Your body is naturally full of microbes. However, these microbes only cause a problem if your immune system is weakened or if they manage to enter a normally sterile part of your body.
Microbes cause infectious diseases such as flu and measles. There is also strong evidence that microbes may contribute to many non—infectious chronic diseases such as some forms of cancer and coronary heart disease.
Different diseases are caused by different types of micro-organisms. Microbes that cause disease are called pathogens. To cause an infection, microbes must enter our bodies.
The site at which they enter is known as the portal of entry. An infection can be seen as a battle between the invading pathogens and host. How does the immune system work? Homepage Why Microbiology Matters What is microbiology? Microbes and the human body Microbes and disease. An infection is the invasion and multiplication of pathogenic microbes in an individual or population.
An infection does not always result in disease! Microbes can enter the body through the four sites listed below: Respiratory tract mouth and nose e. Gastrointestinal tract mouth oral cavity e. Vibrio cholerae which causes cholera. Urogenital tract e. Escherichia coli which causes cystitis. Breaks in the skin surface e. Clostridium tetani which causes tetanus. Immune system An infection can be seen as a battle between the invading pathogens and host. Routes of transmission Find out how you can pick up germs and pass them on to others.
Vaccination Just a shot in the arm — what do vaccines do? Antibiotics Antibiotics are powerful medicines that only fight bacterial infections. Powered by.
What to know about infections
About Blog Location. Leprosy 5. Pathogenesis is a multi-factorial process which depends on the immune status of the host, the nature of the species or strain virulence factors and the number of organisms in the initial exposure. Bacteria are classified into two main groups based on cell wall structure, which can be determined by a simple staining procedure called the Gram stain. As a result, some pathogens can invade a wide range of cell, types whilst others have a much more restricted invasive potential. Project Report on Human Diseases. Thus in the presence of protein, bacteria via bound complement with C3 receptors will be inhibited.

These infectious microscopic organisms are known as pathogens, and they can multiply quickly. Examples of pathogens include:. They can spread in several different ways, including through:. In this article, we explain the different types of infections, how to reduce the risk of infection, and what symptoms they cause.

Viruses are very tiny germs. They are made of genetic material inside of a protein coating. Viruses cause familiar infectious diseases such as the common cold , flu and warts. Viruses are like hijackers.
Bacterial disease , any of a variety of illnesses caused by bacteria. Until the midth century, bacterial pneumonia was probably the leading cause of death among the elderly. Improved sanitation, vaccines , and antibiotics have all decreased the mortality rates from bacterial infections, though antibiotic-resistant strains have caused a resurgence in some illnesses. In the early 21st century, tuberculosis , which is caused by Mycobacterium tuberculosis —several strains of which had developed resistance to one or more drugs widely used to treat the infection—was among the deadliest infectious diseases worldwide.
Infectious diseases are disorders that are caused by organisms, usually microscopic in size, such as bacteria, viruses, fungi, or parasites that are passed, directly or indirectly, from one person to another. Humans can also become infected following exposure to an infected animal that harbors a pathogenic organism that is capable of infecting humans.
Повисло молчание. Казалось, эта туша собирается что-то сказать, но не может подобрать слов. Его нижняя губа на мгновение оттопырилась, но заговорил он не. Слова, сорвавшиеся с его языка, были определенно произнесены на английском, но настолько искажены сильным немецким акцентом, что их смысл не сразу дошел до Беккера. - Проваливай и умри.
