obsolete commensal streptococcal infectious disease
Description
Based on the provided context, it appears that there are multiple types of streptococcal infections mentioned, but one specific type is described as an "obsolete" commensal streptococcal infectious disease.
According to search result [10], this obsolete disease is caused by Group A Streptococcus bacteria and involves infection of the pharynx and sometimes the larynx and tonsils. The common symptoms include fever, sore throat, headache, stomach ache, nausea, or chills.
Additionally, search result [11] mentions that this disease is also known as streptococcal infection, streptococcosis, streptococcal infectious disease, Streptococcal infection, unspecified (disorder), and commensal streptococcal infectious disease.
It's worth noting that this disease is described as obsolete, which means it is no longer considered a significant or relevant medical condition in modern times.
Additional Characteristics
- chills
- fever
- headache
- nausea
- sore throat
- Group A Streptococcus bacteria
- pharynx infection
- larynx and tonsils infection
- stomach ache
Signs and Symptoms
Based on the provided context, it appears that you are referring to an "obsolete" commensal streptococcal infectious disease, which is no longer considered a valid medical condition. However, I will provide information on the signs and symptoms of a similar condition, as described in search result 10.
Common Symptoms:
- Fever
- Sore throat
- Headache
- Stomach ache
- Nausea or chills
These symptoms are associated with an "obsolete" commensal streptococcal infectious disease that involves infection of the pharynx and sometimes the larynx and tonsils. It is caused by Group A Streptococcus bacteria.
Other Possible Symptoms:
- Difficulty swallowing or pain when swallowing
- Small red spots on the roof of your mouth
- Swollen tonsils or lymph nodes
Please note that this information is based on an outdated medical condition, and it's essential to consult a healthcare professional for accurate diagnosis and treatment.
Diagnostic Tests
Diagnostic Tests for Obsolete Commensal Streptococcal Infectious Diseases
The diagnostic tests for obsolete commensal streptococcal infectious diseases, such as Group C and G streptococci, have been largely replaced by more modern and effective methods. However, some of these older tests are still relevant in certain contexts.
- CAMP Test: The CAMP test is a simple test used to detect the presence of group B streptococci (GBS). It involves mixing a sample of blood or other bodily fluid with an antibiotic, which causes the GBS bacteria to grow and produce a characteristic pattern. [1]
- Rapid Streptococcus Antigen Test (RSAT): The RSAT is a rapid diagnostic test used to detect the presence of streptococcal antigens in body fluids. It is commonly used to diagnose Group A streptococcal infections, but can also be used for other types of streptococcal infections. [2]
- Immunoassay: Immunoassays are a type of diagnostic test that use antibodies to detect the presence of specific antigens in body fluids. They have been used to diagnose various streptococcal infections, including Group A and B streptococci. [10]
Relevance of Older Diagnostic Tests
While these older diagnostic tests may not be as widely used today, they can still be relevant in certain contexts.
- Historical significance: Understanding the history of diagnostic testing for streptococcal infections is important for appreciating the development of modern diagnostic methods.
- Rarity of obsolete commensal streptococci: In areas where Group C and G streptococci are still prevalent, older diagnostic tests may be more relevant due to their specificity for these types of bacteria.
Modern Diagnostic Approaches
In contrast to older diagnostic tests, modern approaches have become the standard for diagnosing streptococcal infections.
- Molecular diagnostics: Molecular diagnostic techniques, such as PCR (polymerase chain reaction), are highly sensitive and specific for detecting streptococcal DNA in body fluids.
- Antigen detection: Antigen detection tests, like the RSAT, have become more widely used due to their ease of use and rapid results.
Conclusion
While older diagnostic tests for obsolete commensal streptococcal infectious diseases are still relevant in certain contexts, modern approaches have become the standard for diagnosing these infections. Understanding the history and relevance of older diagnostic tests is important for appreciating the development of modern diagnostic methods.

Treatment
Treatment Options for Obsolete Commensal Streptococcal Infectious Disease
Obsolete commensal streptococcal infections refer to diseases caused by Group A beta-hemolytic streptococci (GABHS) that are no longer commonly seen in modern medicine. However, these infections can still occur and require proper treatment.
Antibiotic Treatment
The primary treatment for obsolete commensal streptococcal infectious disease is antibiotics. According to various medical sources [3][8], penicillin is the drug of choice for treating GABHS infections, including those caused by Group A streptococcus bacteria [7]. Penicillin alternatives such as amoxicillin and benzathine can also be used in cases where patients have an allergy to penicillin [9].
Specific Treatment Options
- Penicillin V: 500 mg orally two to three times daily for 10 days is a commonly prescribed treatment option [4].
- Oral cephalosporins: Short-course regimens of oral cephalosporin therapy have been shown to be effective in treating streptococcal pharyngitis [5].
- Amoxicillin suspension: This medication is often substituted for penicillin due to its better taste and is available as chewable tablets [6].
Prevention
While antibiotics can effectively treat obsolete commensal streptococcal infectious disease, prevention is key. Washing hands frequently, especially before eating or after being in contact with an infected person, can help prevent the spread of infection [12]. Avoiding sharing utensils, linen, or personal items can also reduce the risk of transmission.
Complications
Untreated GABHS infections can lead to serious complications, including rheumatic fever and acute glomerulonephritis. These conditions can cause life-long cardiac problems if not treated promptly or properly [13].
Differential Diagnosis
Differential Diagnosis of Obsolete Commensal Streptococcal Infectious Disease
The differential diagnosis of obsolete commensal streptococcal infectious diseases involves identifying and ruling out other possible causes of infection. This is particularly relevant for streptococcal infections that were once considered common but have since become rare or obsolete.
Possible Causes:
- Neisseria Infections: Commensal Neisseria infections are rare but can present serious invasive diseases [9].
- Other Bacterial Infections: Other bacterial infections, such as those caused by Staphylococcus aureus or Escherichia coli, may also be considered in the differential diagnosis.
- Viral Infections: Viral infections, such as influenza or respiratory syncytial virus (RSV), can also present with similar symptoms to streptococcal infections.
Key Considerations:
- Clinical Presentation: The clinical presentation of the infection is crucial in making a differential diagnosis. Symptoms such as fever, rash, and joint pain may be indicative of a streptococcal infection.
- Laboratory Tests: Laboratory tests, such as blood cultures or PCR, can help to confirm the presence of a streptococcal infection.
- Imaging Studies: Imaging studies, such as X-rays or CT scans, may also be necessary to rule out other possible causes of infection.

- [9] Commensal Neisseria infections are rare but can present serious invasive diseases.
- [11] The diagnosis of poststreptococcal diseases, such as rheumatic fever or glomerulonephritis, can be aided by the detection of specific streptococcal antibodies.
