each treated? A bacteria is a living cell organism that can survive inside our body and other non living objects as well. There are both good and bad bacterias and the good bacteria is known to helps fight against the bad bacteria that makes it's way into our bodies. According to a www.righthealth.com, less then 1% of bacteria is actually harmful to us. In fact, we couldn't survive without bacteria in our body. A bacteria infection is described as an imbalance of bacteria that can cause harm

Introduction Bacteria pathogens have become increasingly resistant to antibiotics. (Vuotto et al. 2014) The purpose of this experiment is to understand how bacteria are genetically modified in order to better understand the changes going on naturally in such bacteria. Genetic transformation is used in many sectors of everyday life. From agriculture to medical treatments, this biotechnology is allowing for new findings through science. Three methods of genetic transformation are projectile bombardment

can only be visualized by the aid of a compound-brightfield microscope. While we generally cannot see individual microorganisms with the naked eye, they are present in virtually every habitat known to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae, protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because they are small and because they infect cells. While most bacterial are unicellular they can also exist in colonial

that was not exposed to the pGLO plasmid that had Luria Bertani nutrient broth (LB) added, had lawn growth in all Petri dishes. This bacteria did not glow, the phenotype for the GFP gene, as the bacteria wasn’t exposed to the pGLO plasmid containing the GFP gene. Without the gene in the bacterial genome, the E. coli would be unable to express that phenotype. The bacteria also showed extreme growth in the form of a lawn. This is because the LB broth provided E. coli with the required nutrients and allowed

Unknown bacteria determined to be Alcaligenes faecalis because of its morphological, physiological and metabolic properties. In a laboratory setting, it often becomes necessary to identify an unknown organism. In this experiment, researchers classified an unidentified bacterium based on its physical structure, colony morphology, optimal conditions and metabolic properties. A Gram stain using crystal violet, iodine, and safranin and a simple stain using methylene blue characterized the organism’s

Lab Report: Unknown #1 Paola Rosales 302672960 Professor Youssef INTRODUCTION: Bacteria are the smallest living organisms, they are prokaryotic and have a simple cell structure. They do not contain a nucleus, and are unicellular. Bacteria are the most abundant microorganism. They are among the earliest forms of life that appeared on earth billions of years ago. They can grow in different temperatures and many exist naturally in our human flora, such as staphylococci. Growth within different

_____________ Can brushing your teeth kill you? There are many types of bacteria that can be found in your bathroom. They might also be found on your toothbrush! I have been researching about what bacteria are lurking in my bathroom. I placed 6 petri dishes filled with agar in my bathroom. I left them there for 24 hours to collect bacteria samples. Bacillus, Coccus, and spirillum are the three main kinds of bacteria. Bacillus are rod shaped. Cocci are spherical shaped. Finally spirillum are spiral

Mycobacteria are rod-shaped bacteria which require oxygen for growth. Each species has an acid-fast staining property during some stage of its growth cycle. It has thick, waxy, outer coating which can lead them to thrive in aquatic environments. For some time, scientists have known of bacteria that are similar to Mycobacterium tuberculosis, but that grow and act differently. When tuberculosis was a much more widespread problem and microbiology was much less able to tell the difference between similar

evidence that its bacterial component plays a role in the occurrence of chronic diseases [1]. In this regard, gastrointestinal tract (GIT) (or gut) bacteria are very important [2], being the niche for many bacteria which have been extensively studied [3]. Rather than the action of single or group of gut bacteria, perturbation of the overall gut bacteria (dysbiosis) is crucial for the integrity of the GIT and extra-GIT disorders [4]. The gut bacterial composition is influenced by both intrinsic and

Virus and Bacteria Virus - A virus is a capsule of protein that contains genetic material. A virus cannot reproduce on its own; it must infect a living cell to grow. Bacteria - Bacteria are one-celled organisms that live on their own. They can multiply and reproduce by subdivision Bacteria and viruses cause many of the diseases we are familiar with and may sound synonymous; they are greatly different from each other. [pic] o They differ greatly in size. The biggest viruses are only as large
