Porcine Circovirus - robust, hardy and difficult to kill
An interesting piece from the USA illustrating the significance of porcine circovirus on pig health.
Britain experienced a severe circovirus epidemic immediately before the Classical Swine Fever and, Foot and Mouth epidemics in 2000-2001. Little mention was made of it in the media, at the time, and later attempts were made to re-date it to follow the very serious Foot and Mouth epidemic.
Although today PCV2 is the usual term indicating troublesome circovirus, then its presence was usually indicated by references PMWS or PDNS.
Today we hear that:
"....The virus is robust, hardy and difficult to kill. It lasts a long time and is very different from the PRRS virus. It will be there a long time no matter how hard you try to get rid of it..."
That clearly illustrates the British experience - a nasty persistent virus with co-infections requiring antibiotics and creating all the problems of antibiotic resistance.
