Any bio experts out there? ( bacterium)

Well now, that isn't humans ingesting antibiotics. That's organisms presumably acquiring resistance due to overuse of antibiotics in the cattle, then being transmitted to man. Very poor practice could result in this.

If regulations are tight enough, and enforced, humans do not ingest antibiotics even if they are fed to the meat animals. Doesn't happen in this country. As I said, your mileage may vary.

I still think it's a brain-dead idea though.

My curiosity is about the earlier subject- We have all read the scare stories about rising incidence of human MRSA in hospitals.
Is there an analogous increased incidence among factory farmed, antibiotic fed animals of MRSA (or of it's analogues) in open wounds? (I realise a barn is not a hospital and the animals therein should be generally healthy, but I looked at cattle in a barn on Saturday- at least one in ten had minor open wounds , from scratching presumably. The beasts were mostly in contact with one another.
(They had a yard outside but seemed reluctant to move.)
 
Wow Soap's got a point , surprised I didn't pick up on it sooner.
What you were saying about the animal infections is the pathogen may be harmless to the dog , but she could be a typhoid Mary for humans?
 
Two in one. Antibiotic resistance patterns vary, but there isn't anything really comparable to MRSA in veterinary medicine. Because we don't have the sort of hot-house environment created by human hospitals. It's not the concentration of people, it's the concentration of sick people.

The most annoying thing is Pseudomonas aeruginosa which tends to be resistant to most of the usual stuff, but it's more of a nuisance than lethal, and as it's usually superficial (in ears) then topical antiseptics can also be used. Just don't tell Steve Dean.

No, so far as I know, neither Staph epidermidis or Staph intermedius is a particular problem in man. They're just closely related organisms that seem to have a preference for dogs. And they're not especially resistant usually. Remember, most humans are harbouring Staph aureus, just not MRSA.

Non-expert's curiosity: did resistance to a particular antibiotic arise once and spread, or can s. aureus evolve resistance in many hospitals?

Are there cases of "nuisances" evolving into something more serious, or are most serious diseases either old or made the jump from other species?

Jesus are you p-sycic or something?
My sister -and I am not BSing You- is flying to the Mayo on Tuesday of next week because of a Pseudomonas A infection (colonization ? ) that has caused Pulmonary damage. She is on Cipro now and the maintenance dose seems to have stabilized her condition. Her background is in physiology and nutrition but she now is a personal trainer and runs classes at the local Health club. Seems the steroids she was taking after a bout on Pneumonia was masking the symptoms. No known cause of infection she doesn't swim in ponds or lakes . She is a very healthy individual with no immune problems. ( sept she's a dumb ass and didn't let herself heal after the original infection ). I suspect that she acquired it at the health club thru under treated whirlpool water or something along those lines. I find it hard to be clinically detached as I adore the woman , but I am curious and I can PM You with the outcome if your interested.

I'm gratified to have learned so much in one day.

Back to My original question tho.Prester, Rolfe, others? Is there a way to access the PBP2a protein directly?

Ow! Lungs are not a great place to get that bug. Still, they'll have done sensitivity tests and ciprofloxacin is a good antibiotic, and in an otherwise healthy patient the immune system should be able to cope.

You're right, it's a water organism, and a jacuzzi or something like that might be a source. I do hope she's OK, let me (or all of us) know how she gets on.

Your basic question is outside my area of competence, but Prester John's the expert.

PS. Silly story. I was in the witness box as expert witness for the prosecution on a cruelty case. Among other things the dog had a bad ear infection. I remarked that from the smell it was a fair guess it was Pseudomonas aeruginosa. The defence barrister, who was an arrogant little creep, jumped up and objected that I couldn't say that because I hadn't mentioned it on my statement. I said oh yes I had. (I knew I'd listed the three main organisms cultured, and that was one.) He ran around brandishing my statement demanding to know where it was. When it was pointed out to him he went all red. He'd been looking for a word begining with S....

Thank you for that Rolfe! Funniest thing I've heard in weeks!
