Understanding Gram-Positive Cocci in Clusters: Key Features, Clinical Relevance, and Diagnosis Gram-positive cocci in clusters represent a fascinating and clinically significant group of bacteria with unique structural, biological, and medical characteristics. These round-shaped microorganisms, arranged in chains or clusters (also called “lace or grape-like clusters”), belong primarily to genera such as Streptococcus, Enterococcus, and Lancefield group streptococci. Understanding their morphology, staining behavior, and clinical importance is essential for microbiologists, clinicians, and medical professionals. --- ### What Are Gram-Positive Cocci in Clusters?
