I Am a Streptococcus Essay

Without the cells there will be no life. A cell is the the building block of the body. There 2 different types of cells there are animal cell and plants cells. Eukaryote is any cell that has a cell membrane bound. It also contains organelles.

The purpose of this lab was to save a little gummy worm named Sam from drowning. In addition, one of the labs key terms was a hypothesis which is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. Furthermore, we also learned that an independent variable is a factor that is changed during the experiment. On the other hand, the dependent variable is the factor that is observed or measured during the experiment. To begin with, the experiment the hypothesis formulated was if we reshape the paperclips into hooks and pick up sam, and the lifesaver (without touching them), then the lifesaver would be stretched enough for Sam to go through it.

So, somebody can make a certain observation and come up with a hypothesis about how and why a phenomenon occurs the way it is. Hypothesis could be

Cells are the basic units of structure and function in an organism, and Cells come only from the reproduction of existing cells.

There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life.

Bacteria are prokaryotic, and if you were to observe the two cells under a light microscope, you could distinguish their differences. The biggest distinguishment you can make while carefully observing the two cells, is the lack of a nucleus in a prokaryotic cell as compared to a eukaryotic. Prokaryotes also lack any membrane-bound organelles.

Streptococcus pyogenes, also known as Group A streptococcus (GAS), is a β-hemolytic, Gram-positive bacterium that most commonly causes respiratory disease, including pharyngitis or tonsillitis, as well as skin infections such as impetigo and cellulitis. The organism is transmitted via respiratory droplets or by contact with fomites, and commonly infects young children. In addition to the common clinical presentations associated with S. pyogenes, some individuals develop the postinfectious sequelae of rheumatic fever and glomerulonephritis. Due to the severity of these medical consequences, prophylactic antibiotic use is often recommended for any patients with otherwise mild S. pyogenes infections (21).

S. pyogenes infections may vary from mild to life-threatening with a plethora of symptoms due to the many types of infections it causes. This bacterium is responsible for the diseases of pharyngitis, rheumatic fever, impetigo, erysipelas, cellulitis, necrotizing fasciitis, acute poststreptococcal glomerulonephritis, and toxic shock syndrome, just to name a few. Each of these infections has its own unique set of symptoms as will be explored in depth below.

Well prokaryote is the name given to organisms that are made up from cells that lack a cell nucleus or cells that lack any membrane-encased organelles (a specialized subunit within a cell). In lamens terms, in prokaryotes, the DNA is not bound or held together inside a nucleus. Prokaryotes also only have a single loop DNA. Last but not least prokaryotes are divided into groups or domains but more about that in a minute.

Bacteria and Archaea are prokaryotic, which are mostly single-celled incomplex microorganisms. Both Bacteria and Archaea have a variety of prokaryotes classified in multiple kingdoms (Reece, et al., Campbell Biology, 2014). There are a number of scientists who believe that Archaea cells may be the precursor to Eukaryotic cells and that they have more in common with Eukaryotes than Prokaryotes (Madigan, Martinko, & Dunlap, 2009).

Streptococcus pneumoniae is found worldwide. The common host is the human body, in which it often does not cause disease but at other times it can cause diseses in particular, pneumonia. It also causes otitis media, bacteremia, meningitis, peritonitis, and sinusitis. The route by which this organism is spread is from human to human in the form of aerosol droplets. When inside the host the organism’s primary site of pneumococcal colonization is the nasopharynx. From this site it can aspire to the lungs, eventually spread to the blood and traverse the blood-brain barrier to the meninges, once inside the blood it can cause infections throughout the body. Symptoms of the disease include sudden

The cell is the smallest unit able to sustain life, and they are often referred to as the building blocks of life. There are two primary types of cell, which are categorized according to the way their genetic material is packaged, rather than size or shape. These are:

The gram-positive genus Streptococcus are among the normal flora found on the human skin and mucous membranes, Most streptococci are facultative anaerobes, some are microaerophilic, and others are anaerobic. The anaerobic streptococci are now considered within the genus, Peptostreptococcus. Most streptococci grow best at an incubation temperature of 35°C.

Life History and Characteristics: Staphylococcus aureus is a gram positive bacterium that is usually found in the nasal passages and on the skin of 15 to 40% of healthy humans, but can also survive in a wide variety of locations in the body. This bacterium is spread from person to person or to fomite by direct contact. Colonies of S. aureus appear in pairs, chains, or clusters. S. aureus is not an organism that is contained to one region of the world and is a universal health concern, specifically in the food handling industries.
