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

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

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

most 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

Contraction and Spread of Streptococcus pyogenes Abstract: 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

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 is a microorganism from the kingdom of bacteria that is considered to be a unique and extremely complex opportunistic pathogen. The bacterium is especially unique because it has the ability to cause several diseases, ranging from mild to severe outcomes. Streptococcus pyogenes is named so because strepto means chains, coccus is used to describe a spherical shape, and pyogenes is used to describe a pus-forming organism. “S. pyogenes is considered one of the most frequent pathogens

Resistance, Infections, and Defenses of Streptococcus pyogenes Streptococcus pyogenes was the bacteria that used to be the cause of numerous cases of human sicknesses and deaths. As our technology evolved and advanced, our perspective and understanding of this bacteria grew to a point that it is no longer a huge threat. The once blurry details became so clear that it came to the point of which we can identify, locate, and treat the bug accurately. After those many years of dedication and research

Streptococcus Pyogenes: Multi-Purpose Monsters Streptococcus pyogenes is a type of group A streptococci that causes many infectious diseases. This bacteria is commonly found in a variety of organisms, but is usually harmless unless the organisms defenses are compromised. When detrimental, group A streptococci cause infections such as impetigo, ecthyma, scarlet fever, and necrotizing fasciitis. Each of these infections displays different symptoms and requires different treatment. These treatments
