However, I couldn't find any specific information on an "obsolete commensal Actinomycetales infectious disease". It's possible that this is a rare or outdated term.

If you

Based on the provided context, it appears that you are looking for information on the signs and symptoms of an outdated commensal Actinomycetales infectious disease.

According to search result [5], Actinomycosis is a rare indolent infectious disease characterized by abscess formation, invasiveness mimicking malignancy. However, I couldn't find any specific information on obsolete commensal Actinomycetales infectious disease in the provided context.

But, I can provide you with some general information on Actinomycosis, which might be relevant to your query:

• Symptoms of Actinomycosis include:
  • Painful, indurated cutaneous and soft tissue swelling ("woody" fibrosis) [1]
  • Odontogenic abscess ("lumpy jaw syndrome") [1]
  • Draining sinus tracts with "sulfur granules" [4]
• Other symptoms mentioned in the context include:
  • Fever, cough, hemoptysis, chest wall pain, weight loss, sputum production, draining sinuses from the chest wall, dissemination to pleura, pericardium [2]

Please note that these symptoms are associated with Actinomycosis, which is a rare infectious disease. The context does not provide specific information on obsolete commensal Actinomycetales infectious disease.

If you could provide more context or clarify your query, I'll be happy to try and assist you further.

Based on the provided context, it appears that you are looking for information on diagnostic tests related to an infectious disease caused by Actinomycetales.

According to search result [13], Charlotte Radiology offers imaging services such as MRI scans, CT scans, X-rays, ultrasounds & screening mammograms. However, there is no specific mention of diagnostic tests for Actinomycetales infections.

Search result [14] mentions an Associate of Science Degree program in Diagnostic Medical Sonography, but it does not provide information on diagnostic tests for infectious diseases caused by Actinomycetales.

Search result [15] talks about Interventional Radiologists treating various conditions, including cancer. However, there is no specific mention of diagnostic tests for Actinomycetales infections.

It's worth noting that Actinomycetales are a group of bacteria that can cause various diseases in humans, including actinomycosis. The diagnosis of actinomycosis typically involves a combination of clinical evaluation, laboratory tests (such as blood cultures and imaging studies), and histopathological examination of tissue samples.

If you're looking for information on diagnostic tests for Actinomycetales infections, I would recommend searching for more specific and relevant results. However, based on the provided context, it seems that there is limited information available on this topic.

Here are some possible diagnostic tests that may be used to diagnose Actinomycetales infections:

• Blood cultures: To detect the presence of Actinomyces bacteria in the blood.
• Imaging studies (such as X-rays, CT scans, or MRI): To visualize any abscesses or other lesions caused by the infection.
• Histopathological examination: To examine tissue samples for the presence of Actinomyces bacteria and to rule out other conditions.
• PCR (Polymerase Chain Reaction) tests: To detect the genetic material of Actinomyces bacteria in clinical specimens.

Please note that these are general possibilities, and the specific diagnostic tests used may vary depending on the individual case and the expertise of the healthcare provider.

The treatment of obsolete commensal Actinomycetales infections has evolved over time, and the current drug options may not be as effective as they once were.

According to search result [7], Amphotericin B is one of the best-known polyene macrolides produced by Streptomyces nodosus. However, its effectiveness against Actinomycetales infections is unclear.

In the past, antibiotics such as penicillin and rifamycin (search result [9]) were used to treat various bacterial infections, including those caused by commensal bacteria like Actinomycetales. However, the rise of antibiotic resistance has made these treatments less effective.

A study published in search result [8] identified an expanded pool of tet(X)-like genes in environmental and human commensal metagenomes via inactivation by antibiotic selection. This suggests that the genetic makeup of Actinomycetales bacteria may have changed over time, making them more resistant to traditional antibiotics.

More recent research (search results [4], [6]) has focused on the development of new antimicrobial therapies, such as polymyxin E (colistin) and lefamulin. These drugs show promise in treating drug-resistant microorganisms, including Actinomycetales infections.

However, it's essential to note that the treatment landscape for obsolete commensal Actinomycetales infections is complex and may require a multidisciplinary approach. Further research is needed to develop effective treatments for these types of infections.

The differential diagnosis for an obsolete commensal Actinomycetales infectious disease, such as actinomycosis, can be quite challenging due to its rare and heterogeneous nature. However, based on the search results, here are some possible differential diagnoses:

• Anal fistula with common bacteria: This is a plausible differential diagnosis for actinomycosis, especially in cases where the infection presents with anal or perianal symptoms (Context 3).
• Tuberculosis: Actinomycosis can be mistaken for tuberculosis due to its chronic and granulomatous nature. In fact, one of the search results mentions that differential diagnoses include "tuberculosis, Crohn disease, and exceptionally cancer" (Context 3).
• Crohn disease: Similar to anal fistula, Crohn disease is another possible differential diagnosis for actinomycosis, particularly in cases where the infection presents with gastrointestinal symptoms.
• Cancer: In rare cases, actinomycosis can be mistaken for cancer due to its chronic and destructive nature. However, this is an exceptional differential diagnosis (Context 3).
• Botryomycosis: This is a term used to describe a variety of infections by colonies of Gram-positive cocci, which can grossly appear comparable to the sulfur granules caused by Actinomyces (Context 12).
