Brucella follow up

I'm pretty sure all of us at the laboratory who were exposed to the Brucella Melitensis are just about home free.  All of the latest serology results came back and our antibody titers were all less than 20 according to the results.  Officially though, we all have two more blood draws/testing sessions to go in order to be cleared.  This will put us all at the 6 month mark, which according to literature and test cases, is the end of the potential incubation period for Brucella.  Past cases have seen those exposed develop Brucella anywhere starting from 5 days and up to 6 months post exposure.  Hopefully, none of us will be added to the literature or become a new test case.
