The main difference between spore forming and non spore forming bacteria is the ability to form spores and other characteristics. Non-spore-forming bacteria are not pathogenic in general due to the absence of spores. They are pathogenic due to the formation of spores. Spore-forming bacteria are mainly Bacillus and Clostridium that form spores under unfavorable conditions. Some species of Bacillus, Clostridium, and Sporolactobacillus are spore-forming bacteria while most non-spore-forming bacteria belong to the families Enterobacteriaceae or Pseudomonidaceae. Spore-forming bacteria are generally pathogenic while non-spore-forming bacteria are not generally pathogenic. Most spore-forming bacteria are Gram-Positive while most non-spore-forming bacteria are Gram-Negative. Most spore-forming bacteria are tough while most non-spore-forming bacteria do not have tough walls. Spore-forming bacteria refer to bacteria that form spores under unfavorable conditions while non-spore-forming bacteria refer to bacteria that do not form spores. Both can be pathogenic under certain conditions.ĭifference Between Spore Forming Bacteria and Non Spore Forming Bacteria Definition.Spore-forming bacteria and non-spore-forming bacteria are two groups of bacteria classified based on the ability to form spores.Similarities Between Spore Forming Bacteria and Non Spore Forming Bacteria Most non-spore-forming bacteria belong to the family Enterobacteriaceae or Pseudomonidaceae.

This means that non-spore-forming bacteria are not active invaders. However, under stress conditions such as unusually high temperatures, poor food quality, crowding, and mechanical injury, they enter the tissues of the intestine and become pathogenic. Generally, they are non-pathogenic bacteria and they live in the intestine of animals and insects. Non-spore-forming bacteria are a group of bacteria that do not produce spores. Sporolactobacillus is a lactic acid bacterial genus and some spore-forming Sporolactobacillus are Sporolactobacillus dextrus, Sporolactobacillus inulinus, Sporolactobacillus laevis, sporolactobacillus terrae and Sporolactobacillus vineae.Clostridium is a bottle-shaped bacterium and some Clostridium that form spores are Clostridium botulinum, Clostridium difficile, Clostridium perfringens, Clostridium tetani and Clostridium sordellii.Some Bacillus species that form spores are Bacillus anthracis, Bacillus subtilis, Bacillus cereus, Bacillus clausii and Bacillus halodenitrificans.įigure 1: Bacillus subtilis Spore Staining Bacillus is an aerobic, rod-shaped bacterium.When revived, these bacteria can cause a number of diseases such as acute food poisoning, botulism, anthrax, and tetanus. Bacterial spores are resistant to sterilization, pasteurization, and antimicrobial treatments. A spore is a structure surrounded by durable protein coats. Some genera of Bacillus, Clostridium and Sporolactobacillus form spores. Spore-forming bacteria are a group of bacteria that can produce spores in response to unfavorable conditions such as extreme temperatures, desiccation, high UV irradiation, and enzymatic destruction. – Comparison of Key Differences Key Termsīacillus, Clostridium, Non Spore Forming Bacteria, Spore Forming Bacteria, Spores What is the Difference Between Spore Forming Bacteria and Non Spore Forming Bacteria

What are the Similarities Between Spore Forming Bacteria and Non Spore Forming BacteriaĤ. Spore-forming bacteria include some species of Bacillus and Clostridium while some non-spore-forming bacteria belong to the families Enterobacteriaceae and Pseudomonidaceae. Spore-forming and non-spore-forming bacteria are two types of bacteria classified based on the ability to form spores. Furthermore, spore-forming bacteria are highly pathogenic while non-spore-forming bacteria are not generally pathogenic. The main difference between spore forming bacteria and non spore forming bacteria is that the spore-forming bacteria produce highly resistan t, dormant structures called spores in response to adverse environmental conditions whereas the non-spore-forming bacteria do not produce any type of dormant structures.
