Acinetobacter

Acinetobacter is a genus of Gram-negative bacteria. Acinetobacter baumannii, in particular, can cause healthcare-associated infections and may be difficult to treat due to antibiotic resistance.

Actinomycetes

Actinomycetes are gram-positive bacteria, which are commonly found in nature. They produce interesting natural products, which are the basis of many of the antibiotics developed so far.

Adaptive immune response

The adaptive immune response is the part of the immune defense that specifically targets certain antigens. It is mediated primarily by B and T cells and can develop immunological memory.

Adoptive immunotherapy

Adoptive immunotherapy is a new approach, partly still under development, to treat cancer and viral infections.

AIDS

AIDS (Acquired Immune Deficiency Syndrome) is a weakness of the immune system caused by infection with the human immunodeficiency virus (HIV).

Amidochelocardin

Amidochelocardin is a broad-spectrum antibiotic.

Animal model

An animal model is a non-human animal species used in biomedical research because it can mimic aspects of a biological process or disease that occur in humans.

Anopheles mosquito

The Anopheles mosquito is a biting midge, which can transmit malaria.

Antibiotic resistance

Antibiotic resistance refers to the ability of bacteria to withstand one or more antibiotics, making these drugs less effective or ineffective.

Antibiotic Stewardship

Antibiotic Stewardship encompasses measures aiming at a more rational way of prescribing antibiotics.
