What is the Unknown Bacteria with Unique Characteristics?

AI Thread Summary
The discussion centers around identifying a specific bacterium characterized by several key traits: it is catalase positive, oxidase positive, ferments glucose while producing gas, is a gram-positive facultative anaerobe, highly antibiotic-resistant, and motile. The bacterium can grow at temperatures up to 103°F, with colonies that are initially white, turning yellowish-orange after 2-3 days, exhibiting small punctiform growth with raised elevation and variable margins. The odor is described as pungent, with an ammonia scent developing over time. Participants suggest consulting the CDC's pathogen identification service for assistance and emphasize the importance of the sampling location, as well as the need for precise measurements of the bacterial rods. The discussion highlights the complexity of bacterial identification and the necessity for thorough investigation and consultation of reliable databases.

@Xinna -

Good, well written question. I do not know of any regular posters here who could help. Is this some kind of of assignment or is it part of your work?
The CDC has a pathogen identification service. Hospitals often refer this kind of problem to them.

In order to not destroy christmas for all of us! Please don't forget post your findings here if you find the answer elsewhere.

I like the question but couldn't guess. I suppose you would need to consult som serious database.

Another clue to be used for "common things" is WHERE you sampled or found these initially? In a human or elsewhere?

And are all characteristics conifdent enough?

I coulnt see the scale. How many um are the rods?

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
