[Study on bacteremia due to community-acquired infection in infants and children without underlying diseases]

Between July 1988 and June 1998, 22 pediatric patients without underlying diseases were diagnosed as bacteremia caused by community-acquired infection in Asahikawa Kosei Hospital. The age range of the patients was from 7 days to 4 years. Their diseases were meningitis in 6, urinary tract infection in 6, respiratory tract infection in 4, skin infection in 2, and unknown origin in 4. The causative organisms were Escherichia coli in 7, Haemophilus influenzae in 4, Streptococcus pneumoniae in 4, Staphylococcus aureus in 2, Streptococcus pyogenes in 1, Streptococcus agalactiae in 1, Listeria monocytogenes in 1, Moraxella catarrhalis in 1, and Rahnella aquatilis in 1. Though 21 patients recovered with antimicrobial treatment, only one patient with H. influenzae meningitis had lateral deafness and paresis in the lower limbs as sequelae.
