Causes And Consequences Of Streptococcus Pneumoniae

The colonies were smooth, translucent, and had a white brownish color. The Gram stain resulted in Gram positive cocci. After the Gram stain was completed, the bacteria were streaked on a Mannitol-Salt Agar plate and a Catalase test was performed. After these test were completed a Phenol Red Dextrose Fermentation tube was inoculated, and a SIM Tube inoculated.

The pathogen in the NPR story was called Klebsiella pneumoniae, which is a Gram-negative coccobacilli, relatively small, (0.5-0.8/ 1-2um), does not form spores, and is easily fixed. ("Klebsiella Pneumoniae Morphology") This pathogen is arranged either singly or in pairs and clusters, and can be cultivated on ordinary media. On agar media, the bacteria forms grayish-white colonies which

Streptococcus Pyogenes is a very diverse bacteria with effects ranging from nothing or a mild sore throat, to flesh eating disease, causing death in 40-60% of patients. The major and most common illnesses associated with this bacteria

Commonly referred to as strep bacteria.” (Streptococci and streptococcal Infections). Streptococci are normal bacterial residents on the skin and mucous surfaces outside or inside humans. Streptococcus contains a variety of species some of which cause disease in humans and other animals.

In the clinical setting it is found that when there is a bacterial infection that there is a sudden and rapid signs of illness in a patient. There will be dyspnea, hemoptysis, lethargic,

I decided to look at the bacteria Streptococcus for my paper. I chose this particular bacteria because my daughter just got over having strep throat and I have been told that I may be a carrier of it. Strep throat is caused by the bacteria Streptococcal Pharyngitis (Group A). I will tell you in this paper what the signs and symptoms, ways it is diagnosed, and treatment options are for group A streptococcus more commonly known as Strep Throat.

pneumoniae were EMB, Oxidase, Citrate, Gelatin, Glucose, Lactose, SIM, Methyl Red, vogues Proskauer and phenylalanine. The start of the Biochemical test consisted of inoculation on regular nutrient agar and incubating for 48 hours. After incubation, gram staining was done to identify the bacterium as either gram positive or negative along with the shape of the bacterium using a microscope. The bacterium was then inoculated on EMB based on the identification of it being gram negative. After the inoculation on EMB, Oxidase, Citrate, Gelatin, Glucose, Lactose, SIM, Phenylalanine, and MR-VP were inoculated and incubated for 5 days. The results of each biochemical were observed and

Streptococcus Pyogenes is a gram positive facultative anaerobic bacterium. It is also known as a beta-hemolytic group A streptococcus or Lancefield Group A streptococcus. Streptococci are round, spherical bacteria that grow in pairs or chains. Most microbiologists will say under the microscope they look like a string of pearls. S. Pyogenes is the most commonly associated with the strep throat. It is responsible for several other diseases as well as some post-streptococcal infections. The invention and advances made with antibiotics are greatly decreased the effects of Streptococcus Pyogenes.

“Streptococcus is a bacteria that infects the Immune System. The Immune System is made up of a network of cells, tissues, and organs that all work together to protect the body”("Immune Response"). According

Streptococcus pneumoniae is a bacterium pathogen that needs a host in order to survive, which are usually humans (Donkor, 2013). The bacteria is the cause of diseases such as pneumonia, meningitis, sepsis, and corneal ulcers. Some of the diseases S. pneumoniae causes are extremely harmful to humans and can even cause death in some cases (Mathos, Ferri, Figueiredo, Zangirolami, & Gonçalves, 2015). Humans, who already have a S. pneumoniae disease or have the bacteria simply in the upper part of the pharynx, transfers the bacteria through air particles, known as aerosols (Donkor, 2013; Lawrence, S. L. et al., 2015). In well populated areas or places, like schools, colleges, workplaces, S. pneumoniae is able to infect many humans

The genus Streptococcus is classified as a gram positive bacteria because of the spherical or ovoid cells that often arranged in pairs and the color it turns too after undergoing the gram staining technique. Unlike the catalase positive genus Staphylococcus, Streptococcus is catalase negative (Fox). Many Streptococcus bacteria are known to be facultative anaerobes, meaning they prefer to grow in places that have no oxygen but will adjust to places that contain some oxygen (Holt, et al.). On the contrary, there are a handful of Streptococcus bacteria that are considered to be obligate anaerobes, meaning they are strictly prohibited from being around oxygen because they are unable to live. Growing this type of bacteria includes specific factors

Streptococcus pyogenes is a very common bacteria found in humans. It is very transmissible and can be caught through the air via coughing or sneezing. This form of Strep. illness is referred to as Streptococcal pharyngitis, also known as Strep. throat, which can complicate into Scarlet Fever. It is also possible to be infected through abrasions of the skin, which can result in cellulitis, impetigo, or even necrotizing fasciitis. Aside from human to human contact, these bacteria can also be found in unpasteurized milk. There is no vaccine for Streptococcal infections, though antibiotics such as penicillin still work very well against them.

According to Woo and Wynne (2012) Streptococcus pneumoniae is the most common cause of pneumonia in all age groups (pg. 1281). In adult patients, 60 to 75 percent with a diagnosis of bacterial pneumonia, S. pneumoniae is the causative organism (Woo & Wynne, 2012). The goal would be to obtain a pretreatment culture and gram stain of sputum produced from the lower airways to validate that the antibiotic chosen is an effective choice (Mandell, Wunderink, Anzueto, Bartlett, Campbell, Dean, & .Whitney, 2007). However, a quality specimen is difficult to produce and the causative organism is noted as not identified in 50 percent of patients with this diagnosis (Woo & Wynne, 2012). With this information, the advanced generation macrolide azithromycin

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 clinical manifestations of pneumonia will be different according to the causative organism and the patient’s underlying conditions and/or comorbidities (Smeltzer, et al). Some of the manifestations are
