In the past, delimitation among pathogenic taxa was primarily based on morphological characteristics. Due to distinct species sharing overlapping characteristics, the morphological identification of species is often neither straightforward nor reliable. Hence, the phylogenetic species concept based on molecular...
What is a pathogen? Normal Flora Normal flora are the good microorganisms that live inside the gut. These microorganisms are not seen as antigens by the immune system, do not normally cause illness, and can actually help us to fight off pathogens. By competing for space and nutrients, natura...
The fact that pathogens mutate is also why we see special pathogens, pathogens/viruses which under normal conditions exist in animals, for instance, bird flu and swine flu. How scary is that? Bybear78— On Jan 26, 2011 There are relatively few fungi that are pathogenic to humans. However,...

Any organism or substance, especially a microorganism, capable of causing disease, such as bacteria, viruses, protozoa or fungi. Microorganisms are not considered to be pathogenic until they have reached a population size that is large enough to cause disease. Microbe A microscopic organism; a micr...
1. Are viruses cellular organisms? 2. What is the basic structure of a virus? What is the name of the bacteria that causes cholera? What group does the microorganism that causes the disease belongs to? ''Gangrene '' Groups: Gram-Positive Bacteria, Gram-Negative Bac...
The mouth is an organ in the digestive system that serves as the beginning of the alimentary canal and entry point for food being consumed. Here, the food is chewed into smaller pieces using the teeth and mixed with saliva containing the enzyme amylase to break down carbohydrates. Once the ...
Asepsis is a state of freedom from pathogenic microorganisms like bacteria,fungi, and viruses. It is not the same thing as sterility, where no such organisms are present, not even organisms not believed to be infectious. In medical settings, care providers use a number of procedures to create...
What is the response time for an innate cell to begin to mount an immune response after recognizing a pathogen? Describe the detailed steps about how a virus enters a host cell. Include the viral attachment and internalization. The synthesis...
The term immunity is defined as a condition where multi-cellular organisms are able to resist harmful effects or impacts of microorganisms. Immunity power can be variable with respect to different individuals. The more immunity power, the person or individual is more ...
