Streptococcus thermophilus strains are a gram-positive, lactic-acid probiotic that helps to make some of your favourite foods, including yogurt. Yes, thanks to Streptococcus thermophilus' impressive digestive abilities yogurt can get that distinctive flavour and texture so many adore.
Streptococcus thermophilus is a Gram positive bacterium widely used in dairy fermentations for the production of yogurt and cheese. In contrast with other lactic acid bacteria, the probiotic status of S. thermophilus remains still questioned.
STREPTOCOCCUS | Introduction
It grows symbiotically with Lactobacillus delbrueckii subsp. bulgaricus during fermentation to produce lactic acid and acetaldehyde, which is responsible for the characteristic yogurt flavor. In cheeses, S. thermophilus contributes to milk acidification and to flavor during ripening.
Yogurt is made when heated milk is combined with bacteria, specifically Lactobacillus bulgaricus and Streptococcus thermophilus, and left to sit for several hours at a warm temperature (110-115°F).
Streptococcus thermophilus is among the species commonly used in the dairy industry, mainly in the fermentation of yogurt and several cheese varieties, contributing to the desirable organoleptic characteristics of the final product [4, 5].
Streptococcus thermophilus is widely used as a starter culture in cheese, yogurt, and other cultured dairy products. Due to its commercial importance, the physiological, ecological, and metabolic properties of S. thermophilus have been well described.
The presence of Streptococci in drinking water indicates fecal contamination. Food sources with high risk of Streptococcal contamination include milk and dairy products, eggs, steamed lobster, ground ham, potato salad, custard, rice pudding and shrimp salad.
bulgaricus to produce lactic acid, which acts on milk protein to give yoghurt its texture and its characteristic acidic taste. Other bacteria found in yoghurt are Lactobacillus acidophilus or casei, Streptococcus salivarius subsp. thermophilus and Bifidobacterium bifidus.
All yoghurt contains live bacterial cultures, which ferment milk to make yoghurt, but only some types of yoghurt have added probiotics (bacteria that have a proven health benefit).
But kefir is typically less thick and more tangy. Kefir contains more probiotics than any yogurt. With up to 61 different strains of microbes, it can be an excellent source of probiotics. People use specific clusters of microbes called kefir grains to ferment the milk.
[8] Most probiotics are Gram-positive bacteria that belong to the genera Lactobacillus or Bifidobacterium. [9] Studies based on the use of the intestinal probiotics Lactobacillus rhamnosus GG,[10] Lactobacillus reuteri, and Bifidobacterium[11] have each reported achieving reduced levels of Streptococcus mutans.
Avoid spicy foods or acidic foods such as orange juice. Gargle with warm salt water. For older children and adults, gargling several times a day can help relieve throat pain. Mix 1/4 teaspoon (1.5 grams) of table salt in 8 ounces (237 milliliters) of warm water.
Invasive group A streptococcal infections occur when the bacteria gets past the defenses of the person who is infected. This may occur when a person has sores or other breaks in the skin that allow the bacteria to get into the tissue.
Group A streptococci are bacteria commonly found in the throat and on the skin. People may carry GAS in the throat or on the skin and not become ill.
Group A Streptococcus (group A strep) is a type of bacterium (germ) that can be found in the nose and throat and on the skin. These bacteria might be present and not cause any illness, or they can infect different parts of the body and cause disease that can range from mild to severe.
Strep throat treatment includes antibiotics. An antibiotic is a type of medicine that kills the bacteria that cause an infection. Penicillin and amoxicillin are common antibiotics healthcare providers use to treat strep throat.
In the case of Greek yogurt, the live cultures are the active bacteria S. thermophilus (St) and L. bulgaricus (Lb), which ferment the milk to make its characteristic tangy taste.
Greek yoghurt is generally considered the most nutritious option when it comes to yoghurts. Due to the way it is made, it is naturally higher in protein, which makes it a great addition to breakfast, leaving you feeling satisfied throughout the morning.
Yogurt is also high in protein, vitamins, and minerals, so yogurt products with live and active probiotics make a great addition to any balanced diet. People can find yogurt that contains L. acidophilus in supermarkets and health stores, with popular brands including Chobani, Yoplait, Skyr, and Noosa.

Turmeric Milk with Honey – turmeric milk has many health benefits including antibacterial properties that may be beneficial against streptococcus bacteria causing strep throat infections.
It is most common in children 5 through 15 years old. It is very rare in children younger than 3 years old. Adults who are at increased risk for strep throat include: Parents of school-aged children.
Supporting your health foundations, like diet, exercise, and sleep, is the first step toward getting rid of bad bacteria in the gut. If that doesn't solve the problem by itself, then probiotics should be the next step to crowd out harmful bacteria and restabilize the microbiome.
