Streptococcus equi subspecies zooepidemicus Meningitis, Septicemia, and Brain Infarcts in a Costa Rican Infant.

, an equine commensal bacterium, is a rare etiology of septicemia and meningoencephalitis in humans and is extremely infrequent in children. Scarce literature has been published about its clinical presentation, treatment and outcomes in infants. Here, we describe a case of septicemia and meningoencephalitis in a five-month-old Costa Rican infant that was confirmed by peripheral blood and cerebrospinal fluid (CSF) cultures in a regional hospital of the Pacific coast of Costa Rica who developed multiple ischemic cerebral infarcts secondary to infectious vasculitis, a subdural empyema and serious neurological sequelae.

Culture-Proven Disseminated and Meningeal Histoplasmosis Presenting as Septic Shock and Autoimmune Hemolytic Anemia in an Infant.

Disseminated histoplasmosis is the most common clinical presentation of histoplasmosis in human immunodeficiency virus (HIV) negative infants from Costa Rica and Latin America. Initial presentation as septic shock and autoimmune hemolytic anemia is uncommon. Even more, detection of by culture in peripheral blood and cerebrospinal fluid (CSF) is extremely rare.
