ASEPTIC TECHNIQUE AND BACTERIAL ANATOMY AND MORPHOLOGY

Introduction

Part I: Aseptic Technique

The purpose of this experiment is to become familiar with the specific microbiological technique known as the aseptic technique, which is used to avoid contaminating cultures.

In this case a pure culture of an unknown organism was introduced to a sterile medium of Phenol Red Glucose Broth Durham. The culture was obtained from a 52-year old male truck driver who is complaining to his doctor about pain in his lower abdominal and back. With a family history of prostate cancer, he worried that his sudden need to urinate during the night and infrequent appearance of blood in his urine might be bad signs. An ultrasound scan determined that the prostate gland was swollen. The physician sent a urine specimen to the lab for analysis. This organism was detected in large numbers in the urine.

After performing the aseptic techniques, it was found that if the proper techniques are not performed within a certain time frame the specimen will become contaminated.

Part II: Bacterial Anatomy

The purpose of this experiment is to become familiar and gain an understanding of how morphology and the arrangement of bacteria relate to staining techniques.

Sample 1

In this study a female patient who had a problem that had arisen suddenly after lunch, had allergic reaction to something that she ate or drank had sent her to the bathroom with cramps and copious diarrhea. She knew she was violently allergic to wheat gluten, but the waiter had assured her that the meal was wheat gluten-free. Her lawyer-husband had his investigators at the restaurant before they closed that night, testing for any evidence that would uncover the cause. This is one of the organisms that the investigators found in the dishes she had that day.
A sample of the unknown organism was used to perform a gram stain procedure.

Sample 2

In this study a dead goat was found in

    Specific bacterial morphologies noted in exercise one come from the spiral bacteria sample. The shape appears to be corkscrew in nature and vary in length throughout the sample slide. The length varies but the width seems to be uniform. The color most likely arises from the stain used to allow for better visualization of the organism. The Bacillus sample has no discernable morphology and appears as round ended, and cylindrical shaped in nature. The organisms have a black tint which is probably related to the type of statin used for visualization of the organism.…

    B: On each examples bacterial morphologies are visible and easy identified. In the wet mount example with yeast, cocci is noted, while is hard to determine in cheek smears. Check smear and yeast smear contain cocci with direct staining. At direct staining plaque smear contain cocci and bacillus. Yeast with indirect staining contains cocci as well. On same picture bacteria are singled while on some pictures bacteria are in group and uneven clusters. Different type of stain plays role to differentiate the shape of bacteria.…

    Bacteria are inoculated (introduced) and cultured (grown) in the laboratory for test studies to determine their morphology (the shape, size, arrangement, and internal structures) and pathology (ability to cause disease). Inoculation has to be performed without adding other microbes or contaminants. Aseptic (sterile) technique is the process of growing pure (uncontaminated) cultures, and is essential for proper characterization of a bacterium. Aseptic technique includes the use of sterile media and equipment. The sterility of these tools is maintained by proper handling procedure, which prevents the introduction of contamination. The basics of aseptic technique are:…

    The purpose of this experiment is to distinguish and indentify an unknown bacterium. There are several tests that can help one eliminate and narrow down the options. The most useful test, and the very first one done, is a gram stain. This test will tell whether the bacterium is gram-positive or gram-negative. After the type of gram stain is identified, the tester has a wide array of differentiating tests at their disposal. Based on the results from these tests, and the numerous others that are available, one can accurately establish the identity of an unknown bacterium.…

    The possible identity of the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett, 2012; Kellenberger, 2001). Based upon the results, both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger, 2001). In order to isolate the two different bacteria, colonies that grew on the MSA were used to inoculate Gram-positive tests, where as MacConkey Agar colonies were used to inoculate Gram-negative tests.…

    There are several different medical reasons for identifying microorganisms. The reasons may vary from having to know the causative agent of a disease in a patient to be able to treat and care for them properly, to knowing the correct microorganism to be used for making certain antibiotics as well as proper dosages, down to knowing all microbes associated with consumed foods such as plants and animals in case of an allergen or a contamination outbreak. This analysis was done by utilizing all of the proper methods taught thus far in the microbiology laboratory for the identification of two unknown bacteria.…

    Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons, such as knowing the causative agent of disease, knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study. This study allows the student to exercise their ability to use and understand sterile techniques, transmission, and prevention of microorganisms.…
