Natural History of Porcine Circovirus Type 2


Yesterday, we saw the publication, in the UK, of an article covering two of the main issues we have explored here and on the newsgroup uk.business.agriculture over the past 13 years:

the importance of mutated circovirus and the import of pig disease in live movements.

Two subjects were hitherto more or less barred from open discussion in Britain, obviously because of their fundamental significance to the source of the disastrous CSF and FMD epidemics in 2000- 2001 and - even worse - the spread of antibiotic resistance.

This marks a major milestone in the unraveling of a series of purely British cover-ups and scandals, but which carry a deep significance to human health worldwide.

As usual, just a few extracts to illustrate the nature of the content and mark the publication, do read in full here

Natural History of Porcine Circovirus Type 2

02 September 2013

SPAIN - A review published recently by researchers from the Research Centre for Animal Health (CReSA) summarizes current knowledge on the natural history of infection with porcine circovirus type 2 (PCV2) and
related diseases.

The perception of the importance of such pathogenic PCV2 has changed dramatically in the last 15 years.

The ubiquitous nature of the virus, retrospective evidence of this infection long before the disease association (PMWS or PCV2-associated systemic disease)...

...this virus is now considered an important pig pathogen...

...The emergence of the PMWS epidemic as a problem in the late 90s or mid-2000 could be related to a number of known and unknown variables.

Based on available data, international trade of pigs may have played an important role in the dissemination of sensitive pig genetic lines, as well as replacing the PCV2 genotype worldwide (PCV2b on PCV2) during this period.
