13. Isolamento, investigação química e avaliação do potencial antibiótico, antibiofilme e anti-trichomonas vaginalis de fungos associados a organismos marinhos da costa sul do Brasil / Isolation, chemical investigation and evaluation of antibiotic, antibiofilm and anti-Trichomonas vaginalisactivities of fungi associated to marine organisms from south brazilian coast
Fungi isolated from marine organisms attract the interest of many researchers around the world, since they produce differentiated secondary metabolites due to the environmental conditions to which these organisms are subjected. Several biological activities have been reported for these compounds, mainly as antitumoral, antibacterial and, antiprotozoal. The i

15. Evaluation of different detection methods of biofilm formation in the clinical isolates
BACKGROUND: Microorganisms growing in a biofilm are associated with chronic and recurrent human infections and are highly resistant to antimicrobial agents. There are various methods to detect biofilm production like Tissue Culture Plate (TCP), Tube method (TM), Congo Red Agar method (CRA), bioluminescent assay, piezoelectric sensors, and fluorescent microsc

16. Evaluation of the synergistic potential of vancomycin combined with other antimicrobial agents against methicillin-resistant Staphylococcus aureus and coagulase-negative Staphylococcus spp strains
Methicillin-resistant Staphylococcus aureus (MRSA) and coagulase-negative Staphylococcus spp (CNS) are the most common pathogens that cause serious long term infections in patients. Despite the existence of new antimicrobial agents, such as linezolid, vancomycin (VAN) remains the standard therapy for the treatment of infections caused by these multidrug-resi

17. Avaliação do perfil de resistência a antimicrobianos de bactérias gram-negativas isoladas nas águas do Arroio Dilúvio / Evaluation of antimicrobial resistance the profile of gram-negative bacteria isolated from dilúvio gully waters
The Dilúvio is part of an important watershed in the city of Porto Alegre, RS, having 17.605m of extension rising in the city of Viamão and flowing into Guaíba Lake receiving all kind of waste resulting from pluvial, domestic and hospital wastewater. Thus, the gully receives a diverse microbial population, some of these microorganisms may exhibit resistan

19. PRELIMINARY PHYTOCHEMICAL PROFILE AND EVALUATION OF GASTROPROCTIVE ACTIVE OF HIDROALCOHOLIC EXTRACT, FRACTIONS AND SUBFRACTIONS OF KALE LEAVES (Brassica oleracea L. var. acephala DC.) / Estudo do perfil fitoquímico e avaliação da atividade gastroprotetora do extrato hidroalcoólico, frações e subfrações das folhas de couve: Brassica oleracea L. var. acephala DC.
P opular reports indicate that kale, Brassica oleracea L. var. acephala DC., when taken while fasting, in the form of a juice, relieves the symptoms of gastric disorders. Studies show that some compounds present in plants of this genus exhibit antioxidant, wound healing, antimicrobial, anti-inflammatory and anticancer activity. Thus, this study investigates

20. The evaluation of bacteriology in perianal abscesses of 81 adult patients
OBJECTIVE: Treatment of perianal abscesses requires prompt surgical drainage and antimicrobial therapy. However, we should encourage the selective use of antimicrobial agents on a case-by-case basis, especially because there is no evidence that uncomplicated perianal abscesses can be safely treated only with drainage. For this reason, it is important to iden
