Although the vast majority of bacteria are harmless or beneficial, a few pathogenic bacteria can cause infectious diseases. The most common bacterial diseases include pneumonia, tuberculosis, and salmonellosis. Bacteria can often be killed by antibiotics, but some types are resistant to antibiotics and are therefore more difficult to treat.

Types of Pathogenic Bacteria[edit | edit source]

Pathogenic bacteria can be grouped into three categories based on their response to gaseous oxygen. These are:

Disease Mechanisms[edit | edit source]

Pathogenic bacteria cause disease in two ways: by invading tissues and by producing toxins.

Treatment[edit | edit source]

Treatment of bacterial infections usually involves antibiotics. However, the overuse and misuse of antibiotics have led to the development of antibiotic resistance, making some bacterial infections more difficult to treat.

Prevention[edit | edit source]

Prevention of bacterial infections can be achieved through good hygiene practices, vaccination, and the use of antibiotics when necessary.
