Pathogen Characteristics

Top of page

The causative agent of PRRS is an enveloped virus of 45-65 nm diameter, with a relatively smooth surface and an isometric, occasionally icosahedral nucleocapsid core of 25-35 nm diameter. Short (8-12 nm) granular projections are sometimes seen on the surface of negatively-stained extracellular viral particles. Three proteins have been detected in purified virions: a nucleocapsid protein (VP1), a matrixprotein (VP2), and a glycosylated envelope protein (VP3). PRRS viruses are sensitive to lipid solvents. They can pass through 200 nm filters with high efficiency and 50 nm filters with low efficiency. PRRSV is sensitive to pH variations away from neutral; the virus is stable at pH 6-7.5 but infectivity is quickly lost above or below this range. The virus is stable for long periods at -70 and -20ºC, but 90% infectivity was lost after storage at 4ºC for a week. Infectivity persists for 1-6 days at 20-21ºC, 3-24 h at 37ºC, and 6-20 min at 56ºC. (Bloemraad et al., 1994).

In the laboratory, PRRSV can be neutralized by convalescent sow or rabbit hyperimmune sera (Benfield et al., 1992) at titres of 1:256 and 1:512, respectively. Cytopathic effects (in cell line CL 2621 or alveolar macrophages) begin as small rounded clumps of cells appearing raised above the uninfected remaining monolayer. Many cells develop pyknotic nuclei and detach from the monolayer within 2-4 days. PRRSV has no serological cross-reaction with other vertebrate RNA viruses. It most closely resembles lactic (lactate) dehydrogenase (elevating) virus (LDV) of mice and simian haemorrhagic fever virus (SHFV).

Disease(s) associated with this pathogen is/are on the list of diseases notifiable to the World Organisation for Animal Health (OIE). The distribution section contains data from OIE's Handistatus database on disease occurrence. Please see the AHPC library for further information from OIE, including the International Animal Health Code and the Manual of Standards for Diagnostic Tests and Vaccines.
