Instructions for Identifying Unknown Bacteria. Step 1: Isolate the Two Bacterial Species & Do Initial Gram Stain. Note. Step 2: Characterize Bacterial Colonies, Create Stock Cultures of Isolated Bacteria, & Do Gram Stain on Isolates. Note. Step 3: Follow the Flow Chart to Identify Bacterial Species. Note. The Gram stain differentiates organisms by the way the react with colored stains: Gram-negative rods (L) stain pink/red; Gram-positive rods (R) stain blue/purple.. Given the wealth of agar media, microscopy stains, and biochemical tests, microbiologists have built flow charts to identity the bacteria surrounding us. Yet, the numerous growth. This capsule helps prevent white blood cells (which fight infection) from ingesting the bacteria. Under the capsule, gram-negative bacteria have an outer membrane that protects them against certain antibiotics, such as penicillin. When disrupted, this membrane releases toxic substances called endotoxins. Endotoxins contribute to the severity of. Gram-negative bacteria (GNB) are among the world's most significant public health problems due to their high resistance to antibiotics. These microorganisms have significant clinical importance in hospitals because they put patients in the intensive care unit (ICU) at high risk and lead to high morbidity and mortality.[1][2] Two large groups, Enterobacteriaceae and the non-fermenters, are.

Gram staining is a diagnostic test that gives an early indication of potential bacteria through visualization of the bacteria. The Gram stain helps to differentiate the organism, whether it is gram-positive or gram-negative. 50 Gram-positive bacteria appear purple in color and gram-negative bacteria appear pink. In addition, the shape. Description. This eLearning course familiarizes laboratory professionals with how to read a Gram stain, colonial characteristics, and biochemical tests used to identify Gram negative microorganisms as well as commonly used testing algorithms. The course only covers aerobic microorganisms, those that grow in the presence of oxygen. Oxidase negative, Catalase negative or weakly positive Brucella spp: Oxidase positive, Urease positive, Catalase positive Indole (+)* Escherichia coli, Klebsiella oxytoca, Citrobacter divers us, Edwardsiella tarda Indole (-) * Cronobacter spp. , Klebsiella pneumoniae, Enterobacter aerogenes, Enterobacter cloacae, Hafnia alvei Oxidase (+)* Gram stain and bacterial morphology: Of all the different classification systems, the Gram stain has withstood the test of time. Discovered by H.C. Gram in 1884 it remains an important and useful technique to this day. It allows a large proportion of clinically important bacteria to be classified as either Gram positive or negative based on their

For example, the use of MALDI-TOF MS to rapidly identify Gram-negative organisms from subculture contributed to a 51-h reduction in the time to optimal therapy and a 17% reduction in 30-day mortality in patients with Gram-negative BSI . Importantly, 61.4% of the antibiotic modifications were based on organism identification alone.
