Neonatal citrobacter sepsis: clinical and epidemiological aspects.

Fourteen neonates were diagnosed to have Citrobacter sepsis during 1986-89, representing 4.6% of all cases with bacteriologically proven sepsis. Most of these infants were low birth weight (mean 2046 gm, +/- 750) and preterm (mean 34.8 weeks, +/- 3.8). Mean age at onset of sepsis was five days. In 10 cases the hematological profile was suggestive of sepsis. Infants had clinical evidence of multisystem infection; 2 with septic arthritis and 3 meningitis. The case fatality rate was 61%. Resistance to antibiotics was frequent. Citrobacter species were also cultured from other sites: umbilical stumps, eye swabs, urine, skin pustules and umbilical catheter tips. The epidemiological features and virulence of this organism call for vigilance and strict control measures.
