The kingdom that consists of common bacteria that can cause illness is called Monera. This kingdom includes all prokaryotic organisms, primarily bacteria, which are single-celled organisms lacking a nucleus.
Within the Monera kingdom, there are numerous bacteria that are known to be pathogenic, meaning they can cause diseases in humans, animals, and plants. Some well-known examples include Escherichia coli, Salmonella, and Streptococcus. These bacteria can lead to a variety of illnesses, ranging from mild infections to severe diseases.
Understanding the role of the Monera kingdom in health and disease is crucial for developing antibiotics and vaccines and for improving food safety and hygiene standards.
