Streptococcus pneumoniae strain GPSC13

Streptococcus pneumoniae strain GPSC13 is a Gram-positive bacterium characterized by its cocci shape and a typical arrangement in chains or pairs. This strain is non-motile and lacks flagella. As a facultative anaerobe, it can thrive in both aerobic and anaerobic environments, with an optimal growth temperature of 30°C, placing it within the mesophilic temperature range. S. pneumoniae GPSC13 is notable for its pathogenicity in humans, causing a wide array of health issues, including pneumonia, bacteremia, meningitis, and various forms of infections such as sepsis and otitis media. Its ability to affect multiple hosts extends beyond humans (Homo sapiens) to include domesticated animals such as chickens (Gallus gallus), guinea pigs (Cavia), and other small mammals like Meriones unguiculatus and Chinchilla. This adaptability to different hosts underlines its ecological versatility. With a single replicon and one membrane, GPSC13 exists as a free-living organism, which contributes to its capacity to colonize diverse environments. The strain's involvement in severe health conditions, particularly invasive pneumococcal disease (IPD), highlights its significant public health impact. Understanding the ecological and biological traits of S. pneumoniae GPSC13 is crucial for developing effective strategies for prevention and treatment of the infections it causes, especially in vulnerable populations.
