We comparatively evaluate two distinct formulations containing 5% of Jucá (Libidibia ferrea) for wound healing in dogs. An excision model study was performed 11 dogs with three dermal wounds each animal, which were treated with: (1) topical phytopharmaceutical based on Carbopol (PyC) ethanolic extract; (2) Astrocaryum murumuru butter (PyM) and (3) commercial ointment (control). Wound treatment carried out alternated days starting at day (D) one until D21. Macroscopic (all time-points)...

Previous studies have reported high diversity between and within populations of Toxoplasma gondii in South America. In the present study, isolates T. from chickens were obtained Amazon region. Adult free-range acquired 29 municipalities Brazilian region that included Acre (n = 9 municipalities), Amapá 6), Amazonas Pará Roraima 2) states two Peru, three Bolivia, one Guyana, Venezuela. Heart, brain, blood samples collected 401 chickens. Anti- serum antibodies detected 273 (68.1%) using...

Trypanosoma comprises flagellates able to infect several mammalian species and is transmitted by groups of invertebrates. The order Chiroptera can be infected the subgenera Herpetosoma, Schizotrypanum, Megatrypanum Trypanozoon. In this study, we described diversity bat trypanosomes inferred phylogenetic relationships among from bats caught in Tapajós-Arapiuns Extractive Reserve (Resex) Pará state. Trypanosomes were isolated means hemoculture, molecular phylogeny was based on trypanosome...

Cyperus articulatus L. is popularly known as priprioca. Its rhizomes are used a medicine in the treatment of malaria traditional medicine. Since priprioca oil extracted for commercial purpose, we evaluated if components from residue can be source antiplasmodial active molecules. This study aimed to determine vitro and cytotoxicity activities ethanolic extract C. an agent. From solid plant rhizomes, 40 g samples were removed subjected hot extraction using Soxhlet extractor. The activity was...

Leukoreduction (LR) is a technique that consists of reducing the number leukocytes in whole blood or components can contribute to decreasing storage lesions and occurrence post-transfusion complications. We propose using bag with pre-storage leukocyte filtration sufficient for conservation under field conditions. Ten healthy Nelore cows were used. Whole was sampled from each animal stored at 2 6 °C CPD/SAG-M (citrate phosphate dextrose saline, adenine, glucose, mannitol satellite bag) triple...

Malaria is an infectious and parasitic disease caused by protozoa of the genus Plasmodium, which affects millions people in tropical subtropical areas. Recently, there have been multiple reports drug resistance Plasmodium populations, leading to search for potential new active compounds against parasite. Thus, we aimed evaluate vitro antiplasmodial activity cytotoxicity hydroalcoholic extract Jucá (Libidibia ferrea) serial concentrations. was used form a freeze-dried extract. For assay,...
