"Infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce."
A study of the microbial diseases that affect humans, animals, and plants, including the pathogenicity of microorganisms and the body's immune response to them.
Microbial Pathogenesis: The study of how microbes cause diseases in humans, animals, and plants.
Microbial Diversity: The study of the various types of microorganisms that exist, including viruses, bacteria, fungi, and parasites.
Immune System Response: The study of how the body's immune system responds to microbial infections and diseases.
Epidemiology: The study of the patterns, causes, and effects of microbial diseases in populations.
Diagnosis of Microbial Diseases: The study of methods used to identify and diagnose microbial infections and diseases.
Antimicrobial Agents: The study of substances or drugs that are used to kill or inhibit the growth of microorganisms.
Antimicrobial Resistance: The study of the ability of microorganisms to resist the effects of antimicrobial agents.
Vaccines and Immunization: The study of how vaccines work against microbial diseases and how immunization can prevent the spread of these diseases.
Hospital Acquired Infections: The study of infections that are acquired in a healthcare setting.
Bacterial Infections: The study of bacterial diseases that affect humans, including tuberculosis, pneumonia, and foodborne illnesses.
Viral Infections: The study of diseases caused by viruses, including HIV, influenza, and the common cold.
Fungal Infections: The study of fungal diseases that affect humans and animals.
Parasitic Infections: The study of diseases caused by parasitic organisms, such as malaria and toxoplasmosis.
Sexually Transmitted Infections: The study of infections that are transmitted through sexual contact, including gonorrhea, chlamydia, and syphilis.
Zoonotic Diseases: The study of diseases that are transmitted from animals to humans, including rabies, anthrax, and Lyme disease.
Bacterial Diseases: Bacterial diseases are caused by bacteria that invade the human body and cause illnesses. Examples of bacterial diseases include tuberculosis, strep throat, diphtheria, cholera, and syphilis.
Viral Diseases: Viral diseases are caused by viruses that infect human cells and replicate within them. Examples of viral diseases include the flu, cold, measles, HIV/AIDS, hepatitis, and chickenpox.
Fungal Diseases: Fungal diseases are caused by fungi that typically grow on the skin and inside the body. Examples of fungal diseases include athlete's foot, ringworm, candidiasis, and histoplasmosis.
Protozoan Diseases: Protozoan diseases are caused by single-celled organisms that can infect humans. Examples of protozoan diseases include malaria, amoebic dysentery, and Chagas disease.
Parasitic Diseases: Parasitic diseases are caused by parasites that live in or on the human body and cause infections. Examples of parasitic diseases include hookworm, tapeworm, Guinea worm disease, and schistosomiasis.
Prion Diseases: Prion diseases are caused by abnormal proteins that accumulate in the brain and cause degeneration of neural tissues. Examples of prion diseases include Creutzfeldt-Jakob disease and mad cow disease.
"An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection."
"Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses."
"Hosts can fight infections using their immune systems."
"Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response."
"Specific medications used to treat infections include antibiotics, antivirals, antifungals, antiprotozoals, and antihelminthics."
"Infectious diseases resulted in 9.2 million deaths in 2013 (about 17% of all deaths)."
"The branch of medicine that focuses on infections is referred to as infectious diseases."
