Within mammalian cells, diverse endocytic mechanisms, including phagocytosis, pinocytosis, and receptor-mediated endocytosis, serve as gateways exploited by many bacterial pathogens and toxins. Among these, caveolae-mediated endocytosis is characterized by lipid-rich caveolae and dimeric caveolin proteins. Caveolae are specialized microdomains on cell surfaces that impact cell signaling.

is considered an emerging novel pathogenic cause of severe skin infections. The organism is a gram-negative motile bacillus commonly found in marine environments. While the more common causes of skin and soft tissue infections include , beta-hemolytic Streptococci, and/or have also been isolated in rare cases.

In the literature, is documented as a causative agent of infective endocarditis, demonstrated by blood cultures in only four other cases, representing an extremely rare circumstance. Here, we describe a case of infective endocarditis due to in a young patient known with a bicuspid aortic valve and associated with a sigmoid precancerous polyp.

The cariogenicity of Streptococcus mutans relates to its ability to form biofilms on dental surfaces. The aim of this work was to develop a flowcell system compatible with time-lapse confocal microscopy to compare the adhesion and accumulation of S. mutans cells on surfaces in unsupplemented media against media containing sucrose or sucralose (a non-metabolized sweetener) over a short period of time.
