Bacteriophages, also called phages, are viruses that kill bacteria. They do not kill humans, animals, or plants.
Bacteriophages are, therefore, the natural enemies of bacteria. In nature, both bacteria and bacteriophages are necessary to keep microscopic ecosystems working properly.
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic.
Probiotics are made up of good bacteria that helps keep your body healthy and working well. This good bacteria helps you in many ways, including fighting off bad bacteria when you have too much of it, helping you feel better. Probiotics are part of a larger picture concerning bacteria and your body — your microbiome.
Neutrophils provide the first line of defense of the innate immune system by phagocytosing, killing, and digesting bacteria and fungi.
In mouth, salivary lysozyme kills the bacteria whereas in stomach, hydrochloric (HCl) acid kills bacteria. Q.
Phagocytic cells such as macrophages and neutrophils play an essential role in the defense of our body against invading microorganisms. Invading microorganisms are ingested by phagocytic cells and subsequently found in membrane-delimited phagosomes, where they are killed.
Protection offered by the skin and mucous membranes
The closed surface of the skin and of all mucous membranes already forms a physical barrier against germs, which protects them from entering. Additionally, chemical substances like acid, enzymes or mucus prevent bacteria and viruses from gaining a foothold.
It is a myth that bacteria are killed at temperatures below 40 degrees. In fact, bacteria growth is slowed, but not stopped. The only way to kill bacteria by temperature is by cooking food at temperatures of 165 degrees or more. Bacteria also die in highly acidic environments like pickle juice.
An anti-inflammatory diet, regular exercise, good quality sleep, and probiotics are all strategies to put in place before trying antimicrobials or antibiotics to get rid of bad bacteria.
Boil. If you don't have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing germs, including viruses, bacteria, and parasites. adding a pinch of salt for each quart or liter of boiled water.
Bacteriophages are composed of proteins and a DNA or RNA genome that can be very simple, containing four genes, or complex, with hundreds of genes. The phages infect by injecting their genome into the bacteria which disrupts the bacteria's normal replication cycle.
Capsicums, including chilies and other hot peppers, are in the middle of the antimicrobial pack (killing or inhibiting up to 75 percent of bacteria), while pepper of the white or black variety inhibits 25 percent of bacteria, as do ginger, anise seed, celery seed and the juices of lemons and limes.
Keep cold food cold: it must be below 41° F (5° C) to slow bacterial growth and keep food safe. Keep hot food hot! It must be held above 135° F (57° C) to slow bacterial growth and keep food safe.
According to the Centers for Disease Control and Prevention, "Frequent handwashing is one of the best ways to prevent the spread of infectious diseases." Microbes are everywhere. They are on surfaces in your home, in your school, at your work, as well as on your body, including your hands.
The most ubiquitous example of a multicellular defence in bacteria is the formation of biofilms. Biofilms underlie a range of chronic infections and often form in response to antibiotics and competition from other strains79,80,81. They can render bacteria extremely hard to kill, for multiple reasons.
Vitamin C – Citrus Fruits & Greens
Consuming foods high in vitamin C such as grapefruits, oranges, tangerines, sweet red pepper, broccoli, strawberries, kale, and kiwifruit are thought to increase white blood cell production, which is key to fighting infection.
Bacteria in the natural environment are often found under nutrient-limiting conditions. To survive prolonged periods of starvation, many bacteria have developed starvation-survival strategies enabling them to persist in the environment until conditions become favorable for growth.
Most bacteria stop growing at a pH of 4.6. However, some species have been found to thrive at pH as low as 3.5. Hence, a pH lower than 3 is ideal for killing bacteria.
Prebiotics are non-digestible foods that stimulate the growth or activity of beneficial bacteria in the intestines. They essentially provide the food that the probiotics need to thrive. Examples are artichokes, leeks, onions, garlic, asparagus, bananas, legumes, honey, oats and lentils.
To disinfect, use an EPA-registered disinfecting product or a stronger bleach solution. Clean the surface with soap and water first. Always read the label of disinfecting products to make sure the products can be used on the type of surface you are disinfecting (such as a hard or soft surface).
