[RC] Leptospirosis Links - Linda MarinsHere are my leptospirosis links. Sorry it took so long; I've changed ISPs. ===================================================== Here are the Leptospirosis links I found most useful. A lot of these are 90% redundant with the information in other links, but I saved them anyway because they contained some fact not stated in the others. ---------------------------------------------------------------- NOTE ON TERMINOLOGY See http://en.wikipedia.org for explanations of "IgG" "IgM," "ELISA" etc. ---------------------------------------------------------------- World Health Organization This really is the best detailed up-to-date technical, but-not-too-technical, source I found. It has a lot about animal lepto because animal lepto is so totally bound up with transmission to humans. Best source on serovars, proper titre technique, and sanitary procedures. http://whqlibdoc.who.int/hq/2003/WHO_CDS_CSR_EPH_2002.23.pdf ---------------------------------------------------------------- University of Kentucky Gluck Equine Research Center, Lexington Various past issues of Gluck's "Equine Disease Quarterly." July 1994--Count of lepto-induced foal abortions (1.2 meg .pdf) See: http://www.ca.uky.edu/gluck/q/Q_issues.htm July 1995--Count of lepto-induced foal abortions. Also includes a summary history of the recent realization that leptospirosis is a frequent culprit in equine reproductive failures. (2.9 meg .pdf) See: http://www.ca.uky.edu/gluck/q/Q_issues.htm http://www.ca.uky.edu/gluck/q/1997/july97/Q_jul97.htm July 1997--Wildlife populations increasing, creating possible increase in diseases they carry, like lepto Also, count of foal deaths due to lepto. http://www.ca.uky.edu/gluck/q/1997/july97/Q_jul97.htm Oct 1999--Ditto. http://www.ca.uky.edu/gluck/q/1999/oct99/q_oct99.htm April 2001--Ditto. http://www.ca.uky.edu/gluck/q/2001/apr01/q_main.htm April 2004--Ditto. http://www.ca.uky.edu/gluck/q/2004/apr04/q_apr04.htm January 2005--Search for equine lepto vaccine, report on research in progress. Brief hint why current bovine/canine vaccines don't have enough of the right things in them. http://www.ca.uky.edu/gluck/q/2005/jan05/q_jan05.htm UKY_Paper_2004.ppt -- 4.6 meg. Powerpoint slide presentation on diagnosing foal death due to lepto. I don't have a link to where I found this, but will send the .ppt file to you if you're interested enough. ----------------------------------------------------------------------- Report from the 8th International Conference on Equine Infectious Diseases, November, 1998 http://www.neosoft.com/~iaep/pages/edwatch/leptospirosis.html Good short, dense statement of current view of problem and avenues for research. ----------------------------------------------------------------------- UC Davis http://www.equusite.com/articles/health/healthUveitis.shtml Lepto identified as source of moon blindness (recurrent uveitis). Press release, 2000, summarizing: Ref: RB LeFebvre, NA Faber, JE. Madigan and NC Buyukmichi Recurrent uveitis (moon blindness) in horses and its relationship to leptospiral infection (97-02) The 1999 Research Report, UC Davis Center for Equine Health. http://faculty.vetmed.ucdavis.edu/faculty/eratwill/ http://www.epi.ucdavis.edu/F-atwillr.htm Bio and profile of UC Davis Ag Extension Veterinarian Rob Atwill who studies infectious diseases in animals, including wildlife and horses. This is the fellow who did the study on cryptosporidium in horses cited by Envirohorse. ----------------------------------------------------------------------- Stanford University--School of Medicine http://med.stanford.edu/profiles/frdActionServlet?choiceId=showPublication&pubid=33138&fid=4603 Lepto on the rise in California (abstract of 2004 paper in the journal of Emerging Infectious Diseases) "From 1982 to 2001, most reported California cases occurred in previously healthy young adult white men after recreational exposures to contaminated freshwater." Lucy Tompkins, coauthor. ----------------------------------------------------------------------- Merck Veterinary Manual http://www.merckvetmanual.com/mvm/htm/bc/30300.htm Description of equine recurrent uveitis. http://www.merckvetmanual.com/mvm/htm/bc/51204.htm Lepto in Horses http://www.merckvetmanual.com/mvm/htm/bc/51202.htm Lepto in Cattle ----------------------------------------------------------------------- Cornell University http://web.vet.cornell.edu/public/research/zweig/changlepto01.html Bio of Vet Prof Chang researching lepto vaccine for horses Student Notes: http://cvmstudent.cvm.msu.edu/cvm2008/vet%20reference/equine_leptospirosis.htm http://cvmstudent.cvm.msu.edu/cvm2008/vet%20reference/leptospira.htm http://cvmstudent.cvm.msu.edu/cvm2008/vet%20reference/bovine_leptospirosis.htm http://cvmstudent.cvm.msu.edu/cvm2008/vet%20reference/leptospirosis_in_humans.htm ----------------------------------------------------------------------- Ban Dogs from California Trails Because They Spread Lepto http://tchester.org/srp/lists/dogs.html At least one person has tried to get dogs banned from trails in California by arguing that they spread leptospirosis. I copied this (and other reports on lepto in wildlife) in case somebody starts making the same kinds of arguments to ban horses from trails to protect the water supply, by claiming horses spread lepto. Lots of hikers hike with their dogs (it is the most popular single recreation in my local park's multi-use trail system) and I figured if they tried to ban horses for lepto, I'd point out that the exact same argument can (and has been) made to ban the park commissioners from walking their own dogs! Lepto in Dogs http://www.labbies.com/lepto.htm Lepto in dogs. Mentions the shift from one set of serovars for which the canine vaccine is effective to a different set of serovars (including L. pomona) for which it is much less effective. L. pomona is the big culprit in horses. The same problem exists for trying to use bovine vaccine for horses. Also mentions that vaccine probably won't protect for even a whole year! Has good references, including a link to a "Leptospirosis Links Page" that I haven't visited yet (canine orientation.) http://www.dnet.net/personal/cottrell/leptosp.htm Lepto in Coyotes http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11310882&dopt=Abstract Coyotes have moved onto my brother-in-law's east Tennessee farm. I've seen their scat in my barn. Maybe they are spreading it instead of the raccoons. ----------------------------------------------------------------------- Ontario, Canada Dept. of Agriculture Fact Sheet on Lepto http://www.omafra.gov.on.ca/english/livestock/horses/facts/00-065.htm ----------------------------------------------------------------------- Michigan Dept. of Natural Resources Fact Sheet on Lepto (similar to Ontario paper, above). http://www.michigan.gov/dnr/0,1687,7-153-10370_12150_12220-26943--,00.html (I'm not sure this link is still working.) ----------------------------------------------------------------------- http://www.igs.net/~vkirkwoodhp/eru.htm Equine Recurrent Uveitis--Information for the Horse Owner Non-technical summary paper by Mary G. Nelson with references to other sources. Kind of out-of-date: most recent reference is 1993 and most are *older*. Also tends to get alternative medicine-y. This lady also has a whole web page for horse owners trying to cope with this: www.erunetwork.com ----------------------------------------------------------------------- Diagnostic Automation, Incorporated Calabasas, California http://www.rapidtest.com MSWord file describing a test sold commercially to laboratories for performing Serum ELISA tests for Leptospira IgM. Good for insight into just what performing a titre test actually involves, and how easily it can go wrong!
