Johannes Karl Fink, in Petroleum Engineer's Guide to Oil Field Chemicals and Fluids, Bacteria. Instead of using polymers, the addition of bacterial cultures, which may form natural polymers that could then prevent fluid loss, has been suggested.. In one study, a bacterial culture selected for its abundant exopolymer production was added to drilling mud, to determine whether the. BACTERIAL CULTURE TECHNIQUES If working from stab culture: a. Grasp the bottom of the E. coli culture vial between thumb and two fin-gers of free hand. Remove vial cap using little finger of same hand that holds inoculating loop. Avoid touching rim of cap. b. Quickly pass mouth of vial several times through burner flame. Differential media contain dyes that react with the chemical processes of certain types of bacteria, allowing their identification.. Characteristics of bacterial colony growth are described in terms of shape, appearance, and color.. The differences in DNA sequence can be used to identify organisms. Marker genes include, but are not limited to, ribosomal RNA (16S in bacteria and archaea and 18S.   Bacterial colonies are frequently shiny and smooth in appearance. Other surface descriptions might be: veined, rough, dull, wrinkled (or shriveled), glistening. 1c. Color – It is important to describe the color or pigment of the colony.

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.

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.
