COMER-like elements have been identified in one of the two major hospital adapted drug resistant ST2 lineages and showed high stability. ACME showed high variation even between isolates of the same ACME type and ST. Comparative analysis identified a cluster of ACME-positive isolates with most of them belonging to ST48. Analysis showed the presence of SCC mec in the majority of isolates. A core-genome phylogenetic tree and genome based MLST typing showed that more than half of the isolates belong to the clinically predominant sequence type2 (ST2) and these isolates have been found to split into two lineages within the phylogenetic tree. epidermidis clinical isolates, collected between 20 in a Scottish hospital, were sequenced. We aimed in this study to evaluate the presence and diversity of ACME and COMER-like elements in our S. epidermidis or any other staphylococcal species. Several studies found that ACME is more prevalent, and exhibits greater diversity, in Staphylococcus epidermidis while COMER has not been identified in S. These two mobile elements are associated with resistance to copper, which has been related to host fitness and survival within macrophages. The epidemiological success of methicillin-resistant Staphylococcus aureus USA300 has been associated with the presence of two mobile elements, the arginine catabolic mobile element (ACME) and the copper and mercury resistance (COMER) element. 3Department of Tropical Disease Biology, Liverpool School of Tropical Medicine, Liverpool, United Kingdom.2School of Medicine, Medical Sciences and Nutrition, University of Aberdeen, Aberdeen, United Kingdom.1Department of Genetics and Genome Biology, University of Leicester, Leicester, United Kingdom.Morrissey 1, Karolin Hijazi 2 and Marco R.

The tools described on this page are provided using Search and sequence analysis tools services from EMBL-EBI in 2022 The EBI has a new phylogeny-aware multiple sequence alignment program which makes use of evolutionary information to help place insertions and deletions.

Transform a Sequence Similarity Search result into a Multiple Sequence Alignment or reformat a Multiple Sequence Alignment using the MView program.Ĭonsistency-based MSA tool that attempts to mitigate the pitfalls of progressive alignment methods. Suitable for medium-large alignments.Īccurate MSA tool, especially good with proteins. MSA tool that uses Fast Fourier Transforms. Very fast MSA tool that concentrates on local regions. Suitable for medium-large alignments.ĮMBOSS Cons creates a consensus sequence from a protein or nucleotide multiple alignment. New MSA tool that uses seeded guide trees and HMM profile-profile techniques to generate alignments. From the output, homology can be inferred and the evolutionary relationships between the sequences studied.īy contrast, Pairwise Sequence Alignment tools are used to identify regions of similarity that may indicate functional, structural and/or evolutionary relationships between two biological sequences. Multiple Sequence Alignment (MSA) is generally the alignment of three or more biological sequences (protein or nucleic acid) of similar length.
