Annals of the New York Academy of Sciences, EarlyView. Staphylococcus aureus is a pathobiont capable of colonizing and infecting most tissues within the human body, resulting in a multitude of different clinical outcomes. Adhesion of S. aureus to the host is crucial for both host colonization and the establishment of infections. Underlying the pathogen's success is a complex and diverse arsenal of adhesins.

In this review, we explore the plasmidome of A. salmonicida. Knowledge has accumulated about this diverse plasmidome, which can be separated into three categories (R‐plasmids, virulence plasmids, and cryptic plasmids). The advance of DNA sequencing technology has played an important role in the elucidation of complete sequences, giving greater clarity to study the roles and importance of plasmids in A. salmonicida.

Achalasia is a primary motility disorder of the esophagus, and while there are several treatment options, there is no consensus regarding them. When therapeutic intervention for achalasia fails, a careful evaluation of the cause of the persistent or recurrent symptoms using upper endoscopy, esophageal manometry, and contrast radiologic studies is required to understand the cause of therapy failure and guide plans for subsequent treatment.

Our review provides a comprehensive treatise on the progress in understanding teixobactin chemistry, structure−activity relationships, and mechanisms of antibacterial activity. Teixobactin represents an exciting starting point for the development of new antibiotics that can be used to combat multidrug‐resistant bacterial (“superbug”) infections.

Whole‐genome sequence analysis was performed on a multidrug‐resistant Providencia rettgeri PR002 clinical strain isolated from the urine of a hospitalized patient in Pretoria, South Africa, in 2013.

We performed a literature search for English research papers, published between 2013 and 2018, reporting on plasmid‐mediated carbapenem resistance. A rise in both carbapenemase types and associated plasmid replicon groups was seen, with China, Canada, and the United States recording a higher increase than other countries.
