OK I am officially completely confused. When one talks about Lepto in cattle and one talks about the 5 way vaccine or the 5 strains one is usually talking about Lepto (serovars) hardjo, pomona, icterohaemorrhagiae, grippotyphosa and canicola.
One is not talking about the serovar Lepto hardjo bovis. The bovine is the reservoir of infection by the serovar Lepto hardjo bovis and the bacteria reside in the kidneys and are shed in the urine and semen. When one talks about Spirovac one is talking about vaccination for Lepto hardjo bovis (https://animalhealth.pfizer.com/sites/pahweb/US/EN/Products/Pages/SPIROVAC%C2%AE.aspx) not the other 5 strains of Lepto that can infect cattle.
So this bull does not have the 5 strains of Lepto - testing of which is required for CCS certification http://www.naab-css.org/about_css/Participation2011.htm - but according to jagerbeef when he called ABS he was told the semen went back because the bull had Lepto and his vet said to Spirovac his cows ........is it clear as mud to anyone?
So is this Lepto hardjo bovis NOT a strain that is tested for when semen needs to meet Canadian requirements? If not, why isn't it?
