What are probiotics? Probiotics are bacteria that help maintain the natural balance of organisms (microflora) in the intestines. An estimated 100 trillion microorganisms representing more than 500 different species inhabit every normal‚ healthy bowel. These microorganisms generally don’t make us sick; most are helpful. Gut-dwelling bacteria keep pathogens in check‚ aid digestion and nutrient absorption‚ and contribute to immune function. Probiotic therapies suggest that certain probiotics may help

The Gram Negative lab had two parts; the aim of the first part is to determine the concentration of gram negative bacteria in a water sample collected from a creek near Providence Road‚ Strickling. Gram negative bacteria have a cytoplasmic membrane‚ a thin peptidoglycan layer‚ and an additional outer membrane composed of phospholipids and lipopolysaccharides. Because gram negative bacteria have a relatively thin cell wall when compared to gram positive organisms‚ they are consequently unable to retain

classification of bacteria is important to make easier manipulation on the bacteria for various purposes such as for medical‚ research‚ developmental‚ and biotechnicalfieldsThe cell wall is the basis for classification of bacteria according to the Gram stain. Accordingto the chemical make up of bacterial cell wall‚ a staining procedure‚ Gram stain‚ helps usclassify bacteria into two subgroups‚ The cell wall can stain either positive or negative‚depending on its chemistry. If the bacteria stains positive

respiratory paralysis‚ muscular paralysis and even death. The paralysis is due to a release of a neurotoxin by the bacteria Clostridium botulinum. C. botulinum bacteria are typically present in soil‚ but can be present due to improper storage of commercially or home prepared canned food‚ preserves‚ and fermented foods. C. botulinum is rod-shaped and gram-positive (Solomon‚ Lilly 2001). The bacteria cannot be spread from contact with infected persons‚ and rarely can cause negative affects if inhaled or injected

substance being transmitted from one generation to another. For this experiment Griffiths used two types of pneumococcus bacteria (the bacteria that is responsible for causing pneumonia). He used the smooth strain (S) which had an outer capsule that acts as a protective shield from the host’s immune system and rough strain (R) which lacked the capsule. He then injected the S-strain bacteria into the mouse‚ as a result the mouse died due to the s-strain infecting it with pneumonia. When the r-strain was

University Biology 1510 Professor A. Hirons March 28‚ 2011 Abstract Antibiotic resistance is when microorganisms‚ such as bacteria‚ are able to survive an exposure to antibiotics and these bacteria are now resistant to the effects of these antibiotics. Antibiotic resistance in bacteria has been an issue since antibiotics were discovered. The fact that bacteria can become resistant to our medical treatments such as antibiotics is a natural evolutionary process‚ but there are certain human

Introduction to OTIPM The OTIPM promotes the occupational therapists use of a step-by-step occupation-centered reasoning process throughout all phases of occupational therapy. It guides occupational therapists to guide their practice in assessing‚ planning‚ implementing‚ and evaluating interventions for individuals who may be experiencing challenges in participating in meaningful activities‚ known as occupations due to physical‚ cognitive‚ behavioral‚ or environmental factors. In the OTIPM‚ there

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Superbugs are becoming a big problem in the world‚ but what are superbugs? Superbugs is a bacteria that becomes resistant to antibiotic drugs they carry genes that are resistant to antibiotic drugs and cannot stop the bacteria from multiplying (Staff 1). You might know of superbugs by the term multidrug-resistant bacteria. This mostly happens when people overuse antibiotics and their body becomes immune to those drugs. In very severe cases people with extremely weak immune systems usually die if

decided to do a project that revolves around bacteria. I was suggested to do a project where I get a petri dish containing my oral bacteria and see the effects of liquid on my oral bacteria. I was very curious about this topic and wanted to know how the bacteria grows so I gave it a shot. For my project‚ I was told to make an “if and then” hypothesis. My hypothesis was that “If I put orange juice on a petri dish containing my oral bacteria then the bacteria on the petri dish will multiply.” For this
