4 Cleaning: allows the physical removal of microorganisms allows prevents inactivation of the disinfectant by organic matter complete surface contact during further decontamination procedure Through cleaning of items is a prerequisite before disinfection and sterilization is commenced Disinfection: by heat or chemicals will destroy microorganism but not bacterial spores chemical disinfection does not necessarily kill all microorganisms present but reduces them to a level not harmful to health Antiseptics: the agents must have effective antimicrobial activity must not be toxic to living tissues chemicals used to kill microorganisms on skin or living tissue Sterilization: a process which achieves the complete destruction or removal of all microorganisms, including bacterial spores

6 Level of disinfection Spores TB Vegetative bacteria Fungi Nonlipid & small viruses Lipid & mediumsize viruses Cold chemical sterilization High + * Inter-mediate - might most most some + Low - - +/- +/- +/- + * high-level disinfectants may not be able to kill large numbers of spores

7 Unlike sterilization, disinfection is not sporicidal. A few disinfectants will kill spores with prolonged exposure times (3 12 hours); these are called chemical sterilants. At similar concentrations but with shorter exposure periods (e.g., 20 minutes for 2% glutaraldehyde), these same disinfectants will kill all microorganisms except large numbers of bacterial spores; they are called high-level disinfectants. Low-level disinfectants can kill most vegetative bacteria, some fungi, and some viruses in a practical period of time (<10 minutes). Intermediate-level disinfectants might be cidal for mycobacteria, vegetative bacteria, most viruses, and most fungi but do not necessarily kill bacterial spores. Germicides differ markedly, primarily in their antimicrobial spectrum and rapidity of action.

9 Class of item Use of item Example Critical Semi-critical Non-critical Enter vascular system or sterile body tissues Comes in contact with intact mucous membranes Touches only intact skin Hypodermic needle, Scalpels and other surgical instruments, Biopsy forceps Vaginal spec., Anaesthetic equipment, flex. Endoscopes Blood pressure cuff, Baby weigh scale, Examining table top Decont. level needed Sterilization High-level disinfection (by heat or chemicals) Intermediatelevel or lowlevel disinfection

12 Biofilms are microbial communities that are tightly attached to surfaces and cannot be easly removed Microbes within them can be resistant to disinfectants by multiple mechanisms, including physical characteristics of older biofilms, genotypic variation of the bacteria, microbial production of neutralizing enzymes, and physiologic gradients within the biofilm (e.g., ph) Bacteria within biofilms are up to 1,000 times more resistant to antimicrobials than are the same bacteria in suspension

13 They are present on numerous medical devices (e.g., contact lenses, pacemakers, hemodialysis systems, urinary catheters, central venous catheters, endoscopes) Enzymes and detergents can degrade biofilms or reduce numbers of viable bacteria within a biofilm.

14 Cleaning and disinfection of the environment Cleaning and disinfection of medical device Disinfection of the skin and mucous membrane

15 The Ideal Disinfectant Broadly active (killing pathogens) Not poisonous (or otherwise harmful) Penetrating (to pathogens) Resistant to inactviation Not damaging to non-livingmaterials Stable Easy to work with Otherwise not unpleasant

16 High Level Hydrogen Peroxide Peracetic acid Glutaraldehyde Formaldehyde Intermediate Level Chlorine Iodine Alcohols Low level Phenolics Quaternary Ammonium Compounds

17 Environmental surfaces

18 Strategies for cleaning and disinfecting surface Potential for direct patient contact Degree and frequency of hand contact Potential contamination of the surface with body substance or environmental sources of microorganism (soil, dust, or water)

19 Justification for Using a Disinfectant Surfaces may contribute to transmission of epidemiologically important microbes (e.g., VRE, MRSA, C. difficile) Needed for surfaces contaminated by blood and OPIM Disinfectants are more effective in reducing microbial load Detergents become contaminated and result in seeding the patients environment with bacteria CDC recommends disinfection of noncritical equipment and surfaces for patients on isolation precautions One product for decontamination of noncritical surfaces (that is, floors and equipment)

20 Pathogens implicated in transmission via contaminated noncritical surfaces Bacteria Acinetobacter, Pseudomonas, Clostridium difficile methicillin-resistant Staphylococcus aureus Vancomycin-resistant Enterococcus spp. Viruses SARS Rotavirus Respiratory syncytial virus (RSV)

34 COMPETITORS INFORMATION COMPARISON TABLE

35 PARTICULES SIZE METHODS LIMITS 15 µ 100µ Pulverization The particles are too heavy. The particles drop too quickly then product does not sufficiently disinfect top surfaces. It has not enough time to threat all surfaces (including those unreachable or hidden). 5 µ 15µ Fogging (Sterinis : 8 to 12µ) An ideal size of the particles. The disinfectant does not accumulate quickly. It has time to reach all surfaces and then to efficiently threat. 1 5µ Nebulization The particles tend to quickly vaporize. Then the disinfectant does not have enough time to threat effectively µ Gas vaporization
