Snapshot of Leptospirosis Strains & Vaccine

Most Leptospirosis strains (there are about 200) do not cause disease, and of the seven clinically important strains, only four — L. icterohaemorrhagiae, L. canicola, L. grippotyphosa, and L. pomona serovars — are found in today’s vaccines. So, exposure risk depends upon which serovars of Leptospirosis have been documented to cause clinical leptospirosis in the…

Avoid unnecessary vaccines with titer tests (Part III)

In my last two posts, I discussed the potential side-effects (vaccinosis) of over-vaccinating our pets, and the difference between MLV (modified live) and killed vaccines. I cautioned that dogs and cats with immune-mediated diseases are especially vulnerable to vaccinosis, since over-vaccination places additional stress on their already compromised immune systems and has been linked to…
