Zoonotic Diseases

Diseases discussed here have a history of use as an agent for biological warfare, either in the U.S. or abroad. Its use may have been experimental or actual, and any detrimental consequences upon humans, animals or the environment may have been intentional or not, depending on the circumstances, the point in time, and the nature of the disease.

A new highly pathogenic strain of virus PRRS has been detected


Researchers at the University of Ghent (Belgium), led by Dr Hans Nauwynck,

have discovered a new strain of the porcine reproductive and respiratory

syndrome virus (PRRSV).

PRRSV is divided into genotypes of Europe and of North America. PRRSV

isolates from Eastern Europe belong to the European genotype, but are

different subtypes.

The researchers found, in a pig farm in Belarus, a new PRRSV which they

named "Lena". Analyses revealed that Lena is a new subtype 3 in Eastern

Europe, highly pathogenic and causes severe clinical symptoms. It is

different from European subtype 1 Lelystad and North American US5 strains.

[The original paper, published on 4 Jun 2010 in BMC Veterinary Research (an

open access, peer-reviewed journal, UK) is available online at

(ref 1). The paper includes,

among other data, a description of the severe clinical signs, including

significant mortality, in pigs experimentally infected by the "Lena"

strain, compared with other Type I (European) PRRSV.

Most ProMED-mail's postings addressing PRRSV, so far, were related to the

major epizootic (popularly named "blue-ear disease") in China and Vietnam

since 2006. This was caused by a Type II virus, related to North American

lineages. A list of available vaccines against PRRSV is to be found at
