Thiomarinol and mupirocin are assembled on similar polyketide/fatty acid backbones and exhibit potent antibiotic activity against methicillin-resistant Staphylococcus aureus (MRSA). They both contain a tetrasubstituted tetrahydropyran (THP) ring that is essential for biological activity. Mupirocin is a mixture of pseudomonic acids (PAs). Isolation of the novel compound mupirocin P, which contains a 7-hydroxy-6-keto-substituted THP, from a ΔmupP strain and chemical complementation experiments confirm that the first step in the conversion of PA-B into the major product PA-A is oxidation at the C6 position...

The nucleotide (p)ppGpp is a key regulator of bacterial metabolism, growth, stress tolerance and virulence. During amino acid starvation, the Escherichia coli (p)ppGpp synthetase RelA is activated by deacylated tRNA in the ribosomal A-site. An increase in (p)ppGpp is believed to drive the formation of antibiotic-tolerant persister cells, prompting the development of strategies to inhibit (p)ppGpp synthesis. We show that in a biochemical system from purified E. coli components, the antibiotic thiostrepton efficiently inhibits RelA activation by the A-site tRNA...

International guidelines in peritoneal dialysis (PD) advocate for regular application of topical mupirocin in chronic PD exit-site care. A strong evidence base links this treatment to reduced rates of exit-site infections and peritonitis. However, emerging reports of increasing mupirocin resistance and gram-negative infections are threatening the long-term viability of topical antibiotic ointments as a prophylactic treatment. Medical grade honey has multiple proven antibacterial and wound healing properties...

Linear immunoglobulin A dermatosis of childhood is a rare autoimmune disorder. Its etiology remains unknown, although it has been linked to drugs, infections, immunological diseases and lymphoproliferative processes. We report the case of a 6 year old girl who consulted for perioral bullous lesions without other symptoms. Neither treatment with mupirocin nor methylprednisolone therapy achieved remission of cutaneous lesions. Skin biopsy showed a linear immunoglobulin A dermatosis. It was not possible to start treatment with dapsone because of a partial glucose-6-phosphate dehydrogenase deficiency, so topical treatment was maintained with good evolution of lesions...

Examination of clinical samples indicates bacterial biofilms are present in the majority of chronic wounds, and substantial evidence suggests biofilms contribute significantly to delayed healing. Bacteria in biofilms are highly tolerant of antimicrobials, and little data exist to guide the choice of anti-biofilm wound therapy. Cadexomer iodine (CI) was recently reported to have superior efficacy compared to diverse wound dressings against Pseudomonas aeruginosa biofilms in an ex vivo model. In the current study, the strong performance of CI vs...
