title: [Analysis of bacterial culture and cytology in nasal smear of Japanese ceder pollinosis in pre-season and in season].
abstract: BACKGROUND
  Previously, we reported that nasal symptom appeared in some patients of Japanese cedar pollinosis (JCP) before season. Over than 50% of them had neutrophils (no eosinophil) in their nasal smear (less than 10%; eosinophils), and Staphylococcus aureus or epidermis by culture were detected in more than 90% of them. We thought the attack caused from rhinitis by Staphylococcus.
  
  
  METHODS
  For more details of these bacterium in JCP, we enforced bacterial culture in the nose and cytology in the nasal smear in asymptomatic (PreAs), symptomatic in pre-season (PreSy), and symptomatic in season (InSy) of JCP in 2011.
  
  
  RESULTS
  Positive rates of Staphylococcus aureus were 79%, 75%, 53%, Staphylococcus epidermis; 15%, 10%, 16%, Moraxella catarrhalis; 9%, 25%, 19%, and Streptococcus Pneumonia; 7%, 12%, 16% in PreAs (n=53), PreSy (60), and InSy (70) respectively. Cytology showed that 45% of PreAs (n=53), 65% of PreSy (60) with statistical higher in latter group, and 8% of InSy (72) were only neutrophils in nasal smear. Six% of PreAs, 2% of PreSy, and 51% of InSy were eosinophils. Forty-three% of PreAs with statistical higher than 22% of PreSy and 7% of InSy were nasal cell free.
  
  
  CONCLUSIONS
  These results mean the inflammation by Staphylococcus species or Moraxella catarrhalis might involve symptom appearance in pre-season.
