Identifies bacteria/fungus present (most of the time) Sensitivity results based on lab data Human vs lab. WHAT IT DOES NOT TELL YOU Does not identify infection vs colonization vs contamination Don’t treat colonization or contamination. Does not tell you which antibiotic to Size: KB. INTRODUCTION TO BACTERIOLOGY AND BACTERIAL STRUCTURE/FUNCTION LEARNING OBJECTIVES using the pure culture.
Reisolate the bacteria in pure culture from the experimental infection. These rules cannot be applied to all infectious diseases. Some infectious diseases, such as (A Summary Chart) CHARACTER PROCARYOTIC EUCARYOTIC Nuclear. Bacteria live in communities • Bacteria are usually found in large multi-species communities • In their natural environment they coexist with other bacteria, fungi, protozoans and viruses • Specific bacteria must be isolated from the community in order to study their properties • For instance, a specific species that causes disease or.
Inoculation of the media with the prepared culture. Incubation of cultures and sampling during growth. Sterilisation and safe disposal of all cultures and decontamination of all contaminated equipment.

Adults (2-bottle set): Collect blood using blood collection set and adapter cap, following instructions on procedural chart included in kit. Steps in diagnostic isolation and identification of bacteria. Step 1.
Samples of body fluids (e.g. blood, urine, cerebrospinal fluid) are streaked on culture plates and isolated colonies of bacteria (which are visible to the naked eye) appear after incubation for one to several days (Figure 1). Each colony consists of millions of bacterial cells.
The Fundamentals of Bacteriology. This book covers the following topics related to bacteriology: Historical Introduction, Position of Bacteria, Relationships to Algae, Yeasts, Molds, Protozoa, Morphology, Physiology, The study of bacteria: Culture Media, Methods of Using Culture Media, Isolation of Bacteria in Pure Culture, Study of the Morphology of Bacteria, Study of the Physiology of.
Knowledge of bacterial identification from the Gram film appearance helps predict the cause of an infection from the microscopy result up to 48 hours before the culture result is available. By using both the Basic Bacteria Identification diagrams and the Table of Bacterial Causes of Infection (following diagrams) you can identify the likely.
Catalase – this test determines bacterial production of catalase enzymes. Place a drop of hydrogen peroxide (3% H2O2 - reagent grade) on a microscope slide or in the concave surface of a hanging drop slide. With a sterile loop, collect a sample of hour old pure bacterial culture.
Place the loop in the hydrogen peroxide. two bacteria are examined for their metabolic (or biochemical) characteristics, the microbiology log book in numeral order. The number assigned to the specimen is written on the specimen container and the requisition form, culture media containers, and culture media plates.
In addition, date and time. Cover different classification schemes for grouping bacteria, especially the use of the Gram stain 2. Describe the different types of bacteria 3. Discuss bacterial structure and the function of the different bacterial components 4.
Discuss the distinguishing characteristics of Gram positive and Gram negative bacteria. Classification of Bacterial Culture media on the basis of purpose/ functional use/ application. Many special-purpose media are needed to facilitate recognition, enumeration, and isolation of certain types of bacteria.
To meet these needs, numerous media are available. Bacteria are generally studied when fixed and stained. Smears or films of bacterial cultures and clinical specimens are usually fixed by heat, the slide being first throughly dried in air and then heated gently in a flame.
Vegetative bacteria are thereby killed, attached to the surface of the slide and preserve from undergoing autolytic changes. The traditional phenotypic tests are commonly used in actinobacterial identification.
They constitute the basis for the formal description of taxa, from species and subspecies up to genus and family. The classical phenotypic characteristics of actinobacteria comprise morphological, physiological, and biochemical features.
The morphology of actinobacteria includes both cellular and colonial. This book is not available. Out of Print--Limited Availability. This chart visually and textually shows three ways bacteria can cause damage to the body and explains the basic structure of bacteria, the types of pathogenic bacteria, and the sites of infection.
Bacterial Culture Media MICROBIOLOGY MODULE Microbiology Notes Neisseria sp. Serum for medium can be obtained from animal blood but must be filtered through membrane or seitz filter before use.
Selective and enrichment media are designed to inhibit unwanted commensal or contaminating bacteria and help to recover pathogen from a mixture of. Address: P.O. Box Batavia, IL Phone: Fax: Email: [email protected] potential viral and bacterial etiologies. Each respiratory pathogen requires a unique set of specimen types, collection methods and handling conditions to optimize diagnostic yield.
Because these guidelines are designed for detection of multiple pathogens, the sensitivity of. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations.
Smil takes readers from bacterial invasions through animal metabolisms to megacities and the global economy. Culture, Aerobic Bacteria - Aerobic bacteria cause a variety of human infections.
Proper specimen collection and transport, media and incubation are important criteria for the recovery of aerobes. The primary aerobic bacterial agents of skin and tissue infections include S.
aureus, P. aeruginosa, members of the enterobacteriaceae, and beta-hemolytic streptococci. Introduction • Prokaryotic organisms.
• Vary in sizes, measure approximately to μm • Widely distributed. It can be found in soil, air, water, and living bodies. • Some bacteria can cause diseases for human, animals and plants. • Some bacteria are harmless (i.e.
live in human bodies as normal flora). the bacterial cell wall, as well as, to some extent, the chemical composition. Gram-Positive bacteria have thick, dense, relatively non-porous walls, while Gram-Negative bacteria have thin walls surrounded by lipid-rich membranes.
Some non-bacterial organisms with thick cell walls (e.g., some yeasts) also stain Gram-Positive. Using sterile loop, streak a loopful of bacterial culture onto the agar plate. Incubate at 37 o C for hours.
Day 2: Pick up a single colony of each strain from the agar plate and inoculate it into a test tube containing 10 ml of autoclaved broth. Incubate the test tube overnight at 37 o C. If a culture is indole negative, the reagent layer will remain yellow or be slightly cloudy. Indole positive bacteria: E.
coli, Vibrio cholera Indole negative bacteria: Klebsiella, Salmonella, Shigella spp. Fig. (e) Citrate Test Purpose The citrate test screens a bacterial. Types of culture media used in microbiology. Media are of different types on consistency and chemical composition.
On Consistency: 1. Solid Media. Advantages of solid media: (a) Bacteria may be identified by studying the colony character, (b) Mixed bacteria can be separated. Solid media is used for the isolation of bacteria as pure culture. Bacterial culture media One of the most important reasons for culturing bacteria in vitro is its utility in diagnosing infectious diseases.
Isolating a bacterium from sites in body normally known to be sterile is an indication of its role in the disease process. Culturing bacteria is also the initial step in studying. In microbiology, McFarland standards are used as a reference to adjust the turbidity of bacterial suspensions so that the number of bacteria will be within a given range to standardize microbial testing.
An example of such testing is antibiotic susceptibility testing by measurement of minimum inhibitory concentration which is routinely used in medical microbiology and research.

Culture characteristic of bacteria 1. Culture characteristic of bacteria Prepared by Samira Fattah Assis.
Lec. College of health sciences-HMU Lab 6 2. • Bacteria grow on solid media as colonies. • A colony is defined as a visible mass of microorganisms .There are several types of bacterial culture methods that are selected based on the agent being cultured and the downstream use.
Broth cultures. One method of bacterial culture is liquid culture, in which the desired bacteria are suspended in a liquid nutrient medium, such as Luria Broth, in an upright allows a scientist to grow up large amounts of bacteria for a variety of.
