Yes, harmful bacteria are more of a problem now than 200 years ago due to various factors. This includes increased population density, global travel, and the misuse and overuse of antibiotics. These factors contribute to the spread and evolution of harmful bacteria, making them more difficult to control and treat.

What type of food properties allow harmful bacteria to multiply rapidly?
There are various food properties that allow harmful bacteria to multiply rapidly; one being the food is low in acid. Two more are moisture and that the food is high in protein.
Where do harmful bacteria usually live?
Harmful bacteria are bacteria capable of causing disease or injury to humans. We are surrounded every day by millions of bacteria, viruses, and other microorganisms, and many of them can become harmful under the right circumstances. Illness is a complex interplay between the host (you), the bacteria, and the environment. A change in any of these factors can result in disease. For instance, (arguably) the most famous bacteria in the world, Staphylococcus aureas, lives everywhere, but is typically found on your skin. Predisposed hosts (those with immune system diseases, immunosuppression, or problems with the body's most fantastic antibacterial shield - the skin) may become infected with this bacteria that everyone in the world has all over them by the millions. The real problem is finding out why some people are more susceptible to infection, because there really is nothing we can do about being exposed to these organisms. There are many more of them than there are of us.
How can drug resistance in bacteria be harmful to humans?
Drug resistance in bacteria can be harmful to humans because it can result in less effective treatments for infections. Higher doses may be needed to treat infections, and so treatment may have more risks. In some cases, antibiotics may no longer be effective at all.

What is the purpose of harmful bacteria?
There isn't really a "purpose" for harmful bacteria, or anything else, in the scientific sense (perhaps what you really meant to ask was "Why did God/the gods create harmful bacteria?" but then you should have put it in the Religion category). Some bacteria are "harmful" because that helps them spread and reproduce (bacteria that happened to cause coughing or sneezing spread more effectively, and so passed that trait on to their descendants). Some bacteria are harmful as a defense against other kinds of bacteria; a species that can live in a highly toxic environment has at least some incentive to MAKE the environment highly toxic so that they don't have to compete with other species. And some bacteria are harmful more or less "by accident"; they don't derive any real benefit from being harmful, but there's no advantage to them in NOT being harmful either, so there's no evolutionary pressure on them to become either more or less harmful.
Is bacteria harmful and helpful?
Yes. Your skin has many types of bacteria that are needed to fight off more harmful bacteria. Females have bacteria that help fight off fungal infections. When a bacteria population reaches a certain number it is no longer helpful, and thus considered pathologic
Is bacteria more helpful or harmful?
I'm sure you know that it can be both like the E.coli bacteria that lives in your colon is helpful, but if it grows uncontrollably you can develop a disease so i would say that they are more harmful than helpful
Why is a dog's mouth cleaner than a human's mouth?

Does fresh chicken become harmful if kept on room temperature whole night?
I believe it would become harmful bc illness causing bacteria could grow and multiply in that time.... such as salmonella. and do not refreeze it... i have heard that's even more harmful i feel smart.... im 12 years old and u ppl don't no this stuff
Can you refreeze a cooked ham that has been thawed but not warmed?
Yes you can. Generally when you warm it first bacteria settles into it and then when you thaw it once more to consume it, you will be eating the (sometimes harmful) bacteria.
When can microorganisms be harmful?
Almost every disease is caused by a microbe. Bacteria, viruses, amoeba, yeast plus many more.

What are the pro's and con's of commensal organisms as a defense mechanism?
Commensal organisms like bacteria on the skin make it more difficult for harmful bacteria to grow. However, the commensal organisms can be harmful to people with depressed immune systems. They could also cause inflammation if there are too many of them.
Are bacteria more harmful than virus?
No. Actually, it would be more accurate to say that you really can't compare the two; some bacteria and some viruses are harmless, some of each will make you sick, and some of each are deadly.
