RESUMO
The aim of this prospective study in Morocco was to investigate the causes of invasive bacterial diseases in children in order to inform antibiotic therapy and vaccine choices. Of 238 children aged </= 5 years admitted to the Children's Hospital of Casablanca for invasive diseases over a 12-month period, 185 were diagnosed with bacterial infection: 76 had chest-X-ray-confirmed pneumonia, 59 had meningitis and 50 had sepsis. Streptococcus pneumonia was the most common pathogen identified [n= 24], followed by Neisseria meningitides [n= 18, all group B] and Haemophilus influenza [n= 11]. The rate of penicillin non-susceptibility was 62.5% among Str. pneumoniae isolates and 11.1% among N. meningitidisand all isolates were ceftriaxone-susceptible. Of the 11 H. influenzae isolates, only 1 produced a beta-lactamase. The 5 predominant Str. pneumoniaeserotypes were 19F, 14, 23F, 6B and 19A and the theoretical coverage of the 7, 10 and 13-valent pneumococcal conjugate vaccines was 60%, 78% and 91% respectively

Susceptibility of 88 clinical Streptococcus pneumoniae isolates, 116 Haemophilus influenzae isolates and 80 Moraxella catarrhalis isolates to 6 fluoroquinolones--ciprofloxacin, ofloxacin, levofloxacin, trovafloxacin, grepafloxacin and gemifloxacin--were determined. Isolates were from patients with invasive disease at 4 hospitals in Saudi Arabia between 1996 and 1998. S. pneumoniae isolates were fully susceptible to trovafloxacin, grepafloxacin and gemifloxacin; susceptibility to ofloxacin and levofloxacin was 97.7% and 98.9% respectively. H. influenzae isolates were susceptible to all agents, except for trovafloxacin [99.1%]. M. catarrhalis strains were fully sensitive to all agents except ofloxacin [97.5%]. No isolates were resistant to gemifloxacin or grepafloxacin

Vaccines produced in accordance with WHO formulas, differ in concentration from those used in United States according to FDA formulas. We aimed to compare the immunogenicity of both formulas. Infants who were 6 weeks old were randomly put into 3 groups to receive 3 doses of vaccines at 6 weeks, 3 months and 5 months of age. The vaccines consisted of Haemophilus influenzae type b vaccine, diphtheria-tetanus-pertussis and oral polio vaccine. Antibody levels for polyribosylribitol phosphate [PRP], tetanus, diphtheria and poliovirus were measured 1 month after the third dose of vaccines. Although diphtheria and tetanus antigens in the FDA formula are half the concentration of the WHO formula, anti-tetanus and anti-diphtheria antibodies were significantly higher. No difference was found between groups regarding oral poliovirus vaccine
