A variety of particles make life in the human body, they can be positive as well as negative. Without a doubt, when investigating what types of organisms inhabit the body, their influence on well-being is understandable.
Presence of strange particles in the epidermis may be caused by a fungus or perhaps other alarming situations. In the following text, various aspects are explained.

The human body and types of organisms
The human body is a composition of various microorganisms. According to biological studies, the number of bacteria, viruses and fungi is a multiplication that results in billions. Although it is alarming to imagine containing a number of bacteria within the metabolism, some are focused on providing great benefits.
It is illogical to define all microorganisms as something malignant, causing diseases and complications in the body. When in reality they are a kind of protection, a barrier capable of controlling pathogens that seek to contaminate an organism.
Specifying where they are is to delimit their true trajectory, since the journey is quite extensive. Since they are mobilized by the largest organ, known as the skin. The inner organs is another favorite trajectory. In fact, they use saliva and feces to get around easily.
To better illustrate, it is useful to analyze what types of organisms inhabit the body, but applying examples. A common one is the white layer established in certain periods of time on the scalp, the product of a fungus. This microorganism is called Malassezia, responsible for producing dead plaques (dandruff), regularly. On the other hand, bacteria find a perfect place in the armpit area with every fluid from the apocrine glands.
Prokaryotic or bacterial cell
As stated above, microorganisms, especially bacteria, very frequently inhabit the epidermis. The spread of staphylococci is caused by contact with the environment, which is full of really polluting chemical compositions.
In the case of bacteria, when studying what types of organisms inhabit the body, we must relate it to the cells. Yes, these microorganisms are prokaryotic cells with free genetic material from bulky walls around them.
The adapted envelope, known as the cytoplasmic membrane, creates a thickness that depends on the type of bacteria, whether it is gram-positive or gram-negative. The cytoplasm is an area of proteins, which is evident in the presence of RNA to achieve a correct composition. In addition, there are other elements such as sulfur and lipids that require integration. As for the nucleus, it is round in appearance that houses a DNA chromosome inside.
Possible changes of a bacterium and its classification
Bacteria can carry out 3 genetic exchanges with two individuals. The phases experienced are different, identified as follows:
- Transformation: this phase instantly executes a bacterial destruction, that floating DNA is not completely eliminated. Another cell chooses it and proceeds to carry out a process of integration to its chromosome.
- Conjugation: the mechanism is developed with a particle as a donor that provides all the genetic content inside. In this sense, a recipient cell will capture this material, forming a relationship of different cytoplasms. The establishment of that union is characterized by remaining temporarily.
- Transduction: this process is motivated as a consequence of a previous virus, which causes an infection in the bacteria. As a result, the cell expels the component to another from the body.
Forms of bacteria, according to their morphology
- Bacilli: elongated formation.
- Vibrios: they maintain a figure with certain curves.
- Spirilums: in reference to their name, they have a wavy and spiral shape.
Coconuts: These are round in kind and with a variety of positions, such as:
- Couples (Diplococci)
- Aligned groups (Streptococci)
- Irregular masses (Staphylococci)
- Cubic masses (Sarcinas)
What types of organisms live in the body and what is the permanence of viruses
The impact caused by a virus on an organism is interesting. Over the years, medicine has focused on different analyzes to the point of being a complex specialty called Virology.
The negative effects are related to its composition, characteristic of something simple without enough enzymes. While it is true, they are made up of small particles of DNA or RNA that make up the nucleoid, these elements are of little relevance. Above all, without the ability to sustain or carry out the necessary processes of metabolism and reproduction.
Among the diseases caused by the virus, the following stand out:
- Flu,
- Shaking chills,
- Hepatitis,
- AIDS,
- Rubella,
- Measles,
- Different types of cancer.
In effect, the damages are initiated by the virus’ need to disturb other microorganisms to continue its progress. In some plant and animal cells, the virus attacks causing disorders, reducing essential functions.
This acellular organism is quite tiny in size, 10 times less than bacteria, requiring microscopes to observe it.
According to the capsid (protein structure) and each developed form, viruses tend to look like this:
- Cubic or icosahedral
- Polyhedral capsid
- Helicoidal
- Enveloped, lipoprotein membrane.
Scope of parasites
Knowing what types of organisms inhabit the body, it is mandatory to mention the classification of parasites. In short, they are microorganisms capable of producing different infections.
Protozoa
They tend to be incorporated into the human intestine, sliding through the fecal-oral route. In the case of blood, they are transmitted with mosquitoes.
Helminths
They are the well-known worms that make life in the intestine, destroying each nutrient generated.
Ectoparasite
It appears as lice or fleas in the body, initiating serious infectious diseases.
Common ailments caused by fungi
The fungi choose to develop in more visible places, developing abnormalities in the skin. For this reason, the heel, nails, hands and nose are constantly being affected.
Mushrooms are divided into:
- Saprophytes: organic matter feeding.
- Mycorrhizal: symbiotic process of plants.
- Lichenized: they result from fungi and algae.
- Parasites: originated from surfaces.
Scientific advances
Each species of microorganism in the human body is essential to achieve a positive life cycle. In the last decades, scientists have focused on discovering new life forms in microorganisms and thus obtaining great curative treatments.
