of the symptoms. The study of meningitis dates back to the 1960’s when the causative organisms were discovered and treatments were developed. Since then the mortality rate from bacterial meningitis has not changed much despite the introduction of new antibiotics and treatments (Hussein 360). In the case of bacterial meningitis no one casual organism causes all of the cases‚ but rather there are many that capable of causing it. Although there are many causal organisms‚ there are three that are

huge amounts of energy‚ and their molecules are spread out as much as possible. With very little pressure‚ when compared to liquids and solids‚ those molecules can be compressed. It happens all of the time. Combinations of pressure and decreasing temperature force gases into tubes that we use every day. You might see compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Those are both examples of gas forced into a smaller space than it would want‚ and the gas escapes

The identification of an unknown bacterial environmental isolate through a series of morphological‚ physiological and differential exercises. The purpose of the environmental isolate report is to learn what is necessary in order to take an unknown environmental isolate (EI) and identify it. This was achieved through a series of exercises that provided information on the morphological‚ physiological and biochemical traits of the EI which were then compiled and interpreted in order to make a presumptive

Many of the bacteria that cause common bacterial infection are mutating and therefore gaining resistance. This means that the original antibiotics that were once used to treat these common illnesses are becoming increasing ineffective. This resistance delays treatment as the original antibiotics are ineffective. This can lead to the disease worsening and even death. This means that common illnesses that were once easily treated by antibiotics are no longer so easy to treat. This results in increased

Enumeration of Bacterial Contamination in Hamburger Meat from Unknown Sources C March 6‚ 2012 The importance of bacterial enumeration has become even more apparent in recent years due to the increasing numbers of harmful bacteria found in meat products. This process is the key to understanding the populations of microorganisms that contaminate the food supply. Much of the bacteria in meat has been shown to be resistant to multiple drugs; so disease-causing microbes

Geography internal 2.5B How does location affect vegetation growth? I will be looking at several factors that affect growth‚ such as density‚ height of plants‚ how different altitudes affects plant growth‚ temperature variations and wind speeds. All these are contribution factors that I assume will influence vegetation growth in the TVC. I discovered that all of the 6 sites that we visited had unique characteristics that made each one different. Some of the landscapes were baron and had very

The Effect of Varying Temperatures to the Rate of Respiration of Bufo marinus Statement of the problem: At which environmental temperature‚ do toads have the highest respiration rate? Most animals obtain oxygen‚ which comprise 21% of the air‚ from the environment. Oxygen combines with hemoglobin of the blood to form oxyhemoglobin. Oxyhemoglobin is transported to the tissues where oxygen is released and used for the metabolic functions of the animal. The functions produce waste materials‚ such

Economic growth is the overall growth in an economy. Gross National Product and Gross Domestic Product are the normal measures of economic growth. Because growth can come in many ways‚ GNP and GDP are not particularly good measures. More so‚ economic growth can occur from having more people in an economy. If economic growth occurs more slowly than the population growth‚ then there can be economic growth‚ but the average person is less well-off. As economic growth is measured as the annual percent
