A case of facial cellulitis complicated by regional thrombophlebitis and septicemia is reported in a 6 year-old girl. Streptococcus sanguis, a bacterial agent, unusually responsible for cellulitis, was isolated from 5 blood cultures. This child had no immunosuppression or endocarditis or dental infection. She had been previously given a non-steroidal anti-inflammatory agent, which was potentially responsible for the diffusion of infection.

Background: Recently, products with antibacterial properties derived from medicinal plants have increased as an alternative to conventional drugs. Thus, this study aimed to formulate and evaluate the antibacterial activity of an experimental gel based on Grindelia tarapacana essential oil in a bacterial consortium.
Material And Methods: The composition of the essential oil (EO) was determined using gas chromatography-mass spectrometry (GC-MS).

Background And Aim: Streptococci, mainly mutans streptococci, are known as the causative microbes of dental caries, but there is limited clarity about their impact on the tooth level and the distribution of streptococci species in different dentition stages. This study evaluates the distribution of streptococci species in primary and permanent teeth in children and adolescents with caries.
Materials And Methods: The study population consisted of two groups: subjects with caries in primary teeth aged 2-5 years and adolescents with caries in permanent teeth aged 12-15 years.

Mucins are key components of innate immune defense and possess remarkable abilities to manage pathogenic microbes while supporting beneficial ones and maintaining microbial homeostasis at mucosal surfaces. Their unique properties have garnered significant interest in developing mucin-inspired materials as novel therapeutic strategies for selectively controlling pathogens without disrupting the overall microbial ecology. However, natural mucin production is challenging to scale, driving the need for simpler materials that reproduce mucin's bioactivity.

Physicochemical modifications of biomaterials have been proposed to overcome bone integration impairment and microbial infections. The magnesium (Mg) incorporation on dental implant surfaces has shown positive results in bone-to-implant contact and in the reduction of microbial colonization. Here, we explored the potential of using different Mg precursors to synthesize coatings via plasma electrolytic oxidation (PEO) on commercially pure titanium (cpTi), aiming to optimize the surface and biological properties.
