Clostridia and Bacillus By lec DrThanaa Rasheed 7 th Lec Bacteriology GramPositive Rods There are four medically important genera of grampositive rods Clostridium Bacillus . Clostridium , a Gram-positive spore bearing anaerobic bacteria is the major aetiological agent of diarrhoea and colitis associated with antibiotics.

These bacilli are ubiquitous, and because they form spores they can survive in the environment for many years. . powerfull. exotoxins . some species are . saccharolytic. , producing acid and gas from carbohydrates and many are . proteolytic. , the clostridia are widely distributed in nature and are present in soil and in the intestinal tract of man and animals . . . . . . Dr.oruba. Khalid abbas. ACTINOMYCETES. In this lecture , we shall discuss 3 genera of actinomycetes: . Actinomyces, Nocardia. , and . Streptomyces.. . These organisms have been shown to be . 1. Demonstrate a basic understanding of commonly encountered organisms in the healthcare setting.. Discuss the importance of reviewing and interpreting Microbiology lab results.. Give examples of pathogenic vs. non-pathogenic bacteria.. 1078 1079 separated into two tubes; one tube contained anticoagulant for hematology studies, and in other tube without anticoagulant was used for serum separation and subsequent biochemical tests. Blo True or False. False - the presence of microbes in a clinical specimen does not always indicate the presence of infection.  Prokaryotic cell structure is microscopically characterized by:. A.
