Abstract
We comparatively evaluate two distinct formulations containing 5% of Jucá (Libidibia ferrea) for wound healing in dogs. An excision model study was performed in 11 dogs with three dermal wounds in each animal, which were treated with: (1) topical phytopharmaceutical based on Carbopol (PyC) containing 5% Jucá ethanolic extract; (2) topical phytopharmaceutical based on Astrocaryum murumuru butter (PyM) containing 5% Jucá ethanolic extract; and (3) commercial ointment (control). Wound treatment was carried out on alternated days starting at day (D) one until D21. Macroscopic (all time-points) and histological (D0 and D21) analyses were performed. The antimicrobial activity of Jucá was evaluated through Minimal Inhibitory Concentration (MIC). Phytochemical analysis of Jucá revealed 3.1% phenolic compound content expressed in rutin and the presence of hydrolyzable tannins and flavonoids. The mean wound retraction was 33.7 ± 5.5, 34.0 ± 4.7, and 28.4 ± 4.9 % for PyC, PyM, and control groups, respectively, with higher wound retraction for both herbal-treated groups compared to the control (P < 0.05). Alcoholic extract of Jucá had antimicrobial activity against the microorganisms Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida krusei at different degrees, with MIC ranging from 250 to 16.625 μg/ml. Microscopic evaluation showed that the phytotherapic formulations contributed to better dermal wound healing through wound fibroplasia. The alcoholic extract of Jucá pods has great potential for wound healing in dogs and can be used in the development of commercially viable phytotherapic formulations.

Abstract
We evaluated the factors associated with the prevalence of antibodies against Brucella abortus in buffaloes in the municipality of Santarém, Western Pará, northern Brazil. The study was conducted on 60 farms, representing 25.8% of the total buffalo farms in the region. From those farms, a total of 426 buffaloes were sampled, males of any age and females more than 24 months of age, to avoid a false-positive reaction in the serological test due to vaccination. The Acidified Agglutination Serum Test was carried out on serum samples using B. abortus strain 1,119-3 as the antigen. Univariate and multivariate analysis were performed to investigate the association between brucellosis and potential risk factors. Of the 426 tested buffaloes, 29 were positive, resulting in an overall animal prevalence of antibodies against B. abortus at the animal level of 6.8% (4.6-9.6; 95% confidence interval). The herd level prevalence was 30% (18 of 60) and seroprevalence range within farms was from 0% to 100%. At the animal level, buffaloes raised in the floodplains tended (p = 0.06) to present a higher seroprevalence (9.70%) of antibodies against B. abortus than buffaloes raised in dry land (4.98%) and cows tended (p = 0.054) to have a higher seroprevalence than male buffaloes. Multivariate herd-level analysis revealed association between farm type and brucellosis seroprevalence (p = 0.015); dairy farms were two times more likely to have seropositive buffalo than beef farms. Our survey demonstrated a high farm seroprevalence of B. abortus in buffalo raised in an Amazonian ecosystem with positive animals found in one third of sampled farms.
