Some people tend to be prone to getting UTI ’s for various reasons‚ i.e. women after menopause because they have a decrease in estrogen ’s protective effects‚ some women are genetically inclined to UTI ’s because their bodies naturally allow harmful bacteria to attach to the sensitive lining‚ anyone recently catheterized‚ persons with

bacterial inhibitors abolish the most bacteria. In the future‚ people will choose the most effective bacterial inhibitor; therefore‚ they save both money and time. If the disinfectants are applied to the bacteria‚ then the zone of inhibition will increase because disinfectants are antimicrobial agents that are applied to non-living objects‚ and a petri dish is a nonliving

‘Superbugs’ Bacteria Bacteria are living organisms that can help the body and also cause infectious diseases. They are microscopic organisms and the largest is only 10 micrometres long (the same size as the world’s smallest guitar) the only living thing smaller than them is viruses. They can come in lots of different shapes and sizes. They grow and multiply every 20 minutes and are the same as the bacteria they came from‚ however they can sometimes mutate to adapt to their surroundings One

and many more because there is an unseen specimen called bacteria. Bacteria such as e-coli and staphylococcus are the most common bacteria that can cause illness to mankind. According to the World Health Organization (WHO) 3 out of 10 people are infected by bacteria that cause various diseases. This study was conducted to determine the anti-bacterial properties of duhat bark extract and it’s fighting ability against various types of bacteria. The bark of duhat is reported to have the capacity to treat

Pseudomonas aeruginosa Pseudomonas aeruginosa is the bacteria of my initial unknown project. Determining which bacteria I had was completed by many steps. The one fact that I had‚ was that it was a gram negative bacteria because on the gram stain it appeared pink. Its cell wall is composed of a plasma membrane‚ periplasmic space‚ peptidoglycan and an outer membrane (lipopolysaccharide and protein). By looking at the agar plate it was easy to tell that it was not a swarmer and it did not have any

genetic engineering and transformation of bacteria. The characteristics of bacteria are altered from an external source to allow them to express a new trait‚ in this case antibiotic resistance. In is experiment foreign DNA is inserted into Escherichia coli in order to alter its phenotype. The goal of the experiment is to transform E. coli with pGLO plasmid‚ which carries a gene for ampicillin resistance‚ and determine the transformation efficiency. The bacteria are transformed by a combination of calcium

times for bacteria vary from about 12 minutes to 24 hours or more. The generation time for E. coli in the laboratory is 15-20 minutes‚ but in the intestinal tract‚ the coliform’s generation time is estimated to be 12-24 hours. For most known bacteria that can be cultured‚ generation times range from about 15 minutes to 1 hour. Symbionts such as Rhizobium tend to have longer generation times. Many lithotrophs‚ such as the nitrifying bacteria‚ also have long generation times. Some bacteria that are

This means the people who have latent TB have no symptoms and are not contagious. 2) How is Tuberculosis caused? Bacteria cause TB‚ which is spread through the air. Areas‚ which are crowded‚ increase the likelihood of the bacteria spreading. This is because coughing; sneezing and breathing near an infected person can lead you to gain

Bacteria is everywhere inside and outside our bodies.Some are mostly harmless and some can be useful. Viruses. They are too small to see even by the eye. Cannot not muliply on their own so there fore need an host. They are capable of latching on to cells. We are often open to attack by them. Fungi Comes
