“…Type strains are descendants of the original isolates that were defined in species and subspecies descriptions and therefore, play a crucial role in defining the phylogenomic and taxonomic space of Bacteria 30 . Therefore, we also sequenced the genome of “type strain” of S. epidermidis MTCC3382(T), which was originally isolated from human nares 31 . The draft genome features and assembly stats of S. epidermidis MTCC3382(T) and RESE genomes are shown in Table 1 and Table S1 , respectively.…”

Staphylococcus epidermidis is a major human associated bacterium and also an emerging nosocomial pathogen. There are reports of its association to rodents, sheep and plants. However, comparative and evolutionary studies of ecologically diverse strains of S. epidermidis are lacking. Here, we report the whole genome sequences of four S. epidermidis strains isolated from surface sterilized rice seeds along with genome sequence of type strain. Phylogenomic analysis of rice endophytic S. epidermidis (RESE) with “type strain” unequivocally established their species identity. Whole genome based tree of 93 strains of S. epidermidis revealed RESE as distinct sub-lineage which is more related to rodent sub-lineage than to majority of human lineage strains. Furthermore, comparative genomics revealed 20% variable gene-pool in S. epidermidis, suggesting that genomes of ecologically diverse strains are under flux. Interestingly, we were also able to map several genomic regions that are under flux and gave rise to RESE strains. The largest of these genomic regions encodes a cluster of genes unique to RESE that are known to be required for survival and stress tolerance, apart from those required for adaptation to plant habitat. The genomes and genes of RESE represent distinct ecological resource/sequences and provided first evolutionary insights into adaptation of S. epidermidis to plants.

“…In 1974,Kloos and Schleifer introduced the biochemical classification scheme for the differentiation of Staphylococcus species, on which current bio typing schemes are based [15]. Consequently, S. epidermidis became recognised as the major cause of all CNS infections except those of the urinary tract [15,[16][17], with Staphylococcus saprophyticus was found to account for 80% (12/15) of female urinary tract infections [18] . The original Kloos and Schleifer scheme described 11 different staphylococcal species [19].…”

Staphylococcus epidermidis is a resilient microbe distinguished by its immobile, Gram-positive spherical cells that aggregate in clusters resembling grape clusters. Biochemical examinations reveal a faintly positive outcome in the nitrate reductase test for this microbe. It generates urease while lacking oxidase production. S. epidermidis possesses a transferrin-binding protein that facilitates the acquisition of iron from transferrin. The formation of biofilms on plastic devices plays a pivotal role in the pathogenicity of S. epidermidis and its connection to acne. This adaptable bacterium is frequently encountered as a nosocomial and commensal pathogen, recognized for its opportunistic behavior and its global impact on infections, primarily contracted within healthcare facilities. It displays a remarkable ability to establish strong biofilms on various surfaces, contributing to infections linked to catheters and heart valve implants. The transmission of the bacterium is easily facilitated through the contamination of the skin of hospital visitors and healthcare personnel.

“… Staphylococcus epidermidis was distinguished from Staphylococcus aureus in 1884 by Friedrich Rosenbach, and the name Staphylococcus albus was originally proposed for it ( albus meaning ‘white’ in Latin and staphyle meaning ‘cluster’ in Greek) [1]. In 1908, the name Albococcus epidermidis ( epiderma , meaning the outer skin; epidermidis , of the epidermis) was further proposed by Winslow and Winslow [2], who emphasized the importance of the following characteristics in classification of the Coccaceae into genera: Gram stain, pigmentation, breakdown of sugars and the ability to cause disease. At the time, the two genera Aurococcus (orange) and Albococcus (white) were defined as differing only in pigmentation, as both were Gram-positive, irregularly grouped cells, parasitic, and able to produce acid from sugars.…”

Staphylococcus epidermidis is the most abundant commensal bacterium of human skin. Despite protecting us from foreign invaders, S. epidermidis itself exploits human vulnerability when given the opportunity. Such opportunities arise when patients are immunocompromised or when biomedical implants present an opportunity to colonize the surface and form biofilms. S. epidermidis is one of the most frequently isolated organisms from implanted devices and from bloodstream infections. However, S. epidermidis infections are often recalcitrant to antibiotics because of biofilm-associated antibiotic tolerance. Furthermore, the emergence and spread of nearly pan-resistant strains is a considerable health concern. Symptoms can be subclinical, making diagnosis challenging, and treatment with antibiotics is inefficient. For now, infection prevention remains the best strategy available.
