Two examples of past show topics for the first hour include " European & Arab Media on the U. S. in Iraq " and " Drug-Resistant Bacteria ".

Less common organisms include: Haemophillus influenzae, Streptococcus pneumoniae and Neisseria meningitides.

Griffith used two strains of pneumococcus ( Streptococcus pneumoniae ) bacteria which infect mice – a type III-S ( smooth ) and type II-R ( rough ) strain.

Before that, in two separate experiments, Frederick Griffith and Oswald Avery, Colin MacLeod, and Maclyn McCarty had shown that DNA led to the transformation of one strain of Streptococcus pneumoniae to another that was more virulent.

Antibiotic macrolides are used to treat infections caused by Gram-positive bacteria ( e. g. Streptococcus pneumoniae ) and Haemophilus influenzae infections such as respiratory tract and soft-tissue infections.

If the infection is of bacterial origin, the most common three causative agents are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.

In the medical setting, the most important groups are the alpha-hemolytic streptococci S. pneumoniae and Streptococcus Viridans-group, and the beta-hemolytic streptococci of Lancefield groups A and B ( also known as “ Group A strep ” and “ Group B strep ”).

Notable examples of this mode of resistance include methicillin-resistant Staphylococcus aureus ( MRSA ) and penicillin-resistant Streptococcus pneumoniae.

There are many other types of Streptococcus including Group B Streptococcus and Streptococcus pneumoniae which cause other types of infections and should not be confused with Group A Strep.

(* Note that menigitis, sinusitis and pneumonia can all be caused by Group A Strep, but are much more commonly associated with Streptococcus pneumoniae and should not be confused.

Meningitis is most commonly caused by infections with various pathogens, examples of which are Streptococcus pneumoniae and Haemophilus influenzae.

* WFS can also be caused by Streptococcus pneumoniae infections, a common bacterial pathogen typically associated with meningitis in the adult and elderly population.

He showed that Streptococcus pneumoniae, implicated in many cases of lobar pneumonia, could transform from one strain into a different strain.

The most common bacterial pathogen is Streptococcus pneumoniae.

* Infections: Gram-negative sepsis, Neisseria meningitidis, Streptococcus pneumoniae, malaria, histoplasmosis, aspergillosis, Rocky mountain spotted fever

* Infection: due to leakage of immunoglobulins, encapsulated bacteria such as Haemophilus influenzae and Streptococcus pneumoniae can cause infection.

The most common bacteria implicated are Staphylococcus aureus, Streptococcus pneumoniae, Hemophilus influenzae, and Moraxella catarrhalis.

Furthermore, when incubated in vitro with either mitogens or specific antigens, they produce specific antibodies against diphtheria toxoid, poliovirus, Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, and the lipopolysaccharide of E. coli.

* 1977 First vaccine for pneumonia ( Streptococcus pneumoniae )

and was contrasted with the bacterial pneumonia caused by Streptococcus pneumoniae, at that time the best known and most commonly occurring form of pneumonia.

He died on May 16, 1990, of organ failure resulting from a Group A streptococcal infection caused by Streptococcus pyogenes.

Azithromycin has been used to treat strep throat ( Group A streptococcal ( GAS ) infection caused by Streptococcus pyogenes ) in penicillin-sensitive patients, however macrolide-resistant strains of GAS are not uncommon.

S. pyogenes, also known as Group A Streptococcus ( GAS ), is the causative agent in Group A streptococcal infections, including streptococcal pharyngitis (" strep throat "), acute rheumatic fever, scarlet fever, acute glomerulonephritis and necrotizing fasciitis.

Other Streptococcus species may also possess the Group A antigen, but human infections by non-S. pyogenes GAS strains ( some S. dysgalactiae subsp.

Group A Streptococcus infection is generally diagnosed with a Rapid Strep Test or by culture.

In the UK, only 1 % of maternity units test for the presence of Group B Streptococcus.

Streptococcus dysgalactiae is also a member of Group C, β-haemolytic streptococci that can cause pharyngitis and other pyogenic infections similar to Group A streptococci.

The remaining nonenterococcal Group D strains include Streptococcus bovis and Streptococcus equinus.

* Group B Streptococcus screen – will receive IV penicillin or ampicillin ( it is much cheaper and has a wider coverage ) if positive ( if mother is allergic, alternative therapies include IV clindamycin or IV vancomycin )

The Group A β-hemolytic streptococcus ( Streptococcus pyogenes, or GAS ) is a form of β-hemolytic Streptococcus bacteria responsible for many common infections including " strep throat " and skin infections.

Pathogenic bacteria contribute to other globally important diseases, such as pneumonia, which can be caused by bacteria such as Streptococcus and Pseudomonas, and foodborne illnesses, which can be caused by bacteria such as Shigella, Campylobacter and Salmonella.

Most cases of erysipelas are due to Streptococcus pyogenes ( also known as beta-hemolytic group A streptococci ), although non-group A streptococci can also be the causative agent.

In vivo hemolysis can be caused by a large number of medical conditions, including many Gram-positive bacteria ( e. g., Streptococcus, Enterococcus, and Staphylococcus ), some parasites ( e. g., Plasmodium ), some autoimmune disorders ( e. g., Hemolytic disease of the newborn ), and some genetic disorders ( e. g., Sickle-cell disease or G6PD deficiency ).

Visualizing the physical appearance of hemolysis in cultured blood samples may be used as a tool to determine the species of various Gram-positive bacteria infections ( e. g., Streptococcus ).

A person may be a carrier of a disease, such as Streptococcus in the throat, without exhibiting any symptoms.

It is widely claimed that a common type of bacteria, Streptococcus mitis, accidentally contaminated the Surveyor's camera prior to launch, and that bacteria survived dormant in the harsh lunar environment for two and one-half years, supposedly then to be detected when Apollo 12 brought the Surveyor's camera back to the Earth.

Staphylococcus should not be confused with the similarly named and medically relevant genus Streptococcus.

Members of the genus Enterococcus were classified as Group D Streptococcus until 1984, when genomic DNA analysis indicated a separate genus classification would be appropriate.

The primary bacteria used are typically Lactobacillus bulgaricus and Streptococcus thermophilus, and US law requires all yogurts to contain these two cultures ( though others may be added as probiotic cultures ).

An example of this would be Streptococcus viridans.

In general, occult pneumonia is rather often present in patients with pneumonia and can also be caused by Streptococcus pneumoniae, as the decrease of occult pneumonia after vaccination of children with a pneumococcal vaccine suggests.

Patients with positive cultures for Streptococcus pyogenes should be treated with penicillin as long as allergy is not present.

They can be used in single-strain starter cultures, or in mixed-strain cultures with other lactic acid bacteria such as Lactobacillus and Streptococcus.

For example, a throat culture is taken by scraping the lining of tissue in the back of the throat and blotting the sample into a medium to be able to screen for harmful microorganisms, such as Streptococcus pyogenes, the causative agent of strep throat.

Viridans group streptococci and Streptococcus bovis are usually highly susceptible to penicillin and can be treated with penicillin or ceftriaxone.

Selected patients may be treated with a relatively shorter course of treatment ( 2 weeks ) with benzyl penicillin IV if infection is caused by viridans goup streptococci or Streptococcus bovis as long as the following conditions are met:
