ABSTRACT

Streptococcus agalactiae is a gram positive cocci that can be grouped in pairs or short chains; it is a facultative anaerobe, causative of beta hemolysis, and is usually associated with pathologies in the newborn, such as sepsis (early or late) in up to 90%, pneumonia (40%) and meningitis (30%). Serotype III causes more than two thirds of the cases of neonatal disease; 15% of the isolates of this serotype in Mexico are related to high virulence strains. The rate of genital colonization in Latin America varies from two to 20.4%; in Mexico the isolation of serotype III occurs in 32.9%, with incidence of serious neonatal infection from 0.3% to 1%. We report the case of a 26-day-old newborn, who began her illness with nonspecific symptomatology and within a few hours developed a febrile syndrome with septic shock, cardiomyopathy and death a few hours after the onset of symptoms. Risk factors, preventive measures described by consensus, clinical evolution of the condition and clinical manifestations derived from its pathophysiology are analyzed.
