It is an opportunistic pathogen. ]]> 2020-03-04 07:15:31 UTC https://padlet.com/srshaffe5/7cf1g36tmtv3/wish/454154205 Phylogenetic Tree srshaffe5 https://padlet.com/srshaffe5/7cf1g36tmtv3/wish/454154206 Neisseria pharyngis is a bacteria that can live in the mucosa of the lungs. It's most distant cousin is Streptococcus pneumoniae which can infect a person when inhaled in the lungs. Similarly its closest cousin, Klebsiella pneumoniae is most commonly associated with pneumonia in alcoholics or diabetic patients. ]]> 2020-03-04 07:15:31 UTC https://padlet.com/srshaffe5/7cf1g36tmtv3/wish/454154206 Taxonomy srshaffe5 https://padlet.com/srshaffe5/7cf1g36tmtv3/wish/454154207

It has been found to cause endocarditis in dogs. ]]> 2020-03-04 07:15:31 UTC https://padlet.com/srshaffe5/7cf1g36tmtv3/wish/454154209 Erysipelothrix tonsillarum srshaffe5 https://padlet.com/srshaffe5/7cf1g36tmtv3/wish/454154210 A common pathogenic bacteria commonly found in domesticated pigs.

It showed that they have a monolateral distribution, which affects the adhering of the bacteria. This bacteria has been showed to results in endocarditis.

There are not many articles specifically on E. tonsillarum. Most articles discuss the genus in general. The most recent article discussed the pathogenicity of E. tonsillarum for pigs. They were immunosuppressed with cyclophosphamide (CY), dexamethasone (DM), or not suppressed at all. They  found that "growth agglutination antibody titres in all pigs remained unchanged," showing that E. tonsillarum are avirulent.

They seem to have minimal research completed on them as they are more specific microbes newly discovered. However, there are articles that relate them back to endocarditis. Looking at the organisms on the phylogenetic tree. They all appear to be respiratory related. I would like to research them further to see when each were discovered and how the microbes relate on that aspect. These microorganisms differ from the Ted Talk as he talks about the benefits. There were not many articles discussing the benefits of these microbes yet.
