[Neonatal streptococcus group B infection in Yaoundé (Cameroon). Epidemiologic and clinical aspects]. / Infection néonatale à streptocoque du groupe B à Yaoundé (Cameroun). Aspects épidémiologiques et cliniques.

This study was designed to investigate epidemiologic and clinical features of neonatal group B streptococcal infections. Sixty cases seen over a 60-month period were reviewed. Incidence was 0.8% of admissions. Most affected infants were from low-income families (86.7% of mothers were unemployed and 73.5% of homes were without running water). Neonatal infection was delayed in most instances (76.67%). Fetid vaginal discharge (60%) and premature rupture of the membranes (35%) were the main findings upon history taking. Abnormal body temperature regulation (76.7%) was the most prominent clinical manifestation. Respiratory distress developed in 25% of patients. Meningeal involvement occurred in 73.3% of patients. Serotype B III was recovered in 31 of the 34 cases (91%) in which serotype was determined. Mortality rate was 21.7% and permanent sequelae occurred in 8.3% of patients.

[Neonatal septicemia and meningitis caused by gram-negative bacilli in Yaondé: clinical, bacteriological and prognostic aspects]. / Les septicémies et méningites néonatales a bacilles gram négatifs a Yaoundé: aspects cliniques, bactériologiques et pronostiques.

Based on 139 cases collected in 36 months, the authors show that neonatal sepsis and meningitis with Gram negative bacilli represent 62.33% of confirmed neonatal sepsis (223 cases out of 6,784 neonatal hospitalisations). 53.96% of cases are manifest within the first 72 hours of life. 35.25% of these infants are preemies. The principal predisposing factors are: foul-smelling leukorrhea (45.23%), prolonged rupture of membranes (26.62%) and notion of resuscitation (36.69%). The most important clinical signs are: thermal dysregulation (47.48%), tonus disturbances (35.97%) and respiratory distress (25.90%). Sepsis make up 85.61% of cases; the principal germs isolated being: Acinetobacter (21.58%), Pseudomonas (15.83%), Escherichia coli (14.39%), Enterobacter (12.95%), Klebsiella (11.51%).
