Obsolete Rhabditida Infectious Disease

The obsolete Rhabditida infectious disease, also known as a Chromadorea infectious disease, is an outdated term that refers to a type of parasitic infection caused by nematodes (roundworms) of the order Rhabditida.

• Characteristics: This infectious disease involves infection by parasitic nematodes with oral apertures having 2, 3 or 6 lips. [1][2][3]
• Hosts: The disease affects various hosts, including ruminants, horses, cats, dogs, swine, and humans. [5][6]
• Gastrointestinal tract involvement: The infection involves parasitic infection of the gastrointestinal tracts of these hosts. [5][6]

It's worth noting that the term "obsolete Rhabditida infectious disease" is no longer used in modern medical literature, as it has been replaced by more specific and accurate terms such as Strongylida infectious disease or Rhabditida infections. [4][11]

Based on the provided context, it appears that there are limited resources available for information on obsolete Rhabditida infectious diseases.

However, I was able to find some relevant information in search results [4] and [8].

According to these sources, signs and symptoms of Rhabditida infectious disease include:

• Eosinophilia (an increase in eosinophils, a type of white blood cell)
• Hepatomegaly (enlargement of the liver)
• Splenomegaly (enlargement of the spleen)
• Lung infections

It's worth noting that Rhabditida infectious diseases are considered obsolete, and therefore, there may be limited information available on this topic.

Obsolete Diagnostic Tests for Rhabditida Infectious Disease

The diagnostic tests for Rhabditida infectious disease, also known as Strongyloidiasis, have evolved over the years. While some methods are still used today, others have been rendered obsolete due to advancements in medical technology and a better understanding of the disease.

Discontinued Diagnostic Tests:

• Direct Smear Examination: This method, which involves examining stool samples under a microscope for larvae, has largely been replaced by more sensitive and specific tests (2).
• Baermann's Technique: Although still used in some cases, this method has been superseded by more efficient concentration techniques such as formalin-ethyl acetate concentration (3).

Historical Context:

In the past, diagnosis of Rhabditida infectious disease relied heavily on clinical presentation and indirect methods. The use of serology for diagnosis was also explored, but its reliability and sensitivity were limited (5). However, with the advent of molecular-based approaches and PCR-based platforms, diagnostic testing has become more accurate and efficient.

Current Diagnostic Methods:

Today, diagnosis of Rhabditida infectious disease is primarily based on:

• PCR-based Platforms: These have revolutionized diagnostic testing for parasitic diseases, including Strongyloidiasis (13).
• Immunological Assays: These are used to detect specific antibodies or antigens in the body, providing a more accurate diagnosis (11).

Conclusion:

While some diagnostic tests for Rhabditida infectious disease have been rendered obsolete, others continue to play a role in diagnosis. The evolution of medical technology and our understanding of the disease have led to more accurate and efficient diagnostic methods.

Differential Diagnoses for Obsolete Rhabditida Infectious Diseases

Rhabditida, a group of nematodes, includes some genera with parasitic phases that can cause infections in humans. While many of these diseases are considered obsolete or rare, it's essential to consider their differential diagnoses when encountering similar symptoms.

• Ascariasis: Caused by the Ascaris lumbricoides parasite, ascariasis is a common intestinal infection characterized by diarrhea, abdominal pain, and weight loss.
  • [10] Rhabditida comprises all of the free-living forms, one of the largest groups of nematodes. Some genera have a parasitic phase, while others are only facultative parasites. One important member of Rhabditida is Strongyloides, with at least seven species known in humans, producing intestinal and dermal infections.
• Trichuriasis: Trichuriasis is caused by the whipworm (Trichuris trichiura) parasite and can lead to symptoms like diarrhea,
