GAFFKY SCALE OR TABLE Meaning and Definition

1. The Gaffky scale or table is a classification system used in microbiology to differentiate and classify bacteria based on their appearance and characteristics under a microscope. Named after Karl Friedrich Wilhelm Ludwig Gaffky, a German bacteriologist, it was developed in the late 19th century and remains a foundational tool in the field.

   The Gaffky scale consists of a numerical system ranging from 1 to 6, with 1 indicating pure and well-defined bacterial colonies, while 6 denotes completely invisible or non-growable colonies. This scale enables the quantification and categorization of bacteria according to their morphological features and staining properties.

   By analyzing the microorganisms' colonial appearance, Gaffky's scale allows scientists to assess the distinct characteristics of various bacterial species. These properties include colony size, shape, margin, elevation, opacity, and pigment production, in addition to other relevant microbiological parameters. Bacterial colonies are visually observed on agar plates or other culture media and compared to standard descriptions or photographs in the Gaffky table.

   This classification system aids microbiologists in identifying and classifying bacteria more accurately, facilitating research, clinical diagnostics, and the understanding of disease-causing microorganisms. It provides a standardized language for describing and communicating bacterial characteristics, making it an essential instrument in the field of microbiology. The Gaffky scale has been widely used and referenced in the identification and classification of bacteria, contributing to the field's overall progress and understanding of microbial diversity.

2. A formula for the classification of cases of tuber-culosis according to the number of tubercle bacilli in the sputum. The following is the table as modified by Lawrason Brown: (1) One to four bacilli in whole preparation; (2) one on an average in many fields; (3) one on an average in each field; (4) two to three on an average in each field; (5) four to six on an average in each field; (6) seven to twelve on an average in each field; (7) thirteen to twenty-five on an average in each field; (8) fifty on an average in each field; (9) one hundred on an average in each field.
