, serous side of the intestine that mark places of attached acanthocephalans. With a high number of definitive hosts, they can potentially exert a regulatory influence on the number of bird populations.
本研究的目的是阐明贝加尔湖水鸟棘头目的种类组成，并确定其在现代环境条件下的相对丰度。对贝加尔湖的13种水禽进行了全面解剖，共99种标本。根据M. N. Dubinina工作中给出的方法对鸟类进行了研究。棘头类有3种:Polymorphus minutus (Goeze, 1782)， P. acutis Van Cleave et Starret, 1940, P. magnus Skrjabin, 1913。采用入侵流行度(患病率)、入侵强度(极限)和丰度(A)等指标评价宿主感染的定量参数。棘头类动物局限于鸟类的小肠。多态菌深入宿主的小肠壁。与棘吻鱼不同，棘吻鱼的喙只穿过鱼肠粘膜的粘膜下层，多形鱼的喙和颈穿过粘膜和肌肉膜到达浆膜。在肠的外侧浆液面可见结节，标志着附着的棘头体。由于具有大量的最终宿主，它们可能对鸟类种群的数量施加调节影响。

The article provides information on the harmful effect of horseflies (Diptera, Tabanidae) as a midge component and a vector (carrier) transmitting pathogens of infectious and parasitic diseases including zoonosis. Horseflies are harmful to animals and humans in places of their abundance. Horseflies cause significant economic losses to livestock. With an intense attack of horseflies, individual areas of the skin of animals represent a continuous bleeding surface. Horsefly saliva inserted into a wound at the time of the bite is very toxic and allergenic causing a local inflammatory process and general intoxication of the body. The insects are of particular danger as vectors transmitting pathogens of animals and humans. The role of horseflies in the transmission of tularemia in natural foci of this infection has been proven. The sources of horsefly infection are primarily various small mammals including water rats. Horseflies are equally important as carriers of the anthrax pathogen. Causative agents of Coxiella burnetti infection, blackleg, pasteurellosis, and other infections have been isolated from horseflies. Horseflies are involved in the transmission of Trypanosoma evansi in horses and camels, anaplasmosis in cattle, Theileria cervi in reindeer, and equine infectious anemia virus.

The ecosystems of the south-east of the Northern Caspian Sea are inhabited by three representatives of artiodactyls, namely, the Daghestani (East Caucasian) tur, the chamois (wild mountain goat) and the roe deer. All three species are under the state protection and listed in the Red Book. The helminth biodiversity in these three species of ruminants has been studied for 35 years due to the fact that the hunting is prohibited, therefore it is very difficult to collect material for research. The collected material analysis showed that helminth biodiversity in the Daghestani tur was represented by 20 species, chamois by 16 species, and roe deer by 15 species. From the trematode and cestode classes, 2 species of F. hepatica, D. lanceatum, M. expansa, and M. benedeni were recorded. The rest of the fauna was represented by nematodes including 22 species from the suborder Strongylata, one species of G. pulchrum from Spirurata and one species of T. ovis from Trichocephalata. The invasion prevalence (IP) of helminths in the Daghestani tur varied from 3.5 to 14.2% with the invasion intensity (II) of 1–12 specimens, respectively, in the chamois up to 8.3% and 2–5 specimens, and in the roe deer 4.1–8.3% and 1–4 specimens. The largest number of species were represented by the genera Nematodirus, Ostertagia, and Trichostrongylus.
