Overview

Jeotgalicoccus coquinae is a species of bacteria classified within the family Staphylococcaceae. Like other members of its genus, it is gram-positive and composed of spherical, coccoid cells. The species is primarily discussed in microbiological and taxonomic literature rather than in clinical contexts.

Characteristics

Cells of J. coquinae are round (cocci) and, when viewed microscopically, appear as single cells or small groups rather than long chains. The gram-positive cell wall gives a characteristic staining pattern used for initial laboratory identification. Colony appearance, biochemical reactions and growth conditions are used alongside molecular methods to distinguish it from related species.

Physiology and ecology

Species in the genus Jeotgalicoccus are often halotolerant, meaning they can tolerate elevated salt concentrations, and many isolates come from saline or food‑processing environments. Although specific traits can vary between species, these bacteria generally grow under a range of environmental conditions and contribute to the microbiota of foods, animals, and marine or coastal habitats.

History and isolation

The genus name recalls traditional salted fermentations from which early members were recovered; subsequent sampling has found related organisms in diverse niches. Individual species descriptions are typically based on a combination of culture characteristics and genetic sequencing, especially 16S rRNA gene comparisons, to place an isolate within Jeotgalicoccus and to define a new species.

Relevance and uses

J. coquinae and its relatives are primarily of interest for understanding microbial diversity, food microbiology, and salt‑adaptation mechanisms. They are not commonly associated with human disease; most investigations focus on ecology, taxonomy, or possible applications in biotechnology related to salt‑tolerant enzymes and metabolites.

Distinguishing features and identification

  • Gram reaction: gram-positive staining.
  • Cell shape: coccoid, spherical morphology.
  • Taxonomy: member of Staphylococcaceae, separate genus from Staphylococcus based on genetic and phenotypic criteria.
  • Laboratory methods: combination of culture tests and molecular sequencing is used for reliable identification.
