The genus Aerococcus spp. comprise microaerophilic, catalase-negative, Gram-positive cocci that show alpha-haemolytic growth on blood agar. They have a tendency to divide on two planes at a 90° angle, and rapid multiplication leads to the formation of Gram-positive cocci in tetrads and irregular clusters. Aerococcus spp. are capable of causing invasive and fatal systemic illnesses, such as endocarditis, bactereamia, arthritis, and meningitis. Due to evolving diagnostic tools, it is now identified as a pathogen in a variety of disorders instead of being considered a contaminant. Most isolates are susceptible to penicillins, but there is increasing resistance to cephalosporins, ciprofloxacin, cotrimoxazole, clindamycin, vancomycin, and tetracycline. Here, authors present a rare case of Aerococcus viridans meningitis in a patient who underwent surgical excision of a left trigeminal Schwannoma, along with the drug susceptibility pattern resistant to most first-line antibiotics used against isolates from Streptococci spp., except doxycycline.
