Essay on Bacteria

INTRODUCTION Bacteria are unicellular microorganisms too small to see with the naked eye that exist in virtually all environments in the world. They inhabit various environments such as dirt, water, and inside the human body (Bacteria, What, 2015). These organisms that have the capacity to live as either independent organisms or parasites (MedicineNet.com, 2012) are remarkably powerful and complex in nature as they can be both vital and detrimental to the health of an organism. As some bacteria are pathogenic

Bubonic Plague Rough Draft I chose this bacteria because we learned about it last year in Social Studies. I already had some knowledge about the bacteria so it stood out to me when I tried to think of a cell/bacteria/virus/ to write about. One thing I found interesting about the bubonic Plague was that i thought it was a virus but I saw something that said to use antibiotics if you get infected. I thought that was weird since antibiotics kill living things and viruses aren’t living, so I looked

E. coli, Bacteria (Domain), Proteobacteria (Phylum), Gammaproteobacteria (Class), Enterobacteriales (Order), Enterobacteriaceae (Family), Escherichia (Genus), coli (Species), is a gram-negative, facultative anaerobic, rod-shaped bacterium, with optimum growing temperatures at 37° C. This bacterium is commonly found in the lower intestines of warm-blooded animals. E. coli makes up about 0.1% of gut flora and most strains are harmless. Some are part of the normal gut flora and help their host by producing

Bacteria are unicellular organisms called prokaryotes. Viruses are pieces of biomolecules that cannot reproduce independently. Both groups may be pathogens, or may be beneficial- sometimes, the same species or variety may be both, depending on circumstances (Starr, C., and Taggart, R., 2004.) Throughout history, pathogens and more helpful species have played vital roles in the development of humanity as a species and of the human social arrangement. Prokaryotes are divided into eubacteria and archaebacteria

and rich, they also contribute the important roles in cold and high temperature ecosystem. Archaea: Extremophile Bacteria Bacteria Organisms that master the art live in most inhospitable environments Archaea is a group of single celled prokaryotic organism where they have lack of defined nucleus, it have the distinctive molecular characteristics that separating them from bacteria that are categorize more prominent group of prokaryotes as well as Eukaryotes that have defined nucleus and can be

1. There are many differences between bacteriophages and bacterium. Bacteriophages (also known as phages) are viruses that are obligate intracellular parasites, therefore, need a specific host in order to for this virion to leave its dormant state. The bacterium serves as the host in which the virus inhabits, allowing for it to grow and replicate. According to the case study by Kari Mergenhagen, the virus also obtains and enormous size compared to the bacterium. It has special structures, such as

of microbes. Some of the bacteria is capable of making humans sick. The study of microbes has become very important subject to help stop potential pandemics and ensure proper hygiene. Anthony van Leeuwenhoek was the first scientist who discovered bacteria. In my study of microbiology, I got to choose an unknown bacteria to identify. It is important to start off finding the family of the unknown bacteria and then eliminating one by one the species to know which bacteria it is. By knowing the family

1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized by different species of bacteria. INTRODUCTION: Bacteria biochemical testing can determine the types and numbers in terms of colony forming units of bacteria present in a sample of different

Hunting the Nightmare Bacteria documentary has had me paranoid. It’s scary to think foreign bacteria can enter your body and shut it down. The most informing information was the NDM-1 wasn’t a bacteria it was a resistance gene that can turn bacteria into superbugs. I do think antibiotics are being over used. I agree with M.D Arjun Srinivasan,” the more you expose a bacteria to an antibiotic, the greater the likelihood that resistance to that antibiotic is going to develop. So the more antibiotics

York Times, “We need to stop sanitizing everything and let bacteria back into our lives”. The assumption that all bacteria are harmful has driven people to adapt extreme sanitizing practises when in reality few are dangerous, and most have benefits in our lives [1]. Linder suggested people are now faced with a deficiency of healthy bacteria in their microbiomes and together we have contributed to the evolution of drug resistant bacteria. This does not suggest that the discovery of antiseptic practices
