Griffith used two strains of pneumococcus ( Streptococcus pneumoniae ) bacteria which infect mice a type III S (smooth) and type II R (rough) strain.

It is inactive in vitro to most strains of Pseudomonas aeruginosa and many strains of Enterobacter cloacae.

The pathogens exploiting this endocytic pathway include viruses such as SV40 and polyoma virus and bacteria such as some strains of Escherichia coli , Pseudomonas aeruginosa and Porphyromonas gingivalis .

Therapy resistant strains of pathogens are appearing.

We were happy to see that, although our three strains had been previously identified bacteria, two of them were not previously associated with phthalate degradation, so this was actually a novel discovery.

These bacteria prokaryotes have been designated as Diderm Bacteria.

That's a lot of bacteria.

It strains me past the compass of my wits

Now that we grew the bacteria, we wanted to isolate strains by streaking onto mediate plates, because we thought that would be less accident prone, but we were wrong again.

The tester strains also carry mutations in the genes responsible for lipopolysaccharide synthesis, making the cell wall of the bacteria more permeable, and in the excision repair system to make the test more sensitive.

Regrowth of bacteria Once removed from sunlight, remaining bacteria may again reproduce in the dark.

These strains express themselves on policy issues.

Some of these bacteria are resistant.

Bacteria are everywhere.

That's 100,000,000,000,000 bacteria.

The bad bacteria...

They're bacteria, so...

In addition, wild aquatic birds carry all known strains of influenza.

Now, you have two camps of bacteria.

Some bacteria figured out how to stay away from penicillin, and it went around sort of creating its little DNA information with other bacteria, and now we have a lot of bacteria that are resistant to penicillin, because bacteria communicate.

We genetically engineer bacteria.

Pasteur experimented with bacteria.

Bacteria are microscopic organisms.

I collaborate with bacteria.

Hey, these are bacteria.

And it's killing bacteria.

The most stupid bacteria.

Other notable groups of gram negative bacteria include the cyanobacteria, spirochaetes, green sulfur, and green non sulfur bacteria.

The genomes of two different A. niger strains have been fully sequenced.

And all different strains are colored in different colors.

Our mushroom strains were in the highly active range.

Verrucomicrobia is a recently described phylum of bacteria.

90 of them are from bacteria and fungi.

We need to be less afraid of bacteria.

Really only two things, bacteria are going to be prokaryotic and the the archaea bacteria,

So this represent this would be just a few little bacteria here, many, many bacteria...

And bacteria may be gambling.

Not even bacteria. My God.

Bacteria and microorganisms are everywhere.

How does nature repel bacteria?

So, these are bad bacteria.

Attack Bacteria at once! But...

Bacteria are incredibly multi drug resistant right now, and that's because all of the antibiotics that we use kill bacteria.

The room is filled with the quiet, yet lively, strains of Malagasy songs.

Some strains are also found in the cocoons of the earthworm Eisenia fetida .
