Support for this important work and appropriate time allotted for clinicians to engage in conversations with patients and families must be prioritized in all efforts to redesign primary care.

Infection with a Chlorophyllic Eukaryote after a Traumatic Freshwater Injury t h e e d i t o r : We present two cases of softtissue infection caused by the chlorophyll-con taining alga Desmodesmus arm atus in immuno competent adults. Patient 1, a 24-year-old man who had no underlying medical conditions, sus tained a deep puncture wound to the right foot in a freshwater lake in Texas. Patient 2, a 30-yearold man who also had no clinically significant medical history, received a traumatic freshwater injury while jet-skiing in Missouri; the injury re sulted in open dislocation of the right knee and a coronal unicondylar fracture of the distal right femur. After each patient was admitted to the hospi tal, there was a clinical impression of infection, and tissue specimens obtained intraoperatively (from the tissue of the right foot in Patient 1 and from the adipose tissue of the right knee and the vastus medialis muscle o f the thigh in Patient 2) were sent for microbiologic examination. Gram’s staining revealed polymorphonuclear leukocytes

but no organisms. Routine bacterial and myco bacterial cultures were unremarkable except for a single colony of a coagulase-negative staphylo coccus species isolated on the bacterial culture of the adipose tissue obtained from Patient 2. However, fungal cultures of tissue from the right foot (in Patient 1) and adipose tissue (in Patient 2) grew green colonies consistent with a chloro phyllic organism that was subsequently identi fied as the alga D. armatus. Both patients required surgical debridement, and although they did not receive antifungal therapy, which may be active against some algae,1 both recovered without recurrence of D. armatus infection. Patient 1 had a full recovery without se quelae. However, beginning approximately 1 year after his initial presentation, Patient 2 had recur rent methicillin-susceptible Staphylococcus aureusassociated septic arthritis. The isolates obtained from both patients pro duced green colonies on Sabouraud’s dextrose
