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 ache
Rash
Respitatory difficulties
Fever
Ear ache
Blocked sinuses
Tonsilitis
Conjunctivitis
Body odour
Paralysis
Joint pain
Vomiting
Diahorea
Stomach ulcers
Boils
Necrotic flesh
Bacteria can be very harmful to organisms. This is because bacteria can attack cells and cause sickness and diseases.
some bacteria produce toxins in their metabolism which is harmful for humans. if you have used antibiotics, the normal, good, bacteria that live in your body can be replaced by a pathogen, which will make you sick.
yes. some diseases such as cancer can be cured with harmful bacteria.
The word pathogenic means disease causing. So they can be harmful...but some pathogenic bacteria only are harmful to plants or dogs or cats, etc.
Some human diseases, such as erythromycin and tetracycline, are made by bacteria.
Probably to humans, I wouldn't eat dead leaves. Well yes you wouldn't eat dead leaves but in an eco way they are helpful.
Some bacteria are beneficial to humans, and some bacteria are harmful to humans.
some harmful effects of bacteria include: can cause decease's, sickness, unusual behavior in victim, spoil food. But there are many more.

Most bacteria are either harmless or beneficial to humans, but there are some that can cause harm. Many bacteria are able to cause disease and even death. For example, Clostridium botulinum can cause food poisoning that is sometimes fatal.

Yes. Most bacteria is not harmful to us such as bacteria in a yogurt, but some bacteria is harmful.
Bacteria may be harmful or helpful to humans. Some bacteria may cause lethal diseases when infecting humans, whereas others may be necessary to help maintain optimal health in humans (such as those in the small intestine which produce Vitamin K). Other bacteria help us with the production of various foods (cheese) and beverages (beer and wine).
Some viruses target bacteria or fungi, which can be harmful to humans. These viruses are called "bacteriophages" or sometimes just "phages".
Some microorganisms are part of the body's natural processes. For instance, the bacteria of your digestive tract help you to digest food. Other microorganisms can cause disease. Some otherwise beneficial bacteria can be harmful if they become too abundant.
