Abstract
Sir—Although Leclercia adecarboxylata was initially described in 1962 [1], reports of clinically significant infections involving this motile, gram-negative bacillus are uncommon. In the world's literature, 8 cases have been reported in which L. adecarboxylata was isolated from infected patients [2, 3]. In 4 of these cases, L. adecarboxylata was isolated from the blood of patients with an underlying medical condition (2 patients with hepatic cirrhosis, 1 child who was receiving long-term total parenteral nutrition, and 1 adult with neutropenia who had received a bone marrow transplant). In the other 4 cases, L. adecarboxylata was isolated from patients with mixed microbial infection (from lower extremity wound infections in 3 patients and from the sputum of 1 patient with adult Still's disease and pneumonia), which raises questions regarding the organism's role in these infections. We write to report another case involving an infant with acute lymphoblastic leukemia (ALL).
