A classification of living organisms. that cause acute diarrhoea (see Vibrio, Campylobacter and Helicobacter). The classification of bacteria serves a variety of different functions. 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. Posted March 25, 2014. Groups of pupils develop a poster with good and bad aspects of their microbe to answer the question: hero or villain. Example: -Pseudomonas. Share Share. Classification seeks to describe the diversity of bacterial species by naming and grouping organisms based on similarities. Gram-positive and gram-negative bacteria are classified based on their ability to hold the gram stain. View and Download PowerPoint Presentations on Bacteria Classification PPT. The gram-negative bacteria are stained by a counterstain such as safranin, and they are de-stained because of the alcohol wash. ♦ Autotrophs: These are bacteria which prepare their own food. Parasexuality 5. 2. 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. Van Leeuwenhoek’s observation of microscopic organisms launched centuries of classification based on morphology and physiology . ii) 1. It is the infective agent of Diphtheria, a highly fatal disease in which one in every ten infected died before the DTaP vaccine was created. 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. The Taxonomic Hierarchy. Created: Jan 3, 2013 | Updated: Oct 29, 2014. 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. Gram-negative bacteria are more resistant against antibodies because their cell wall is impenetrable. They can be observed by making hanging drop slide. Classification of Cyanobacteria 3. By. Example: -Pseudomonas. Spiral bacteria include the small gastrointestinal pathogen Helicobacter that colonizes the stomach, leading to gastric and duodenal ulcers and gastric cancer, and Campylobacter spp. This bacteria is a gram positive, club-shaped, non-motile bacteria. – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 6fbfab-ZGU2Y 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.

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. 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.

Because of this variety, bacteria may be grouped using many different typing schemes. Mycology can simply be defined as the study of fungi. 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. The word mycology is derived from the word ‘mykos’ meaning fungus. Fungi are widely distributed in nature (air, water, soil, decaying organic debris).

Microorganisms: An introduction . Different from parasites and fungi (eukaryotic) •Prokaryotic organisms –simple unicellular organisms –no nuclear membrane –no mitochondria –no Golgi bodies –no endoplastic reticulum •Complex cell wall –Gram-positive –Gram-negative. Heterocyst 6. Parasitology is the branch of Science which mainly deals about all the Parasites and its infectious diseases. 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. What does our current evidence tell us about the evolution of prokaryotes and eukaryotes? In News & Views 0. The traditional phenotypic tests are commonly used in actinobacterial identification.
