| Abstract |
A 62-years-old man with hypopharyngeal cancer was admitted due to dysphagia. After 33 days in the hospital, the patient developed a temperature of 39.0°C and gram-negative bacilli were isolated from two sets of blood cultures. The isolated bacillus formed yellow pigmented colonies and was identified as Pseudomonas psychrotolerans using 16S rRNA analysis. No apparent source of bacteremia was identified after a careful review. The patient was initially treated with piperacillin/tazobactam but was switched to ciprofloxacin and clindamycin. The fever resolved within one day, and no relapse was observed after three months. P. psychrotolerans was first reported in 2004. There were only two reports on this bacterium, and both of them were not human cases. Therefore to the best of our knowledge, this is the first report on P. psychrotolerans bacteremia in humans. |
