However, the amount of Staphylococcus aureus that is antibiotic resistance gradually increased, until the year of 1950, the number rose to 40% of the patients, and 80% of the patients until the year 1960. The mechanism that made the bacteria become resistant to the antibiotic is that, a mutation to an extremely small amount of Staphylococcus aureus. From this mutation the bacteria began to produce an enzyme called penicillinase, which it breaks the molecule within penicillin that makes the antibiotic to function. Consequently, this antibiotic become ineffective and the bacteria eventually survived. This kind of Staphylococcus aureus is called “MRSA”, referred to methicillin-resistant S. aureus.
Most food manufacturers use plenty of unhealthy and even suspicious ingredients in order to extend the shelf life of their food items. This means that you need to stay away from these toxic ingredients at all costs if you are to protect your health… Here are the top 10 offenders (not ranked according to the level of harm they cause): 1. Monosodium Glutamate ( MSG) MSG is an amino acid typically used to enhance the flavor of processed foods. It is well-known excitotoxin, which has been scientifically shown to negatively affect the nerve cells, overexciting them, and eventually leading to the point of cell death. Regular consumption of foods containing MSG damages a significant amount of brain cells, which may cause various neurological disorders.

Aerin Nortier Grade 11.2 Biology research project Introduction Bacteria are everywhere some harmful and others not, without bacteria the world would be nothing. In this research paper I will be discussing bacteria, anti-bacterial agents, pros and cons of bacteria and my conductive experiment on the growth and the killing of bacteria. Bacteria are single cellular organisms that most commonly reproduce through means of binary fission. They were first discovered by Anton Leeuwenhoek in 1676 and are classified as Monera in the five kingdom classification system. Anti-bacterial agents kill or inhibit bacterial growth.
Helicobacter pylori Cardiovascular Microbiology 212 research Supervised by: Dr.Muzaheed Abdul rasheed Zahra Dhiya Al-Ahmed 2170003019 CT | 2nd year Subtitle Page Number Introduction 3,4,5 Diagnosis 5,6 Breath Test 6 Blood Test 6 Stool Test 6 Biopsy 7 Transmission 7 Immune response 8 Symptoms 8,9,10 Treatment 10,11 Prevention 12 conclusion 12,13 References 14,15 Index Introduction Who does not have abdominal pain during childhood? predominantly, most people have this pain correspond to an infection. Many scientist and doctors count stress, increase the acidity, lifestyle, and spicy food as main causes of gastric infection while others relate it to bacteria. The first belief was the most supposed until two Australian physicians, Barry Marshall and Robin Warren before 1982 when bacterium was discovered, proved the opposite. They built a theory based on a specific type of bacteria called Helicobacter pylori (H. pylori) as one of results of stomach infection and they proved it.
Clostridium Difficile Clostridium Difficile (C. Diff) are known to be anaerobic rod shaped gram positive bacteria which are capable of forming spores. They are known to be the cause of millions of worldwide infections on a yearly basis. They are primarily acquired from hospitals, with incidences of such infections gradually increasing over the last 20 years. They are capable of causing potential life threatening cases of diarrhoea. Although they were discovered in the intestinal flora of new born babies in the 1930s, they were not recognised as a major cause of antibiotic associated diarrhoea up until the 1970s.
All told, there are around 100 billion E.coli on earth and live in rivers, lakes, forests and backyards. There are many dissimilar strains of E.coli and only a few cause illness. Those strains of E.coli which produce toxins knows as vero cytotoxins
Thus, the bacteria can use virtually any organic structure.  Bacteria as pathogens Although they are the smallest cells in biocoenosis, their role is even more important. Some bacteria are even able to assimilate (e.g. cyanobacteria or "blue-green algae"). Some of the bacteria decays or rots other organisms to feed themselves.
Counting the bacteria means determining the number of bacteria in a specific sample. There are many ways that we can use to count the microorganisms, one of which is the plate count. The plate count technique is used to count only the living bacteria by counting the number of colonies.Due to the large number of bacteria, and to be able to count it, the bacteria should be diluted several times and spread on an agar plate. In this way, colonies can be counted. These colonies are called colony forming unit (CFU).
