- A bacterial wound culture is primarily ordered to help determine whether a wound is infected, to identify the bacteria causing the infection, and to prepare a sample for susceptibility testing where required.

Sputum culture A sputum culture is done to: 1  Find and identify bacteria or fungi that are causing an infection (such as pneumonia or tuberculosis) of the lungs or the airways leading to the lungs. 2  Identify the best antibiotic to treat the infection (sensitivity testing). 3  Monitor treatment of an infection. sample of sputum is placed in a container with substances that promote the growth of bacteria or fungi. If no bacteria or fungi grow, the culture is negative. If organisms that can cause infection grow, the culture is positive.

How can you identify bacteria on agar plates? You generally cannot, with any degrees of certainty, identify bacteria solely based on gross inspection of an agar plate. Generally to identify a bacteria you will go through many stains, specialized agars, and other tests to know for sure what organism that you have in front of you. This gives you a very good idea of how the process normally works.

The importance of identifying unknown bacteria? For example, if a bacteria can make a person ill, but it has something called a beta-lactam ring in its cell wall, that is good to know because a drug that works on the beta-lactam ring is able to kill the bacteria.Unknown bacteria may also have clinical uses.eport Abuse. The importance of identifying unknown bacteria is very important for one reason, bacteria does not stay in the same form, it's mutating all the time.

- They can affect your skin, your blood, an organ in your body or your gastrointestinal tract. The number of people who acquire an antibiotic resistant bacteria grows each year, and the number of deaths from these infections is also growing. Therefore, it is important to learn how to prevent bacterial infections.If you think that you have a bacterial infection, it is important to seek medical attention right away to get treatment. By using some simple strategies and changing a few small habits you can reduce your chances of getting a bacterial infection. Avoid kissing or sharing eating utensils with someone who has the flu, a cold, mononucleosis, or a known bacterial infection. 2  Do not smoke and avoid exposure to second hand smoke. 3  Use a humidifier if the air in your home is dry.

Chlamydia Testing Chlamydia testing identifies the bacteria Chlamydia trachomatis as the cause of a person's infection. Screening for, diagnosing, and treating chlamydia is very important in preventing long-term complications and spread of the infection to others.

Diagnosing Urinary Tract Infections in Dogs The gold standard for diagnosing urinary tract infections is culture and sensitivity. Cultures should be performed on sterile samples ideally obtained by cystocentesis, to reduce the chance of contamination. Culture is also highly recommended for infections that are treated with but unresponsive to antibiotics.

MRSA The diagnosis of MRSA is established by culture of the bacteria from an infected area. Any area of the skin with pus, abscesses, or blisters should be cultured for MRSA. Patients with sepsis or pneumonia should have blood cultures drawn. Pus from surgical sites, bone marrow, joint fluid, or almost any body site that may be infected should be cultured for MRSA.

Diagnosis 1 Take a sample of vaginal secretions. This may be done to check for an overgrowth of anaerobic bacteria in your vaginal flora. Your doctor may examine the vaginal secretions under a microscope, looking for clue cells, vaginal cells covered with bacteria that are a sign of bacterial vaginosis.  Test your vaginal pH. Your doctor may check the acidity of your vagina by placing a pH test strip in your vagina. A vaginal pH of 4.5 or higher is a sign of bacterial vaginosis.

- 1 Doctors rely on sensitivity analysis to help treat bacterial infections.  The test helps your doctor figure out what treatment is needed to kill the bacteria. It also helps them to see if the bacteria are resistant to certain drugs.

- Doctors diagnose bacterial vaginosis by asking about the symptoms, doing a pelvic exam, and taking a sample of the vaginal discharge. The sample can be tested to find out if you have bacterial vaginosis. Bacterial vaginosis usually does not cause other health problems. But in some cases it can lead to serious problems.

- Design a dichotomous pathway that could be used to identify a bacterial sample if the bacteria is known to be one of the following gram positive bacteria. The tests used in the pathway should be chosen from the tests included in the expected test results attached to this exercise. All branches of the pathway should be completed to allow full differentiation of all bacteria included in the list.

- Tests: 1  A chest x-ray may show signs of infection in your lungs. 2  Blood tests can help healthcare providers learn more about your bacterial pneumonia. 3  A mucus sample is collected and tested for the germ that is causing your illness.

Sepsis (Blood Poisoning) How is it used? Blood cultures are used to detect the presence of bacteria or fungi in the blood, to identify the type present, and to guide treatment. Testing is used to identify a blood infection (septicemia) that can lead to sepsis, a serious and life-threatening complication.

- Other related tests that may be performed include: 1  Gram stain—a relatively quick test used to detect and identify the general type of bacteria.  Susceptibility testing—determines the drug (antimicrobial) that may be most effective in treating the infection.

New Reference Laboratory Parameters Help Identify Urinary Tract Infection As with all diseases, both clinical and laboratory findings should be integrated to make the best possible interpretation of all information. Three IDEXX reference laboratory tests aid in diagnosing UTI: urine culture (#4035), urinalysis (#910), and urine culture if (#943) . The definitive diagnosis of UTI is based on the culture of bacteria from a sterilely collected urine sample. Infection is indicated when organisms grow from an uncontaminated sample.

Urinary Tract Infection in Adults Bacteriuria - this refers to the presence of bacteria in the urine. This may be symptomatic or asymptomatic. Asymptomatic bacteriuria should be confirmed by two consecutive urine samples. Urinary tract infection (UTI) - this implies the presence of characteristic symptoms and significant bacteriuria from kidneys to bladder. Many laboratories regard 105 colony-forming units per millilitre (cfu/ml) as the threshold for diagnosing significant bacteriuria.

Tests for Bacterial Vaginosis Several tests can be used to find bacterial vaginosis: 1  Wet mount. 2  A sample of vaginal discharge is mixed with a salt solution on a microscope slide. 3  The slide is checked for bacteria, white blood cells, and unusual cells called clue cells. 4  If clue cells are present, it means bacterial vaginosis may be present.

Microscopy The clinician orders a stain based on the likely pathogens, but no stain is 100% specific. Most samples are treated with Gram stain and, if mycobacteria are suspected, with an acid-fast stain. However, some pathogens are not easily visible using these stains; if these pathogens are suspected, different stains or other identification methods are required. Because microscopic detection usually requires a microbe concentration of at least about 1 × 10 4-5 /mL, most body fluid specimens (eg, CSF) are concentrated (eg, by centrifugation) before examination.
