6 in 60: Number 41 – Bacteria


Hello! A new month and I’m going to be going for a full complement of blogs this month, fingers crossed it comes off (I know last month was a little sparse). Anyway on to this months theme for 6 in 60! This month it’s all about bacteria! Let’s go!

  1. Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles.
  2. The control centre of a bacterial cell is a singular loop of DNA, some bacteria have extra loops of DNA and these are called plasmids.
  3. Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes).
  4. They produce oxygen! It has been said up to half of the oxygen in the atmosphere.
  5. Most bacteria are useful – gut bacteria produce vitamins and help people (and animals) digest their food, and bacteria in the roots help legumes (plants in the pea and bean family) get nitrogen out of the soil, which helps them to grow.
  6. Using antibiotics too often, or for diseases that don’t need them, like colds and flu (caused by viruses) can stop the antibiotics working (known as antibiotic resistance). MRSA (methicillin-resistant or Multiple-Resistant Staphylococcus Aureus) is a resistant form of a common bacterium found on the skin, which can cause infections after surgery.


The Sources

The first three come from microbiology online, there is a huge amount of information there for the keen microbiologist. The last three come from this website, had lots of other short facts if you were interested.
