E. Coli codes for around how many proteins?
Will i find Bacterial spores with Gram negative species?
Will i find Bacterial spores with Gram positive species?
what substance is specific and unique to spore production?
Tell me about Clostridium difficile
Often found in hospitals
spore production in G.I.
what surrounds a spore
Does staph form spores?
Who and when observed that pneumococcus virulence was related to presence of a surrounding capsule
Define competent cells
naturally capable of taking up exogenous DNA, usually toward end of logarithmic growth
Name some bacteria than are commonly known to conjugate
how are antibiotic resistance in gram positive bacteria streptococci and clostridia brought together?
adhesion molecule, not sex pili
What are ways we can classify viruses
Means of replication
Tissue or Organ (tropism)
Are most DNA viruses single or double stranded? What is an exception?
Most are double stranded
Parvo virus is single stranded
What family does influenza come from?

What is a virion what does it consist of?
Virus particle which consists of
genome and capsid
What is the genome of the species?
DNA or RNA of the virus, never both
What is the capsid
Protein layer surrounding genome
what is an envelope?
membrane composed of lipids, proteins, and glycoproteins.
Is a capsid a rigid structure?
Damn right it is.
What are naked capsids usually resistant to?
Enveloped or viruses with naked capsids must remain wet?
What type of virus is better suited for the G.I. tract?
eclipse period ends with
assembly of new virions
