At Linnaeus University Centre for Ecology and Evolution in Microbial Model Systems (EEMiS) seven research groups investigates how microorganisms interact with each other and with other organisms in their environment. Seminars Time and Place: 13.00 in A137 (if not otherwise stated) 1-2 February EEMiS Workshop 21 February Room B221 March 7 Marielle van Toor (postdoc)…
Asymptomatic bacteriuria means you have bacteria in your urine but you have no symptoms of infection. If you are healthy, this condition is usually not a problem and not something that your healthcare provider needs to check for. However, it can cause complications if you are pregnant, have had a kidney transplant, or have certain other medical conditions. If…
With all the attention to the Ebola virus and other pathogens floating around in bodily fluids and the air, we may not be aware that the dirt beneath our feet is home to thousands of bacteria and other microorganisms. Even the soil in New York City, which we might think is somewhat lifeless given the preponderance of concrete and pollution, is as full of life…
Microbiology studies microscopic organisms and needs ways to distinguish different types visually. Microbiologists use staining procedures that add color to different types of organisms. These stains are chemicals that are of different colors, but these chemicals do not themselves stick to the organisms. Thus, a microbiologists adds a mordant to the stain. A…
In biology, there are four distinguishable types of microorganisms. These organisms are proven to be harmful or helpful to humans, plants and animals alike. A virus (singular) or viruses (plural) are a group of sub microscopic pathogens that can only replicate inside the living cells of organisms. Viruses infect all types of organisms, from animals and plants…
Earth could contain nearly 1 trillion microbial species, with only one-thousandth of 1 percent now identified, a new study suggests. To come up with the estimate, researchers combined microbial, plant, and animal community datasets from government, academic, and citizen science sources. Altogether, these data represent more than 5.6 million microscopic and nonmicroscopic…
Microorganisms are similar to more complex organisms in that they need a variety of materials from their environment to function and accomplish two primary goals-supply enough energy to manage their processes and extract building blocks to repair themselves or procreate. In addition to what they take in, microorganisms also thrive in particular environments…
Learning Objectives Summarize Koch’s postulates and molecular Koch’s postulates, respectively, and explain their significance and limitations Explain the concept of pathogenicity (virulence) in terms of infectious and lethal dose Distinguish between primary and opportunistic pathogens and identify specific examples of each Summarize the stages of pathogenesis…
As gut bacteria garner more attention every day, scientists are starting to make forays into uncharted waters: the microbes of marine mammals. The collection of benign bacteria living within our bodies, our “microbiota, ” helps us digest food, ward off infection, and has even been linked to mood and behavior. Research on microbial communities has branched out…
