The term "Bacillus of Scheurlein" refers to a specific strain of bacteria known as Bacillus scheurlei. Bacillus is a genus of rod-shaped, gram-positive bacteria that belong to the phylum Firmicutes. These bacteria are characterized by their ability to form endospores, which are dormant structures that help them survive in harsh conditions.
The Bacillus of Scheurlein, or Bacillus scheurlei, was first isolated and identified by microbiologist Georges Scheurlein in the early 20th century. It primarily inhabits the human intestinal tract, where it plays a role in maintaining the balance of the microbial community. It is considered a commensal, which means it normally coexists with its host without causing harm.
Although Bacillus of Scheurlein is generally harmless to healthy individuals, it can become opportunistic and cause infections in individuals with weakened immune systems or underlying health conditions. In such cases, it can lead to various infections, including bacteremia, endocarditis, and septicemia.
Identification of Bacillus of Scheurlein typically involves laboratory tests, such as Gram staining and biochemical tests. These tests help differentiate it from other species of Bacillus and confirm its presence in clinical samples.
In summary, the Bacillus of Scheurlein is a strain of bacteria that resides in the human intestinal tract and is generally harmless. It forms endospores and can cause infections in individuals with compromised immune systems.
