RESUMO
Listeriosis is a food borne illness of significant public health concern, caused by consumption of food contaminated by gram negative bacilli, Listeria monocytogenes. Clinical listeriosis is relatively rare and it has varying spectrum of presentation, ranging from severe sepsis in immune-compromised individuals, febrile gastroenteritis and meningo-encephalitis in infants and adults. This disease is under reported in developing nations due to the lack of awareness and inadequate laboratory facilities to promptly isolate and identify the organism. We report a case of sporadic food-borne listeriosis, in an otherwise healthy individual presenting with meningo-encephalitis. Prompt identification and appropriate antibiotic therapy led to a favorable outcome.
