Biological Oxygen Demand (BOD): Wastewater Treatment Methods for the Reduction of BOD

Biological Oxygen Demand (BOD) It is also known as Biochemical Oxygen Demand (BOD). It is defined as the amount of oxygen consumed during the process of degradation and eventual stabilization of unstable organic substances by the biochemical activities of aerobic and other microbes. This degradation of the chemical complex is…

Acid-Fast Staining: Purpose, Principle, Procedure and Observation

There are certain bacteria which cannot be stained by Gram's method. In 1882, Paul Ehrlich developed a method of staining such type of bacteria. This method was named, and still known as acid-fast staining and the bacteria were named as acid-fast bacteria. In the same year, Ehrlich's method was improved…

Gram Staining: Purpose, Principle, Procedure and Observation

In 1883 (originally published in 1884), Dr. Hans Christian Gram (1853-1938) developed a technique for the classification of bacteria into two broad groups, Gram-positive and Gram-negative. It is the most important staining technique for the classification and differentiation of bacteria. The Gram stain consist of four reagents; crystal violet (use…

EXAMINATION OF BLOOD SMEAR

A blood smear is examined for:   Red cells: Morphology, immature forms, inclusion bodies, arrangement of cells. White cells: Differential count, abnormal or immature forms. Platelets: Adequacy, abnormal forms. Parasites: Malaria, filaria.   A peripheral blood smear has three parts: Head, body, and tail. Also read: PREPARATION OF BLOOD SMEAR…

NUMERICAL ABNORMALITIES OF LEUKOCYTES

For meaningful interpretation, absolute count of leukocytes should be reported. These are obtained as follows:   Absolute Leukocyte Count = Leukocyte% × Total Leukocyte Count/ml     Neutrophilia:   An absolute neutrophil count greater than 7500/μl is termed as neutrophilia or neutrophilic leukocytosis.   Causes   Acute bacterial infections: Abscess,…

KOHLER ILLUMINATION

What is Kohler illumination? Kohler illumination is a method of adjusting a microscope in order to provide optimal illumination by focusing the light on the specimen. When a microscope is in Kohler, specimens will appear clearer, and in more detail. Process of setting Kohler Materials required Specimen slide (will need…
