Streptococcus

Introduction Sepsis, meningitis, and pneumonia are all caused by Streptococcus pneumoniae, a gram positive pathogen. The majority of fatalities caused by Streptococcus pneumoniae are in children under five years and adults over sixty-five years. Unlike many other pathogens, Streptococcus pneumoniae is prevalent in both well- and under-developed countries. Antibiotics and vaccines are constantly being developed to combat Streptococcus pneumoniae, as new strains evolve and resistance increases.…

Streptococcus pyogenes The disease strep throat is one of the most common diseases for both children and teenagers. Some of the side affects of this disease include having a sore throat, swollen tonsils, and pain when swallowing . The pathogenic bacteria Streptococcus pyogenes causes this disease. Streptococcus pyogenes is in the phylum Firmicutes, the class Bacilli, the order Lactobacillales and the family Streptococcaeceae (Brenner, 2005). Streptococcus pyogenes natural habitat is the human…

Streptococci and Enterococci. The genus of streptococcus is streptococci and the genus for enterococcus is enterococci. The organisms most important in the group are streptococcus pyogenes, streptococcus pneumonia and Enterococcus faecalis. Streptococcus pyogenes is a common bacterium that causes strep throat, scarlet fever and skin infections. It is a Gram-postive, non-motile, non-sporeforming coccus that occurs in chains or in pairs of cells (Todar, 2012). Streptococcus pneumonia causes…

we begin to study the characteristics of Streptococcus mutans that enables them to be the main initiators of dental caries in human subjects. The human mouth contains hundreds of species of bacteria, some improve oral health while some do not. Streptococcus mutans is one of the worst of these bacteria. “Streptococcus mutans [does] have a prominent, well-documented role in caries etiology.”2 In this article we will discuss (a) the history of Streptococcus mutans, (b) how S. mutans gets into our…

This paper will will explore the way that Group A Streptococcus (GAS) pathogens invade and evade the immune system to cause infections that can be either innocuous or fatal. Group A Streptococcus is a group of human pathogens that are usually found in the throat or the skin (7). They can be spread through different direct contact to an exposed mucous membrane, or through contact to an open wound. The infections can be either non-invasive or invasive; invasive being the most dangerous and life…

Sydney Meyers Relative effectiveness of penicillin, neomycin and erythromycin on the inhibition of growth of Streptococcus pneumoniae Introduction: An approximate 1.1 million annual deaths worldwide are attributed to the to bacteria known as Streptococcus pneumoniae. Today, S. pneumoniae is among the most significant causes of bacterial disease in humans and remains to be one of the top 10 causes of death in the U.S (Hoskins, 2001). This pathogenic bacteria causes a variety of…

For this reflection, I’m going to specifically focus on the morphological unknown lab we used 2-3 lab periods for. Before going into lab, I started to create my own dichotomous key for all the microbial species we’ve been working on, assuming we’d have a species we previously worked on. My dichotomous key went from from gram stain to respiratory use and to fermentation results. I quickly realized that I shouldn’t have been working on this as my first go to. I mentioned in a past reflection that…

mycoplasmas, fungi, and parasites cause strep throat. Streptococcus bacteria may live in your throat or nose without causing any symptoms. In the winter most people actually have this bacteria in their nose or mouth and be healthy. These people are carries who do not have any symptoms nor spread the bacteria to other people. If these people become stressed or their immune system has been fighting a virus such as a common cold then the streptococcus bacteria may suddenly become harmful.…

HLTIN301C Assignment Q5a+b need answering 1. List and give a brief description of the four main groups of microorganisms. • Bacteria – A single celled organism that thrives in diverse environments. There are 5 groups that bacteria can be divided into (according to shape): bacilli, cocci, filamentous, spirilla and vibrio. Some are beneficially good for the body and others can be parasitic and produce toxins that can cause disease or death. • Fungi – A single celled or multicellular organism…

The disease of the integumentary system discussed in this essay is called Erysipelas. Erysipelas is a disease of the skin that causes lard raised patches of red skin that is usually on the face or legs, and coupled with severe fever and general illness. It is caused by a bacterial infection, and can be treated by antibiotics given to the patient by a doctor. There are a number of symptoms that can be attributed to Erysipelas. Typically, someone suffering from Erysipelas will develop a fever, a…
