Infectious diseases biological samples and experimental services

What are infectious diseases?

Infectious diseases can range from mild to severe and can affect different parts of the body. The symptoms of an infectious disease depend on the type of pathogen and the severity of the infection. Common symptoms include fever, fatigue, cough, headache, muscle aches, and rash. Some infectious diseases can be treated with antibiotics, antivirals, or other medications, while others may require supportive care to manage symptoms until the body's immune system can clear the infection.

Some infectious diseases can be prevented through vaccination, good hygiene practices, and avoiding close contact with infected individuals. Early detection and treatment of infectious diseases is important to prevent the spread of the disease to others and to prevent serious complications from developing.

What types of samples are used in infectious disease research?

In infectious disorder research, various types of samples can be collected and analyzed to understand the underlying causes and mechanisms of the disease, as well as to develop and evaluate diagnostic and therapeutic methods. Some of the most common types of samples used in infectious disease research include:

Stool samples

Used to assess the presence of bacteria, viruses, or parasites, as well as to measure biomarkers that indicate gastrointestinal inflammation.

Biopsy samples

Obtained through endoscopy or laparoscopy procedures, used to examine the tissue and cells of the gastrointestinal tract for signs of inflammation or other changes.

Blood samples

Used to measure levels of certain hormones, cytokines, or other markers that indicate the presence of a gastrointestinal disorder.

Mucosal samples

Obtained by wiping the inside of the gut with a swab, used to assess the microflora and immune function in the gut.

Urine samples

Used to measure levels of specific metabolic byproducts that may indicate the presence of a gastrointestinal disorder.

These samples can provide valuable information to help diagnose, monitor, and treat gastrointestinal disorders.

What is the role of biobanks?

Biobanks (also known as biological resource centers) are entities responsible for the management of biological samples and their associated data. These structures can collect and preserve infectious materials in the form of samples inventory.

Infectious substances (or infectious materials) are biological specimens that are suspected or known to contain pathogens such as bacteria, viruses, fungi, prions or parasites that cause infectious or parasitic diseases in humans and animals.

These samples may be in the form of strains (viral, bacterial, fungal) or biological samples from infected patients or animals by viruses like the coronavirus SARS-CoV-2 or HIV, such as tissue, tissue fluid or blood samples.

Setting up a collection of biological samples

After a biopsy, or other procedure to retrieve a human sample, a sample may be retained, with the patient's consent, for research purposes.

Storage of clinical samples

The samples, after collection, must be stored under certain conditions, depending on their type and shelf life, to allow for their viability.
