Background: In this case, we report multiple isolations of C. jejuni in a patient with common variable immunodeficiency between 2010 and 2018.
Methods: C. jejuni was investigated in the stool samples of the patient by classical culture method using selective media under microaerophilic atmosphere. Antibiotic susceptibilities of the strains were determined by disk diffusion method.
Results: Eight C. jejuni strains were isolated from the patient. All strains were resistant to ciprofloxacin. An erythromycin susceptible isolate was replaced by a resistant strain within a one- and four-month period. An erythromycin resistant isolate was replaced by a susceptible one within a year. The patient recovered all episodes by intravenous immunoglobulin replacement and antibiotherapy.
Conclusions: Prolonged or recurrent C. jejuni infections should not be overlooked in immunosuppressed patients. The fact that antibiotic susceptibility may change should also be kept in mind.
