Positive Gram stain results usually include a description of what was seen on the slide. This typically includes whether the bacteria are Gram-positive (purple) or Gram-negative (pink) as well as their shape — round (cocci) or rods (bacilli). Sometimes size, relative quantity and grouping of the bacteria, if relevant, are also reported Characteristics, Gram stain & Infection. Pseudomonas is a genus under the family Pseudomonadaceae. It consists of a large number of species (Gram-negative bacteria species) that exhibit different types of catabolic and metabolic characteristics. Because of this diversity, members of the genus Pseudomonas have varying relationships with several. Gram stains are usually scanned for the presence or absence of white blood cells (indicative of infection) and squamous epithelial cells (indicative of mucosal contamination). A sputum specimen showing >25 squamous epithelial cells/lpf, regardless of the number of white blood cells, is indicative that the specimen is grossly contaminated with.

  1. You swab the pus and make a slide, which you then send to the clinical lab for Gram staining. The lab sends back a report in which it is noted that the slide has many long chains of round cells that have stained purple in color. Based on the Gram staining, you suspect that the patient has a _____ infection
  2. Health professionals need to understand the important difference between gram-positive and gram-negative bacteria. Gram-positive bacteria are bacteria classified by the color they turn in the staining method. Hans Christian Gram developed the staining method in 1884. The staining method uses crystal violet dye, which is retained by the thick peptidoglycan cell wall found in gram-positive.

Gram Staining. The Gram stain procedure is a differential staining procedure that involves multiple steps. It was developed by Danish microbiologist Hans Christian Gram in 1884 as an effective method to distinguish between bacteria with different types of cell walls, and even today it remains one of the most frequently used staining techniques Gram-positive bacteria are classified by the color they turn after a chemical called Gram stain is applied to them. Gram-positive bacteria stain blue when this stain is applied to them. Other bacteria stain red. They are called gram-negative. Gram-positive and gram-negative bacteria stain differently because their cell walls are different

Gram Stain Test is a dyeing technique that helps in detecting the presence of bacteria or fungi in a fluid/cell sample, obtained from a site of suspected infection It also helps in a preliminary classification of the bacteria, which helps a physician initiate appropriate antibiotic therapy, before more 'time-consuming' confirmatory test. Staphylococcus aureus is a Gram-positive, round-shaped bacterium, a member of the Firmicutes, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin.It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen. Although S. aureus usually acts as a commensal of the. Anaerobic infection should be suspected when any wound smells foul or when a Gram stain of pus from an infected site shows mixed pleomorphic bacteria but aerobic cultures show no growth. Only specimens from normally sterile sites should be cultured anaerobically because commensal anaerobic contaminants may easily be mistaken for pathogens A sputum Gram stain is a laboratory test used to detect bacteria in a sputum sample.Sputum is the material that comes up from your air passages when you cough very deeply.

The Gram stain method is one of the most commonly used methods to rapidly identify the type of bacteria in a bacterial infection, including pneumonia Differential stains use more than one stain, and cells will have a different appearance based on their chemical or structural properties. Some examples of differential stains are the Gram stain, acid-fast stain, and endospore stain. You will learn how to prepare bacterial cells for staining, and learn about the gram staining technique

A Gram stain is a test used to help identify bacteria. The tested sample can be taken from body fluids that do not normally contain bacteria, such as blood, urine, or cerebrospinal fluid. A sample can also be taken from the site of a suspected infection, such as the throat, lungs, genitals, or skin PRINCIPLE OF GRAM STAIN. Crystal violet (gentian violet) serves as the primary stain, binding to the bacterial cell wall after treatment with a weak solution of iodine which serves as the mordant for binding the dye.; Some bacterial species, because of the chemical nature of their cell wall, have ability to retain the dye iodine complex even after treatment with an organic decolouriser such as. Abstract. Urinary tract infection (UTI) in children requires early diagnosis and treatment to prevent repeated UTI and renal scarring. This study aimed to evaluate the usefulness of the point-of-care Gram stain by physicians for suspected UTI in children at Okinawa Chubu Hospital as a rapid diagnostic test. A single-center, retrospective study. Urine infection: the Gram-staining can be used in the urine with suspected infection. The sample should be collected with care not to contaminate it with bacteria of the vagina or the foreskin. Urethritis : it is the most common sexually transmitted infection and tends to produce secretion through the urethra, which is collected to perform Gram. Biology questions and answers.

Definition (NCI_CDISC) A microscopy staining method for staining and identifying bacteria, based on the differential retention of a crystal violet-iodine complex within the cell membrane. Gram-positive organisms will appear blue-black or purple while Gram-negative organisms will appear red. Concepts Gram Stain Test- Reference Range. A gram stain test is used to identify bacteria. It is one of the most common ways to quickly diagnose bacterial infection in the body. Negative results of gram stain indicate no bacteria or only friendly bacteria were found A Gram stain is used to determine if bacteria are present in an area of the body that is normally sterile, such as spinal fluid. A sample from the infected area is smeared on a glass slide and allowed to dry. A series of stains are applied and then the stained slide is examined under a microscope where bacteria appear either purple (gram positive) or pink (gram negative) The purple color of the Gram stain, the shape and size of the microbe, the presence of blood cells (red and white, white indicating infection), and whether the microbe is found outside (extracellular) or inside of another cell (intracellular).
