Bacterial Diseases


A bacterium or bacteria are very small unicellular organisms. They are smaller than human cells. Pathogenic bacteria reproduce at a fast rate in the body and produce toxins or poisons.  Inside the host body, the toxins cause cell and tissue damage and this results in the symptoms of the bacterial disease.

Examples of bacterial diseases are;

Vaccinations can be used to prepare the body’s immune system to protect against bacterial infections. Poultry are vaccinated against salmonella to avoid the spread of bacteria and reduce the incidents of the disease. Condoms can be used to prevent direct contact with gonorrhoea bacteria as a barrier method.

Antibiotics can be used to kill bacteria cells and treat bacterial infections.
