5 Essential Tips on Extending the Lifespan of Your Microscope

If you’re of a certain age, you probably remember your parents telling you not to sit too close to the TV screen or “you’ll ruin your eyes.” If you’re of a decidedly younger age, you probably remember your parents telling you to take a break from the iPhone or tablet…

RNA-seq: Introduction, Applications and Protocols

The identification and quantification of gene expression levels have unveiled the complexity of many biological mechanisms within the cell. The widespread knowledge about cell transcriptome has been accomplished through the RNA sequencing (RNA-Seq) method. This method detects the presence of RNA molecules by using the capabilities of high-throughput sequencing. Also,…

Antibiotic resistance is a curse to the present world

Antibiotics saved thousands of people in 1950s and 1960s. But for decades these antibiotics show lower efficacy against microbial infections. Antibiotic resistance is now one of the most concerning issues in the present world. It is suspected that we are turning back into the pre-antibiotic era, in which no effective…

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…

GUT FEELING INDUCED BY GUT FLORA

“Gut flora is a complex community of organisms that inhabit human and animal digestive system”. Relation between humans and gut flora is mutualistic. Bacteria in the digestive system assist in nutrient metabolism, vitamin production, and waste processing. They also aid in the host's immune system response to pathogenic bacteria.

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…

MORPHOLOGY OF PLATELETS

Platelets are small, 1-3 μm in diameter, purple structures with tiny irregular projections on surface. In blood films prepared from non-anticoagulated blood (i.e. direct fingerstick), they occur in clumps. If platelet count is done on automated blood cell counters using EDTA-anticoagulated blood sample, about 1% of persons show falsely low…

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,…

WHITE BLOOD CELLS MORPHOLOGY

Approximate idea about total leukocyte count can be gained from the examination of the smear under high power objective (40× or 45×). A differential leukocyte count should be carried out. Abnormal appearing white cells are evaluated under oil-immersion objective.   Morphology of normal leukocytes (see Figure 800.1):   Polymorphonuclear neutrophil:…

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…
