Streptococcus suis strain HN136

Streptococcus suis strain HN136 is a Gram-positive, cocci-shaped bacterium that typically forms chains, pairs, and singles. This strain is classified as a facultative anaerobe, indicating its ability to grow in both the presence and absence of oxygen. S. suis HN136 is non-motile and lacks flagella, which is consistent with its habitat preferences. This strain exhibits an optimal growth temperature of 37°C, placing it within the mesophilic temperature range. It has a single replicon and one membrane, characteristic of many bacteria in the Streptococcus genus. S. suis HN136 is free-living and has been identified in various hosts, including humans (Homo sapiens), other metazoans, the zebrafish (Danio rerio), and pigs (Sus scrofa). The health impacts associated with S. suis HN136 are notable, as this strain is linked to a range of serious conditions such as endocarditis, meningitis, septicaemia, endophthalmitis, sepsis, arthritis, and spinal canal infections, among others. These health effects can lead to severe complications, highlighting the bacterium's pathogenic potential in humans and other hosts. Understanding the ecological role and pathogenic potential of Streptococcus suis strain HN136 can provide insights into its interactions with various hosts and the environments it inhabits. This highlights the importance of monitoring such organisms in both veterinary and human health contexts, given their implications for public health and disease management strategies.
