Polymicrobial meningitis in a renal transplant recipient – 'cryptococcus neoformans and acinetobacter baumannii coinfection with elizabethkingia meningoseptica superinfection'

Although rare, polymicrobial meningitis has been infrequently reported in renal transplant recipients (RTRs). In this context, we describe a RTR on triple immunosuppression therapy, with stable graft function, who had presented with fever and altered sensorium of 2 days' duration. Evaluation revealed polymicrobial meningitis, which was initially attributed to concurrent infection by Cryptococcus neoformans and Acinetobacter baumannii and was later superinfected with Elizabethkingia meningoseptica. The overall prognosis in polymicrobial meningitis remains dismal, re-emphasizing the importance of early suspicion and prompt microbiological diagnosis for targeted antimicrobial therapy.
