“…Nocardia species are involved in human infection more often than are Rhodococcus species, but infrequent infections with Rhodococcus species have been reported in immunocompromised hosts (13,17). Actinomycete infections often are clinically indistinguishable from other infections of bacterial origin.…”

High-performance liquid chromatography analysis of mycolic acids as an aid in laboratory identification of Rhodococcus and Nocardia species

High-performance liquid chromatography analysis of the p-bromophenacyl esters of mycolic acids from whole organisms gave chromatographic patterns that were useful in differentiation of Rhodococcus and Nocardia species. Rhodococcus equi, R. erythropolis, and R. rhodochrous contained more-polar mycolic acids and were easily separated from the less-polar mycolic acid-containing species of R. sputi, R. bronchialis, R. corallinus, R. rubropertinctus, and R. terrae. The less-polar mycolic acid-containing Rhodococcus species showed chromatographic patterns that partially overlapped (in elution times) the patterns of Nocardia asteroids, N. otitidiscaviarum, and N. brasiliensis, but the larger number of peaks in the last species made separation between the genera possible. Distinct chromatographic patterns were found for most species, except for R. equi strains that showed two different patterns. Strains of R. rubropertinctus and R. terrae appeared identical. N. asteroides and N. otitidiscaviarum showed similar mycolic acid patterns.

Three hundred expectorated sputa from patients suffering from chest disorders were examined microscopically and cultured on various media. Among other micro-organisms isolated there were four strains of Rhodococcus aurantiacus (Gordona aurantiaca), one each of Rh. erythropolis, Rh. pellegrino, Rh. rubropertinctus and Rh. rhodnii. Suspensions in 5% hog gastric mucin were virulent for immuno-suppressed white mice and the pathology of their lungs was compatible with those produced in experimental nocardial and rhodococcus infections. The in-vitro antibiogram was similar to that of Nocardia asteroides. Two of the patients from whom Rh. aurantiacus and Rh. pellegrino were isolated responded bacteriologically and clinically to treatment with co-trimoxazole. The frequency with which these rhodococci were isolated and the clinical conditions of the patients strongly indicated a pathogenic role for some Rhodococcus species. It is suggested that rhodococci should be sought in chronic pulmonary infections, particularly in those who are immuno-compromised or debilitated, and their aetiologic role determined.
