Enzyme-Linked Immunosorbent Assay01:33

Enzyme-Linked Immunosorbent Assay

In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen.  Enzyme-substrate reaction allows the antigen to be visualized or quantified.
Endocarditis IV: Nursing Management01:29

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
Rabies01:28

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Endocarditis I: Introduction01:25

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Summary
This summary is machine-generated.

Equine Infectious Anemia (EIA) is a viral disease affecting horses worldwide, transmitted by insects. Diagnosis relies on serological tests, and while Switzerland is EIA-free, it faces ongoing introduction risks.

Area of Science:

  • Veterinary Virology
  • Epizootiology
  • Equine Health

Context:

  • Equine Infectious Anemia (EIA) is a significant global epizootic disease impacting equids.
  • Caused by the equine lentivirus, a retrovirus, EIA is transmitted primarily through blood, often via insect vectors.
  • Clinical signs range from pyrexia and anemia to inapparent carrier states.

Purpose:

  • To provide a comprehensive overview of Equine Infectious Anemia.
  • To highlight diagnostic methods, including serological tests like Coggins and ELISA.
  • To emphasize the global distribution and transmission routes of the virus.

Summary:

  • EIA is a reportable and eradicable disease affecting only equids worldwide.
  • Transmission occurs mainly through blood-feeding insects.
  • Symptoms include fever, anemia, and edema, but asymptomatic carriers are common.
  • Diagnosis involves serological testing; Switzerland remains at risk despite being officially EIA-free.

Impact:

  • Understanding EIA is crucial for disease control and prevention strategies in equine populations.
  • Accurate diagnosis and monitoring are essential for maintaining EIA-free status in countries like Switzerland.
  • Awareness of EIA risks is vital due to recent outbreaks in neighboring European countries.
