How Do You Spell BACTERIAL CAPSULE?

Pronunciation: [baktˈi͡əɹɪə͡l kˈapsjuːl] (IPA)

The spelling of the word "Bacterial Capsule" starts with the phoneme /b/ represented by the letter 'B', followed by the phoneme /æk/ represented by the letters 'ac', and ends with the phoneme /sjuːl/ represented by the letters 'sule'. The phonetic transcription for "Bacterial Capsule" is /bækˈtɪəriəl ˈkæpsjuːl/, where each symbol corresponds to a single sound in the word. The bacterial capsule is a protective layer surrounding bacteria that aids in their survival and evasion of the immune system.

BACTERIAL CAPSULE Meaning and Definition

1. A bacterial capsule is a gelatinous layer that surrounds the cell wall of certain bacteria. It is a protective structure, usually composed of a complex arrangement of polysaccharides or glycoproteins, that plays a crucial role in the survival and pathogenicity of the bacterium.

   The bacterial capsule acts as a physical barrier, preventing the desiccation (drying out) of the bacterium and protecting it from host immune responses. It also helps to shield the bacterium from environmental stresses such as osmotic pressure, temperature variations, and chemical disinfectants. The capsule can also reduce the effectiveness of phagocytosis, the process by which immune cells engulf and destroy bacteria.

   The composition of a bacterial capsule can vary greatly between different species or strains of bacteria, which contributes to their distinctiveness and ability to cause diseases. Some capsules, known as slime layers, are loosely attached to the cell surface, while others, called true capsules, are highly organized and firmly attached.

   Clinically, the presence of a bacterial capsule is considered a major virulence factor in pathogenic bacteria, as it enhances their ability to establish infections and evade host defense mechanisms. This makes capsules important targets for vaccines and antimicrobial drugs.

   In summary, the bacterial capsule is a protective layer surrounding certain bacteria, composed mainly of polysaccharides or glycoproteins. It provides essential defense mechanisms against the host immune system and environmental challenges, contributing to the bacteria's pathogenicity and overall survival.

Etymology of BACTERIAL CAPSULE

The term "bacterial capsule" comes from combining two separate concepts: "bacterial" and "capsule".

1. Bacterial: The word "bacterial" refers to anything related to bacteria. It is derived from the Greek word "baktēria", which originally designated a rod-like shape, resembling the shape of many bacteria. Over time, the term "bacteria" started to refer specifically to microorganisms that have distinct cellular structures and can cause various diseases.

2. Capsule: The word "capsule" comes from the Latin word "capsula", meaning a small container or case. In the context of biology, a capsule refers to a protective structure surrounding certain microorganisms that can be composed of various substances, including polysaccharides. The term capsule also refers to similar protective structures found in plants and other organisms.
