As you know, many bacteria cause disease. Moreover, these ailments have a number of features that distinguish them from other pathological processes. They are what make them unique.
Highlights
There are many characteristics of infectious diseases. First of all, it is necessary to single out such a characteristic feature for them as the possibility of transmission from one person to another. Because of this, they are considered among the most dangerous to human civilization.
Bacteria were thought to cause disease even before the microscope was invented. Then scientists assumed that some ailments were transmitted from person to person through very small, harmful creatures invisible to the eye. With the advent of the microscope, it was possible to prove this assumption.
How bacteria cause disease
Very much depends on how the infection entered the body. Many diseases caused by bacteria in humans are manifested by a violation of the activity of the organ that is closest to the place of penetration. The fact is that the body has many barriers andprotective means capable of suppressing/stopping almost any malicious agent. For this reason, perhaps the most common are respiratory infectious diseases caused by bacteria. The fact is that many microorganisms are transmitted by air and airborne droplets. As a result, the respiratory system becomes the first in the path of bacteria. Many infections damage the lining of the respiratory tract, causing coughing, runny nose, soreness, sputum production, and many other symptoms. The main ailments that develop in this way include: pneumonia, bronchitis, tracheitis, pharyngitis, laryngitis, rhinitis, tuberculosis and others.
Other bacteria cause disease after entering the bloodstream. Such infectious processes are extremely dangerous, as they often lead to the formation of sepsis. This disease is considered one of the most dangerous among all known to modern medicine. If the patient is not helped in the shortest possible time, then this can end very, very deplorably.
Recently, the number of cases of sexual transmission of infections has increased significantly. Here we should mention such ailments as chlamydia, vaginitis, salpingoophoritis, salpingitis and many others.
Bacteria cause disease most often by producing endotoxins and exotoxins, that is, indirectly. The nature of the disease that develops in the future largely depends onhow active and stable these harmful substances are.
Difficulties in treatment
Some bacteria cause diseases that are very difficult to treat. Even the most modern medicines are powerless against certain infectious diseases.
Besides this, one more feature of bacterial diseases should be noted. The fact is that over time, infections become resistant to the antibiotics that are used to destroy them. This process is especially fast in cases where people stop following the recommendations of specialists and arbitrarily change the antibiotic therapy regimen proposed by doctors. At the same time, incorrectly used drugs may not work the next time.
