Pseudomonas mesophilica infections in humans

Abstract

Reported here is the case of a patient with metastatic adenocarcinoma of the lung who had bacteremia involving Pseudomonas mesophilica. Of the common laboratory media tested at 35°C, buffered charcoal yeast extract agar and nutrient agar provided the best growth; however, other media suppported growth at lower temperatures. Since blood cultures are routinely subcultured into chocolate agar and then incubated at 35°C, awareness of the characteristics of P. mesophilica and of the isolation techniques as outlined may enhance the recovery of this and related bacterial species.
