()is a species of nontuberculous mycobacteria that is a rare cause of disease in humans and is usually associated with aquatic exposures. Symptoms manifest, on average, three weeks after exposure, although cases with longer incubation periods have been reported in the literature. Herein, we describe an unusual case presentation of an  infection in the left upper extremity of a heart transplant recipient.

Bacterial cell walls contain peptidoglycan (PG), a scaffold that provides proper rigidity to resist lysis from internal osmotic pressure and a barrier to protect cells against external stressors. It consists of repeating sugar units with a linkage to a stem peptide that becomes cross-linked by cell wall transpeptidases (TP). While synthetic PG fragments containing l-lysine in the third position on the stem peptide are easier to access, those with -diaminopimelic acid (-DAP) pose a severe synthetic challenge.

Addressing the growing problem of antibiotic resistance requires the development of new drugs with novel antibacterial targets. FtsZ has been identified as an appealing new target for antibacterial agents. Here, we describe the structure-guided design of a new fluorescent probe (BOFP) in which a BODIPY fluorophore has been conjugated to an oxazole-benzamide FtsZ inhibitor.

Article Synopsis
  • Peptidoglycan (PG) is a crucial component of bacterial cell walls, providing strength and structure, but its remodeling processes and the effects of these changes on bacterial biology are not well understood.
  • Recent advancements have allowed the development of new probes that specifically target L,D-transpeptidases (Ldts), enzymes that play a key role in PG cross-linking, which is important for maintaining cell wall integrity and influencing antibiotic efficacy.
  • This research demonstrates that small modifications to PG can influence Ldt activity and cross-linking, paving the way for a better understanding of how various cross-linking processes work together to shape PG structure and function.

Background: The occurrence of perioperative seizures in patients with a preexisting seizure disorder is unclear. There are several factors unique to the perioperative period that may increase a patient's risk of perioperative seizures, including medications administered, timing of medication administration, missed doses of antiepileptic medications, and sleep deprivation. We designed this retrospective chart review to evaluate the frequency of perioperative seizures in patients with a preexisting seizure disorder.
