# TODO (IMPORTANT): write a Email to Holger, say the short sequencing of HD5_2 is not correct, since the 3 datasets! However, the MTxxxxxxx is confirmed not in K5 and K6!
TODO: variant calling needs the short-sequencing, they are not dorable without the correct short-reads! resequencing? It is difficult to call variants only from long-reads since too much errors in long-reads!
#TODO: check the MT sequence if in the isolates, more deteiled annotations come late!
#II. Comparing the results of Trycycler with Unicycler.
#III. Eventually add the plasmids assembled from unicycler to the final results. E.g. add the 4 plasmids to K5 and K6

Background of 1585v and 1585

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8346721/ S. epidermidis 1585 is known to be biofilm-negative in laboratory media, but to form biofilm in the presence of human serum.

In contrast, S. epidermidis 1585 v is a variant derived from strain 1585 in which, due to a chromosomal re-arrangement, a 460 kDa isoform of Embp is overexpressed even in TSB, while mutant M135 is an isogenic mutant of 1585 v in which expression of Embp is interrupted by insertion of transposon Tn917.

Staphylococcus epidermidis (S. epidermidis) 1585 is a specific strain of S. epidermidis that is classified as a wild-type strain. Wild-type in bacterial terminology refers to the strain of an organism that is found in nature, as opposed to those that have been modified or mutated in a laboratory setting. Here are some key points about the 1585 wild-type strain of S. epidermidis:

No Embp Production in TSB: One notable characteristic of the S. epidermidis 1585 strain is that it does not produce Embp (extracellular matrix binding protein) when grown in TSB (Tryptic Soy Broth). Embp is a protein that plays a crucial role in the biofilm formation and adherence of bacteria to surfaces. The absence of Embp production in this strain could impact its ability to form biofilms, a common virulence factor in Staphylococcus infections.
Biofilm Formation: S. epidermidis is known for its ability to form biofilms, especially on medical devices, leading to infections that are difficult to treat. The fact that the 1585 strain doesn't produce Embp in TSB suggests it may have a reduced capacity for biofilm formation under these conditions, which could be significant in understanding and managing such infections.
Research and Clinical Implications: Studying wild-type strains like S. epidermidis 1585 is important for understanding the natural behavior and characteristics of the species. Since this strain behaves differently from other strains in terms of Embp production and possibly biofilm formation, it can provide insights into the mechanisms and genetic factors that control these processes. This knowledge is valuable for developing strategies to prevent and treat infections, especially in hospital and healthcare settings where S. epidermidis infections are common.
Genetic Studies: The 1585 strain can also serve as a baseline or control in genetic studies. By comparing the genome and behavior of 1585 with other strains of S. epidermidis, researchers can identify genetic variations and mutations that may be responsible for different phenotypes, such as increased virulence or antibiotic resistance.

Model Organism for Understanding Staphylococcal Behavior: As a wild-type strain, 1585 offers a model for studying the natural state of S. epidermidis. This is crucial for understanding the fundamental biology of the bacterium, which can help in the development of treatments and interventions against infections caused by more virulent or drug-resistant strains. In summary, the S. epidermidis

1585 wild-type strain is significant in microbiological research due to its natural characteristics, particularly its behavior in biofilm formation and Embp production. Understanding these aspects can contribute to better insights into the pathogenicity and treatment of Staphylococcus infections, particularly in clinical settings where these bacteria are a common source of nosocomial infections.
