Does a hemocyanin-derived antimicrobial peptide from the penaeid shrimp adopt an alpha-helical structure that specifically permeabilizes fungal membranes?
The massive accumulation of PvHCt at the surface of fungal hyphae and subsequent insertion into the plasma membrane disrupt its integrity as a permeability barrier, leading to disruption of internal homeostasis and fungal death.
Current SCIP guidelines address antibiotic timing but not antibiotic dosage. (The generally accepted recommendation for vancomycin is 15 mg/kg.) Although vancomycin is a narrower-spectrum antibiotic than either cefazolin or clindamycin, our finding of higher SSI rates following prophylaxis with vancomycin only may suggest a failure to use an appropriate dosage rather than an inequality of antibiotic effectiveness.
