Keywords: Streptococcus pneumoniae pneumonia checks
Peripheral blood white blood cell count and neutrophil significantly increased up to (15 to 40) × 109 / L, and even up to (50 to 70) × 109 / L, a left shift can be seen mainly in neutrophils toxic particles. But there are a few children with leukopenia, indicating serious condition
Pathogens checks done airway secretions blood the pleural effusions culture may be Streptococcus pneumoniae. Direct sputum smear staining Gram-positive diplococci arranged in pairs with diagnostic significance and growth of Streptococcus pneumoniae sputum and blood cultures to confirm the diagnosis, but positive rate is not high.
Serological check Streptococcus pneumoniae pneumonia in children from 10% to 30% presence of bacteremia but due to the early application of antibiotics, the domestic blood culture positive rate is very low. Most of the etiological diagnosis of pneumococcal pneumonia by serological methods such as the determination of in serum urine or saliva of Streptococcus pneumoniae antigen but also the authors believe that this method can not distinguish between the infection and colonization of Streptococcus pneumoniae has recently been reported by measuring serum pneumolysin (Pneumolysin) antibodies, or containing to diagnose circulating immune complexes for the capsular polysaccharide-specific capsular polysaccharide of Streptococcus pneumoniae species-specific complexes, the protein antigen pneumolysin antibody, but still inadequate sensitivity in infants
Can be collected blood and urine samples using methods such as CIE, LA detection of Streptococcus pneumoniae capsular antigen used the radioimmunotherapy germicidal the force test EIJSA method determination of Streptococcus pneumoniae antibody as an aid to diagnosis. C-reactive protein is often positive.
4. Addition, urinalysis visible trace protein, most children with nasopharyngeal secretions cultured Streptococcus pneumoniae.
