#VIRUS BACTERIA PARASITE GAME FREE#
Temporary Parasites- These parasites spend only part of their lives as a parasite and another part as free-living organism.įacultative Parasites- These organisms are normally free living and infect a host only by accident.Ĭlostridium perfringens is a bacterium that causes infection and forms spores in adverse conditions. Obligatory Parasites- These parasites can only survive in a host and therefore go directly from one host to another. Spirillum: These are corkscrew or spiral shaped bacteria. Mycoplasma- They do not contain a cell wall and are either in a rod or in a sphere shape. Rickettsia- They behave like viruses and are responsible for typhus, Rocky Mountain Spotted fever and Rickettsialpox, a body rash. They are broadly divided in four categories:-Ĭoccus – They are spherically shaped and may live as standalone or pair up to form colonial structure.īacillus- They are rod shaped and also includes the bacteria that causes Anthrax. The structure differs from one another.įrom Greek baktērion, diminutive of baktēria 'staff, cane'įrom Greek parasitos meaning (person) eating at another's tableĪctobacillus, nitrogen-fixing bacteria, Bifidobacterium, Helicobacter pylori and Staphylococcusīacterial types vary by shape and size. Parasites are organisms that grow, feed, and shelter on or in a different organism. Most bacteria consist of a ring of DNA surrounded by cellular machinery, contained within a fatty membrane. It is important to mention that some scientists and researchers do not include single-celled organisms, such as Bacteria, Amoeba or Viruses that can cause disease, into the category of Parasites. Parasites generally do not provide any benefit to the host. The organism that is used by the parasite for the survival is known as the host. On the other hand, Parasites are organisms that grow, feed, and shelter on or in different organisms. They help in digestion and also keep the number of bad bugs under control. Some of them are harmful and some of them are beneficial, it all depends upon the type of bacteria. Bacteria are different from other cellular forms as they do not have any nucleus. On the other hand, Parasites are organisms that live in or on the hosts and derive their nourishment from the hosts.īacteria are single cell plant organisms and they are very small in size, measuring about a few microns in size (micron=0.001mm). They can be harmful as well as beneficial it depends upon the type of Bacteria. Key Difference: Bacteria are single celled and prokaryotic organisms.
