Infectious keratoconjunctivitis in semi-domesticated Eurasian tundra reindeer (Rangifer tarandus tarandus): microbiological study of clinically affected and unaffected animals with special reference to cervid herpesvirus 2

Table 2 Semi-domesticated reindeer screened by ELISA (n = 202) for antibodies against alphaherpes-, gammaherpes- and pestivirus

	Ocular clinical signs ^a
	0	1	2	Not registered
Alphaherpesvirus	29 / 89 (32.6)	7 / 24 (29.2)	16 / 27 (59.3)	10 / 62 (16.1)
Gammaherpesvirus	3 / 89 (3.4)	2 / 24 (8.3)	2 / 27 (7.4)	1 / 62 (1.6)
Pestivirus	7 / 86^b (8.1)	4 / 24 (16.7)	1 / 27 (3.7)	3 / 59^b (5.1)
Gammaherpesvirus and Alphaherpesvirus	1 / 3	1 / 2	2 / 2	0 / 1
Pestivirus and Alphaherpesvirus	6 / 7	4 / 4	0 / 1	0 / 3

Results are presented as positive/screened (%). No individuals were seropositive for both gammaherpes- and pestivirus, nor for the combination of all the three viruses
^aThe severity of the ocular disease was scored with 0 for asymptomatic animals, 1 for animals with increased lacrimation and/or mild conjunctivitis or 2 for animals with moderate to severe clinical signs of IKC
^bThree samples were considered doubtful and run twice with the same result and therefore excluded from the analysis
