    • Section 1 + 2 The Spirochetes AerobicMicroereophilic, Motile,HelicalVibroid,Gram Negative Bacteria Supervisor: Dr. Magda Aly Prepared by Raghdah Malibari 2012 - 2013
    • Section I The Spirochetes
    • Order: Spirochaetales These order include two families: (1)Family : (2) Family : Leptospiraceae, Spirochaetaceae, followed by has 1 genus is Leptospira. 4 genus. -The end is not usually coiled. -The end is usually coiled - Diamino L – ornithine in - Diamino-pimilic in Piptedoglycan Piptedoglycan. -Facultative Anaerobic. -Using A Carbohydrate and Amino acid as a source of Carbon and Energy. -Microareophilic. - Aerobic. -Using fatty acid as a source of carbon and Energy.
    • Family Spirochaetaceae
    • Genus: Spirochaeta Occur in fresh and salt water . Specially with exist (H2S) > usually found in waste water.
    • Genus: Cristospira Have a Crista in different parts of body cell. Exist in abundance in the intestinal tract of snails. Can not grow in pure culture. Cristispira balbiani
    • Genus: Borrelia - Stained by alanin. - Helical irregular. - No flagellate.
    • There are 3 species caused disease for Human, Animal and Birds: Spices Borrelia recurrentis Borrelia hermsii. Borrelia burgdorferi Infection Reservoir Vector Pediculus humanus Replacing fever epidemic Humans ( lousebrone) Replacing Rodents, so Ornithodoros hermsi fever shelled Endemic ticks (Tick- borne) Rodents, Ixodes spp. deer, Lyme Disease domestic pets, hard shelled ticks
    • Genus: Treponema -Regular Helical. - Can not be stained by routine methods. -Aerobic. 4 species causes diseases for human, 1 for Animal : Genus Treponema Species pallidum pndemicum pertenue carateum cuniculi Disease Syphilis Bejel Yaws Pinta Rabbit Syphilis
    • Treponema pallidum -cause disease: Syphilis in human. -Complex sexually transmitted disease that has a highly variable clinical course. -No natural reservoir in the environment, requires living host. - Organism cannot be cultured from clinical specimens
    • Treponema endemicum -Causes non-venereal syphilis known as bejel or endemic syphilis. -Typically spread among children. - Bejel is completely curable with penicillin.
    • Treponema pertenue -Causes disease Yaws. -Non-venereal transmission, transmitted by direct contact. -Untreated disease not as severe as syphilis, but lesions are more persistent. - Treat with penicillin.
    • Treponema caroteum -Causes disease Pinta . -More common in young adults. -Non-venereal, direct contact, disease of skin. - Treat with penicillin
    • Treponema cuniculi -Not pathogenic for humans. - Causes rabbit syphilis.
    • Family Leptospiraceae
    • Genus: Leptospiraceae -After dye the species of this genus apear as Treponema species. - Aerobic. - Some types of this genus are parasitic and others heterotrophy. Leptospira interrogans Leptospirosis Clinical Syndromes:  Mild virus-like syndrome  (Anicteric leptospirosis) Systemic with aseptic meningitis  (Icteric leptospirosis) Overwhelming disease (Weil’s disease)
    • Section II Helical or VibrioidGram –negative BacteriaAerobicMicroaereophilic Motile
    • This section includes 8 genus can distinguish themselves by the following characteristics : (A) Vibrioid or Helical cells. 1- Bacteria NOT associated with human or animal naturally, and do not have a detrimental effect on other bacteria or algae. - Bacteria usually found in fresh water. - Bacteria found in or on the roots of plants or free-living soil. - Bacteria found in marine water. 2- Bacteria associated with human or animal naturally, and do not have a detrimental effect on other bacteria or algae. - Bacteria found in the reproductive organs and the intestinal tract. - Bacteria cause mouse fever (disease affects human by mouse bite) . - Bacteria cause Diphtheria stomatitis in poultry. 3- Bacteria NOT associated with human or animal naturally, and have a detrimental effect on other bacteria or algae. (A) Straight Rods that have Biflagellate at each pole.
    • A.1. Bacteria usually found in fresh water Genus: Aquaspirillium sp. Genus: Spirillum sp. -Bipolar tufts of flagella. -Inhibition occurs at a concentration of 3% NaCl. -Microereophilic. -Can not demolish Carbohydrate. -Many flagellate in the end of cell. -Inhibition occurs at a concentration of 3% NaCl. -Microaereophilic. - Using Succinate as a source of Carbon. + Oxidase Phosphtase + Catalase - Indol - Sulfatase - Casein - Starch - Gelatin - Esculin -
    • A.1. Bacteria found in or on the roots of plants or free-living soil Genus: Azospirillum - Vibrioid cell , Moving in liquid environments by one polar flagellate and in solid environment by side flagellate. - Have the ability to fixing nitrogen under microareophilic conditions - Grows well on Lactate , Succinate , Malate and Pyruvatic. - It can use the fructose and many monosaccharides and not Disaccharides . -Positive oxidase , G + C = 70% - azospirillum biofertilizer
    • A.1. Bacteria found in marine water Genus: Oceanospirillum -Helical cells . - Need sea water or sodium chloride for growth. -Owns a bundle of flagella in both poles or one flagella at each pole. -Aerobic . -It can not demolish carbohydrates.
    • A.2. Bacteria found in the reproductive organs and the intestinal tract Genus: Campylobacter -Vibrioid or Helical cells. - Moving by one flagella at each poles. - Microareophilic. - It can not demolish carbohydrate . -G + C = 30 – 38 % - Have a role in food poisoning.
    • A.2. Bacteria cause mouse fever (disease affects human by mouse bite) . Genus: Spirillum minus - Spirillum, Helical cells . -Have one or more flagellate at each poles. - Can not isolated on industrial nutritional media.
    • A.3 .Bacteria NOT associated with human or animal naturally, and have a detrimental effect on other bacteria or algae. Genus: Vampirovibrio Genus: Bedellovibrio -Vibrioid cells. -Small vibrioid cells . -Moving by one non-envelope flagellate . - occure in soil, salt water , freshwater and sewage. - causing damage to Eukaryotic and alga Chlorella. -This genus does not penetrate host cells. - moving by one envelope flagellate in one polar. - Causing damage to some Gram-negative bacteria. -Aerobic , G + C = 33- 51.5 % - G + C = 50 %
