The word bacetria originates from the Greek "baktería", diminutive of "baktron" in the sense of "stick", for which a bacterium is a rod. Although it is true that bacilli present this form, other bacteria do not, as we will explain when talking about their classification.
They were the first living organisms to appear on Earth around 3.2 billion years ago. They are microorganisms belonging to the Monera kingdom that are also called schizomycetes, and are found in any terrestrial or aquatic environment.
Although their existence had been suspected since the Middle Ages, it was not until 1683 that the Dutch merchant , Anton van Leeuwenhoek, was able to observe them using a single-lens microscope that he had built, calling these microorganisms animalcules. It was in the year 1828, that they were given the name of bacteria by the German naturalist, Christian Gottfried Ehrenberg.
They are made up of a single prokaryotic rudimentary cell. They do not have a nucleus or plastids, but do have chromatin. Some have assimilating pigments. They are on land, in water, and in the air, and can generally move. Its size varies between 0.5 and 5 μm.
They can cause diseases and that is why they are called pathogens. Those that do not cause disease are called saprophytes. In some cases, they are even useful, as in the digestive processes or in the synthesis of vitamins.
They are used to treat wastewater, to make medicines and also edible products, such as cheeses, yigurs or vinegars.
Classification
Because of their shape, they are called cocci when they are steriform; bacilli if they are rod-shaped; spirils if their shape is spiral; vibrios, if they resemble commas. Their shapes vary according to the environment.
If they need oxygen to live they are called aerobic and if they do not require it anaerobic; if they are wrapped in a capsule, they are called capsulated, and anacapsulated, if they lack it.
Heterotrophic bacteria feed on organic matter: saprophytes feed on dead organic matter, producing its decomposition or putrefaction, and parasites feed on plants and animals to which they cause diseases, such as syphilis, tuberculosis , tetanus, typhoid fever, cholera, scarlet fever or diphtheria.
Autotrophic bacteria use inorganic salts to synthesize their protoplasm.
Reproduction
They reproduce sexually or asexually, in the latter case by bipartition, which is so rapid that it can produce millions of daughter bacteria in one day. Antibiotics are essential to fight bacteria that make the body sick.
bay concept
The word bay was born in reference to a town located in the Gulf of Naples "Baiae" whose name was put in honor of the helmsman of Ulises "Baios", a seaside area highly appreciated for its climate and vegetation, which 'popularized its name to spread to all similar forms of coastal relief.
A bay is born when a body of water penetrates generally by erosion, in the line of the coast. The body of water is surrounded by land. Many ports are built there, as it is a very suitable place for the protection of boats. When they are very large, they are called gulfs, although this is not very precise since in India, the Bay of Bengal is very large, and exceeds the extension of the Gulf of Mexico.
The Bahía de las Águilas is located in the Dominican Caribbean and stands out for its crystal clear waters, as well as having beautiful coral reefs.
Many localities bear the name of Bahia, as in Brazil one of its federative units, of great tourist importance , whose capital is San Salvador de Bahía. It has a great influence of African culture with a population of almost 14,200,000 inhabitants and an area of 567,295.6 km2.

In Argentina, and within the province of Buenos Aires, the important city of Bahía Blanca has around 300,000 inhabitants, being very thriving culturally, commercially and sportingly. In the province of Buenos Aires we also find the Bay of Samborombón, at the mouth of the Río de la Plata.
A number of 23 countries, with 29 bays in total, have formed the "Club of the most beautiful bays in the world", with attractive, emblematic and protected bays. This international association was born in Berlin on March 10, 1997.
In Botany, bays are dryland plants that can be found in Chile or the southwestern United States and are part of the Asteraceae or Compositae family.
balumbo concept
The word balumbo is not widely used, but its meaning is interesting , since it refers to large packages, not necessarily heavy. The term evolved from “balumba”, which originated from the Latin “volumĭna”, which is the plural of “volume” and is used to name things that bulk up or take up a lot of space. A balumba is a set of things that, added together, form a voluminous whole, and are also characterized by their disorder; while, a balumbo, can also be a single thing whose size is out of the ordinary. In general, one feels fatigued from lifting heavy things; but, in this case, what complicates or hinders is its excessive measure.
Being something very large, it is uncomfortable to store or transport, even if it weighs little, for example: "This balumbo does not fit in the trunk of my car, you must take some toys out of the bag, so that it can enter", "This mattress is an uncomfortable balumbo to carry, walking from your house to the mine, well, although it is not very heavy, I can't find a way to transport it without hitting anyone”, "This appliance is a balumbo, try to get a smaller one, for the same price and with the same functions", "I have a balumbo in my living room, with so many messy magazines”, “I don't like this balumbo that was made in my bedroom, with unused clothes, so I'll donate it and make room” or “It doesn't matter that you take that balumbo in the horse-drawn carriage, since what is detrimental to the horse is that the load is heavy and not its size”. In literature , "Balumba" is the title of a book by the Argentine writer and jurist, born in the province of Córdoba, Juan Filloy (1894-2000). It was published in 1933, his first book of poems being his, which caused a stir due to its erotic content.
