household spices/herbs such as cinnamon‚ cloves‚ mustard‚ ginger‚ and garlic‚ on the zone of inhibition in the Staphylococcus epidermis covered nutrient agar? Hypothesis: If 3 teaspoons of chopped cinnamon‚ cloves‚ mustard‚ ginger‚ and garlic steep in half a cup of boiling water for 15 hours and then placed in nutrient agar covered with Staphylococcus epidermis (gram positive) bacteria for 24 hours (in an incubator)‚ garlic will have the strongest antimicrobial effect. This is because of allicin

Bacteria Prac Aim: To observe the growth of bacteria on Agar plates Hypothesis: That the bacteria will grow in colonies throughout the agar plates except for the one with the anti-biotic loop because some will fight off the bacteria. Method: (Method taken from prac sheet) Plate 1: Use the swab to cover your entire agar plate in your bacteria. You only need one swab of bacteria but be careful to cover the entire surface of your agar in a layer of bacteria. Carefully place an Antibiotic Mastring

word “extreme”. The species of interest‚ Rhizobium leguminosarum‚ falls under the broad group of rhizobia‚ which are classified as nitrogen-fixing nodules that form on the roots of leguminous plants (Young and Haukka 1996). Rhizobium leguminosarum was the first discovered species of rhizobia‚ and is classified under the Rhizobiaceae family of the Rhizobium genus. This classification is all part of the alpha subdivision of Proteobacteria. Since rhizobia have such a broad range of organisms in it‚

Material Appendix B – Identifying Bacteria Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium‚ biochemical tests are used. PART ONE: GENERAL BACTERIA IDENTIFICATION Review the dichotomous

MIC 230 Unknown Identification Report The objective of this experiment was to identify an organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully

Gut bacteria Gut bacteria are bacteria that are located in the gut. The gut is considered as any part of the gastrointestinal tract. The gastrointestinal tract includes the stomach‚ mouth‚ oesophagus‚ and duodenum. The gastrointestinal track has many different parts and each part contains different bacteria.There are 100 trillion bacteria present in the human body‚ most of them can be found within the gut and others can be found in the mouth‚ skin surface‚ urogenital tract and nose.

Antibiotic Resistant Bacteria in Hospitals. Introduction Antibiotic resistant bacteria are bacteria who can survive after exposure to one or more antibiotics. Some bacteria present today can even be resistant to multiple antibiotics and these are sometimes referred to by the name Multidrug resistant (MDR). Today many clinically important bacteria are MDR’s and this is a direct result of past decades of antimicrobial use and misuse. If an infection results from this sort of resistant bacteria a stronger antibiotic
