The term is not a formal taxonomic category, but is used to discuss phenotypic traits that echo the archetype of Gram-negative organisms.
Staining and envelope features: Gramnegativelike properties may include a thin or reduced peptidoglycan layer, an outer
Interpretation and limitations: The Gram stain is a phenotypic assay influenced by cell age, growth phase, and
Context and use: In research and clinical microbiology, Gramnegativelike is used to describe unusual or intermediate
