Infection: types, causes and differences (2023)

Infection: types, causes and differences (1)Sharing in Pinterest

As an infection spreads and its effects depend on the human body depends on the type of pathogen.

The immune system is aEffective barrierHowever, immune system capacity can sometimes overload disinfectant.

Some pathogens have little effect. Produces toxins or inflammatory substances that trigger negative bodily reactions. This variation means that some infections are light and barely notable, while others can be severe and threatening life.

The infection can spread in different ways.

Bacteria, viruses, fungi and parasites are different types of pathogens. They would see in different ways, including:

  • Size
  • Molde
  • occupation
  • Genetic content
  • How to react to the body

For example, viruses are smaller than bacteria. They enter a host and assume cells, while bacteria can survive without a host.

The treatment depends on the cause of the infection. This article focuses on the most common and mortal types of infection: bacteria, viruses, fungi and prions.

Viral infection

Virus infections occur due to virus infection. There may be millions of different viruses, but researchers only identified themselves5,000 typesExit. Viruses contain a small piece of genetic code and a layer of protein and lipid molecules protect them.

The viruses penetrate a host and join a cell. If it entered the cell, it completes its free genetic material. This material requires the cell to replicate the virus and the virus multiplies. New free viruses that infect new cells.

However, not all viruses destroy their host cells.Change the functionto cell.Human Papillomavirus (HPV)and the Epstein-Barr virus (EBV) can driveKrebsbe replicated by mandatory cells, without control.

A virus can also address certain age groups, such as babies or young children.

Viruses can remain resting for a period before multiplying again. The person with the virus may have recovered completely, but may be sick again if the reactive virus.

Viral infections include:

  • The cold, which occurs mainly due to rinovirus,Coronavirusy adenovirus
  • EncephalitismiMeningitis, result of enteroviros andHerpesSimplex -Virus (HSV) E West -nil -Virus
  • Wartand skin infections for which HPV and HSV are responsible
  • GastroenteritisWhich cause norovirus
  • COVID-19, a respiratory disease that develops according to a new coronavirus infection that currently causes global pandemic

Other viral conditions include:

  • It's ashi -Irus
  • HIV
  • Hepatitis 100
  • Polio
  • Influence (gloomy), including H1N1 pig influenza
  • Tu cheecy fry
  • Ebola
  • Middle East of Respiratory Syndrome (Mers-Cov)

Antiviral medications can help relieve the symptoms of some viruses while the disease occurs. They can prevent the virus from reproducing or increases the impact of the effects of the virus.

Antibiotics are not effective against viruses. This medicine does not interrupt the virus and its use increases the risk of antibiotic resistance.

Most treatments aim to relieve symptoms, while the immune system fights virus without support for medications.

Bacterial infections

Bacteria are unicellular microorganisms, also known as prokaryotes.

Experts estimate that there is at least1 without millionBacteria on earth. A no -Millons is 1, followed by 30 zeros. Most of the earth's biomass comprises bacteria.

Bacteria assume three main forms:

  • Spherical:These are known as Cocci.
  • Stang a form:These have the name of Bacilli.
  • Spiral:Ring bacteria are known as a spiral. If the coil of a spirit is particularly tight, scientists call it spirit.

Bacteria can live in almost any environment, from extreme heat to intensive cold, and some can even survive in radioactive waste.

There are billions of bacterial strains, and only some cause diseases in humans. They live in the human body, such as the intestine or in the airways without damaging.

Some "good" bacteria attack bad bacteria "and prevent diseases, but new bacterial diseases can be fatal.

These include:

  • Anger
  • diphtheria
  • Ruhr
  • bubonic plague
  • Tuberculosis
  • Typhus-
  • Typhus

Some examples of bacterial infections are:

  • Meningitis bacterial
  • Cola
  • lung infection
  • Tuberculosis
  • Upper respiratory tract infection (although this is usually viral)
  • Gastritis
  • Food poisoning
  • Ocular infections
  • Sinusitis(again frequent)
  • Urinary tract infections (Iitis)
  • Skin infections
  • Sexually transmitted infections (STDs)

A doctor can treat bacterial infectionsAntibioticsHowever, cleaning tribes become resistant and can survive treatment.

Fungal infections

A fungus is often aParasit mehrzelligerThis can decompose and absorb organic substance with an enzyme. However, there are individual cells such as yeast.

Fungi almost always reproduce the spread of individual cell spores. The structure of a fungus is usually long and cylindrical, with small branched filaments of the main body.

There are around of5.1 millionPilzart.

Many fungal infections develop in the upper layers of the skin and some are achieved for the deepest layers. Inhaled spores of yeast or mold can sometimes lead to fungal infections such as pneumonia or infections throughout the body. This is also known assystemic infections.

The body usually has a population of good bacteria that help maintain the balance of microorganisms. These pods, mouth, vagina and other parts of the body.

People at risk of developing fungal infection include people who:

  • Use antibiotics for a long time
  • have a weakened immune system that is, for example, in life with HIV or to liveDiabeteso Receivechemotherapytreatment
  • He sent a transplant because he takes medications to prevent his body from rejecting the new organ

Examples of fungal infectionsson:

  • Valley fever or coccidioidomicosis
  • Histoplasmosis
  • Candidiasis
  • Mushroom
  • Had
  • Some eye infections

An eruption can indicate a skin mushroom infection.

Prison disease

A prion is a protein that does not contain a genetic material and is generally harmless. Scientists do not classify prions as living microorganisms, but if a prion doubles in an abnormal way, it can become a dishonest agent and cause infection.

Prons can influence brain structure or other parts of the nervous system. They are replicated or not feed on the host.

Prions cause degenerative brain diseases that rarely, but quickly progress and are currently fatal.Creutzfeldt-Jakob disease (CJD).

investigatorAlso linkedsome cases ofAlzheimer diseaseFor prion infection.

Other infections

Although the forms of infection listed above are the main types, there are, but there are, but there areOthersThis can affect the body.

A single cell body with a nucleus can cause protozoa infection. Protozoa generally show similar characteristics, such as animals and can survive outside the human body.

In general, other people move through feces.

Multi cell organisms -larger cells are larger that tend to be visible in the expansion of growth to the mere eye. This type of parasite includes low worms and round speeds. This can also cause infection.

After all, ectoparasites, including mites, ticks, lice and fleas, can cause infections, connect or dig into the skin.

The cause of an infection is the type of organism that entered the body. A specific virus is, for example, the cause of a viral infection.

The effects of an infection such as swelling or race nose occur due to the experimental immune system to get rid of the penetrating organism.

A wound is full ofpusFor example, when white blood cells run to the site of an injury to combat strange bacteria.

The symptoms of an infection depend on the responsible body and the location of the infection.

Viruses are directed to specific cells, such as genitals or upper respiratory tractrabiaFor example, the virus points to the nervous system. Only the virus in skin cells and causes warts.

Others point to a larger cellular area, which leads to several symptoms.stomach ache.

A person with bacterial infection generally experiences redness, heat, swelling, fever and pain at the infection site, as well as swollen lymphatic glands.

An eruption may indicate a fungi infection in the skin. However, viruses and bacteria can also cause skin diseases and eruptions.

Frequent symptoms of prion diseases are the fastest use of brain damage, memory loss and cognitive difficulties.

There is not a single way to avoid all infectious diseases. However, people must take the following stepsriskTransfer:

  • Wash your hands frequently, especially before and after food preparation and after using the bathroom.
  • Clean the surfaces and prevent perishable foods from staying at room temperature for a long time when preparing a meal.
  • Receive all recommended and keep them updated.
  • Take only antibiotics with a recipe and complete the recommended course, even if the symptoms improve in an earlier stage.
  • Disinfect rooms that can have high bacterial concentrations, such as kitchen and bathroom.
  • Reduce the risk of sexually transmitted infections (STDs) that receive regular Ste controls that use or contain condoms.
  • Avoid sharing personal effects such as toothbills, combs, razor blades, beverage and kitchen utensils.
  • Follow a doctor's advice to travel or work while living with an infectious disease, since this can send the infection to others.

After an active lifestyle and a nutritionally balanced diet, the immune system can maintain strong and defend the body against various types of infections.
