| Abstract |
We report a patient suffered from acute pleural effusion and pyothorax, 5 days after surgery of gastroesophageal junction cancer. The patient is a 59-year-old man, who had a sense of postprandial blocking of the chest, in August 2006. He was clinically diagnosed with gastroesophageal junction cancer. On March 12, 2007, his malignant tumors were totally removed by resection of lower esophagus and all stomach after adjuvant chemotherapy. During his recovery, a minor complication of pyothorax occurred on March 15, 2007. The biochemical profile of the isolate produced by a RapID ANA II identification system disclosed Capnocytophaga species. Further identification of the isolate was performed by 16S rRNA gene sequencing. The sequence data obtained were then compared with known 16S rRNA gene sequences in the GenBank database by BLAST search. However, the sequence of the isolate failed to provide an unequivocal identification, as the closest 16S rRNA gene maximum identity was 95.9% (Capnocytophaga ochracea; GenBank accession no. L14635). After several months of the search, repeated the BLAST analysis revealed that the sequence corresponded to the new species Capnocytophaga leadbetteri with 99.4% identity. To our knowledge, this is the first report of an infection in an elderly patient associated with this microorganism. |
