common are Streptococcus pneumoniae, Haemophilus influenzae type b (Hib), Pneumocystis jiroveci. However, significant proportion of all pneumonia is caused by Streptococcus pneumoniae. In fact, the diseases caused by S. pneumoniae also include sinusitis, meningitis, otitis and some other problems, including septic arthritis, endocarditis and spontaneous bacterial peritonitis (WHO Pneumonia factsheet, 2013). The main aim of this paper is to familiarize the reader with Streptococcus pneumoniae and one
Streptococcus pneumoniae Life History 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
Streptococcus pneumoniae is a Gram-positive and fast-growing bacteria which inhabit upper respiratory tract in humans. Moreover, it is an aerotolerant anaerobe and usually causes respiratory diseases including pneumonia, otitis media, meningitis, peritonitis, paranasal sinusitis, septic arthritis, and osteomyelitis (Todar, 2003). According to Tettelin et al., more than 3 million of children die from meningitis or pneumonia worldwide (2001). S.pneumoniae has an enzyme known as autolysin that is responsible
My disease is Streptococcal pneumonia or pneumonia is caused by the pathogen Streptococcus pneumoniae. Streptococcus pneumoniae is present in human’s normal flora, which normally doesn’t cause any problems or diseases. Sometimes though when the numbers get too low it can cause diseases or upper respiratory tract problems or infections (Todar, 2008-2012). Pneumonia caused by this pathogen has four stages. The first one is where the lungs fill with fluid. The second stage causes neutrophils and red
Fungal pneumonia has many variations throughout the environment, including Coccidioides. Within Coccidioides, there are two species that are very similar. Coccidioides immitis and Coccidioides posadasii are two parasitic pathogens that affect the lung and can cause flu-like or pneumonia-like symptoms in mammalian bodies. Coccidioides is a pathogen that is part of the fungal kingdom (Taxonomy Browser). The separation of the species immitis and posadasii has been a relatively new discovery. The
Ventilator-Associated Pneumonia and Oral Bacteria Nelya Sirotinskiy and Danielle Davidson DHYG 221 Columbia Basin College February 9th, 2017 Ventilator-associated pneumonia (VAP) is one of the most common nosocomial infection associated with increased morbidity and mortality. It is recognized that 36-60% of all health associated infection-related deaths are attributable to VAP (Gupta et al, 2016). Ventilator-associated pneumonia is a lung infection that develops in a person who is on a
average of 5.2 days in the hospital. In 2013, it causes 2,596,993 deaths, it accounted 821.5 deaths per 100,000 populations, the average life expectancy was 78.8 years, and infant mortality rate was 5.96 deaths per 1,000 new births. For example, Streptococcus pneumonia causes 1,200,000 drug resistant infections per year, 19,000 excess hospitalizations, 7,000 deaths and $96,000,000 in excess medical costs per year
It is imperative to be aware when elderly has been diagnosed with pneumonia, depending on severity it is essential to treat and prevent it. Pneumonia is inflammation in lung result by infection, bacteria, fungi, and virus, and described as lungs with fluid or pus causing cough with phlegm. There are two categories of pneumonia for elderly that will be discussed, community-associated pneumonia (CAP), and healthcare associated pneumonia (HAP). Why older people are susceptible and high risk to pneumonia
species due to frequent mutation and horizontal gene transfer. Therefore, it is possible that the results obtained in our lab may vary from those provided in Bergey’s Manual. Arriving to the conclusion that the Gram negative bacteria was Klebsiella pneumoniae was much more direct. Using Bergey’s Flowchart for identification, the bacteria shared the test results and had a similar shape and
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
Staphylococcus aureus is a gram positive bacteria which on microscopic examination that appears in pairs, short chain, or as bunch grapes like clusters. (CDC. S. aureus) The symptoms of this bacteria is usually sometimes rapid or acute which is due to the induvial susceptibility amount of toxin, amount of contaminated food eaten, amount of toxin that is in the food digested, and also the general wellbeing of the human. On the other hand, Methicillin – resistant Staphylococcus aureus or MRSA is
Social models of health have become more relevant and continue to do so when compared to the old biomedical model for health over the last 150 years. World Health Organisation (WHO) (2014) depicts as the health problems in this age have shifted towards cardiovascular diseases, cancers, obesity from infectious diseases in the early 1900s such as pneumonia and tuberculosis models only focusing on the biological solutions have become less important than the social determinants of these diseases. A
considered under control with antibiotics, have invaded our hospitals and headlines with a vengeance. The vengeance used against us is caused by an existing organism called necrotizing fasciitis, the so-called flesh-eating bacteria, caused by Group A streptococcus. What this organism does is progressively destroy the human body tissue all the way to the bone. This organism has amazingly outsmarted us of even our most potent drugs. In our community right now, medical researchers are testing antibiotics that
History of Streptococcus Pyogenes Abstract: With the earliest recordings coming from the Fifth Century B.C., streptococcus pyogenes, and more frequently, its symptoms have been prevalent among doctors and historians for hundreds of years. The first mentioning of streptococcus pyogenes is to be credited to Hippocrates, in which he describes the relative symptoms of the flesh-eating bacteria in its early stages. Then depicted by Billroth in 1874, patients carrying erysipelas were determined to
Staphylococcus aureus, usually known as the ‘golden staph,’ is a very common pathogenic bacterium that is most commonly found on skin. [1] It is a Gram and catalase positive organism. It’s usually habitant is on the skin and a majority of individual’s noses and respiratory tract. S. aureus is one of the most important pathogen in today’s society as it can cause mild to severe infections amongst humans. S. aureus can enter the human body by a cut or severe scratch into the skin. According to Better
What microorganism causes this disease? The microorganism most likely responsible for Sarah's condition is Streptococcus. Specifically Group A Streptococcus, S pyogenes, otherwise known as scarlet fever. “Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains.” (Patterson, 1996) What is your diagnosis, and what features of the case were critical to your diagnosis? What she has is scarlet fever, characterized by the sandpaper-like rash from
Koch-week bacillus. This type of bacterium is gram-negative and rod shaped. Haemophilus means “blood loving”and therefore grow in chocolate agar which contains disrupted blood cells. Other bacterium which may cause Bacterial Conjunctivitis include Streptococcus and Staphlyococcus. The incidence of Bacterial Conjunctivitis caused by gram positive bacterium are more predominate. The different types of bacterium which cause Conjunctivitis are highly contagious and transmitted by face to face contact and
Introduction According to an online lab manual, Kirby-Bauer test is a highly standard test used in many labs for antibiotic susceptibility for many years. The use of this test is to determine the sensitivity or resistance of bacteria to antibiotics. It is a highly standardized procedure that makes use of Mueller-Hinton agar. For basic a bacterium is swabbed on the agar surface, and then antibiotic disc containing certain concentrations are placed on the center of a plate, pressed firmly so they don’t
When a sudden, inexplicable illness affects a child’s health, getting an accurate diagnosis, proper treatment and support can make all the difference. This has proven to be especially true in the case of two complex, related syndromes known as Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) and Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infections (PANDAS). Since 2012, pediatric rheumatologist Jennifer Frankovich, MD, and child psychiatrists Kiki Chang, MD
Necrotizing fasciitis is a bacterial infection that is very serious and sometimes fatal. This disease spreads very quickly and destroys soft tissue in your body. This disease is caused by multiple bacteria: group A strep, E.coli, Klebsiella (causes pneumonia), Clostridium (causes diarrhea), Staphylococcus (causes staph infections), and Aeromonas hydrophila (causes diseases in almost all organisms, hard to resist). The bacteria group A strep is the leading cause for necrotizing fasciitis. One of the
