  • Title: Characterization of a parvovirus isolated from a pig fetus.
    Author: Foni E, Gualandi GL, Capucci L.
    Journal: Microbiologica; 1989 Jul; 12(3):277-80. PubMed ID: 2550743.
    Abstract:
    A small hemagglutinating virus belonging to the Parvoviridae Family was isolated from a 70 day-old pig fetus in a breeding herd in which infertility, metritis and abortions were reported. The virus, named 85/193L, was isolated either in primary pig kidney (PK) cells or in a continuous cell line of minipig kidney origin (MPK), both cell cultures actively growing. It produced a typical cytopathic effect (CPE) starting from the 3rd passage and intranuclear inclusions surrounded by a halo were observed in stained preparations. The isolate was completely resistant to ether, chloroform and to pH 3; it was not inactivated after treatment at 56 degrees C for 4 h and at 70 degrees C for 2 h, while it was completely inhibited by the 80 degrees C/30 min temperature. It contained deoxyribonucleic acid (DNA). The highest infectious titer was reached at 96 h post infection. The infectivity and the hemagglutinating activity of the isolated strain were both inhibited by the reference immune serum against NADL-2 pig parvovirus. This further confirmed that the 85/193L isolate belongs to the parvovirus genus.
