Is alcohol good for the flu?
Alcohol is effective against influenza virus (252). Ethyl alcohol (70%) is a powerful broad-spectrum germicide and is considered generally superior to isopropyl alcohol. Alcohol is often used to disinfect small surfaces (e.g. rubber stoppers of multiple-dose medication vials, and thermometers) and occasionally external surfaces of equipment (e.g. stethoscopes and ventilators). Since alcohol is flammable, limit its use as a surface disinfectant to small surface-areas and use it in well-ventilated spaces only. Prolonged and repeated use of alcohol as a disinfectant can also cause discoloration, swelling, hardening and cracking of rubber and certain plastics.
Is bleach a disinfectant?
Bleach is a strong and effective disinfectant – its active ingredient sodium hypochlorite is effective in killing bacteria, fungi and viruses, including influenza virus – but it is easily inactivated by organic material. Diluted household bleach disinfects within 10–60 minutes contact time (see Table G.1below for concentrations and contact times), is widely available at a low cost, and is recommended for surface disinfectionin health-care facilities. However, bleach irritates mucous membranes, the skin and the airways; decomposes under heat and light; and reacts easily with other chemicals. Therefore, bleach should be used with caution; ventilation should be adequate and consistent with relevant occupational health and safety guidance. Improper use of bleach, including deviation from recommended dilutions (either stronger or weaker), may reduce its effectiveness for disinfection and can injure health-care workers.
What is the name of the drug that is used to treat infections caused by bacteria?
Antibiotics. The word antibiotic comes from the Greek anti meaning ‘against’ and bios meaning ‘life’ (a bacterium is a life form).’. Antibiotics are also known as antibacterials, and they are drugs used to treat infections caused by bacteria. Bacteria are tiny organisms that can sometimes cause illness to humans and animals.
Which antibiotic is the most effective?
Four types of antibiotics are used to be investigated which is the most effective on a particular bacteria. They are tetracycline, streptomycin, carbenicillin and ampicillin. Whereas two types of bacteria are used which are staphylococcus and Esterichia Coli.

What is the difference between broad spectrum and narrow spectrum antibiotics?
A broad-spectrum antibiotic can be used to treat a wide range of infections. A narrow-spectrum antibiotic is only effective against a few types of bacteria. There are antibiotics that attack aerobic bacteria, while others work against anaerobic bacteria. Aerobic bacteria need oxygen, while anaerobic bacteria don’t.
What is the difference between antibiotics and penicillin?
A bactericidal antibiotic kills the bacteria. Penicillin is a bactericidal. A bactericidal usually either interferes with the formation of the bacterium’s cell wall or its cell contents. A bacteriostatic stops bacteria from multiplying. An antibiotic is given for the treatment of an infection caused by bacteria.
Why do we wash our hands with dettol?
Besides that, we had to wash our hands by using the dettol hand soap before we start and end the experiment. We had to remove all the impurities and bacteria and that was the purpose of washing hand. The problem rose as we did not know whether we had washed our hand to the maximum cleanliness. Consequently, all the apparatus and materials that we used might be affected by our hand. This is done so that there are no infections or contaminations on the agar that might give problems later.
Which antibiotic inhibits the growth of E. coli?
For E.coli, ampicilin showed the greatest inhibition area of bacteria growth with 10.2 cm². Another antibiotic that showed the closest reading is streptomycin. Tetacyclin and carbenicilin showed 5.3 cm² and 4.9 cm² respectively. This result clearly shown that ampicilin is the most effective antibiotic to inhibit the growth of E.coli. Besides that, E.coli is a gram negative bacteria. The cell walls of Gram-negative bacteria have a thinner layer of peptidoglycan with no teichoic acid between the two layers of membranes and then an outer membrane-like layer made up of lipopolisaccharides.
What are the biofilms that protect bacteria from disinfectants?
Biofilms. Microorganisms may be protected from disinfectants by production of thick masses of cells 428 and extracellular materials, or biofilms 429-435. Biofilms are microbial communities that are tightly attached to surfaces and cannot be easly removed.
Why are spores resistant to disinfectants?
For example, spores are resistant to disinfectants because the spore coat and cortex act as a barrier, mycobacteria have a waxy cell wall that prevents disinfectant entry, and gram-negative bacteria possess an outer membrane that acts as a barrier to the uptake of disinfectants 341, 343-345.
What is interference in germicides?
Most commonly, interference occurs by a chemical reaction between the germicide and the organic matter resulting in a complex that is less germicidal or nongermicidal, leaving less of the active germicide available for attacking microorganisms.
How does reducing the number of microorganisms that must be inactivated through meticulous cleaning increase the margin?
Reducing the number of microorganisms that must be inactivated through meticulous cleaning, increases the margin of safety when the germicide is used according to the labeling and shortens the exposure time required to kill the entire microbial load.
What are the factors that affect germicides?
The activity of germicides against microorganisms depends on a number of factors, some of which are intrinsic qualities of the organism, others of which are the chemical and external physical environment. Awareness of these factors should lead to better use of disinfection and sterilization processes and will be briefly reviewed. More extensive consideration of these and other factors is available elsewhere 13, 14, 16, 411-413.

Medical instruments with multiple pieces must be disassembled and equipment such as endoscopes that have crevices, joints, and channels are more difficult to disinfect than are flat- surface equipment because penetration of the disinfectant of all parts of the equipment is more difficult.
What are the factors that affect disinfectant activity?
Physical and Chemical Factors. Several physical and chemical factors also influence disinfectant procedures: temperature, pH, relative humidity, and water hardness . For example, the activity of most disinfectants increases as the temperature increases, but some exceptions exist.
Why is environmental disinfection important?
Therefore, environmental disinfection, hygiene habits, and the consequent maintenance of barriers are crucial in preventing infection from spreading. To develop effective policies and regulations to minimize the risk of transmission is strictly necessary to evaluate which organisms are present on the fomites.
Which bacteria are the most common endospore producing bacteria?
Among endospore-producing bacteria, the most common are the Bacillusand Clostridiumgenera [14]. Table 1reports several endospore-forming bacteria and their relative clinical manifestations.
Why should disinfection policies be based on risk assessment?
Disinfection policies should be also based on risk assessment to control cross-contamination while reducing the risk caused by exposure to infectious agents. The evaluation of the surface’s risks and type together with the nature of the pathogen agent(s) should lead to the use of an appropriate and effective antimicrobial agent. Such approaches must be learned by everyone since their implementation in the routine measure improves both cleaning performance and infection prevention [28].
Why should antimicrobials be limited?
However, as far as possible, the number of antimicrobials to be used should be limited not only for healthy and economic reasons but also to reduce environmental pollution. Not least, the discharge of waste biocides into the environment may promote the development of both biocide and antibiotic resistance [29].
What are the two layers of a bacteria cell?
Bacterial cells are generally surrounded by two concentric protective layers: an inner cell membrane and an outer cell wall [8]. The cytoplasmatic membrane shares a similar structure to the eukaryote’s one, but there are no sterols. Here, proteins involved in the energy production can be found like some respiratory chain protein as well as photosynthetic protein in photosynthetic bacteria that lack chloroplast. Among the proteins that constitute the cell wall, the main one is peptidoglycan (PGN), also known as murein, which provides rigidity to the structure and counteracts the osmotic pressure of the cytoplasm. PGN is characterized by a glucidic backbone of alternating units of two azotated carbohydrates, namely N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc). Each MurNAc is cross-linked to a short amino acid chain, which can vary with different bacterial species [9]. The differences in structural characterization of peptidoglycan define two morphological categories: Gram-positive and Gram-negative bacteria (Figure 2).
How do bacteria survive?
Another bacteria’s survival mechanism is the formation of biofilm: clusters of bacteria that are attached to a surface and/or to each other. During biofilm development, bacteria secrete extracellular polymeric substances (EPS) which are crucial to the production of an extracellular matrix [15]. This network maintains cohesion between cells and the surface and protects the accumulation of microorganisms against chemical, biological, and mechanical stressors. In this complex arrangement of cells, there are interstitial void spaces in which water flows so nutrients and oxygen diffuse [16]. As biofilm protects from harsh conditions and resistance towards antibiotics, it represents a serious global health concern. Furthermore, biofilm is involved in persistent chronic infections [17,18] and may potentially contribute to their pathogenesis [19]. In addition, some bacteria can produce a polysaccharide exocellular slime (the glycocalyx), which adheres to compromised tissue or the surfaces of biomaterials [20]. In fact, the glycocalyx is a fundamental factor in the persistence of infection linked to the prosthetic device.
What is the primary goal of disinfecting procedures?
The primary goal of disinfecting procedures is the inactivation of organisms on fomites. Generally, microorganisms belong to a diverse group such as bacteria, viral, and protozoan species [6]. These biological agents are widely found in the natural environment and, as a result, they can be found either in many work sectors or household contexts. The majority of these microorganisms are harmless; however, some of them or their metabolites may cause diseases. For example, the transmission of norovirus that causes nonbacterial gastroenteritis outbreaks is fomite-mediated as well as coccidioidomycosis. Furthermore, some of the greatest concerns regarding antibiotic-resistant bacteria transmission occur via fomite as reported by Julian et al. [7] for Staphylococcus pseudintermedius. Therefore, the knowledge of these organisms and their survival is fundamental to choose the right antimicrobial agents and implementing effective tactics.
What is the best disinfectant for hospitals?
