Streptococcus

normal flora are opportunistic, and they need a way of entry in order to be harmful to the individual. Neisseria, Staphylococcus aureus, and Streptococcus are examples of bacteria that if given the opportunity can be harmful to humans. Growing the bacteria, gram staining and performing an oxidase test can be done

Truman Nord Biol 231L Sec.3 November 11, 2014 Identifying Unknown Bacteria: Streptococcus agalactiae Introduction: This experiment was conducted to find the genus and species of an unknown bacteria prescribed by the lab teacher, which was unknown bacteria GA3 in my case. Identification of unknown bacteria techniques are used on an every day basis to figure out what type of bacteria it is and to find the best method of how to treat a patient with this bacteria (1). All five “I’s” of Microbiology

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

S. pneumoniae is capnophilic, preferring atmospheres of 5–10% carbon dioxide. Streptococcus pneumoniae can be distinguished from other streptococci, owing to the fact that it is catalase negative; can be inhibited by ethyl hydrocupreine; it is soluble in bile (due to activation of autolytic property, which consequently lead to cell lysis);

Effects and Diseases of the Bacterium Streptococcus Pyogenes The bacteria Streptococcus pyogenes has been infecting people for more than a century. Once a deadly bacterium, now only an antibiotic from curing the diseases it causes. Streptococcus pyogenes has been responsible for excruciating throat pains and even in some cases a horrendous rash included. This paper will talk about the history of this organism, how it acts as a pathogen, how people attract it, the symptoms that come with the disease

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

Section:307 ABSTRACT Streptococcus pneumoniae was discovered by Louis Pasteur in pneumonia patients in 1881. It is a gram positive coccus that forms short chains or more commonly, pairs and classified in its own genus, called “Diplococcus”. Streptococcus pneumonie is a pneumococcal pneumonia consists about 85 % of all cases of pneumonia. Around ninety two different strains of S. Pneumoniae, collectively called pneumococci, are known to cause harm on humans. Streptococcus pneumonia is a member of

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 Pyogenes is a Gram-positive, nonmotile, nonsporeforming coccus that occurs in chains or in pairs of cells.” (Todar's Online Book of Bacteriology) In history, Streptococcus pyogenes got its ill repute as the cause of puerperal fever, a life-threatening disease that was seen in women after childbirth, until Ignaz Semmelweis exposed that it could be stopped by physicians just washing their hands before each vaginal examination.( Live Strong) S. pyogenes is one of the most frequent pathogens

Staphylococcus, Enterococcus and Streptococcus is considered as a leading cause of many diseases. They are considered different due to their morphology. The Staphylococci and Streptococci acquires a round, spherical cell shape. On the other hand, the arrangement of cells is considered different for both the organisms. For instance, Staphylococcus aureus is a gram-positive, cluster-forming cocci and a nonsporeforming facultative anaerobe which is found in grape like structures. Enterococcus is also
