I think that using too much antibiotics is not a good idea.

I noticed the bacteria Salmonella, C. defficile, and C. jejuni are hurtful to humans.

I noticed that Patient 23 had C. jejuni in their stomach when they were sick.

This matters because L. reuteri can be a very helpful bacteria.

I think using fecal transplant can cure a lot of people's illnesses.

I think bacteria can be hurtful to the human microbiome.

This matters because Patient 23 was feeling healthy again.

I noticed on week 9, after a fecal transplant, Patient 23's gut bacteria was the same as week 1.

This matters because the antibiotics kill good and bad bacteria.

I noticed there was a lot of open space in Patient 23's gut microbiome after taking antibiotics.

I think bacteria can be helpful to the human microbiome.

I saw that C. difficile only was in Patient 23's gut in week 7, after antibiotics.

This matters because C. difficile is harmful to the body.

I think bacteria can be helpful and hurtful to the human microbiome.

This matters because Patient 23 was feeling well during week 1 and week 9.

I noticed more good bacteria like L. reuter, B. fragilis, and B. animalis in Patient 23's gut during week 1 and 9.

This matters because we want good bacteria to take up the space in our microbiome.

I read that L. reuteri, B. animalis, B. fragilis, and E. coli can be helpful to the human body.
