Gram stain ( Gram staining or Gram's method ), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection. [1] . The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique in 1884. [2]
Escherichia coli O157:H7 is a serotype of the bacterial species Escherichia coli and is one of the Shiga-like toxin–producing types of E. coli. It is a cause of disease, typically foodborne illness, through consumption of contaminated and raw food, including raw milk and undercooked ground beef.
Dec 27, 2023 · Gram stain: Escherichia coli is a straight gram-negative short rod or bacilli; Escherichia coli cells are small rods 1.0-2.0 micrometers long, with a radius of about 0.5 micrometers. However, the size varies with the medium, and faster-growing cells are larger. E. coli is the most abundant facultative anaerobe in the colon and feces.
Jan 1, 2008 · INTRODUCTION. One of the fundamental problems in biology is the nature of cell cycle regulation. For this, Escherichia coli represents the ideal system since it is relatively simple, easily grown and manipulated, and its genome has been sequenced. Hundreds of genes that are involved in the cell cycle have been identified.
Feb 24, 2024 · Gram staining is a cornerstone technique in microbiology, crucial for differentiating between two major groups of bacteria based on their cell wall properties. Developed by Hans Christian Gram in 1882, this staining method has become a standardized protocol used in laboratories worldwide.
