Bacteriology:
- between ages six months and two years, hemophilus influenza type B is the main
pathogen in septic arthritis (30-50 %), followed by Staph aureus and strep;
- in infants and children 1 month to 3 years old, the predominant organism causing hematogenous septic arthritis
was historically was haemophilus influenzae, followed by staphylococci and streptococci;
- predominance of H. influenza has significantly declined since a vaccine has been developed;
- in the study by H. Peltola et al. 1998, the incidence of haemophilus influenza septic arhtritis was 0% after
10 years of routine vaccination;
- Reduced incidence of septic arthritis in children by H. influenza type B vaccination.

Major Problems in Infants and Toddlers with Sickle-Cell Disease
Sickle-cell children are very susceptible to infections, usually because their damaged spleens are unable to protect the body from bacteria. The most common organisms causing infection in children with sickle-cell disease are Streptococcus pneumoniae and Haemophilus influenza . Such infections pose a grave threat to infants and very young children with sickle-cell disease. They can progress to fatal pneumonia with devastating speed in infants, and death can occur only a few hours after onset of fever. The risk for pneumococcal meningitis, a dangerous infection of the central nervous system, is 36 times greater than for African-American children and 314 times greater than for white children without sickle cell disease. Before early screening for sickle-cell disease and the use of preventive antibiotics in children, 35% of sickle-cell infants were lost to infections. Fortunately, with screening tests for sickle-cell now required for newborns in most states and with the use of preventive antibiotics in babies who are born with the disease, this terrible mortality rate is dropping significantly. The lung damage caused by sickle cell disease in children can lead to asthma-like bronchial hyperreactivity (an exaggerated response to certain stimuli) in the airways in the lungs.
