This study aimed to evaluate the antimicrobial activity of clove (Syzygium aromaticum), citronella (Cymbopogon winteranius) and melaleuca (Melaleuca alternifolia) essential oils (EOs) on CoPS. Of the 67 cerumen samples collected, 17 CoPS strains were isolated. Using the microdilution method in a 96-well plate, EOs were added at a maximum concentration of 10% and minimum of 0.04%. It is concluded that the EOs of clove and citronella demonstrate antimicrobial activity against strains of CoPS isolated from canine external otitis. At the concentrations used, melaleuca essential oil did not show any bacteriostatic or bactericidal effects.
This study aimed to evaluate the microbiological contamination of the different sectors of a university veterinary hospital, the efficiency of the sanitation procedures performed, and the resistance to antimicrobials and disinfectants. Fourteen environmental samples and seven swab samples were collected from procedure tables of the different sectors. During analysis, the following microorganisms were found: bacterial species Rothia spp., coagulase-negative Staphylococcus spp., Staphylococcus aureus, and Enterococcus spp. and zygomycete fungi (could not be classified in genus due to the absence of reproductive structures) and other fungal species Cladosporium spp., Epicoccum spp., Drechslera spp., Scopulariopsis spp., and Penicillium spp. The bacterial species were submitted to a sensitivity assessment of the antimicrobials used in routine prescription. Rothia spp. and S. aureus were resistant only to erythromycin (15 µg), coagulase-negative Staphylococcus spp. were resistant to erythromycin (15 µg) and sulfazotrim (25 µg), and Enterococcus spp. were resistant to ampicillin (10 µg). For the effectiveness test of disinfectants, the products used to sanitize hospital surfaces were tested. All microorganisms in this study were resistant to 1% sodium hypochlorite solution. Rothia spp. and Enterococcus spp. were resistant to 70% ethyl alcohol. The best results were found using pure sodium hypochlorite and benzalkonium chloride, pure and diluted to 20%, which showed a bactericidal effect against all tested microorganisms. These data are relevant for knowledge of the hospital microbiota at the intersection of possible cases of hospital infections.
Diante de um cenário inusitado, apresentado pela pandemia da Covid-19, as formas de abordagem e as metodologias educacionais no ensino superior tiveram que ser repensadas e adaptadas em tempo recorde. O objetivo deste estudo foi avaliar a experiência da aplicação remota da disciplina de Inspeção de Produtos de Origem Animal do curso de medicina veterinária da Universidade Federal da Fronteira Sul, ministrado de setembro de 2020 a janeiro de 2021. Foram 17 semanas com aulas síncronas e/ou assíncronas, com aplicação de metodologias ativas e atividades individuais ou em grupos. Os alunos foram questionados durante e ao final do curso sobre as tarefas e acompanhamento da disciplina. Na primeira metade da disciplina, todas as atividades propostas aos estudantes tiveram mais de 50% de aceitação. Ao final as respostas variaram mais. Mas 62,1% dos alunos responderam que as aulas remotas geraram conexão entre o aluno e o professor, enquanto que 27% disseram que não e 10,8% não souberam responder. Esta experiência, de certa forma, teve uma aceitação positiva as novas abordagens e plataformas digitais oferecidas, bem como superado os desafios e dificuldades pessoais às propostas diferentes.
