26. Microbial profile of symptomatic pericoronitis lesions: a cross-sectional study
Abstract Objective: The microbial composition of pericoronitis (Pc) is still controversial; it is not yet clear if the microbial profile of these lesions is similar to the profile observed in periodontitis (Pd). Therefore, the aim of the present study was to describe the microbial profile of Pc lesions and compare it directly with that of subjects with Pd.

28. Extended Spectrum Beta-Lactamase Production and Biofilm Formation in Salmonella Serovars Resistant to Antimicrobial Agents
ABSTRACT Antimicrobial resistance is a serious public health problem and Salmonella spp. is highly resistant to antimicrobial agents. Biofilms are important in the food industry due to their formation on products, utensils, and surfaces and the difficulty in their removal. The objective of this study was to assess extended spectrum beta-lactamase (ESBL) prod

30. Inhibition and Eradication Effect of Javanese turmeric (Curcuma xanthorrhiza Roxb.) Extract Against Mature Phase Biofilm of Candida albicans
Abstract Objective: To analyze the potency of Javanese turmeric extract in inhibiting and eradicating the mature phase of C. albicans biofilm. Material and Methods: C. albicans ATCC 10231 was cultured in Sabouraud Dextrose Broth on a 96-well plate and was incubated at 37ºC. To analyze its inhibitory effect, C. albicans cultures were incubated for 1.5 hour

31. Antibacterial and Cytotoxic Potential of a Brazilian Red Propolis
Abstract Objective: To evaluate in vitro the effect of a red propolis ethanolic extract (RPE) in the prevention of growth of a cariogenic biofilm and its cytotoxic potential. Material and Methods: Minimum inhibitory and bactericidal concentrations (MIC and MBC) of RPE against Streptococcus mutans and Lactobacillus casei were determined. The cytotoxic poten

32. Antifungal activity of some Sternbergia taxa: effects on germ tube and biofilm formation
Natural products are rapidly becoming the primary sources of novel antimicrobial agents, as resistance to existing antimicrobial agents is increasing. Apart from determining the antimicrobial activity of natural products, it is also important to understand their effects on the virulence factors of microorganisms. This study aimed to determine the antimicrobi

34. Additive manufacturing of titanium alloy could modify the pathogenic microbial profile: an in vitro study
Abstract Additive manufacturing (AM) is an emerging process for biomaterials and medical devices. Direct Laser Metal Sintering (DLMS) is an AM technique used to fabricate Ti–6Al–4V implant materials with enhanced surface-related properties compared with wrought samples; thus, this technique could influence microbial adsorption and colonization. Therefore

35. Subgingival bacterial microbiota associated with ovine periodontitis
RESUMO: Periodontite é a resposta inflamatória de um hospedeiro suscetível causada por complexa microbiota, composta predominantemente por bactérias anaeróbias Gram-negativas. Com o objetivo de caracterizar a microbiota bacteriana subgengival associada à periodontite ovina foi realizada a reação em cadeia da polimerase (PCR) de amostras de biofilme s

36. Does subgingival bacterial colonization differ between implants and teeth? A systematic review
Abstract The aim was of this study was to determine the current weight of evidence for the existence of specific differences between the microbiota of healthy teeth and healthy implants, or of teeth with periodontitis and implants with peri-implantitis. A systematic review was conducted according to the PRISMA statement. The MEDLINE, EMBASE and Cochrane data
