Bacteria

Living the Environment: Bacteria Abstract This experiment depicts the presence as well as the identification of various micro-organisms including the bacteria, fungi and algae which may be present on the surfaces that are commonly used. The use of scientific methods allows to check the presence of bacterial as well as fungal strains in this experiment. The hypothesis taken into consideration was that the Bathroom handle will contain more bacteria than the other surfaces. The experiment involved

titled “Test reveals antibiotic-resistant bacteria in a half hour” published on October 4, 2017 and written by members of the California Institute of Technology. The article is online so there are no page numbers. The article explains how many doctors will “often skip over first-line antibiotics like methicillin or amoxicillin” giving a stronger antibiotic to patients to ensure they will get healthy as soon as possible (“Test reveals antibiotic-resistant bacteria in a half hour,” 2017). Waiting two or

bars indicate oral samples. Faecal bars represent the mean and error bars the standard error (n=31), while oral bars represent the mean and error bars the standard error (n=99). The most common abundance of bacteria in faecal sample were Bacteroides and while the most common abundance of bacteria in oral sample were Streptococcus. The mean of abundance is obtained by summing up the abundance of each taxa and divide it by the total number of samples in each faecal and oral samples respectively. Standard

Nhavilay Wanda Nhavilay Professor W. Carlisle Microbiology Biol 2230 S05 28 November 2015 Tuberculosis the ancient bacteria Tuberculosis (TB) is one of the oldest recorded human diseases known to man, and is still the deadliest killers among bacterial infections (Smith). According to the World Health Organization (WHO), TB is believed to have killed more people worldwide than all the wars and famines combined. TB once viewed as a death sentence in the past, is now a preventable and treatable

Every person has bacteria that inhabit the skin and other body parts. Most of the bacteria are normal and not harmful to the individual. Certain types of bacteria inhabit different parts of the body because of the different resources the environment offers for the various bacteria. There are bacteria that thrive in the skin folds of humans because the moisture level and there is also a high salt level there, for example. The normal flora are opportunistic, and they need a way of entry in order

Bacteria are haploid organisms that lack the true nuclei of eukaryotic organisms. They contain one copy of each gene thus the genotype of bacteria can be deduced from phenotypes. Bacteria can reproduce asexually by means of binary fission and have the ability to transfer genes by several mechanisms: conjugation, transformation and transduction. Bacterial conjugation is a process that involves the transfer of genetic material between bacteria through a contact dependent process. The gene transfer

Introduction The purpose of this experiment is to investigate the effects of various household products may have on bacterial growth. The bacteria that was chosen as a test subject is Micrococcus luteus, which is generally considered a harmless bacterium unless the host has a weakened immune system. Among the household products that a set of groups will test are common cleaning and disinfecting products such as rubbing alcohol, Betadine, Germ-X, Neosporin, liquid hand soap, and Lysol cleaner.

prevent us from getting any worse. But what happens when our friends come across enemies they can’t defeat- in fact, they have no effect on? These enemies are what we call Superbugs. Superbugs are antibiotic resistant bacteria, which means that when we take antibiotics, there are bacteria that are immune to the drugs. Therefore, we cannot be helped in our time of need. We are stuck in a dilemma where we have been indifferent towards these superbugs when they’re what we need to focus on. The more we ignore

October 26, 2015 Sydney Hartman BIO 115 Section CJ Sydney Hartman BIO 115- CJ October 26, 2015 Hypothesis: There is a bacteria in pond 22 that is killing the fish. Methods: In this experiment, results were found by discovering the kinds of bacteria found in the given pond water samples. The first step in this experiment was to prepare the pond samples by completing serial dilutions of the pond water to the 10-4. We then had to prepare five separate plates by streaking the 10-4 dilutes. These

Introduction- This lab experiment serves as a model for community succession using bacterial colonies as the model. A bacterial colony grows from a single bacterium and is composed of millions of cells. Each colony has distinctive colony morphology: size, shape, color, consistency, and color. Community succession is a phenomenon observed in the organizational hierarchy of all living organisms. Community succession is not limited to bacterial colonies, but spans the entire community of life
