Abstract
A 36-year-old female was admitted to hospital for debridement of chronically inflamed tendon sheaths and adjacent tissues near the left ankle. Despite antibiotic therapy and initial surgical interventions, the inflammation had progressed slowly over 16 months. Histopathological examination of excised tissues in September 1973 revealed a chronic granulomatous inflammation of tendon sheaths and muscle. Many branched hyphal segments, intercalary swollen cells, and a few conidia-like bodies were seen in sections, and also in KOH- and PAS-stained slides prepared from homogenized tissues. Culture of homogenized tissues yielded pure colonies ofScopulariopsis brevicaulis.Sensitivity tests were initially begun with amphotericin B, potassium iodide, and potassium tartrate (0·05-15 μg/ml of the phytone-yeast extract agar), and no inhibitory effect was observed. Subsequently, amphotericin B, antimony, 5-fluorocytosine (5-FC), griseofulvin, hamycin, and mycostatin were tested (25-300 μg/ml of the phytone-yeast extract agar). Of these chemicals, griseofulvin and hamycin proved to be most effective. Antimony and 5-FC were ineffective, and mycostatin produced a negligible effect on growth. The four strains ofLysobacter antibioticus,the producer of myxin antibiotic, strongly inhibited the growth of the fungus.
