The objective of this study was to present a case of ventilator-associated pneumonia (VAP) caused by Chryseobacterium indologenes and to review the literature on this rare pathogen. A 50-year-old female patient hospitalised in the intensive care unit developed VAP. C. indologenes was identified as the sole pathogen in a culture of bronchoalveolar lavage. Targeted treatment, taking into account its natural resistance to many beta-lactam antibiotics, resulted in clinical improvement of the patient. A literature review was conducted on the aetiology and risk factors of VAP, as well as infections caused by C. indologenes, using the PubMed and Google Scholar databases. The analysis indicates that infections caused by C. indologenes are associated with high mortality, particularly among critically ill patients. This case highlights the necessity of considering C. indologenes as a potential pathogen in VAP patients. Early diagnosis and the implementation of targeted antibiotic therapy may improve prognosis.
