Biology

Biology is the branch of science that primarily deals with the structure, function, growth, evolution, and distribution of organisms. It’s a methodological study of life and living things.

Biology is the scientific study of life. It spans multiple levels, from biomolecules and cells to organisms and populations12. All living things share common biological phenomena, such as reproduction, cell division, and the transmission of genetic material.

Beta Lactamase Test

Beta (β) Lactamase Test: Principle, Types, Procedure, Results

Biology /

Beta Lactamase Test is a crucial diagnostic tool that determines if bacteria have beta-lactamase enzymes. Certain bacteria manufacture these enzymes to provide resistance to antibiotics that are beta-lactam, such as cephalosporins, carbapenems, monobactams, and penicillins. For the purpose of treating bacterial infections, especially those brought on by multi-drug resistant organisms, and directing efficient antimicrobial therapy, […]

Bacterial Conjugation

Bacterial Conjugation- Definition, Principle, Process, Examples

Biology /

Introduction of Bacterial Conjugation In bacterial conjugation, genetic material is directly transferred from one bacterium (the donor) to another (the receiver) through direct cell-to-cell contact. This process is known as horizontal gene transfer between bacteria. The pilus, a specialized structure that joins the two cells, aids in this process. The technique of direct genetic material

Bacterial Transduction: Definition, Principle, Steps, Examples

Biology /

Bacitracin Susceptibility The test is a microbiological technique designed to separate beta-hemolytic streptococci, namely Streptococcus pyogenes (Group A Streptococcus) from other streptococcal species. The test is based on bacteria’s sensitivity to the antibiotic bacitracin. What is Bacterial Transduction? Bacterial transduction is a type of horizontal gene transfer in which bacteriophages, or viruses that infect bacteria,

Bacterial Growth and Factors Affecting Growth of Bacteria

Bacterial Growth and Factors Affecting Growth of Bacteria

Biology /

Bacterial Growth refers to the increase in the number of bacterial cells in a population. This process occurs through binary fission, where a single bacterial cell divides into two genetically identical daughter cells. Bacterial Growth is not about the enlargement of individual cells but rather about the reproduction and increase in the cell population. Rather

Bacterial growth curve and its significance

Bacterial growth curve and its significance

Biology /

The bacterial growth curve represents the growth of a bacterial population over time in a closed environment (batch culture). It is typically divided into four distinct phases: lag phase, log (exponential) phase, stationary phase, and death (decline) phase. Each phase has specific characteristics and biological significance. The basic process of bacterial development has significant ramifications

Anatomical Position: Planes, Variations, Applications

Biology /

The anatomical position is the primary reference point in the discipline of anatomy, ensuring consistency and clarity in the description and study of the human body’s components and functions. This standardized stance, which consists of an upright posture, a forward-facing orientation, arms at the sides with palms forward, and feet together or slightly apart, enables

Baird Parker Agar Composition

Baird Parker Agar- Composition, Principle, Preparation, Results, Uses

Biology /

A specialized microbiological medium called Baird Parker Agar (BPA) was created by Baird-Parker in 1962 specifically for the purpose of isolating and counting Staphylococcus aureus. Because of its great selectivity and differential qualities, it has now established itself as a standard medium that is often used in food microbiology, clinical diagnostics, and environmental monitoring.
