In many countries, urban areas are commonly contaminated with canine feces that spread parasites, a situation related to the natural and social environment. Dogs having free access to public areas therefore constitutes a health risk. Because in Patagonia there are no records of city comparisons that consider the number of free-roaming dogs and the local environmental and socioeconomic characteristics, in this study we analyse and compare canine parasitoses in two cities of Rio Negro province, Argentina. Canine feces were collected from public areas of El Bolsón and Cipolletti cities and examined using enrichment methods, Kinyoun stain and immunoassay (Copro-Elisa). The total percentage of positive feces in El Bolsón was 68.95% and 16 parasite taxa being identified, whereas in Cipolletti the total positive feces was 41.1%, with 11 taxa. Both cities presented more helminth species than protozoans. The variables that explained the occurrence of all parasites were rainfall and socioeconomic stratum with the highest values being found in low-income areas.Soil moisture is conditioned by rainfall. This study highlights the presence of the zoonotic sp. in dogs in urban areas of the Rio Negro province. The occurrence of this parasite in Cipolletti is unexpected, given that this city is not considered an endemic zone for this disease, which is not included in local monitoring and control plans.

Article Synopsis
- Heartworm disease in dogs, caused by the parasite Dirofilaria immitis, is hard to treat but easy to prevent with medications called macrocyclic lactones (MLs).
- A recent case in Rome described a dog that tested positive for heartworms after arriving from the USA, despite treatment with MLs, indicating the presence of a resistant strain.
- Genetic analysis confirmed the dog's infection was caused by a ML-resistant strain, raising concerns about the risk of such strains spreading into Europe and underscoring the need for monitoring dogs from regions known for ML-resistance.

Parasitic diseases caused by uncommonly diagnosed parasites may pose a threat to companion animals' health in urban environments where they are least expected. The pentastomid Linguatula serrata (tongue worm) and the capillarid Pearsonema plica (syn. Capillaria plica) are parasites with an indirect life cycle, infecting both domestic and wild carnivores.

Article Synopsis
- Toxocariasis is caused by nematodes from the Toxocara genus, which primarily affect dogs and cats, with humans acting as incidental hosts.
- The study analyzed 734 patient samples for Toxocara canis antibodies from October 2014 to October 2019, revealing a 41.8% seroprevalence, particularly affecting children aged 11 and younger, and predominantly males.
- The findings highlight a high prevalence in Pará state and stress the importance of further research and health campaigns targeting both domestic and stray animals to improve control and surveillance of parasitic infections.

Article Synopsis
- Several copromicroscopic techniques, like conventional flotation and Mini-FLOTAC, were evaluated for diagnosing parasitic infections in dogs and cats using fecal samples from 205 animals in Italy.
- The study found that flotation and Mini-FLOTAC methods detected the highest rates of positive samples in both species, with specific larvae only identified by the Baermann test in a few cats.
- Ultimately, while Mini-FLOTAC can serve as a useful alternative for diagnosing various intestinal and respiratory parasites, Baermann's test remains the top choice for detecting metastrongyloid lungworm infections.
