This organism is sometimes found in dog urine and urine is the best body fluid to identify this,which is it? (hint its biphasic)

REAL LIFE SCENARIO: When I was at work tonight some doctor from the medical school that sends us their micro specimens (probably one of those darned residents :-)) wanted two blood cultures to be watched for Leptospira. Spirochetes are extremely fastidious and I wasn't sure if the blood culture medium would grow it or not. I checked with our Ph.D. microbiologist, and I was informed that it would not.
Doc's options at that point were to order antibody levels (IgM/IgG) via a blood test (sendout - wait for results for awhile), or send a urine and/or blood specimen for dark field examination. I have never performed a dark field but it is still possible IF you communicate with the lab ahead of time. Our Ph.D. said he would perform the exam tomorrow IF they got him a specimen right away during the day shift. I've also noticed that these weird requests ALWAYS happen on weekend evenings. What happens on the floors on the weekends that prompts these orders?
So, all you docs out there: if you're suspecting this organism, blood cultures are NOT the way to go. Always check with the lab first. :-)
