RESUMO
Purpose: Flavobacterium lindanitolerans is an environmental Gram-negative, non-spore-forming rod which is usually not considered to be a human pathogen. Isolation from human clinical samples has been described only once. We report the first case of meningoencephalitis and bacteraemia with Flavobacterium lindanitolerans. Case description: A 76-year-old female presented with fever, headache, alteration of mental status, marked meningism and dysarthria. A lumbar puncture demonstrated cerebrospinal fluid findings consistent with bacterial meningitis, and a broad-spectrum antibiotic therapy was initiated. Blood and cerebrospinal fluid cultures revealed a growth of Flavobacterium lindanitolerans. Based on antimicrobial susceptibilities testing, antibiotic treatment was changed to levofloxacin, resulting in a remission of the clinical symptoms after 21 days of treatment. Conclusion: Flavobacterium species are extremely rare human pathogens. However, some of them have been reported to cause opportunistic infections. We describe the first case of meningoencephalitis and bacteraemia caused by Flavobacterium lindanitolerans which was effectively treated with levofloxacin for 21 days. LEARNING POINTS: This is the first case of a meningoencephalitis and bacteraemia with Flavobacterium lindanitolerans.Levofloxacin can be given for 21 days as a treatment of F. lindanitolerans.
