Gram-positive bacteria are capable of causing serious and sometimes fatal infections in newborn infants. [19] Novel species of clinically relevant gram-positive bacteria also include Catabacter hongkongensis, which is an emerging pathogen belonging to Bacillota. [20]
A Gram stain of mixed Staphylococcus aureus (S. aureus ATCC 25923, gram-positive cocci, in purple) and Escherichia coli (E. coli ATCC 11775, gram-negative bacilli, in red), the most common Gram stain reference bacteria. Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups ...

Bacillota (synonym Firmicutes) is a phylum of bacteria, most of which have gram-positive cell wall structure. [2] The renaming of phyla such as Firmicutes in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature.
Listeria is a genus of bacteria that acts as an intracellular parasite in mammals. As of 2024, 28 species have been identified. [1] [2] [3] The genus is named in honour of the British pioneer of sterile surgery Joseph Lister. Listeria species are Gram-positive, rod-shaped, and facultatively anaerobic, and do not produce endospores. [4]
The Actinomycetota (or Actinobacteria) are a diverse phylum of Gram-positive bacteria with high GC content. [4] They can be terrestrial or aquatic. [5] They are of great importance to land flora because of their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up ...
Clostridium is a genus of anaerobic, Gram-positive bacteria.Species of Clostridium inhabit soils and the intestinal tracts of animals, including humans. [1] This genus includes several significant human pathogens, including the causative agents of botulism and tetanus.
In 2014, two thermophilic, Gram-positive, rod-shaped, non-spore-forming bacteria (strains KI3 T and KI4 T) isolated from geothermally heated biofilms growing on a tumulus in the Kilauea Iki pit crater on the flank of Kilauea Volcano (Hawai'i) were proposed as representatives of new species based on 16s rRNA phylogeny.
