Table 1 Clinical outcome of the pigs following viral challenge.

From: Experimental infection of Bama miniature pigs with a highly virulent classical swine fever virus

Groups No. of animals with fever (≥ 40.5°C) No. of days to fever onset Fever frequency during the trial Survival rates

  1. Twenty specific-pathogen-free Bama miniature pigs were randomly divided into five groups. Groups A, B and C (n = 5) were inoculated i.m. with 104, 105 and 106 TCID50 CSFV Shimen strain, respectively. Three non-inoculated pigs were housed in the same pen and served as in-contact animals. Two uninfected control pigs were housed in a separate pen. Clinical outcome, fever frequency and survival rates after viral challenge were calculated.
