Streptococcus thermophilus, also known as Streptococcus salivarius subsp. thermophilus, is commonly used in the dairy industry. Along with Lactobacillus bulgaricus it serves as a starter in the production of yogurt. Streptococcus comes from a Greek term meanings easily bent or twisted, which refers to the way the bacterium is grouped in chains that resemble a string of beads.  Thermophilus means love of heat and refers to the bacteria’s ability to thrive at high temperatures. It is from the genus Streptococcus which also contains many harmful bacteria such as Streptococcus pyogenes and pneumoniae and from the order Firmicutes, which are the most common bacteria in our gut. A number of studies have been conducted to test its health benefits. It is one of the bacteria that has been shown to specifically help ulcerative colitis.
