example of an antagonist. It is a free-living fungus‚ commonly involved in root‚ soil and foliar environment which releases compounds that are essential in inducing localized or systemic resistance responses in plants. To test its efficacy to kill pathogens this experiment was conducted. Trichogramma is another natural enemy. It is an egg which parasitizes many pests commonly lepidopterous by killing them before they do the harm to the crop. It is augmented or release in the field. Agumentation can

Overview: The long term of this project is to know the price that resisting plants paid to be resistance against pathogens. Arabidopsis is the nominated plant for this research because it is the model plant that can be controlled. Also‚ it is the first plant that has the resistance gene that we are focusing on. This approach will be applied to other plants that have this resistance gene like tomato. Thus‚ the outcome of the resistance plants would be quantitatively measured and decided before applying

Our main goal was to test organisms’ resistance and susceptibility to bacteria‚ and whether the cell wall of bacteria exposed the membrane to pathogen or protect it from pathogens. I thought P. aeruginosa was gram-positive and therefore it would be susceptible. That was my hypothesis.We divided antiseptic agar plate into quadrants and divided antibiotics agar plate into six areas. We wrote the organisms’ name‚ date‚ and the temperature on the bottom of the agar plates. For antiseptic‚ our group used

possesses peritrichous flagella‚ making it actively motile. P.vulgaris occurs naturally the intestional tracts of humans and animals‚ soil‚ fecal matter‚ polluted water‚ and raw meat. It is grouped with the enterobacteriacea and is an opportunistic pathogen of humans. In humans P.vulgaris is known to cause urinary tract infections and wound infections. P.vulgaris is associated with nosocomial infection‚ and has the ability to degrade urea to ammonia by production of the enzyme urease.

The Search for Better Health 1. What is a healthy organism? Discuss the difficulties of defining the terms ‘health’ and ‘disease’ Health is a state of physical‚ mental and social well-being and not merely the absence of disease of infirmity. Disease is any condition that affects the proper functioning of a body. It is any disturbance of structure or function of the body of an organism generally associated with characteristic of symptoms and structural changes to the body. These

Freezing preserves food for extended periods because it prevents the growth of microorganisms that cause both food spoilage and foodborne illness. Freezing to 0 °F or below inactivates any microbes -- bacteria‚ yeasts‚ and molds -- present in food. Once thawed‚ however‚ these microbes can again become active‚ multiplying under the right conditions to levels that can lead to foodborne illness. Since they will then grow at about the same rate as microorganisms on fresh food‚ you must handle thawed items as

Cleaning areas such as bathrooms that are dirty and where bodily fluids are present may be more likely to be contaminated with pathogens. Handling laundry that may be dirty or contaminated with bodily fluids can also contain pathogens.
