QUELLUNG Meaning and Definition

1. Quellung, also known as the Quellung reaction, is a laboratory technique used to identify specific bacteria based on their unique capsule characteristics. The term "quellung" is derived from the German word "quellen," which means to swell or enlarge. This reaction involves the use of specific antisera, which are antibodies created to target the bacterial capsule, causing it to swell or undergo a visible increase in size.

   In this technique, a small sample of bacteria is mixed with the specific antiserum and observed under a microscope. If the bacteria possess a capsule that reacts with the antiserum, the capsule will significantly enlarge or swell, allowing for its identification. This swelling is detected by an experienced microbiologist who visually confirms the presence of the capsule.

   The Quellung reaction is particularly useful in identifying encapsulated bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis. These bacteria cause various diseases, including pneumonia, meningitis, and other respiratory infections. By performing the Quellung reaction, healthcare professionals can determine the presence of these encapsulated bacteria, aiding in accurate diagnosis and appropriate treatment selection.

   Overall, the Quellung reaction is a crucial laboratory technique that plays a vital role in the identification of specific bacteria with capsules. It provides a visual confirmation of capsule presence, helping microbiologists and healthcare professionals in their efforts to understand and combat infectious diseases caused by these particular bacterial strains.
