When good bacteria behave badly: a case report of sepsis in an immunocompetant adult.

Reports of unusual microorganisms causing human infections are on the rise due to transitions in epidemiological trends. Commensal/normal flora which are otherwise termed as 'good bacteria' are now causing infections in different group of patients, mostly immunocompromised individuals. Various host and environmental factors play a pivotal role in microbial transmigration from their normal habitat into the blood and other body sites. We report one such 'good bacterium' associated with sepsis in a patient who was given the same bacterium in the form of probiotics.
