What Morphology Are Bacteria With Endospores

ENDOSPORES – The Schaeffer – Fulton Stain. These are very resistant structures made by only a few genera of bacteria. The two genera which we will study are: Clostridium is an anaerobic organism that forms spores. Tetanus, botulism, gas gangrene and pseudomembranous colitis are diseases caused by different species in this genus.

By varying the evaporation time, nanopillars initiated from graphite that was scribbled using a pencil onto silicon substrates were optimized to yield a high inactivation of the Gram-negative bacteria.

Endospores are structures made by bacteria for survival purposes. Bacteria turn to endosporea when they undergo stress, such as an increase in heat or lack of nutrients. This process is known as sporulation. Endospores are small, rounded, resting cells that form inside bacteria when conditions become unbearable.

Round bacteria, known as cocci, or coccus for one cell, might also appear oval, elongated or flat on one side. Bacilli, or the singular bacillus, are rod-shaped organisms that can also look so short and thick that they are called coccobacillus.
