Samples underwent DNA extraction and nested PCR targeting the rap-1a gene for B. bigemina detection. Animals were categorized by sex, age class, and tick presence during sampling. An epidemiological questionnaire assessed potential risk factors. The overall B. bigemina prevalence was 60% (186/311; 95% CI: 56,95%-62,67%). Males showed significantly higher infection rates (79%; 49/62) compared to females (55%; 137/249; OR=3.36, p<0.001). Bulls (81%; 26/32) and calves (78%; 56/72) exhibited higher infection rates than cows (50%; 70/141) and heifers (52%; 34/66; p<0.001).

This study aimed to conduct a quantitative and qualitative survey of the entomofauna in urban and peri-urban areas of Lages, Santa Catarina, Brazil, and to analyze documented cases of canine leishmaniasis in the city, in response to the rising number of non-autochthonous cases in dogs. The lack of prior studies on this fauna in the municipality raises concerns for public health services. Nine areas were monitored over the course of one year, and clinical and epidemiological records of canine leishmaniasis in the city were analyzed. A total of 10,638 insects were collected, with no phlebotomine sandflies identified. All evaluated cases of canine leishmaniasis were classified as non-autochthonous based on the movement history of these animals and the absence of the disease vector in the municipality.

The parasitological techniques of Willis, Sheather, Faust, Hoffman-Pons-Janer-Lutz and Rugai staining were then performed. The positivity rate of endoparasites in the analyzed samples was 19.2%, with a predominance of hookworm eggs. Cystoisospora spp. and Hammondia hammondi oocysts were also found, with a case of co-infection with the two species. No statistical difference in positivity was found between household and stray cats. However, a significant difference was found upon evaluating sex and neutering status, revealing that male cats and non-neutered animals showed higher positivity rates, with 28.8% of non-neutered animals testing positive compared to 9.83% of neutered animals.

Over the last five years, 12 cases of D. renale have been reported in domestic and wild canids, two of which are described in full in this study. The expansion of livestock farming and urbanization of biomes, fragmentation of floral areas, and destruction of natural areas have increased the proximity between domestic and wild animals, and consequently, the occurrence of infectious and parasitic diseases.

All the animals were parasitized, and a total of 50 specimens representing the Acanthocephala Phylum were recovered, which morphologically showed characteristics compatible with Prosthenorchis elegans (Diesing, 1851). Light microscopy revealed the presence of parasites attached to the mucosal layer, passing through the underlying layers until they reached the muscular layer. Scanning electron microscopy showed the tissue lesions caused by the proboscis hooks and the flattening of the intestinal villi in the presence of the parasite.
