“…T. canis is the most common canine intestinal endoparasites worldwide. Humans are infected by Toxocara via ingestion of embryonated eggs in contaminated soil [66]; however, pet hair can also contain embryonated eggs [67]. The first importance reports about human toxocariasis in Russia were published in 1961-1962 [68,69].…”

Dogs are the hosts for a wide helminth spectrum including tapeworms, flatworms, and nematodes. These parasites affect the dog health and cause morbidity and mortality, especially in young and old animals. Some species, as Toxocara canis, Ancylostoma caninum, Dipylidium caninum, and Echinococcus spp. are well-known zoonotic parasites worldwide, resulting in high public health risks. Poor data about canine helminth species and prevalence are available in Russia, mainly due to the absence of official guidelines for the control of dog parasites. Moreover, the consequent low quality of veterinary monitoring and use of preventive measures, the high rate of environmental contamination by dog feces and the increase of stray dog populations, make the control of the environmental contamination by dog helminths very difficult in this country. This paper reviews the knowledge on canine helminth fauna and prevalence in Russia. Practical aspects related to diagnosis, treatment, and control of parasitic diseases of dogs in Russia are discussed.

“…Similar results were also reported by El-Tras et al [23] for domestic dogs, whilst for stray dogs, two animals (3.8%; CI 95% = 0.7–14.1%) showed positive hair samples, but negative fecal samples. Finally, Oge et al [43] did not find dogs positive for fur and feces contemporaneously.…”

Simple SummaryAnimal-assisted interventions (AAIs) represent an opportunity for the well-being and health of people, but it is necessary that the animals involved in these interventions are subjected to very thorough health checks in order to avoid the potential risk of zoonoses transmission. Dogs are the main animal species involved in AAIs and may represent a potential reservoir of zoonotic agents (e.g., bacteria, parasites, fungi). Some scientific contributions have been published regarding healthcare checks and related hygiene measures for dogs involved in these interventions, but no attention has been paid to the presence of Toxocara eggs on the fur. Thus, a systematic review was carried out to address this topic. Although the infection of humans through the transmission of Toxocara eggs after direct contact with dogs must be critically challenged, we suggest including the examination of fur during a complete parasitological screening of dogs involved in AAIs in order to exclude hair coat contamination with zoonotic helminth eggs. Moreover, it is important to also monitor the behaviors of dogs that can increase the risk of contamination from the environment (e.g., roll on grass and feces of other dogs or cats) as well as the life habits of dogs (e.g., outdoor or indoor).AbstractAnimal-assisted interventions (AAIs) usually contribute to the well-being and health of users/patients, but it is essential that the animals involved in these activities do not represent a source of zoonoses. This systematic review focused on the evaluation of the potential risk of the transmission of Toxocara by dogs’ fur, considering their involvement as the main animal species in AAIs. Three databases were considered: MEDLINE/PubMed, Scopus, and Web of Science, and the PRISMA guidelines were used. Out of 162 articles found, 14 papers were identified as eligible for inclusion in the review. Although the findings were very heterogeneous, they showed that regular parasitological surveillance to plan effective control programs is strongly needed to guarantee the health of pets and consequently the public health, according to the concept of One Health. Since AAIs involve patients and/or users potentially susceptible, it is very important to appropriately treat dogs enrolled in these interventions after an accurate diagnosis of parasitic zoonoses.

“…VLM in humans occurs primarily because of the ingestion of infective eggs (Macpherson, 2013; Strube et al, 2013). The ways of transmission to humans are as follows; soil and sandpits contamination in children, geophagia (Overgaauw & Nederland, 1997; Macpherson, 2005; Bowman, 2009), ingestion of eggs contain infective larvae from dog’s coat (Amaral et al, 2010; Macpherson, 2013; Öge et al, 2014), consumption of unwashed raw vegetables or fruits (Kozan et al, 2005; Lee et al, 2010), consumption of raw or undercooked meat containing arrested infective larvae in paratenic host (Lee et al, 2010; Macpherson, 2013; Strube et al, 2013), low socio-economic level and failure to regularly pick up and dispose of faeces (Overgaauw & Nederland, 1997; Robertson & Thompson, 2002).…”

SummaryFaecal samples were collected from 224 dogs (47 villages) in Ankara. Toxocara spp. eggs were diagnosed in faeces using centrifugal flotation and sedimentation methods. A total of 21 dogs (9.38 %) were positive for Toxocara spp. eggs. In this study, we used the PCR technique that, in combination with DNA sequencing, allows the detection and identification of T.canis eggs in faeces of infected dogs. For this purpose, the ATPase subunit-6 gene (mtDNA) was selected as a target for the amplification T. canis. The primers were used to amplify 217 bp region. Amongst 21 coproscopically detected Toxocara isolates from dogs, 5 (23.8 %) samples were PCR-positive for T. canis, and the remaining 16 samples were PCR-negative. Results indicate that PCR can detect Toxocara canis DNA in faeces of infected dogs, but efficacy was low when compare to sedimentation/flotation. PCR is additional test for diagnosing of this infection. But, the difficulties of identification based on PCR in faecal examinations need to be investigated further.
