Contraction and Spread of Streptococcus pyogenes

The scarlet fever is a bacterial illness. The fever is a result of strep throat; after a victim has strep throat it can then develop into scarlet fever. The illness lives in the nose and throat of humans. Since it is found in these areas, it can be easily spread through the air by a cough or sneeze. It can be spread from drinking or eating after someone who is infected. It can also be spread if one comes in contact with somewhere that an infected person coughed or sneezed, then touches their eyes, mouth, or nose. (Mayo Clinic)

Coughing and sneezing can spread the viruses easily. Infected stool may be infectious, such as changing a diaper or children use hands to touch their stool before touching another objects and put in their mouths..

Staphylococcus aureus is the leading cause of skin and soft tissue infections, it can cause serious infections such as bloodstream infection, pneumonia or bone infections. Though it can cause infections it is part of the normal human flora it is mostly found on the skin or in nasal cavities. It is a facultative anaerobic gram positive cocci, it is usually in pairs or clusters. The bacterium is also catalase positive, oxidase

| Usually caused by a virus, can be spread in much the same way as the common cold.Children can also become infected if they have contact with fluid from the blisters or saliva of someone who is infected.

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 of rheumatic fever and glomerulonephritis. Due to the severity of these medical consequences, prophylactic antibiotic use is often recommended for any patients with otherwise mild S. pyogenes infections (21).

Streptococcus Pyogenes is a very diverse bacteria with effects ranging from nothing or a mild sore throat, to flesh eating disease, causing death in 40-60% of patients. The major and most common illnesses associated with this bacteria

A Proteus infection may begin exogenously or endogenously. The mode of transmission for Proteus infections may be through direct or indirect contact. The pathogen is popular among hospitals; therefore, sources include hospital equipment, invasive procedures, hospital food and the hands of employees. It can be an endogenous infection when the normal intestinal flora is disrupted by antibiotics. This allows Proteus vulgaris to colonize and grow uncontrollably (NCBI, 1996).

Meningococci are spread through coughing, sneezing and intimate kissing - approximately 10% of the general population carry meningococcal bacteria harmlessly in the back of their throats at any one time. This natural carriage is, therefore, relatively common and helps develop immunity.

S.pyogenes is a species of bacteria that usually attack children 6-18 years old . S.pyogenes is also known as strep throat which is a really common infection.S.pyogenes is an infection in the throat and tonsils. No one can diagnose throat just by looking at your throat. Whenever you have the symptoms you should go the doctors so they can give a “rapid strep test” which involves swabbing your throat. If you test positive for strep throat the doctor will give you some antibiotics which will help you get well by decreasing the time you’re sick ,weakening the symptoms, stops its infectivity and it also prevents more serious complications such as tonsil and sinus infections and rheumatic fever.

Staphylococcus aureus is a gram positive cocci that forms grape like clusters, produces catalase, has a peptidoglycan and teichoic acid cell wall, and has a G + C content of DNA ranging from 30-40 mol%. An estimated 20% of the human population is long-term carriers of S. aureus, appearing in the nares of the nasal passages and also part of the natural skin flora which is the most common species of Staphylococcus to cause Staph infections. S. aureus is a successful pathogen due to a combination of nasal carriage and bacterial immuno-evasive strategies. S. aureus can cause minor skin infections, pimples, impetigo, boils or furuncles, cellulitis, folliculitis, carbuncles, scalded skin syndrome, and abscesses. Life-threatening diseases such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome, bacteremia, and sepsis are also caused by pathenogenic S. aureus. Its extent ranges from skin, soft tissue, respiratory, bone, joint, and endovascular to wound infections. Nosocomial infections and often postsurgical wound infections are a commonly caused by S. aureus. S. aureus is also a prominent cause of food poisoning in the US, and can be transmitted by different foods, including milk and

Strep throat is an infection of the throat. It is caused by a germ. Strep throat spreads from person to person by coughing, sneezing, or close contact.

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. From this site it can aspire to the lungs, eventually spread to the blood and traverse the blood-brain barrier to the meninges, once inside the blood it can cause infections throughout the body. Symptoms of the disease include sudden

SARS appears to spread by close person-to-person contact. It is thought that transmission is most readily occurred through respiratory droplets. These can be produced when an infected person coughs or sneezes. These droplets are propelled through the air and are deposited on the mucous membranes of the mouth, nose, or eyes of a person that is nearby. It is also possible that the virus can spread when a person touches a surface or object contaminated with infectious droplets and then touches their mouth, nose, or eyes. Furthermore, it is possible that SARS-CoV might be airborne spread or by other methods that are not yet known.

It is an infection caused by pathogens such as viruses, but more likely bacteria, especially when children are getting sick. In particular, the "responsible" is the number one affection Streptococcus, to be defeated, as we shall see in a moment, with the right

still be contagious until all the symptoms are over. It can spread through saliva, coughing,
