| Description | Granulicatella is a gram-positive, cocci-shaped microbe that thrives in mesophilic temperatures, categorized as a chemoheterotroph, and can be found in various body sites, including the oral cavity, respiratory tract, and urogenital tract, across all possible species, and is typically a facultative anaerobe. The gram-positive stain is indicative of a thick peptidoglycan layer in its cell wall, providing resistance to environmental stresses. As a cocci-shaped microbe, Granulicatella has a spherical shape, allowing it to maintain a large surface area-to-volume ratio, facilitating nutrient uptake and interactions with its environment. Its mesophilic temperature preference suggests that it grows best in moderate temperatures, between 20-45°C, making it well-suited to inhabit the human body. As a chemoheterotroph, Granulicatella relies on organic compounds for energy and carbon, obtaining these nutrients from its host or environment. Its ability to inhabit various body sites is likely due to its adaptability and ability to form biofilms, allowing it to persist in diverse environments. As a facultative anaerobe, Granulicatella can grow in the presence or absence of oxygen, although it may prefer microaerophilic conditions. Granulicatella has been implicated in various infections, including endocarditis and bacteremia, and its ability to form biofilms and persist in the human body makes it a significant concern in healthcare settings. The presence of Granulicatella in the oral cavity has also been linked to periodontal disease, highlighting the importance of oral hygiene in preventing the spread of this microbe. |
