Maternally derived antibodies at the time of porcine circovirus type 2 vaccination: does it matter?

One issue is to overcome maternal immunity, which is true for all PCV2 vaccines in the market, and another is whether the most from these vaccines is achieved independently of the PCV2 antibody titre at vaccination

Sanitary Equilibrium: The role of PCV2 vaccines

The most common problems are due to interference with maternal antibodies and coincidence of vaccination with a recirculation of PRRS: viremic animals.

We may have some highly efficient vaccines, but we shouldn’t forget that for their application we must obtain good diagnostic information, and that in all cases we should not lose sight of good management and a good control of the concomitant diseases.

Risk and/or triggering factors of porcine circovirus

Between 1995 and 1997, at the beginning of an epizootic called “maladie de l’amagrissement du porcelet” (MAP), it was observed that the farms that were most affected and that had the most losses, generally presented obvious deviations from what we would consider to be a suitable management of the animals and facilities. This is why Dr. François Madec made a list of management practices with the aim of improving the anomalous situation observed.

Epidemiolology and control of swine influenza

Considering the current situation we are reproducing an article by Tom Alexander previously published by 3tres3.com on 30/dec/2005. A key factor in the epidemiology of influenza is the ability of the virus to mutate or, when cells are infected by two different strains, to recombine to produce new viruses. Either of these genetic changes results in the repeated appearance of new strains with different immunogenic structures and/or virulence, including their ability to infect different hosts.
