The purpose of a microbiology incubator is to mimic the natural growth conditions required for the microorganisms, providing them with the right temperature, humidity, and other environmental parameters necessary for their growth and survival.
There are several types of autoclaves, including gravity displacement, pre-vacuum, and steam-flush autoclaves. Gravity displacement autoclaves remove air from the chamber by displacing it with steam, while pre-vacuum autoclaves use a vacuum pump to remove air prior to introducing steam.
The negative staining is preferred in cases when the bacterium does not stain well (e.g. some of the spirochetes) or when it is desirable to confirm observations made on the shape and size or Morphology of the bacteria observed either in a wet mount or hanging drop preparations etc.
Microtomy or section cutting is the technique of making the very thin slices of tissue specimens for the microscopic examination to identify the abnormalities or atypical appearance in the tissue (if present) and also for the study of various components of the cells or tissues like Lipids, Enzymes......
BIOCHEMICAL TESTS FOR STAPHYLOCOCCUS AUREUS (S. aureus) There are so many biochemical tests for Staphylococcus aureus, the well known causative agent of localized suppurative lesions.
The simplest artificial media which are commonly used in the laboratories are Nutrient Broth medium & Nutrient Agar Medium, also known as the Basal Media. These media provide all the basic components that are required by the bacterial cell for the rapid growth in the laboratory.
Besides being a Differential solid medium, MacConkey Agar Medium is a selective and differential medium too and primarily used for the isolation of Gram-negative and enteric bacilli, the rod-shaped bacteria. Moreover, MAC is the most commonly used media for the differentiation of Lactose fermentors.....
Red cell indices include 3 tests – Mean Cell Volume (MCV), Mean Cell Hemoglobin (MCH), and Mean Cell Hemoglobin Concentration (MCHC). They are also called the “Absolute values” for Red Blood Cells. The Values of MCV, MCH, and MCHC are derived from the values of Hemoglobin, Packed Cell Volume (PCV) or Hematocrit and Red Cell Count.
