“…Similar results were obtained by other scientists (Gebremedhin et al, 2020), who found that the probability of infection with T. canis is 4.5 times higher in young dogs than in adults. Motta et al (2019) and Stafford et al (2020), like previous authors, indicate that the age of dogs increases the risk of infection with the nematode T. canis and do not consider the spread of T. vulpis related to the age of the owner. However, some publications describe an increased risk of T. vulpis infection in older dogs (Symeonidou et al, 2017).…”

Trichuris vulpis and Toxocara canis are worldwide parasitic nematodes affecting dogs and mammals of the Canine family. Due to the special structure of the shells, the eggs of these geohelminths can maintain their viability in soil, sand, water and the environment for a long time. The study involved young (6–12 months old) and adult (1.5–8.0 years old) dogs affected by co-infection of T. vulpis + T. canis; the control group consisted of dewormed healthy animals of the same age. Parasitological examination of dogs' faeces was performed using a "Counting Chamber for Ovoscopic Researches"; morphological parameters, indicators of nutrient metabolism, mineral metabolism and activity of enzymatic systems were determined in blood and serum. According to the results of parasitological research on the dogs, it was found that young animals are more prone to toxocarosis, and adults – trichurosis. The co-infection of nematodes T. vulpis + T. canis in dogs develops several changes in haematological parameters: a significant decrease in erythrocytes, haemoglobin, MCV, MCH, and haematocrit, leukocytosis with basophils and eosinophilia in young infected animals; and eosinophilia and basophilia (15.9 times) in adults, compared with healthy dogs of the same age. Among the changes in serum biochemical parameters, young infected dogs showed a decrease in the concentration of total protein and albumin content, an increase in the content of "acute phase" proteins (α-1, α-2 and β-globulins), an increase in cholesterol and total bilirubin; in adult infected dogs, a decrease in albumin content, an increase in the content of α-1, α-2, and β-globulins, an increase in the concentration of cholesterol and total bilirubin, a decrease in the concentration of urea in comparison with healthy animals were determined. Also, among the indicators of mineral metabolism, a decrease in the concentration of calcium and magnesium in the serum was found in young infected dogs. Among the changes in the enzyme metabolism in the serum of infected dogs, there was an increase in the activity of all studied enzymes in animals of both research groups: ALT, AST, α-amylase, GGT and ALP. Thus, co-infection with nematodes T. vulpis + T. canis has a complex pathogenic effect on the body of dogs of all ages, which manifested itself in multiple changes in haematological parameters. In the future, the authors’ team plan to develop comprehensive measures to combat nematode infections in different living conditions of dogs, taking into account the results of the current research.

“…There was also an increased risk of infection associated with age for Т. canis, Cystoisospora spp., and Giardia spp. (Motta et al, 2019). Researchers on the zoonotic agents' prevalence in Merida (Yucatan, Mexico) found that 11.0% of faecal samples collected from city's public parks tested positive for intestinal nematode eggs.…”

In South America there are more dogs per person than in developed countries. Many owners allow their dogs to roam freely in public areas, which favours the spread of zoonotic diseases. The objective of this work is to describe, through bibliographic analysis, the occurrence, prevalence, species richness, and distribution of intestinal helminth parasites found in dog faeces from urban and rural areas of southern South America (Argentina-Chile-Uruguay). Using three databases, we performed a systematic review of articles published between 2000 and 2020 in indexed journals. A total of 219 articles was evaluated for eligibility, and of these 67 were included in the final analysis; 48 correspond to Argentina, 17 to Chile, and 2 to Uruguay. The total number of parasite taxa recorded was 22, the most frequently occurring species being Toxocara canis, Ancylostoma sp., Trichuris vulpis and Echinococcus sp. Species richness was correlated with sample size and varied between 1 and 10 species. In addition, disease risk is not homogeneously distributed. Due to the high infection levels in dogs, urban and rural dwellers are at risk of infection with zoonotic diseases transmitted by these animals, therefore a One Health approach to public health would be advisable.
