Is Pneumococcus a virus? The common characteristics of viruses and pneumococcus are:

No. Pneumococcus pneumococcus is a type of bacteria that are classified into spherical, rod-shaped, spiral-shaped. Some spherical forms are a single ball and one bacterium, and some are dicoccus, that is, two spherical bacteria are connected together.

The simplest ones are: 1. Viruses do not have a cell structure, bacteria have a cell structure 2, and nucleic acids are RNA must be viruses.

Let's take a look at the difference between bacteria and viruses first.

1. Bacteria: a type of prokaryotes, the main feature is that there is no nuclear membrane, and its genetic material is scattered in a relatively fixed area within the cytoplasm, called the nuclear region. The outer edge of the bacteria is encased in a cell wall, which is usually formed by the polymerization of polysaccharides.

2. Virus: The structure is very simple, and there is a layer of protein on the outside, called the virus shell. The protein shell encloses the genetic material of the virus, which can be either DNA or RNA.

Viruses cannot complete metabolism on their own, nor can they complete reproduction, and need to parasitize in other cells to do so.

The vast majority of viruses and bacteria are not harmful to humans, and only a small part are harmful.

Some viruses are beneficial to humans, such as tobacco mosaic virus, which is a plant virus that infects plant tobacco leaves, and the infected tobacco leaves are embroidered with beautiful patterns. This virus is used for genetically modified research and is of great help to scientists.

There are also a lot of bacteria that are beneficial. For example, Escherichia coli parasitic in the human large intestine helps humans break down nutrients in food and can provide a variety of vitamins to the human body. Animals such as cattle and sheep are able to digest plant fiber because they have a bacterium in their digestive tract that breaks down cellulose; Without this bacterium, cows and sheep would not be able to graze.

At the same time, people rely on bacteria to produce medicines, food, feed, antibiotics, monosodium glutamate, seasonings, etc. At the same time, bacteria are also the decomposers of nature, decomposing animal feces, animal and plant corpses, etc. A world without bacteria is an unimaginable world, and all living things will not be able to survive.

Antibiotics only kill bacteria. For example, penicillin can destroy the polysaccharides on the cell wall of bacteria, so that the surface of the bacteria is exposed, and the bacteria lose their due protective effect, and the bacteria cannot survive. The outside of the virus is protein, and antibiotics have no effect on them.

But interferon can interfere with the replication of viral DNA or RNA, so that the number of viruses does not increase, and then rely on the body's own immune system to remove the remaining viruses.

In fact, it is easy to understand, except for lactic acid bacteria (in fact, it should be called lactobacillus), all other words with 'rod, ball, spiral, etc.) are bacteria, such as staphylococcus and tetanus bacillus. Except for the special phage, what are the viruses called, viruses have no cellular structure and must parasitize in living cells, while bacteria have a cellular structure. At the same time, it is important to remember that actinomycetes are not bacteria, they are prokaryotes.

Since it is a fungus, it is naturally not a virus.

Bacteria are much larger than viruses and have a complete cellular structure.

Bacteria have a cellular structure, and the difference between bacteria and eukaryotes is that there is no formed nucleus. But the genetic material is DNA.

The composition of the virus is relatively simple, consisting of proteins and nucleic acids (DNA or RNA), and Nguyen virus is a protein.

All have life! All of them are nutritious! will breed! It will make people sick!

a. Lactobacillus and cyanobacteria are both prokaryotes, and prokaryotic slow-band organisms do not have a formed nucleus, but both have a cell structure, a is correct;

b. Pneumococcus is a prokaryotic and does not have a formed nucleus, and bacteriophages belong to viruses and have no cell structure, and B is correct;

c. Yeast is a eukaryotic organism with a formed nucleus, c. error;

d, Chlamydomonas belongs to the eukaryotic lower plants, with a cell structure, d error disturbs Chang so choose: b Xinghui.

Typical pneumococcal pneumonia has a rapid onset, followed by chills, followed by high fever, and the body temperature can reach 39 410C; There is a dry cough in the early stage, and soon there is a small amount of mucous sputum purulent mucous sputum or typical rust-colored sputum, hemoptysis is rare, the general course of the disease is about 7 14 days, the situation improves quickly after the body temperature drops, the neutrophils increase in the onset period, Gram-positive diplococci can be detected in the sputum smear, the early ** course of the disease can be shortened, and the symptoms are mild. Old age and frailty

Malnutrition and other weakened resistance, due to poor resistance and strong bacterial virulence, can be complicated by sepsis, can also be complicated by bacterial meningitis, pericarditis, empyema, toxic pneumonia (shock pneumonia), not only pneumococcus can be caused, other toxin-producing bacteria, such as Staphylococcus aureus gram-negative bacilli and other serious infections can occur.

Pneumococcus, also known as Streptococcus pneumoniae, is a bacterium-shaped coccus that is often arranged in pairs. Diameter microns. For eye diseases caused by pneumococcus under the microscope, sodium hyaluronate eye drops, which are very sensitive, can be used as antibiotics**.

Pneumococcus is a genus of Diplococcus spp., which is a purulent gram-positive bacterium, round or lanceolate, without spores and flagella.

Pneumococcus facultative anaerobic bacteria, often residing in the nasopharyngeal cavity of normal people, most of them are not pathogenic, only some have the ability to cause disease, causing lobar pneumonia, peritonitis, pleurisy, otitis media, mastoiditis and sepsis. Microscopic pneumococcus pneumococcusFor eye diseases infected by pneumococcus, it can be used as an antibiotic with a very sensitive eye drop, "Strepto-pin sodium hyaluronate eye drops**.
