Streptococcus pneumoniae strain GPSC136

Streptococcus pneumoniae strain GPSC136 is a Gram-positive cocci bacterium characterized by its arrangement in chains and pairs. This strain is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. It has no mobility and does not possess flagella. Its optimal growth temperature is 30°C, placing it within the mesophilic temperature range. GPSC136 has a single replicon and a single membrane, indicating a relatively simple cellular structure. This bacterium is free-living, with known hosts including Homo sapiens (humans), Gallus gallus (chickens), Cavia (guinea pigs), Meriones unguiculatus (gerbils), and Chinchilla. The strain is associated with a range of health effects in humans, including bacteremia, pneumonia, meningitis, and various infections such as sepsis, cellulitis, and otitis media. It is particularly noted for causing community-acquired pneumonia (CAP) and invasive pneumococcal disease (IPD). Other associated conditions include acute otitis media, bronchitis, and septic thrombosis of the cavernous sinus. The pathogenicity of S. pneumoniae strain GPSC136 primarily affects humans, highlighting its role as a significant human pathogen. This strain's ability to infect multiple hosts and its range of pathogenic effects suggest it occupies a versatile ecological niche, adapting to various environments and hosts while contributing to its relevance in public health.
