title: Sensitization to grass, ragweed, mugwort pollen allergens in Japanese monkeys (Macaca fuscata): preliminary report.
abstract: BACKGROUND
  The natural occurrence of Japanese cedar (CJ, Cryptomeria japonica) pollinosis has been reported in Japanese monkeys (Macaca fuscata). Furthermore, most of these monkeys with CJ pollinosis have immunoglobulin (Ig) E sensitization to Japanese cypress (Chamaecyparis obtusa) pollen. However, specific IgE to other pollens has not yet been reported.
  
  
  OBJECTIVE
  The present study was designed to investigate IgE sensitization of Japanese monkeys to grass, ragweed, and mugwort pollen.
  
  
  METHODS
  Serum samples from 47 monkeys as a general population in one troop were collected at random. We measured specific IgE to grass, ragweed and mugwort pollen. Next, 10 monkeys with CJ pollinosis from the same troop were also examined for their IgE sensitization to grass, ragweed, and mugwort pollen.
  
  
  RESULTS
  Of 47 monkeys, 13 (28%) had specific IgE to CJ pollen, 15 (32%) to grass pollen, five (11%) to ragweed pollen, and three (6%) to mugwort pollen. Furthermore, CJ pollinosis monkeys seemed to be sensitized to these pollen allergens with higher frequency; of 10 monkeys, 10 (100%) had specific IgE to CJ pollen, six (60%) to grass pollen, four (40%) to ragweed pollen, and two (20%) to mugwort pollen.
  
  
  CONCLUSIONS
  Japanese monkeys had specific IgE to grass, ragweed, and mugwort pollen in addition to CJ pollen.
