What is the difference between microbes and viruses

These infections may be caused by the bacteria themselves or by toxins endotoxins they produce. Examples of bacterial disease include pneumonia , tuberculosis , tetanus , and food poisoning. Viruses can infect bacteria.

Bacteria are not immune to viral hijackers which are known as bacteriophages —viruses that infect bacteria. Image by Venngage Infographic Maker. Subscribe to America's largest dictionary and get thousands more definitions and advanced search—ad free!

Popular Categories. Pathogens are a subset of microorganisms that can cause disease and these include representatives of bacteria, fungi, viruses, helminths and protozoa.

Bacteria are prokaryotes—the smallest, simplest and most ancient cells, with free-floating genetic material. These microscopic single-celled organisms can be rod, spiral or spherical in shape. There are two types of bacteria: Gram-negative and Gram-positive.

The key difference is the presence of an extra outer membrane in Gram-negative bacteria. Bacteria are abundant in soil, inhabiting plant root systems to provide services like nitrogen fixing or acting as antifungal agents. Thermophilic heat-loving bacteria fix sulphur to produce sulphide and energy for photosynthesis in aquatic sediments or organically rich waters.

Dangerous bacteria also live in soil, a good reason to wear gardening gloves. The floods in northern Queensland in brought Burkholderia pseudomallei to the surface, bacteria which cause a serious infection known as melioidosis. In our bodies, bacteria inhabit the human digestion system, live on our skin and contribute to energy metabolism, digestion, brain function and general wellbeing. But if the balance of these bacteria is tipped by a dose of antibiotics or ill-health, then gut discomfort or skin infections are common.

Infectious diseases caused by bacteria have killed well over half of all humans who have ever lived on Earth. Historically, bacterial infections have started major pandemics such as the bubonic plague, which is estimated to have killed per cent of the population of Europe during the Black Death in the 14 th Century.

Bacteria reproduce mainly by binary fission—replicating their DNA so they have two copies on opposite sides of the cell, then growing a new cell wall down the middle to produce two daughter cells. This doubling time takes between 20 minutes and an hour. This short generation time allows mutations to emerge and accumulate rapidly and quickly cause significant changes in bacteria, such as resistance to antibiotics. Bacteria can communicate with one another by releasing chemical signalling molecules, allowing the population to act as one multicellular organism.

When bacteria and fungi cause infections, the illness is usually restricted to a local infection that affects a specific part of the human body.
