The objective of this study was to identify the canine and feline gastrointestinal parasites (GIP), domiciled and non-domiciled, in seven cities in the state of Pernambuco and, thus, to evaluate the environmental contamination and the risk of transmission of parasites with zoonotic potential. Two hundred fifty-six fecal samples from canines (n=183) and felines (n=73) were collected, which were processed by the modified Sheather flotation (with 1.3d hypersaturated sucrose solution) and the spontaneous sedimentation methods. In 86 (33.6%) samples, helminths and/or protozoa were detected. The GIP identified in dogs were: Ancylostoma sp. (42/55; 76.4%), Trichuris vulpis (9/55; 16.4%), Toxocara canis (5/55; 9.1%), Strongyloides stercoralis (3/55; 5.45%), Dipylidium caninum (3/55; 5.45%) and Cystoisospora sp. (3/55; 5.45%). In cats, Toxocara. cati (5/30; 16.6%), Coccidia (19/30; 63.3%), Dipylidium caninum (3/30; 10%) and Ancylostoma sp. (3/30; 10%). Five of the eight GIP identified have zoonotic potential. These results demonstrate the importance of parasitological diagnosis based on the identification of parasites that can affect not only animal health, but also human health from environmental contamination. This study should support health education actions with tutors and continued training with veterinarians for the prevention of gastrointestinal parasites in animals and the transmission of parasitic zoonoses from the perspective of One Health, which advocates the mitigation of health risks at the interface animal-human-environment.

The opossums are synanthropic mammals belonging to the genus Didelphis. They have a generalized diet, and this behavior exposes them to the chance of infection by several parasitic agents. Their close relationship with the human makes them act as disseminators of pathogens. The objective of the study was to evaluate the diversity of endoparasites infecting D. albiventris sampled in Canoinhas, Northern Santa Catarina. Thirty-eigth fecal samples were macro and microscopically analyzed, and of these 89.47% showed positivity for at least one endoparasite, 89.47% (34/38) for helminths and 60.52% (23/38) for protozoa. Nematode eggs of the order Strongylida and the genera Cruzia, Trichuris, Aspidodera, Physaloptera, Capillaria and Strongyloides were observed, as well as trematode eggs and oocysts of protozoa. In 38.3% of the animals four parasite types were detected, showing high occurrence of endoparasites and that multiparasitism is frequent in this species. [ABSTRACT FROM AUTHOR]

Around 20% of losses in animal productivity are directly related to parasites, which are, for the most part, acquired through a contaminated environment. On the other hand, sodium hypochlorite, popularly known as bleach, is used as a chemical disinfectant. The objective of the present work was to evaluate the action of 2.5 and 5% sodium hypochlorite on the larval development of strongyles in coprocultures. Three experimental groups were formed in coprocultures: G1 (10 grams of feces + 20 g of vermiculite + 5 mL of 2.5% sodium hypochlorite), G2 (10 grams of feces + 20 g of vermiculite + 5 mL of sodium hypochlorite 5%), G3 (10 grams of feces + 20 g of vermiculite + 5 mL of distilled water). After forming the groups, the coprocultures were incubated at 28°C for 10 days. After this period, L3 were extracted, quantified, and identified. The results demonstrated a reduction in the recovery of L3 from stool cultures in the treated groups compared to the control group. The percentage of L3 reduction was 97.8% in G1 and 99.5% in G2. The most observed strongyle species at the end of the experiment were: Haemonchus contortus (65%), Cooperia spp. (20%), Trichostrongylus spp (10%) and Oesophagostomum (5%). It is concluded that the use of sodium hypochlorite in the concentrations evaluated can be used in the routine of rural properties in the facilities and thus help to reduce the recurrence of helminthiasis in cattle.
