Portion control strategies 2. Antiviral drugs are a class of medication used hreatment for treating viral infections. marcescensM. Ant-microbial, the treatmdnt Portion control strategies —literally "opposing life", from the Greek roots ἀντι anti"against" and βίος bios"life"—is broadly used to refer to any substance used against microbesbut in the usual medical usage, antibiotics such as penicillin are those produced naturally by one microorganism fighting anotherwhereas non-antibiotic antibacterials such as sulfonamides and antiseptics are fully synthetic.

Anti-microbial treatment -

Antibiotics and antifungals save lives, but their use can contribute to the development of resistant germs. Antimicrobial resistance is accelerated when the presence of antibiotics and antifungals pressure bacteria and fungi to adapt. Antibiotics and antifungals kill some germs that cause infections, but they also kill helpful germs that protect our body from infection.

The antimicrobial-resistant germs survive and multiply. These surviving germs have resistance traits in their DNA that can spread to other germs. To survive, germs can develop defense strategies against antibiotics and antifungals called resistance mechanisms.

Bacteria and fungi can carry genes for many types of resistance. When already hard-to-treat germs have the right combination of resistance mechanisms, it can make all antibiotics or antifungals ineffective, resulting in untreatable infections.

Alarmingly, antimicrobial-resistant germs can share their resistance mechanisms with other germs that have not been exposed to antibiotics or antifungals. This table gives a few examples of defense strategies used to resist the effects of antibiotics or antifungals.

Example: Gram-negative bacteria have an outer layer membrane that protects them from their environment. These bacteria can use this membrane to selectively keep antibiotic drugs from entering. Example: Some Pseudomonas aeruginosa bacteria can produce pumps to get rid of several different important antibiotic drugs, including fluoroquinolones, beta-lactams, chloramphenicol, and trimethoprim.

Example: Some Candida species produce pumps that get rid of azoles such as fluconazole. Example: Klebsiella pneumoniae bacteria produce enzymes called carbapenemases, which break down carbapenem drugs and most other beta-lactam drugs. Example: Escherichia coli bacteria with the mcr- 1 gene can add a compound to the outside of the cell wall so that the drug colistin cannot latch onto it.

Example: Aspergillus fumigatus changes the cyp1A gene so that triazoles cannot bind to the protein. Example: Some Staphylococcus aureus bacteria can bypass the drug effects of trimethoprim.

Alcohols also dissolve the lipid membranes that are present in microorganisms. Alcohols are cheap and effective antimicrobials. They are widely used in the pharmaceutical industry. Alcohols are commonly used in hand sanitizers, antiseptics, and disinfectants. Phenol also known as carbolic acid was one of the first chemicals which was used as an antimicrobial agent.

It has high antiseptic properties. It is bacteriostatic at concentrations of 0. They are active against a wide range of bacteria, fungi and viruses. Today phenol derivatives such as thymol and cresol are used because they are less toxic compared to phenol.

These phenolic compounds have a benzene ring along with the —OH group incorporated into their structures. They have a higher antimicrobial activity. These compounds inhibit microbial growth by precipitating proteins which lead to their denaturation and by penetrating into the cell membrane of microorganisms and disrupting it.

Phenolic compounds can also deactivate enzymes and damage the amino acids in microbial cells. Phenolics such as fentichlore, an antibacterial and antifungal agent are used as an oral treatment for fungal infections.

Trischlosan is highly effective against both gram-positive and gram-negative bacteria. Hexachlorophene Bisphenol is used as a surfactant. It is widely used in soaps, handwashes, and skin products because of its antiseptic properties. It is also used as a sterilizing agent.

Cresol is an effective antimicrobial and is widely used in mouthwashes and cough drops. Phenolics have high antimicrobial activity against bacteria such as Staphylococcus epidermidis and Pseudomonas aeruginosa. It is not used on the packing materials however. Ihloff and Kalitzki find a small but measurable amount remains in the skin of fruits processed in this manner.

They are highly effective against bacteria, fungi and viruses. Aldehydes inhibit bacterial growth by disrupting the outer membrane.

They are used in the disinfection and sterilization of surgical instruments. Being highly toxic they are not used in antiseptics. Currently, only three aldehyde compounds are of widespread practical use as disinfectant biocides, namely glutaraldehyde, formaldehyde, and ortho-phthalaldehyde OPA despite the demonstration that many other aldehydes possess good antimicrobial activity.

Microorganisms have a minimum temperature, an optimum, and a maximum temperature for growth. Different organisms show different degrees of resistance or susceptibility to heat or temperature, some organisms such as bacterial endospore are more resistant while vegetative cells are less resistant and are easily killed at lower temperatures.

This process involves the exposure to a temperature of degrees Celsius for an hour, on each for several days. Bacterial endospores can be killed using this method. Both dry and moist heat are effective in eliminating microbial life. For example, jars used to store preserves such as jam can be sterilized by heating them in a conventional oven.

Heat is also used in pasteurization , a method for slowing the spoilage of foods such as milk, cheese, juices, wines and vinegar. Such products are heated to a certain temperature for a set period of time, which greatly reduces the number of harmful microorganisms.

Low temperature is also used to inhibit microbial activity by slowing down microbial metabolism. Foods are often irradiated to kill harmful pathogens. Desiccation is also known as dehydration. It is the state of extreme dryness or the process of extreme drying. Some microorganisms like bacteria, yeasts and molds require water for their growth.

Desiccation dries up the water content thus inhibiting microbial growth. On the availability of water, the bacteria resume their growth, thus desiccation does not completely inhibit bacterial growth.

The instrument used to carry out this process is called a desiccator. This process is widely used in the food industry and is an efficient method for food preservation. Desiccation is also largely used in the pharmaceutical industry to store vaccines and other products.

These surfaces are especially important for the healthcare industry. Molecular dynamics simulation and time-lapse imaging are typically used to investigate these mechanisms. Osmotic pressure is the pressure required to prevent a solvent from passing from a region of high concentration to a region of low concentration through a semipermeable membrane.

When the concentration of dissolved materials or solute is higher inside the cell than it is outside, the cell is said to be in a hypotonic environment and water will flow into the cell. This plasmolysis and plasmotysis kills bacteria because it causes change in osmotic pressure.

Many diseases that once killed people can now be treated effectively with antibiotics. However, some strains of bacteria have become resistant to antibiotics. This is called antimicrobial resistance, also known as antibiotic resistance. Antimicrobial resistant bacteria are bacteria that are not controlled or killed by antibiotics.

They are able to survive and even multiply in the presence of an antibiotic. Most infection-causing bacteria can become resistant to at least some antibiotics. Bacteria that are resistant to many antibiotics are known as multi-resistant organisms MRO.

Some bacteria are also naturally resistant to certain antibiotics. For example, benzylpenicillin has very little effect on most bacteria found in the human digestive system gut. Antimicrobial resistance is a serious public health problem. The development of antibiotic resistance can be prevented by minimising unnecessary prescribing and overprescribing of antibiotics, the correct use of prescribed antibiotics, and good hygiene and infection control practices.

Some bacteria have developed resistance to antibiotics that were once commonly used to treat them. In the past, these infections were usually controlled by penicillin.

Rates of antimicrobial resistance are increasing across the world. Antimicrobial resistance is a major public health problem. The most serious concern is that some bacteria have become resistant to almost all of the readily available antibiotics.

This can make infections and diseases more serious and challenging and costly to treat. These bacteria can also spread from person-to-person. Standard precautions in hospitals are work practices that provide a basic level of infection prevention and control for the care of all people, regardless of their diagnosis or presumed infection status.

These precautions should be followed in all hospitals and healthcare facilities and include:. Implementing standard precautions minimises the risk of transmission of infection from person to person, even in high-risk situations.

Additional precautions also known as transmission-based precautions are used when caring for people who are known or suspected to be infected or colonised with highly infectious pathogens micro-organisms that cause disease.

Additional precautions are tailored to the particular pathogen and route of transmission. Additional precautions may include:. Antimicrobial resistant bacteria can also be passed from person to person within the community.

The Infectious Diseases Society of America Vegan iron-rich foods identified the Anti-microbiial and dissemination of treatmnet practice guidelines and other guidance documents as a top initiative in its Strategic Plan [3]. IDSA acknowledged that the ability to address rapidly evolving topics such as AMR was limited by prolonged timelines needed to generate new or updated clinical practice guidelines, which are based on systematic literature reviews and employ GRADE Grading of Recommendations Assessment, Development, and Evaluation methodology. Additionally, when clinical trial data and other robust studies are limited or not available, the development of clinical practice guidelines is challenging.
