Microbiology Tests

A Stool Culture is a laboratory test that examines a stool sample for the presence of bacteria, viruses, parasites, or other microorganisms that can cause gastrointestinal infections. It helps identify the specific organism causing the infection and determine the most effective treatment. Stool Cultures are commonly used to diagnose bacterial infections such as Salmonella, Shigella, Campylobacter, and Escherichia coli (E. coli) infections. They can also detect certain viral and parasitic infections. The test involves placing a small amount of stool sample in a special growth medium and observing the growth of microorganisms over a few days.

The KOH (potassium hydroxide) test is a simple laboratory procedure used in microbiology and dermatology to identify fungal infections. It involves mixing a sample of skin, hair, or nail material with a solution of KOH, which helps dissolve human tissue, leaving fungal elements like hyphae and spores visible under a microscope.

The Mycobacterium Combined Panel Test is a diagnostic tool used to detect various strains of mycobacteria, including tuberculosis.

A Sputum AFB (Acid-Fast Bacilli) Test is a diagnostic tool used to detect the presence of Mycobacterium tuberculosis, the bacterium responsible for tuberculosis (TB), in a patient's sputum, which is mucus and other matter expelled from the respiratory tract. This test helps in the early diagnosis and treatment of TB.

During the test, a sample of vaginal discharge is collected, smeared on a slide, stained with specific dyes, and examined under a microscope to identify bacteria and their arrangement.

The Gram Stain Test is a microbiological technique used to categorize bacteria into two major groups: Gram-positive and Gram-negative, based on their cell wall characteristics.

No, pubic lice are specific to humans and cannot be transmitted by pets.

Medical professionals diagnose STEC through stool culture, which can identify the presence of the bacteria. Additionally, specific tests can detect the Shiga toxins or their genetic material. It's essential to consult a healthcare provider if you suspect STEC infection, as prompt diagnosis and treatment are critical.
