Some bacteria are photosynthetic, such as oxygenic cyanobacteria and anoxygenic green sulfur and green nonsulfur bacteria these bacteria use energy derived from sunlight, and fix carbon dioxide for growth other types of bacteria are nonphotosynthetic, obtaining their energy from organic or inorganic compounds in their environment. These were some of the examples of bacteria which are commonly studied in microbiology some known bacterial infections are bubonic plague, tetanus, cholera, leprosy, anthrax, and tuberculosis when a comparison is made between helpful and harmful types of bacteria, types of beneficial bacteria outnumber the pathogenic ones. Many human illnesses are caused by infection with either bacteria or viruses if the environmental conditions don’t suit the bacteria, some varieties morph into a dormant state they develop a tough outer coating and await the appropriate change of conditions infections – bacterial and viral. Antibiotic resistance is one of the most urgent threats to the public’s health be informed questions about bacteria, viruses, and antibiotics q: what are bacteria and viruses some bacteria can change their outer structure so the antibiotic has no way to attach to the bacteria it is designed to kill.
The flu, the common cold, warts, and cold sores are some examples a cold is an infection of the upper respiratory system colds can be caused by more than 200 different viruses. Bacteria or viruses can be passed on by touching or shaking hands with another person touching food with dirty hands will also allow viruses or bacteria from the intestine to spread. Antimicrobial resistance can occur in bacteria, viruses, fungi, and parasites below are some examples: tuberculosis (tb) : this airborne lung disease results from a bacterial infection.
Bacteriophage, also called phage or bacterial virus, any of a group of viruses that infect bacteria bacteriophages were discovered independently by frederick w twort in great britain (1915) and félix d’hérelle in france (1917. One of my favourite structures in biology is the type vi secretion system (t6ss), which is a membrane protein expressed on some gram-negative bacteria bacteria use these to transfer small molecules to adjacent cells but, structurally, parts of t. There are many viruses: dna viruses as for example the adenovirus (some of which can cause epidemic conjunctivitis), herpesvirus and pox viruses, and rna viruses as for example the picorna virus (eg hepatitis a), toga viruses (eg rubella), corona viruses (which can cause respiratory infection) and the retroviruses (eg hiv. Bacteria are very tiny organisms that fit into their own kingdom of life there are currently six different kingdoms of life: animals, plants, fungi, protists, eubacteria and archaebacteria the reason that bacteria fit into their own two kingdoms of classification is because of one unique.
Start studying biology bacteria and viruses learn vocabulary, terms, and more with flashcards, games, and other study tools -a process found only in some bacteria which removes n2 from the atmosphere and converts it to ammonia (nh3), for use by plants and animals example of contagious viruses: 1 immune cells in the body attacking. Virus - size and shape: the amount and arrangement of the proteins and nucleic acid of viruses determine their size and shape the nucleic acid and proteins of each class of viruses assemble themselves into a structure called a nucleoprotein, or nucleocapsid some viruses have more than one layer of protein surrounding the nucleic acid still others have a lipoprotein membrane (called an. There are some useful bacteria but all viruses are harmful antibiotics cannot kill viruses, but can kill most bacteria, with the exception of most gram-negative bacteria an example of a disease caused by bacteria is strep throat and an example of an affliction caused by a virus is the flu. A viral infection is any type of infection that is caused by a virus, which is even smaller than bacteria and is encapsulated by a protective coating, so it is more difficult to kill than bacteria viral infections involve a dormant virus getting into a living cell and re-writing the cell's genetic codes with its own.
Some bacteria have an extra circle of genetic material called a plasmid the plasmid often contains genes that give the bacterium some advantage over other bacteria for example it may contain a gene that makes the bacterium resistant to a certain antibiotic. Virus and bacteria virus - a virus is a capsule of protein that contains genetic material a virus cannot reproduce on its own it must infect a living cell to grow bacteria - bacteria are one-celled organisms that live on their own. For example, certain viruses attack cells in the liver, respiratory system, or blood in some cases, viruses target bacteria in some cases, viruses target bacteria diagnosis of bacterial and. For example, some viruses protect the host against other infections viruses also participate in the process of evolution by transferring genes among different species in biomedical research, scientists use viruses to insert new genes into cells.
Home » articles » list of human diseases caused by bacteria,virus,fungi,protozoa list of human diseases caused by bacteria,virus,fungi,protozoa important diseases and causative agents for exam study. Viruses are small infectious agents that hijack host cell's replication machinery to replicate inside a living host cell unlike bacteria (another infectious agent), it is debatable whether. Examples of pathogens include ebola, rabies, norvirus, rhinovirus and staphylococcus pathogens can be broadly divided into three groups: bacteria, viruses and fungi.
Bacteria and viruses can also be listed as “indicators,” which at a level outside of identified limits, may reflect “a problem in the treatment process or in the integrity of distribution system,” according to the epa. Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins bacteria are also used in making healthy foods like yogurt and cheese but infectious bacteria can make you ill. For example, viruses have some characteristics of life, like having genetic material, evolving over time through natural selection, and being able to reproduce by creating multiple copies of themselves.
