Results of PPR experimental infection on goats according five severity criteria

Group	Animal	Mortality score	Clinical score	Tissue virus load score	Hyperthermia duration (days)	Swabs virus load score	Severity score
I	1	2	13	2.2	6	1.6	82.2
	2	1	15	2.8	8	2	91.4
II	3	2	14	2.7	9	1.9	94
	4	3	17	3.7	7	2.3	110.4

Group I was infected by cell virus suspension with a titer of 6.2 logTCID50/ml. Group II was infected by infectious mashed tissue (lung and mesenteric node). both from the same isolate. For each individual goat. a severity score was calculated. We evaluated five criteria by significance: 1) Mortality. 2); Clinical scoring; 3) Viral load in post mortem tissue; 4) Hyperthermia duration; 5) Viral load in swabs (number of positive and cycle threshold (Ct) values). Each criteria has a coefficient of significance (5 point for criteria 1 to 1 point for criteria 5). The severity score is a cumulative value of each criteria score. Previously multiplied by the coefficient of significance
