Although S. epidermidis is not usually pathogenic, patients with compromised immune systems are at risk of developing infection. These infections are generally hospital-acquired. [4] S. epidermidis is a particular concern for people with catheters or other surgical implants because it is known to form biofilms that grow on these devices. [5]
Populations of S. epidermidis have also been isolated from pustules of rosacea patients. However it is possible that they were moved by Demodex to areas that favour growth as Demodex has shown to transport bacteria around the face. [50] Current treatments include topical and oral antibiotics and laser therapy. [51]
Starting very early, research into biofilm formation in Staphylococcus epidermidis has served as a model for other staphylococci such as Staphylococcus aureus and other CoNS species. Moreover, data also showed that S. capitis have a strain (AYP1020) that researchers use to general genomic characteristics compared to S. epidermidis’ strain ...
Along with the bacteria C. acnes, the bacterial species Staphylococcus epidermidis (S. epidermidis) also takes a part in the physiopathology of acne vulgaris. The proliferation of S. epidermidis with C. acnes causes the formation of biofilms, which blocks the hair follicles and pores, creating an anaerobic environment under
The S. haemolyticus strain JCSC1435 genome contains a 2,685,015 bp chromosome and three plasmids of 2,300 bp, 2,366 bp, and 8,180 bp. The chromosome is comparable in size to those of S. aureus and S. epidermidis and contains a similar G+C content. In addition, a large proportion of the open reading frames (ORFs) are conserved across all three ...
Dispersin B is produced by Aggregatibacter actinomycetemcomitans, a Gram-negative oral bacterium, when it needs to detach and disperse adherent bacterial cells. [4] A. actinomycetemcomitans forms asymmetric biofilm lobed colonies that release single cells or small clusters of bacterial cells, which can attach to nearby surfaces, form new colonies, and enable the biofilm to spread.
EPSs are the construction material of bacterial settlements and either remain attached to the cell's outer surface, or are secreted into its growth medium. These compounds are important in biofilm formation and cells' attachment to surfaces. EPSs constitute 50% to 90% of a biofilm's total organic matter. [2] [4] [5]
A microbiologist examining cultures under a dissecting microscope. Medical microbiology, the large subset of microbiology that is applied to medicine, is a branch of medical science concerned with the prevention, diagnosis and treatment of infectious diseases.
