ROJAS-JAIMES, Jesús; DIAZ-TELLO, Alberto  and  KERRIGAN, Meredith. In Vitro growth and unusual Campylobacter morphology isolated from a patient with bacteremia. CES Med. [online]. 2019, vol.33, n.2, pp.144-150. ISSN 0120-8705.  https://doi.org/10.21615/cesmedicina.33.2.8.

Campylobacter sp. It is a bacterium that adapts to different conditions and allows a change in its form and metabolic requirements, making microbiological diagnosis difficult in such conditions. We present the case of a 65-year-old cancer patient with bacteremia caused by Campylobacter sp. The culture of classical microbiology was developed in microaerophilic at 42 o C, aerobic culture on blood agar at 37 o C and aerobic blood culture at 37 o C. In addition, the polymerase chain reaction was performed to identify the agent. The bacteria grew in all media showing its thermotolerance and tolerance to different concentrations of oxygen, in addition to presenting a spiral shape in the aerobic blood culture. Finally, we emphasize the physiological flexibility of the bacterium to adapt to different conditions and the importance of the molecular test to identify the agent especially in aerobic growth in spiral form, which could be confused with other spirochetes that cause febrile episodes.

Keywords : Campylobacter sp.; Bacteremia; Spiral bacterium; Febrile.
