Key Difference – Toxin vs Toxoid A toxin is a substance that is poisonous. Toxins are produced during the biological processes of living organisms. They are inherently toxic and immunogenic. Toxicity of the toxins can be altered or inactivated, and vaccines can be made from toxins to treat diseases; these are known as toxoids. […]
Difference Between Bacterial and Fungal Colonies
Key Difference – Bacterial vs Fungal Colonies Morphological characteristics are really important when characterizing bacteria and fungi. Colony morphology is a good method commonly used by scientists to identify and describe them. The colony characteristics of individual bacterial and fungal colony are carefully observed and used during these studies. Bacteria grow rapidly on nutrient […]
Difference Between Endotoxin and Enterotoxin
Key Difference – Endotoxin vs Enterotoxin A toxin is a poisonous substance that is produced by a living cell or organism. Toxins are produced by different types of organisms such as bacteria, fungi, plants, and animals. Bacteria are well-known microorganisms which produce toxins that cause severe diseases such as tetanus, cholera, and diphtheria. Bacteria […]
Difference Between Obligate Intracellular Parasite and Bacteriophage
Key Difference – Obligate Intracellular Parasite vs Bacteriophage A parasite is an organism which lives in and on another organism, deriving nutrients from them. Some parasites totally depend on the host organism while some are partially dependent. They are known as total parasites and partial parasites, respectively. Obligate intracellular parasites are one group of […]
Difference Between Germ Theory and Terrain Theory
Key Difference – Germ Theory vs Terrain Theory Many diseases are caused by infectious agents or germs. These infectious agents are referred to as microorganisms. The germ theory of disease states that diseases are caused by microorganisms. This theory was introduced and proven by many scientists. Among them, the great scientist Louis Pasteur scientifically […]
Difference Between Binary Fission in Amoeba and Leishmania
Key Difference – Binary Fission in Amoeba vs Leishmania Binary fission is the most common asexual reproduction method exhibited by prokaryotic organisms and single cell eukaryotic organisms. Binary fission results in two genetically identical daughter cells from a single mature cell. Most bacteria and single cell eukaryotic organisms depend on binary fission for propagation […]
Difference Between Nitrification and Denitrification
Key Difference – Nitrification vs Denitrification The nitrogen cycle is an important biogeochemical cycle in which nitrogen is converted into different chemical forms such as NH3, NH4+, NO2–, NO3– etc. There are four major processes in the nitrogen cycle. They are fixation, ammonification, nitrification, and denitrification. Many of these processes are carried out by […]
Difference Between Prions and Viroids
Key Difference – Prions vs Viroids Infectious particles cause diseases in plants, animals, and other organisms. There are different types of infectious agents such as bacteria, fungi, protozoans, viruses, viroids, prions, etc. Viroids and prions are small infectious particles which behave like virus particles. However, both types are structurally different from a typical viral […]
Difference Between Solid and Liquid Media
The key difference between solid and liquid media is that solid media contain agar while liquid media do not contain agar. That is, agar is a solidification agent in growth media, and solid media contain a solidifying agent while liquid media lack a solidifying agent. Further to this, related to usage, the difference between solid […]
Difference Between Nutrient Agar and Nutrient Broth
Key Difference – Nutrient Agar vs Nutrient Broth Microorganisms are grown on culture media. There are various types of media such as solid media, semisolid media and liquid media. These media are prepared according to the purpose of growing microorganism. The nutrient medium is prepared for growing bacteria in laboratories. It contains several ingredients […]
