N.86 – LEGIONELLA PNEUMOPHILA QUANTIFICATION IN BIOAEROSOL

The disease Legionnaires’ disease was first recognised as a result of an outbreak of acute pneumonia that occurredat the Convention of the American Legion in Philadelphia USA in 1976. The route of infection has been recognised as the inhalation of small aerosol containing bacteria of the Legionella sp into the lungs of the host animal. […]

N.82 – Sampling viable organisms by microbial active air samplers

Importance of the impaction on agar surface. Effect of jet velocity, nozzle size, nozzle distance from the agar surface, quality of medium, volume of medium inside the culture, expiration date of the plate, moisture content and sterility of the medium, temperature should be considered to obtain the optimization of these variables. These facts are determinative […]

Sequential sampling with TRIO.BAS DUO and TRIO in Clean Room, Isolators, RABS With TRIO.BAS DUO microbial air sampler (with 2 separated aspirating chambers) and TRIO.BAS TRIO microbial air sampler (with 3 separated aspirating chambers) it is possible to monitor two or three different environments or spots of the same environment, simultaneously. Sequential sampling in Clean […]

N.74 – Routine monitoring of air quality required in areas used for compounding sterile preparations

Introduction On January 1, 2004 Chapter <797>, of the United States Pharmacopeia/National Formulary (USP27/NF22) entitled “Pharmaceutical Compounding Sterile Preparations”, became effective. USP Chapter <797> details the procedures and requirements for compounding sterile preparations and sets standards that are applicable to all practice settings in which sterile preparations are compounded. Since USP Chapter <797> is considered […]
