“…Along with this, it was found that under the conditions of the canine center, the source of environmental pollution by exogenous forms of helminths T. canis is the fly Musca domestica L. (Paliy et al, 2018b). 26% of sand samples contaminated with T. canis helminths were identified (Ristić et al, 2020).…”

Disinfection of environmental objects with highly effective disinfectants is a reliable and effective means of preventing the occurrence of outbreaks of infectious and parasitic diseases. The purpose of our work was to determine the disinfection properties of modern disinfectants based on the test culture of Toxocara canis helminths and to establish the optimal modes of their use. It has been proven that an aldehyde disinfectant containing didecyldimethylammonium chloride (2.25%), benzalkonium chloride (8.0%), glutaraldehyde (15.0%), phosphoric acid, nonionic surfactants, water exhibits disinvasive activity against test cultures of Toxocara canis eggs at a concentration of 2.0-4.0% at a temperature of 20±0.5°C and an exposure of 3-24 hours, and the ovocidal efficiency is from 90.60% to 99.70%. Aldehyde disinfectant can be used for disinfection of soil (black earth, sandy loam, loamy) contaminated with Toxocara canis eggs, at a concentration of 4.0% at 6:00 exposure and a consumption rate of 3000 cm3/m2. Chlorine agent, contains dichlorantin, dimethylhydantoin (12.4-16.4%), dispersant (9.0-12%), nonionic surfactants, corrosion inhibitor, filler exhibits disinvasive activity against Toxocara canis test culture in a concentration of 3.0-4.0% with an exposure of 3-24 hours, and the ovocidal efficiency in this case ranges from 97.40% to 98.82%. The chlorine agent is effective for soil disinfection only at a depth of up to 2 cm at a concentration of 4.0% at a consumption rate of 1000 cm3/m2 and an exposure time of 24 hours.

“…degree of contamination was detected in soil samples (4-12%). T. canis (26%) and Alaria alata (16%) eggs contamination was found in the sand samples (Ristic et al, 2020). According to the results of testing faecal samples of dogs kept by owners outside their homes in Bulgaria, the overall prevalence of parasites in the gastrointestinal tract was 64.5%.…”

“…Trichuris vulpis (Froelich, 1789) and Toxocara canis (Werner, 1782) are parasitic nematodes, the definitive hosts of which are dogs and members of the Canine family. Both parasites are geohelminths, their eggs mature in the environment, maintaining viability for a long time due to the special structure of the shells (Abou-El-Naga, 2018;Bojar & Klapec, 2018;Borodai & Hodyna, 2019;Marko et al, 2020;Ristic et al, 2020). According to the results of scientific research, the geography of biohelminth distribution centres is usually more extensive, even despite the binding of intermediate nutrients to certain living conditions (Boyko & Brygadyrenko, 2017;Zazharska et al, 2018;Feshchenko et al, 2019).…”

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.

“…In Serbia, several studies related to the presence of zoonotic nematodes in wild carnivores (Ilić et al, 2016a;2016b;Hadži-Milić et al, 2016;Gajić et al, 2019), nonowner dogs (Ristić et al, 2020a;2020b), shelters dogs (Ilić et al, 2021), and owned dogs and cats (Ilić et al, 2017;Ristić et al, 2020a;Stepanović et al, 2021) have been reported, while those related to carnivorous filariasis are of special importance (Tasić et al, 2008;Tasić et al, 2012;Penezić et al, 2014;Stepanović et al, 2015;Gavrilović et al, 2015;Kurucz et al, 2016).…”

Clinical-parasitological and epidemiological review of the nematode Acanthocheilonema reconditum

et al. 2023

View full text Add to dashboard Cite

Acanthocheilonema (Dipetalonema) reconditum is a less pathogenic species of filaria from the superfamily Filarioidea, and which parasitizes in the subcutaneous connective tissue of dogs, hyenas and jackals. The results of epidemiological studies indicate the zoonotic potential of A. reconditum, bearing in mind it can cause infections with clinical disorders in humans. This filaria is spread globally and it is mostly described in geographical areas such as the Mediterranean Basin, the Middle East, South Africa, South America and Oceania, where it is the only or is the most common filaria that infects dogs. The prevalence and distribution of A. reconditum depend mainly on the vector population, impact of environmental factors, and lifestyle of pets and their owners. Apart from the standard parasitological techniques for differential diagnostics of filariae, more attention is being dedicated to the development of protocols that are based on the simultaneous detection of specific DNA regions in each type of individual filaria. Due to its importance for public health, effective vector control is required, as well as regular preventive examinations, reliable diagnostics and therapy for A. reconditum in dogs, and continuous cooperation between veterinary and medical surgeons.
