121 - Evaluation of Microbial Contamination in Hospital, Clinic, Health Care Premises, etc

The Guide lines for the evaluation of the microbial environmental contamination in the operating rooms of hospital, clinic and health care premises are repported in the document of World Health Organisation (WHO), National Health Service (NHS).

120 - Correrct use of reference graphic in trends for Microbiological Environmental Data (MED)

The microbiological environmental monitoring data is part of a continuum. Periodic analyses of environmental data should be formally prepared, reviewed by microbiological QA and presented for informational purposers by the production and general personnel responsible for speci c areas, operations and products.

119 - Expulsion of Droplets during a Sneeze

During a sneeze, millions of tiny droplets of water and mucus are expelled at about 200 miles per hour (100 metres per second). The droplets initially are about 10-100 micrometers in diameter, but they dry rapidly to droplet nuclei of 1-4 micrometres, containing virus particles or bacteria. This is a major means of transmission of several diseases of humans, shown in the table.

118 - TRIO.BAS Aspiration Cycle “Multimode”

The microbial air sampling can be programmed by sub-samples to obtain results during longer time. All TRIO.BAS air samplers can be programmed for “Delay time”, “Interval time”, “Sampling time”- It is therefore possible to obtain sequential sampling spaced out by several standby times: -Delay time from 1 to 120 minutes. -Sampling intervals up to 100. -Sampling time up to 60 minutes. These performances are very useful for sampling “AT REST” and “IN OPERATION”.

117 - Airborne Bacteria, Viruses and Spores in poultry premises by High Efficiency Electrostatic Bacterial Air Sampler

It is well known that anytime there are birds infected with pathogenic organisms in a poultry area, these microorganisms are shed in some way and most of them can be recovered from room surfaces or from the air. A high ef ciency, portable electrostatic bacterial air sampler (EBAS) was designed for recovering low levels of bioaerosols in poultry spaces.

115 - Protocol of Dressing in Cleanroom

The correct dressing of operators in controlled contamination environment is a key point to guarantee the lowering of the particle and microbial count to requested values. This aim is achieved by adopting a well-de ned procedure. One example is suggested by Philip Austin, resumed in the publication “Modular Cleanroom "Terra Universal Vol. 10. N. 3. It illustrates proper donning step-by-step itinerary.

114 - The Gamma Irradiation

Gamma rays are a form of electromagnetic radiation-like x-rays, but with higher energy. The primary industrial sources of gamma rays are radionuclide elements such as Cobalt 60, which emit gamma rays during radioactive decay. Gamma rays pass readily through plastics and kill bacteria by breaking the covalent bonds of bacterial DNA. They are measured in units called kiloGrays (kGy). Gamma irradiation provides a number of bene ts in cost and sterility assurance. It can be applied under safe, wellde ned, and controlled operating parameters, and is not a heat- or moisturegenerating process. Consequently, there is no heat stress and condensate drainage or outgassing is not required. Most importantly, there is no residual radioactivity after irradiation.

Cleanroom environments are not sterile as long as people populate them. The only viable approach is to have people gowned properly and strictly adhere to good aseptic practices and techniques.

112 - Use of “Daily Shift” Sterile Aspirating Head for TRIO.BAS Air Samplers in Cleanroom

The “Daily Shift” head sterile aspirating head avoids the sterilization of the stainless steel head of the air sampler. It saves time and it certi es the sterilization with an of cial document. This document is requested by the regulatory authorities. The double irradiated sterile packaging allows you to have always available aspirating head ready for use. A single head is used during a complete daily working cycle in clean room. The transparency of “Daily Shift” head is useful to verify that th culture plate is inserted into che aspirating chamber. The plastic of the “Daily Shift” is reciclable.

111 - Applied microbiology in Cleanroom

Air samples are quantitatively accurate. Microbiology is an exact science. Contamination detect by an active air samplers means that the product made at the same time is contaminated. Air sampling devices are generally equal in their ability to detect contamination. Statistic + sampling plan analysis are suf cient to enable the manager to create a formula for determining “accept/reject” of a product lot. Microbes will survive forever in a cleanroom unless killed by a disinfectant.
