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
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.
Bacteria can be both harmful and helpful. Harmful bacteria can cause diseases in humans, animals, and plants. However, some bacteria are beneficial and play important roles in processes like digestion, nutrient cycling, and decomposition.
Humans carry a wide variety of bacterial species on their skin, in their mouth, gut, and other body sites. Some common bacteria found on or in humans include Staphylococcus aureus, Escherichia coli, and Bacteroides fragilis. These bacteria can have both beneficial and harmful effects on human health.
Mutations in bacteria that confer antibiotic resistance help the bacteria survive and thrive in their environment, but can be harmful to humans if these bacteria cause infections that are difficult to treat. Similarly, mutations in insects that confer resistance to pesticides help them survive, but can be harmful to humans as it makes pest control more difficult.
Bacteria can be harmful by invading a person's body and causing disease and even death. Bacteria can also lead to food spoilage, which negatively impacts someone's food supply at best and causes illness at worst.
Some bacteria are beneficial to humans, and some bacteria are harmful to humans.
Bacteria can cause harmful effects in the body by producing toxins that can damage cells, tissues, and organs. They can also trigger inflammatory responses leading to symptoms such as fever, swelling, and pain. Some bacteria can even cause serious infections that may be life-threatening if not treated promptly.
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.

Some common harmful bacteria include Escherichia coli (E. coli), Salmonella, Streptococcus pyogenes, and Staphylococcus aureus. These bacteria can cause various infections and illnesses in humans.

Yes. Most bacteria is not harmful to us such as bacteria in a yogurt, but some bacteria is harmful.
Archaea are not known to cause harmful effects in humans. However, some archaea species can be pathogenic to certain animals or plants. Additionally, archaea can contribute to global warming through their production of methane gas in anaerobic environments.
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 harmful effects of humans on land include deforestation, pollution from industrial activities and agriculture, soil erosion, habitat destruction for development, and littering. These activities can have a negative impact on ecosystems, biodiversity, and overall land health.
