Microorganism Speculation Pre-microbiology, the possibility that microorganisms existed was discussed for many centuries before their actual discovery in the 17 th century. 2. Phylogenetic Tree of the 3 Domains . Parasitology is the branch of Science which mainly deals about all the Parasites and its infectious diseases. Microorganisms are a heterogeneous group of several distinct classes of living. They constitute the basis for the formal description of taxa, from species and subspecies up to genus and family. Recent advances in biochemical and electron microscopic techniques, as well as in testing that investigates the genetic relatedness among species, have redefined previously established taxonomic relationships and have fortified support for a five-kingdom classification of living organisms. The current classification of Bacteria and Archaea is based on an operational-based model, the so-called polyphasic approach, comprised of phenotypic, chemotaxonomic and genotypic data, as well as phylogenetic information. 1. Parasexuality 5. A classification of living organisms. 3. The Adobe Flash plugin is needed to view this content. Example: -Pseudomonas. There are approximately 400,000 types of fungi. Groups of pupils develop a poster with good and bad aspects of their microbe to answer the question: hero or villain. Once upon a time biologist only recognized two kingdoms: Plant and Animal (this was how organisms were classified when I was an undergraduate). Whole Parasitology covers mainly Parasites, Host and its association between them.For having a very clear cut knowledge about Introduction and Classification of Parasites … Bacteria: Classification Nutrition Recombination PPT Presentation Summary : An accumulation of nutrients (nitrates and phosphates) can lead to an overgrowth of cyanobacteria known as eutrophication or population/algal bloom. Introduction to bacteria, viruses and fungi. It's a field in which bacteriologists study and learn more about the various characteristics (structure, genetics, biochemistry and ecology etc) of bacteria as well as the mechanism through which they cause diseases in humans and animals. In biology, the field of taxonomy is tasked with describing, naming, and classifying organisms; the latter according to some metrics of similarity. Introduction The purpose of this lecture is to introduce you to terminology used in microbiology.

Classification on the basis of temperature response: - Bacteria can be classified into four major types on the basis of their temperatures response as indicated below: - i) Psychrophilic bacteria:-These type of bacteria grows just above the freezing temperature, they can cause contamination of food stored in the refrigerator. Gram-positive and gram-negative bacteria are classified based on their ability to hold the gram stain. Meaning and Characters of Cyanobacteria: The cyanobacteria (the earlier blue-green algae), or the blue-green bacteria, represent a group of photosynthetic, mostly photolysis-mediated oxygen-evolving monerans (prokaryotes).

One advantage of the stained bacteria smear slide over hanging drop slide is bacteria is more visible strained bacteria smear are useful in helping to classify and identify bacteria. 5. A. Aristotle is credited with the first true classification system. Spiral bacteria include the small gastrointestinal pathogen Helicobacter that colonizes the stomach, leading to gastric and duodenal ulcers and gastric cancer, and Campylobacter spp. Classification seeks to describe the diversity of bacterial species by naming and grouping organisms based on similarities.

Due to the presence of chlorophyll like pigment they perform photosynthesis. Microorganisms can be classified on the basis of cell structure, cellular metabolism, or on differences in cell components such as DNA, fatty acids, pigments, antigens, and quinones. Bacteria are classified and identified to distinguish one organism from another and to group similar organisms by criteria of interest to microbiologists or other scientists.

Classification of bacteria based on nutrition requirements. 4. that cause acute diarrhoea (see Vibrio, Campylobacter and Helicobacter). Introducing 3 types of microbe with fact sheets and a wanted poster. classification: the act of forming into a class or classes; a distribution into groups, as classes, orders, families, etc., according to some common relations or attributes. AN INTRODUCTION TO TAXONOMY: THE BACTERIA CHAPTER 9 Taxonomy Definition Binomial Nomenclature Strains Classification Hierarchy Tools of Taxonomy Dichotomous keys 5 Kingdom Classification Whittaker Kingdom Monera Kingdom Monera Archaeans Kingdom Protista Kingdom Fungi Kingdom Fungi Kingdom Plantae Kingdom Animalia 3 Domain Classification Bacteria Archaea … Fungi are widely distributed in nature (air, water, soil, decaying organic debris). The category ‘Microbes’ includes a massive range of organisms including bacteria, fungi, viruses, algae, archaea and protozoa. Describe the different types of bacteria 3. Classification of Bacteria of Medical Importance that give Gram-negative Reaction This classification was carried out in 1986 and placed spirochetes, spiral and curved, aerobic bacteria and facultatively aerobic rods, obligate anaerobic bacteria, aerobic and anaerobic cocci, sulfate and sulfur-reducing, rickettsias, clamydias, and mycoplasmas in this group. 17 th century description of taxa, from species and subspecies up to genus and family and topic.
