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
Necrotizing Fasciitis (flesh eating bacteria ) from an essay by Katrina Tram Duong, edited by S.N. Carson M.D. Necrotizing fasciitis, known commonly known as "flesh eating bacteria [infection]", occurs in a wide range of people 1. It occurs in the elderly, middle aged and younger patients. It occurs in athletes and debilitated individuals. It can occur in drug abusers with self inflicted wounds and healthy individuals with incidental injuries. It may occur in those with metabolic disorders such

Acute Morphology of Streptococcus pyogenes Abstract: Streptococcus pyogenes is a gram positive coccus bacterium that is extremely common bacteria. This bacterium is part of group A streptococci, which meant that it has a certain type of polysaccharide antigen on its cell surface. It is commonly known as pharyngitis, or strep throat and produces over twenty exotoxins. Even though this bacterium has been around for thousands of years it still has a susceptibility to penicillin and there have only
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
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 have this certain bacterial infection. In 1883, the chain-forming bacteria were isolated by Fehleisen; and in the following year, Rosenbach applied the S. pyogenes name. Further advances in hemolytic and non-hemolytic studies were made by Lancefield in the 1930’s, in which the alpha
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
Streptococcus equi equi Introduction Streptococcus equi equi is small non-motile, translucent cocci found in chains or pairs bacterium. It is commonly known as strangles. Strangles is one of the most common worldwide and highly contagious infectious respiratory diseases affecting horses, mules, and donkeys. Aside from inside of carrier horses, Streptococcus equi equi have the ability to live in the environment for four weeks. The survival of Streptococcus equi equi depends on the humidity and

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, and Margo Thienemann, MD, have been evaluating and treating children in our PANS service. Here they describe these syndromes and
once 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
Rheumatic fever is a disease that can occur following bacterial infection with Group A Streptococcus. Predisposing infections also include strep throat tonsillitis and skin infections, such as impetigo, caused by Streptococcus pyogenes. Overall, rheumatic fever is rare in Australia; however, the rate of rheumatic fever amongst Indigenous Australians is much higher. Rheumatic fever is a serious condition that can lead to long-term complications, such as rheumatic heart disease. Causes & Pathophysiology
nodules over the knee and elbow joints, an uncontrollable jerking or flailing of the limbs and in many cases, a "weakening of the heart."1 What he was describing has come to be known as Rheumatic Fever. However, the association between strep throat infections and rheumatic fever had not been made until the late 1800’s. Then in 1944, T. Duckett Jones, MD published criteria by which the condition became defined. Rheumatic fever gets its name from its most common symptoms – rheumatism (inflammation of the
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

Environment, dietary and lifestyle factors play a big role in how rheumatic heart disease is spread. Most developing countries have a higher percentage of people how suffer from rheumatic heart disease because the poor state of the environment they inhabit. Dietary factors can play a role only due to insanitary condition in which food is made not due to the amount of food eaten due the fact that RHD is caused by a bacteria. Lifestyle factors contribute to rheumatic heart disease because most people

Primary infection is particularly usual in childhood and establishes a lifelong carrier state where the virus remains latent. The EBV replicates frequently in the oropharyngeal epithelial cells and circulating B-lymphocytes, since they are the principal targets of the virus.

It is not unusual for some healthy women to harbor Group B streptococcus bacteria in their rectum and vagina. These microorganisms do not usually cause disease when few in number, but when they grow in number and colonize these areas, bacterial infection can become severe. A woman who is pregnant and tests positive for Group B strep or GBS may pass the bacteria to her baby during childbirth. GBS affects one out of 2,000 newborns in the US although not all babies born to GBS-positive mothers become
school age kids are at higher risk for contracting this all too common viral infection. One of the main reasons, children visits their doctors or stay home from school is related to Rhinovirus, Influenza virus and Group B streptococcal infections (Johns Hopkins Medicine).
Overview Impetigo is a bacterial skin infection characterized by the eruptions of superficial pustules and formation of thick yellow crusty sores. It is highly contagious and can occur anywhere on the body, especially in exposed areas. The two different types of Impetigo are Bullous Impetigo, which are large blisters, and Non-Bullous Impetigo, which are crusted over blisters. Non-Bullous Impetigo is the most common type. Both types require contact precautions because they can be transmitted via
