pathogens - micro organisms that cause disease. all viruses are pathogenic but only some are pathogenic to man.
certain bacteria cause disease in man.
spoilage organisms - micro organisms that do not cause disease but they do spoil food by growing in the food and producing substances which alter the colour, texture, and odour of the food
E.G = souring of milk , mould on breads and rotting of fruits and veg
Pathogenic bacteria are harmful and can cause diseases in humans, while spoilage bacteria are not typically harmful but can degrade food quality by causing changes in taste, texture, and appearance. Pathogenic bacteria pose a health risk, whereas spoilage bacteria primarily impact the quality of food.

How to defrintiate between vibro cholera and pseudomonas aeruginosa?
The difference between vibrio and pseudomonase is that the pseudomonas are opportunistic pathogenic bacteria while vibrio are nonsymbiotic bacteria.
How can bacteria be both pathogenic and non pathogenic?
Bacteria can be both pathogenic and non-pathogenic depending on their characteristics and the host's immune response. Pathogenic bacteria have virulence factors that allow them to infect and cause disease in a host, while non-pathogenic bacteria do not possess these virulence factors and typically live harmlessly in the host or environment. The distinction between pathogenic and non-pathogenic bacteria lies in their ability to cause disease in a susceptible host.
What is the difference between pathogenic staphylococci from non-pathogenic strains?
Pathogenic staphylococci can cause infections in humans, while non-pathogenic strains do not typically cause harm. Pathogenic strains often produce toxins and enzymes that contribute to disease, while non-pathogenic strains lack these virulence factors. Additionally, pathogenic strains are more likely to be antibiotic resistant compared to non-pathogenic strains.
In an experiment DNA from dead pathogenic bacteria was transferred into living bacteria that do not cause disease These altered bacteria were then injected into healthy mice These mice died of the?
This experiment demonstrates the concept of transformation, where genetic material from one organism is taken up by another resulting in a change in phenotype. The injected bacteria likely acquired the pathogenic genes from the dead bacteria, causing them to become virulent and resulting in the death of the mice. This highlights the importance of understanding genetic transfer mechanisms and the potential dangers of gene transfer between organisms.
What harmful effects do some bacteria have on humans?
It depends on the type of bacteria.Although the vast majority of bacteria are harmless or beneficial, a few pathogenic bacteria can cause infectious diseases. The most common bacterial disease is tuberculosis, caused by the bacterium Mycobacterium tuberculosis, which affects about 2 million people mostly in sub-Saharan Africa. Pathogenic bacteria contribute to other globally important diseases, such as pneumonia, which can be caused by bacteria such as Streptococcus and Pseudomonas, and foodborne illnesses, which can be caused by bacteria such as Shigella, Campylobacter and Salmonella. Pathogenic bacteria also cause infections such as tetanus, typhoid fever, diphtheria, syphilis and leprosy. Bacteria can often be killed by antibiotics. They typically range between 1-5 micrometers in length.A few harmful effects of bacteria are:Head acheRashRespitatory difficultiesFeverEar acheBlocked sinusesTonsilitisConjunctivitisBody odourParalysisJoint painVomitingDiahoreaStomach ulcersBoilsNecrotic flesh
What is the difference between a pathogenic bacteria and a virus?
A pathogenic bacterium is alive while a virus is not.
What is the difference between pathogenic bacteria and non pathogenic bacteria?
"Pathogen" is something that gives rise to disease or infection. There are bacteria that do not do these things though, such as the culture in yogurt or the E.coli already residing in your stomach.
How to defrintiate between vibro cholera and pseudomonas aeruginosa?
The difference between vibrio and pseudomonase is that the pseudomonas are opportunistic pathogenic bacteria while vibrio are nonsymbiotic bacteria.
What was 'transformed' in Griffith's experiment?
In Griffith's experiment, non-pathogenic bacteria were transformed into pathogenic bacteria by being exposed to heat-killed pathogenic bacteria, a process now known as transformation. This led to the discovery of genetic material transfer between bacteria.
How can bacteria be both pathogenic and non pathogenic?
Bacteria can be both pathogenic and non-pathogenic depending on their characteristics and the host's immune response. Pathogenic bacteria have virulence factors that allow them to infect and cause disease in a host, while non-pathogenic bacteria do not possess these virulence factors and typically live harmlessly in the host or environment. The distinction between pathogenic and non-pathogenic bacteria lies in their ability to cause disease in a susceptible host.
How do you control spoilage rework and scrap?
what is difference between spoilage, rework and scrap
Difference between chemical spoilage and mechanical spoliage?
Example: a block of cheese has grown moldy. This is chemical spoilage. A block of cheese falls on the floor. This is mechanical spoilage.
What is the difference between pathogenic staphylococci from non-pathogenic strains?
Pathogenic staphylococci can cause infections in humans, while non-pathogenic strains do not typically cause harm. Pathogenic strains often produce toxins and enzymes that contribute to disease, while non-pathogenic strains lack these virulence factors. Additionally, pathogenic strains are more likely to be antibiotic resistant compared to non-pathogenic strains.
What is the difference between unicellular protoctists and a bacterium?
the difference between bacteria and protoctist is that the protoctist have a necleus while the bacteria don't.... in other words the bacteria is a prokaryotes and the protoctist is a eukaryotes
What is the difference between cyano bacteria and bacteria?
bacterias have plasmids. but cyno-bacteria haven't plamids.
What is the main difference between whales and bacteria?
Whales are big and bacteria are small
