The agents and the spread of infection

To septic diseases need to include such inflammatory disease caused by bacteria belonging to the group of so-called pyogenic bacteria. Pathogens of these diseases often until recently was Streptococcus, rarely aureus and E. coli, still less of pneumophila, pneumococci, pathogens of flu, anaerobic microorganisms and other bacteria suppuration:
However, in recent years, due to the extensive and widespread use of antibiotics, Streptococcus as the cause of infection is less common, and aureus acquired greater importance, since there are antibiotic resistant and especially penicillin-resistant strains of staphylococci. Such infections as diphtheria and tetanus, are a particular group of diseases that cause toxemia (blood poisoning with toxins); in this case, although the infection is usually in the form of local process produced by these bacteria toxins so active that can cause the body to death.
An indispensable condition for the penetration of the above bacteria in the body is presence of wound surface. The last circumstance distinguishes them from agents of gonorrhoea, syphilis and tuberculosis, with the ability of penetration into an organism through the intact tissue.
Distinguish endogenous infection, when the infection is caused by bacteria that are already located in any area of the body (vagina, pipes, intestines, urinary tract, tonsils, carious teeth, and so on) and received the opportunity to spread into force of the prevailing conditions (birth, birth defects, trauma, operative intervention, and so on), and exogenous, when agents entered from the outside. Most often septic infection occur during the production of artificial abortions and when neasteptate the conduct of birth and the postnatal period ignorant persons.
In addition to cases of miscarriages and birth, the infection can penetrate into the sex organs during intercourse (breaks gimena, mucous membrane vagina), at various manipulations in the vagina (irrigation, introduction of mirrors, pessaries), if the latter are not enough aseptico and carefully. More dangerous in the meaning of infection are all kinds of surgical intervention, especially related to opening the abdomen. Finally, to the development of septic diseases can lead dead fibromatous node, twisted cysts, and subject to death and decay malignant neoplasms, in tissues are always developing pathogenic bacteria.
Ways of infection may be the following: 1) the spread along (per continuitatem), for example, when the infection spreads upward path (from the vagina into the uterus, tubes, pelvic peritoneum) or when out: bladder bacteria penetrate into the renal pelvis and later in the kidneys; 2) through the lymph system; 3) through the blood ways of Course, this division is conditional, as the spread of the infection is at the same time in different ways.
