altered bowel movement following an increased water content‚ volume and/or frequency of stools. Infectious diarrhoea is usually linked to vomiting‚ nausea or abdominal cramps. When foreign bacteria‚ viruses or parasites enter the body‚ they cause infectious diarrhoea. Bacterial infections are caused by consuming bacteria‚ such as‚ Shigella‚ Salmonella‚ Escheria coli (E.coli) and Camylobacter via contaminated food or water. Many viruses such as rotavirus‚ norovirus and viral hepatitis can cause diarrhoea

are only dreams. One can dream all we like but without commitment‚ nothing can be achieved. Based on the article given‚ it proves that by devoting particular attention to pharmacodynamics‚ it enables one to understand the interaction between bacteria and antibiotics better. Such great understanding would then allow for manipulation of the drug usage‚ thereby strengthening our understanding of how to optimise antibiotic performance. Over the past decade‚ there have been numerous occasions where

GFP gene to be used to track the flow of genes between bacterial cells through conjugation. A plasmid with these qualities is necessary to create a plasmid that can be transferred to Gram-positive bacteria low in C&G (which are hard to transform with traditional means) by conjugation with other bacteria. Current vectors have the malR regulatory protein which imposes a problem because when active‚ the malM gene is not induced‚ so maltase is not utilized and the gfp gene is not expressed when maltose

Unknown Bacteria: Bacillus cereus Brittany Moy Coastline Community College Abstract Bacillus cereus is a Gram-positive‚ facultative aerobic‚ spore-forming‚ rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help

has be highlighted as very important‚ more so than it used to be as more and more people are suffering from heart diseases as a result of fatty deposits building up. Staying on the topic of food‚ the process of fermentation requires the use of bacteria which is a microbe. A big example of this is the production of bread which uses yeast to make the bread rise. This works as it is aerobic respiration so gives off carbon dioxide‚ making the bread rise. Another use of yeast is in anaerobic respiration

During the 1700s‚ microscopes were used to further explore on the microbial world‚ and by the late 1800s‚ the light microscope had been developed. “The electron microscope was developed in the 1940s‚ thus making the viruses and the smallest bacteria (for example‚ Rickettsiae and Chlamydia) visible” (Introduction to Microscopes‚ n.d.).

ABSTRACT: This project will show how strong certain bacteria that are commonly found in biofilms attract to Pseudomonas aeruginosa through a capillary tube. It will test ten bacteria to see which bacteria have more chemoattractants with Pseudomonas aeruginosa . These bacteria are all motile‚ so to come together to form a biofilm‚ they must lose their ways of mobility somehow. Since a biofilm is just one huge community of bacteria‚ it would be good to find out if there are ones that are more

What are the differences between spore and vegetative cell? 6. Bacteria vary in shape. Name the shape of bacteria that you learn. 7. What are the effects on food caused by spoilage bacteria and pathogenic bacteria? 8. What are the differences between eukaryote and prokaryotes
