  • Anthrax.
  • Diphtheria.
  • Enterococcal infections.

What are examples of Gram positive rods?

INTRODUCTION. There are five medically important genera of gram-positive rods: Bacillus, Clostridium, Corynebacterium, Listeria, and Gardnerella. Bacillus and Clostridium form spores, whereas Corynebacterium, Listeria, and Gardnerella do not.

Which is not Gram positive bacteria?

Some Firmicute species are not gram-positive. These belong to the class Mollicutes (alternatively considered a class of the phylum Tenericutes), which lack peptidoglycan (gram-indeterminate), and the class Negativicutes, which includes Selenomonas and stain gram-negative. Additionally, a number of bacterial taxa (viz.

What is E coli metabolism?

Central Metabolism. Escherichia coli is a facultative anaerobic, Gram-negative organism and capable of using a wide spectrum of organic carbon sources for heterotrophic growth. The availability of electron acceptors triggers the strategies used for energy production – respiration or fermentation.

What media would be used to identify e coli?

Choose your type of bacterial growth media:

LB Broth and LB Agar Most referenced bacterial media for growth and maintenance of recombinant E. coli strains
M9 Minimal Commonly used bacterial media for cultivation and maintenance of E. coli strains.

What are the three main types of microbiological culture media?

These are classified into six types: (1) Basal media, (2) Enriched media, (3) Selective (4) Indicator media, (5) Transport media, and (6) Storage media. 1. BASAL MEDIA. Basal media are those that may be used for growth (culture) of bacteria that do not need enrichment of the media.
