Streptococcus agalactiae, also known as Lancefield’s group B streptococcus (GBS), is a gram-positive facultative anaerobe. Found in around 30% of healthy adult gastrointestinal tracts and vaginas, it can cause severe infections. The bacterium is the leading cause of septicaemia, pneumonia and meningitis in neonates. Additionally, a recent study showed that neonates of GBS+ women have a different microbiota composition compared to GBS-, possibly leading to disease development later in life.

Eubacterium is a genus of gram-positive bacteria. They are one of the most abundant species in healthy colons and use lactate and acetate to produce butyrate, and 1,2 propanediol to produce propionate.

Depletion of Eubacterium rectale has been associated with high fat diets, colorectal cancer and ulcerative colitis. Species belonging to this genus are also involved in the metabolism of polyphenols - health-promoting metabolites, which can reduce incidence of carcinogenesis. Eubacterium rely on sources of resistant starches for survival.

S. mutans is a gram positive bacterium commonly found in the human oral cavity. It is known to promote dental caries. S. mutans has been shown to elicit inflammation by stimulating cytokine production in the dental pulp below caries. When this inflammation reaches the intestines, it can contribute to dysbiosis, breakdown of intestinal barrier structures and the infiltration of S. mutans immunogens into circulation. Antibodies against S. mutans have long been recognized as cross-reactive to human heart tissues and thus, suspected of playing a role in heart disorders.

Imbalanced bacteria are usually neither pathogenic nor beneficial to the host GI tract. Imbalances can occur when there are insufficient levels of beneficial bacteria and increased levels of commensal bacteria. Certain commensal bacteria are reported as dysbiotic at higher levels.

Streptococcus is a member of Gram-positive lactic acid-producing bacteria (LAB) that belonged to Firmicutes phylum. Many strains of Streptococcus are non-pathogenic and occur as commensal flora on the skin, the oral cavity, nasopharynx, upper respiratory tract, urogenital, and gastrointestinal tracts.

Higher abundance of S. salivarius and S. thermophilus (Firmicutes phylum) have been associated with a moderate to severe disease course in newly diagnosed ulcerative colitis (UC) patients.

These findings are in accordance with a study that showed that UC patients have significantly increased Streptococcus spp. and depletion of Bifidobacterium spp. Higher levels of Streptococcus spp. were also observed in patients with colorectal cancer compared to healthy controls. Administration of S. salivarius together with Bifidobacterium bifidum was shown to reduce the incidence of acute diarrhea and rotavirus shedding in infants. S. salivarius and S. thermophilus are also widely used in dairy products like yogurt and cheese.

Streptococcus thermophilus belongs to a group of bacteria called lactic acid bacteria.

Lactic acid bacteria are found in fermented foods such as yogurt and cheese. Streptococcus thermophilus are used as so-called "probiotics," the opposite of antibiotics. "Friendly" bacteria such as Streptococcus thermophilus can help us break down food, absorb nutrients, and fight off "unfriendly" organisms that might cause diseases such as diarrhea.

Streptozymes (NADase, DNase, streptokinase, streptolysin O, and hyaluronidase) are extracellular products, or exoantigens, of the streptococcus bacteria.

S stercoralis has a complex lifecycle that begins with maturation to the infective filariform larva in warm, moist soil. The larvae subsequently penetrate exposed skin and migrate hematogenously to the lungs, from where they ascend the bronchial tree and are swallowed. Once in the small intestine, filariform larva matures into the adult worms that burrow into the mucosa. Gravid female worms produce eggs that develop into noninfectious rhabditiform larvae in the gastrointestinal tract and are eventually released in the stool. The time from dermal penetration to appearance of Strongyloides in stool samples is approximately 3 to 4 weeks.
