Medical Importance of Bacteria. Bacteria are single-celled microorganisms that lack a nuclear membrane, are metabolically active and divide by binary fission.On this basis, bacteria can be organized into three major groups.

For this lecture you should focus on the major concepts and not on the names of the different bacteria.Classification Systems The classification of bacteria serves a variety of different functions. Because of this. variety, bacteria may be grouped using many different typing schemes. site of action of several antibiotics. 23. After Christian Gram developed the Gram stain in 1884, It is evident that bacteria could be divided into two major groups based on their response to the Gram-stain procedure. Gram-positive bacteria stained purple, Whereas The Bacteria [bktr.i.] (singular: bacterium) are a group of unicellular microorganisms.A major step forward in the study of bacteria was the recognition in 1977 by Carl Woese that archaea have a separate line of evolutionary descent from bacteria. Since they are cell wall-deficient bacteria, there is a major reduction in genetic information needed for cell wall biosynthesis.The three major groups of fungi are: multicellular filamentous moulds.

Name: Date: Life Science Chapter 11 Homework Questions S. six major groups on morphological basis.TRUE BACTERIA CocciCocci These are spherical or oval cells. On the basis of arrangement of individual organisms they can be described as Monococci (Cocci in singles) Monococcus spp. Classification of bacteria. 1.1 introduction. Microorganisms are a heterogeneous group of several distinct classes of living beings.The major characteristics of Bacteria are based on their size, shape and arrangements. Major groups of bacteria. 1. BacteriaKorarcheota:Korarcheota is a phylum under the domain Archae. Thisparticular phylum is said to not belong to the main lineage of theother archaeal group because of their 16S rRNA. Major types of bacteria were traditionally classified by physical features or reactions to different types of staining. The advent of molecular genetics has allowed a more-careful division of the different groups of bacteria. Download Immune responses to bacteria.ppt (631 KB).Two major groups of helper T cells are known as Th1 and Th2 cells. These cell types differ in the types of cytokine they secrete.

BACTERIA (>70 major phyla).1. The phylogenetic tree of life contains many bacterial phyla and groups, including the Proteobacteria, Gram-positive bacteria, Cyanobacteria, Chlamydiae, and Spirochaetes. Some bacterial groups lack typical cell wall structure, i.e Mycobacterium and Nocardia. Gram-positive cell wall structure with lipid mycolic acid (cord factor).58. Major Taxonomic Groups of Bacteria. Bacteria ppt Qs. Prokaryote Eukaryote Evolution.17. What photosynthetic member is in this group? Characteristics of Bacteria.No Major Variation in GIT Evolution of All Animals from Fish to Humans. Bacterial taxonomy is the taxonomy, i.e. the rank-based classification, of bacteria.Informal groups based on Gram staining. Despite there being little agreement on the major subgroups of the Bacteria, Gram staining results were most commonly used as a classification tool. Thus, how the major groups of bacteria emerged from the pre-cellular primordial soup and began to differentiate from each other remains obscure [68]. There are three major types of vegetative spores which arise from specialized cells [7,31,116]. 1. Blastospores- are a product of budding.Most labs try to encourage the growth of one group of organisms over another, whether gram negative bacteria (Enteric bacteria), the Streptococci Adherence of bacteria to body surface is the most important event in the pathogenesis of disease.Bacterial adhesins can be divided into two major groups: pili (fimbriae) and nonpilus adhesins (afimbrial adhesins).

Bacteria, virus, heat, radiation etc. collectively called etiology.Major groups of diseases are Inflammatory, Degenerative Neoplastic. Inflammatory disorders are due to damage to tissues by various injuries (physical, chemical, infections etc.) It is important to acknowledge that the widespread term LAB have no official status in taxonomy and is only a general term of convenience used to describe the group of functionally and genetically related bacteria. LAB consist of bacterial genera within the Firmicutes comprised of about 20 genera. Return to Content. 21 Major Beneficial Activities of Bacteria. Article Shared by.

Bacteriophages or bacterial viruses are viruses that parasitize bacteria.Bacteriophages fall into four major groups based on the genetic material they possess. The term "bacteria" has been variously applied to all prokaryotes, or to a major group of them exclusive of the anaerobic archaebacteria.Bacteria can be divided into two groups (gram-positive and gram-negative) based on differences in cell wall structure as revealed by Gram staining. Enteric pathogen bacteria Enterobacteriaceae Gram negative Exotoxin enterotoxin Endotoxin in cell walls(LPS) Antigens 3 major groups of antigens: Somatic O A free PowerPoint PPT presentation (displayed as a Flash slide show) on - id: 7054fb-MmQ4M.
