RESUMO

Objective To study expiration time and the origin of bacteria for the sterile packages of strategic reserve between inland region and littoral under natural environment.Methods We prepared operation dressing package,apparatus package as well as dressing and apparatus mixed package with double- cotton and to be deposited in storage boxes of combat readiness warehouse under natural environment after pulsing vacuum steam sterilization.Three packages of every kind were put in a storage boxes and samples were taken from the packages and underwent bacterial culture at different time-points.Meanwhile,the bacteria strains in combat readiness warehouse' air and in the storage boxes were cultured and performed with homology analysis.Results Expiration time of sterile packages of strategic reserve was 40d in inland region whereas 24d in littoral.The major bacteria were G+ bacilli and G+ staphylococus in sterile packages of strategic reserve,combat readiness warehouse' air and storage boxes in two regions.In inland region,the 16~23SrRNA ITS sequences of bacteria strains in sterile packages shared about 97%~100% homology with which between the air bacteria strains in combat readiness warehouse and the storage boxes whereas it was about 98%~99% homology in littoral.Conclusions The storage environment is the most influential factor on expiration time of sterile packages of strategic reserve.The bacteria in sterile packages of strategic reserve came from the air of combat readiness warehouse.To ensure the expiration time of sterile package of strategic reserve,corresponding management methods are important guarantee which can provide new methods about management on strategic reserve.
