  • Acid fast staining

    Acid fast staining is a staining technique used to identify microorganisms containing mycolic acid in their cell wall. The presence of mycolic acid prevents the removal of primary stain with acid alcohol, thus imparting acid-fastness to the organisms. Acid fastness is generally exhibited by bacteria such as Mycobacteria, their spores, and oocytes of protozoa. Ziehl-Neelsen technique is the most common acid fast staining procedure used, where in carbol fuchsin is applied as the primary stain, 20% sulphuric acid as the decoloriser and malachite green or Loeffler's methylene blue as the counterstain.

  • Actinomycetes

    Actinomycetes are a group of rod-shaped or filamentous bacteria that are mainly found in soil. They grow as branching filaments that resemble the hyphae of fungi. Some of the species of actinomycetes are pathogenic, while a majority of them produce antibiotics, such as streptomycin.

  • Active immunity

    Active immunity refers to the resistance developed by the production of antibodies in the body when exposed to harmful substances such as disease causing bacteria or virus. Active immunity can be naturally acquired when a person is directly exposed to microorganisms during infections, or it is artificially acquired by exposure to the antigenic components present in vaccines.

  • Aflatoxin

    Aflatoxin refers to any group of toxic chemicals produced by the fungi belonging to the genus Aspergillus, particularly Aspergillus flavus and Aspergillus parasiticus that grow on stored food supplies such as peanuts, wheat, corn, and rice. Aflatoxin leads to liver diseases, particularly liver cancer, in humans.

  • AIDS

    Acquired Immunodeficiency Syndrome (AIDS) is a severe immunological condition caused by the human immunodeficiency virus (HIV). AIDS increases susceptibility to opportunistic infections and cancers due to the defect in cell-mediated immune response.

  • Algae

    Algae are a group of chlorophyll-containing organisms that are mainly aquatic and range from microscopic single-celled forms to multicellular forms visible to the naked eye. Once considered as plants, algae lack the true roots, stems, and leaves that are characteristic of plants.

  • Anabolism

    Anabolism is the constructive metabolic process of synthesising complex molecules of the living cells such as fats and proteins, from simpler molecules when energy is required to build or repair cells.
