Ascariasis is frequently diagnosed in the dog population, and Toxocara canis is the main agent that causes larva migrans syndrome in humans. In big cities, the number of pets is constantly increasing, especially canids. In Romania, in addition to dogs with owners, a large number of dogs without owners are found in public green spaces. Timisoara is one of the largest cities in Romania, with a population of approximately 306.462 people. In the present study, the seroprevalence of anti-T. canis antibodies was investigated in different age groups using the ELISA method. The samples were taken and analyzed in a private laboratory. The results indicated a major deficiency in the control of ascariasis in animals. The overall seroprevalence recorded in 371 individuals who were referred to the laboratory during 2017-2020 was 22.64%. The elderly were the most affected (39.39%) and children were the least affected (7.4%) groups.

Introduction: Gastrointestinal parasitic infestations are one of the major health concerns worldwide; hence, this study aimed to investigate the efficacy of a doramectin-based anti-parasitic drug. Methods: To achieve this goal, we collected fresh faecal samples (50-100 g) from 20 sheep and 20 cattle, which were subsequently examined through coproparasitic methods. Results: Pre-therapeutic coproscopic screening of samples from sheep and cattle led to the identification of digestive strongyles, Eimeria spp., Balantidium coli, Cestodes, and Toxocara spp. The prevalence rates for sheep were 100%, 35%, 35%, 30%, and 15%, respectively, and 80%, 30%, 30%, 10%, and 10% for cattle. Conclusion: The study led to the identification of parasites belonging to three different species: Sporozoa, Nematoda, and Cestoda. None of the investigated helminths proved resistant to Dectomax®, meaning that the average efficacy rate of Dectomax® in sheep and cattle naturally infected with digestive strongyles, Eimeria spp. or Toxocara spp. was 94% and 95%, respectively.
