Infections are the result of invasion into the body of pathogens and the reaction of body tissues to these pathogens and their toxins. Only a small part of the many thousands of microorganisms existing in nature and is known to the present day, are pathogenic for humans. Other microbes living in the body, constitute the normal microflora, and their existence provides a natural resistance of the organism to pathogenic strains.
Infections continue to be a significant challenge of modern surgery in the same as it was in the past. The creation of new and more powerful antibiotics entails the emergence of new strains resistant to them pathogens.
Nosocomial infections are those which are passed previously infected patient due to hospital acquired infection. Such hospital-acquired infections can be caused particularly by the resident microorganisms as they exist in hospital acquired environment applications of broad-spectrum antibiotics. Among hospital-acquired staphylococcal infections remains one of the most frequent.
About autoinfection say in those cases when the agent becomes the germ pre-existing in the organism as a saprophyte. Alternative autoinfection is secondary iatrogenic infection related to, for example, with manipulation of a doctor or nurse, as the installation of bladder or winsniffer. Continue reading
Infectious disease prevalent worldwide caused by various microorganisms. “Infectious” disease known since ancient times, information about them can be found in the most ancient monuments of writing in the Indian Vedas, Ancient China and Ancient Egypt. Descriptions of some infectious diseases, such as dysentery, tetanus, erysipelas, anthrax, viral hepatitis, etc. can be detected in the writings of Hippocrates (460-377 BC). In the Russian Chronicles of the infection, described under the name of epidemic, endemic morovich diseases, emphasizing the main feature – mass, high lethality and rapid prevalence among the population. Described devastating epidemics and pandemics of infectious diseases. It is known that in the Middle ages was raging plague (“black death”), which died out a third of Europe’s population, and around the world from the plague in the fourteenth century killed more than 50 million people. During the First world war was the influenza pandemic (“Spanish flu”), which affected 500 million people, 20 million of them died. For a long time about the cause of infectious diseases were not known, believed that these diseases arise in connection with the “miasma” – poisonous exhalations of air. This teaching in the sixteenth century gave way to the doctrine of “contagia” (Trekstore).Infectious diseases – a large group of human diseases arising from effects on the body of viruses, bacteria and protozoa. They develop in the interaction of two independent biological systems of microorganism and of microorganism in the conditions of influence of external environment, and each of them has its specific biological activity.

Human health related to the quality of their food and metabolism in the body. Food can bring both benefit and harm – everything depends on what the nature of the effects on the body those substances that make up a particular product. Such diseases as cancer, also largely depends on what people eat, replenishing their energy reserves. Food is one of the major factors that can trigger the occurrence of malignancies, and represents about 40% of the total shares of carcinogenic effects. Products containing carcinogens entering the body, affect the chromosomal mechanism to activate oncogenes, which leads to the appearance of tumors. Experts say that the majority of cancer cases can be prevented just by eating the right foods. Research and experiments show that eighty percent of the disease can slow down or stop.
To the development of malignant tumors can lead to various reasons and factors. Specialists in Oncology say that about eighty percent of the cancer provoking factors and causes of tumours can be prevented.
What a person eats, certainly affects his health, and proof that eating habits play a significant role in the occurrence of tumors is the statistics of diseases of this kind in different geograficheskaia of the world where traditionally take a certain kind of products. Each type of cancer has a particular predominant geographical dislocation. For example, the far East – China, Japan, Korea – are rife with cancer of the stomach, in America and Europe, a high percentage of morbidity of male and female sexual organs, large intestine, while it is low in Southeast Asia.
