Classification of microorganisms-MICROBIOLOGY QUICK LEARNSaajida Sultaana
This document discusses the classification of microorganisms. It describes how living things have historically been classified by scientists like Aristotle and Linnaeus. Taxonomy is defined as the science of biological classification, which involves classifying organisms into a hierarchical system of taxa based on similarities. The modern system involves three domains - Archaea, Bacteria, and Eukarya - classified according to cell structure and rRNA. This three domain system replaced earlier kingdom-based systems and better reflects evolutionary relationships between domains.
The document summarizes the early history and development of microbiology. It discusses key figures like Antoni van Leeuwenhoek who first observed microorganisms under a microscope. Later scientists like Louis Pasteur and Robert Koch helped establish germ theory and methods of scientific investigation. Their work answered questions about spontaneous generation and the role of microbes in fermentation and disease. Modern microbiology applies genetic and molecular techniques to study microbial functions, interactions, and applications in areas like biotechnology and medicine.
There are two main categories of living organisms - prokaryotes and eukaryotes. Prokaryotes are unicellular organisms that lack membrane-bound organelles and a nuclear membrane, while eukaryotes can be unicellular or multicellular and have internal membrane-bound structures and a nuclear membrane. The document provides details on the distinguishing characteristics of prokaryotic and eukaryotic cells.
This document is a PowerPoint presentation on cell structure and function. It begins by defining the basic processes of life in cells, including growth, reproduction, responsiveness, and metabolism. It then distinguishes between prokaryotic and eukaryotic cells, noting that prokaryotes lack nuclei and membrane-bound organelles while eukaryotes have these structures. The presentation goes on to describe the various external structures of bacterial cells, including glycocalyces, flagella, fimbriae, and pili. It also explains bacterial cell walls, membranes, and cytoplasmic structures. In addition, it covers similar structures in archaea like glycocalyces and flagella.
The document discusses microbial growth requirements and culturing techniques. It explains that microbes require nutrients, including sources of carbon, energy, and electrons, as well as physical factors like temperature, pH, water activity, and oxygen levels. Microbes are classified based on their carbon, energy, and electron sources. The document also describes how biofilms form and their importance. Finally, it outlines methods for obtaining pure cultures, including streak plating and pour plating, and discusses common culture media used to grow microorganisms.
The document summarizes the key differences between prokaryotic and eukaryotic cells. Prokaryotic cells were the first life on Earth and lack membrane-bound organelles. Eukaryotic cells are larger, with organelles like the nucleus that houses DNA. The main difference is compartmentalization into membrane-bound structures in eukaryotes. Specific organelles like mitochondria, the endoplasmic reticulum, Golgi apparatus and chloroplasts are only present in eukaryotic cells. Eukaryotic cells also have a cytoskeleton, larger ribosomes, vesicles and vacuoles not seen in prokaryotes.
This document discusses methods for isolating and cultivating animal and plant viruses. There are three main methods for animal viruses: embryonated chicken eggs, tissue cultures, and laboratory animals. Embryonated chicken eggs are commonly used as they provide several inoculation sites and are economical. Tissue cultures include primary cell cultures from animal tissues, diploid cell strains with normal chromosome numbers, and continuous cell lines with abnormal numbers that can undergo infinite divisions. Laboratory animals like primates and small mammals are also used but their use is now limited. For plant viruses, whole plants, plant tissue cultures, and protoplast cultures are used, with protoplasts being a standard technique. Insect cell cultures can also be used
This document compares and contrasts prokaryotic and eukaryotic cells. Prokaryotes like bacteria have circular DNA not enclosed in a nucleus, lack membrane-bound organelles, and divide through binary fission. Eukaryotes have DNA within a nucleus, several membrane-bound organelles, and divide through mitosis. Prokaryotes come in coccus, bacillus, and spiral shapes and have cell walls containing peptidoglycan. Eukaryotes possess flagella, cilia, and internal structures like the cytoskeleton, nucleus, and mitochondria. The endosymbiotic theory proposes that eukaryotic cells evolved from prokaryotes living together.
Viruses are non-living parasitic entities that can only reproduce by infecting a host cell. They contain either DNA or RNA surrounded by a protein coat and come in various shapes. Viruses infect a wide diversity of organisms like humans, causing diseases such as AIDS, chickenpox, and herpes. They spread through direct or indirect contact between hosts, through bodily fluids or contaminated surfaces. Vaccines help prevent the spread of viruses by exposing the immune system to weakened or dead forms of viruses.
Presentation comprises of introductory information on virus, related terminology, its composition and structure, classification, nomenclature and taxonomy for under graduate students.
Viruses consist of nucleic acid surrounded by a protein coat. They can only replicate inside host cells by using the host's cellular machinery. There are two main cycles by which viruses replicate - the lytic cycle which results in host cell death and release of new virus particles, and the lysogenic cycle where the viral genome integrates into the host genome and is copied along with it until induced to enter the lytic cycle. Retroviruses like HIV are unique in that they reverse transcribe their RNA genome into DNA which then integrates into the host cell genome.

Flagella are thin, thread-like appendages that protrude from bacterial cells and enable locomotion. They vary in number, arrangement, and length depending on the bacterial species. A flagellum is composed of three main parts - a long, helical filament; a basal body that anchors the flagellum and acts as a motor; and a short, curved hook that connects the filament to the basal body. Flagella rotate like propellers via a motor system that uses proton gradients to drive the rotation of the basal body and propel the bacterium forward.

The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to form urine and regulate electrolyte and fluid levels. Each kidney contains nephrons, the functional filtering units, composed of a glomerulus and renal tubule. Urine is formed through glomerular filtration, tubular reabsorption of useful substances, and tubular secretion of wastes. The ureters carry urine from the kidneys to the bladder, where it is stored and then expelled through the urethra.
The document summarizes key aspects of the digestive system, including its main divisions and functions. The digestive system breaks down food mechanically and chemically. Mechanical digestion increases surface area through processes like chewing, while chemical digestion involves enzymes that break molecules into simpler compounds. Digestion occurs along the alimentary tube from the mouth to anus, aided by accessory organs like the liver, pancreas and gallbladder. The end products of digestion, like carbohydrates, proteins and fats, are absorbed and used by cells.
The respiratory system includes the nose, pharynx, larynx, trachea, bronchi, lungs, and diaphragm and intercostal muscles. The lungs are the site of gas exchange between inhaled air and blood in the pulmonary capillaries. Oxygen diffuses into the blood and carbon dioxide diffuses out. The respiratory centers in the medulla and pons control breathing and respond to changes in blood oxygen and carbon dioxide levels. Diseases can disrupt lung function and acid-base balance.
