Abstract: Salmonella enterica serovar Typhimurium is a non-spore-forming, Gram-negative bacterium
considered a major zoonotic pathogen in poultry and public health. It is characterized by the
complexity of its antimicrobial resistance (AMR) mechanisms, which arise from genetic
processes – such as horizontal gene transfer – and intrinsic structural and enzymatic adaptations.
Under the One Health approach, its dissemination impacts animal, human, and environmental
health, being particularly prevalent in foodborne disease outbreaks. Given the problem of
conventional antimicrobial resistance and the One Health impact, the prospecting of plant
derived bioactive compounds has intensified as a promising alternative strategy. Thus, the main
objective of this study was to analyze and evaluate the antimicrobial effect of the plant extracts
from "jucá" or "ironwood" (Libidibia ferrea) and "Arabica coffee" (Coffea arabica) on resistant
S. Typhimurium strains isolated from chicken carcasses across different regions of Brazil. The
antimicrobial activity of the L. ferrea pod extract (at concentrations in mg/ml: 31.25; 15.63;
7.81; 3.90; 1.95; 0.97; 0.48; 0.24) and the C. arabica leaf extract (at concentrations in mg/ml:
30; 15; 7.5; 3.75; 1.87; 0.93; 0.46; 0.23) was evaluated on seventeen S. Typhimurium strains
using the broth microdilution method to prepare the different concentrations, followed by the
determination of the Minimum Bactericidal Concentration (MBC). Each strain was analyzed in
triplicate, and the association between the different plant extract concentrations and bacterial
growth was analyzed using a descriptive method. For the L. ferrea plant extract, the absence of
growth (MBC) was observed at the following concentrations: 7.81 mg/ml (1 strain – 5.88%),
15.63 mg/ml (14 strains – 82.35%), and 31.25 mg/ml (2 strains – 11.76%). For the C. arabica
plant extract, the MBC was 30 mg/ml for 13 of the 17 strains evaluated (76.47%), while four
strains (23.53%) did not respond to any of the tested concentrations, showing an MBC greater
than 30 mg/ml. Based on these results, it was observed that S. Typhimurium showed a dose
dependent response (decreased or absent growth) as the concentration of L. ferrea and C.
arabica extracts increased. These results indicate that the extracts of L. ferrea (pods) and C.
arabica (leaves) demonstrated antimicrobial potential against the tested strain. The L. ferrea
extract stood out due to its higher efficacy, showing bactericidal activity at the lowest
concentration evaluated, positioning both compounds as promising alternatives in the fight
against global antimicrobial resistance.2025-12-12T00:00:00ZUltrassonografia na avaliação da cavidade celomática em aves – Revisão de literaturahttps://repositorio.ufu.br/handle/123456789/483042026-02-14T06:21:34Z2025-12-11T00:00:00ZTitle: Ultrassonografia na avaliação da cavidade celomática em aves – Revisão de literatura
Abstract: The use of ultrasonography as a complementary diagnostic tool for evaluating the coelomic
cavity in birds has helped many veterinarians to guide their diagnoses more precisely, as well
as to improve clinical management and treatment. Nevertheless, the vast diversity among
avian species makes it difficult to obtain comprehensive information about which species are
treated in each region, in addition to the anatomical limitations of these animals and the
technical challenges inherent to the ultrasonographic equipment itself. The main indications
for this examination include the investigation of masses and soft tissue alterations,
organomegaly, reproductive tract abnormalities, and the identification of free fluid. This study
aims to highlight the advantages and disadvantages of coelomic ultrasonography, imaging
windows and positioning, ultrasonographic anatomy, main findings involving the celom, and
different pathological conditions, focusing on bird species commonly treated in Brazilian
