Values are means ± s.d.; N=5-6 isolations.

State 3 values of winter animals were significantly lower at both temperatures than in summer animals at 10°C (P<0.05); state 4 and 4+ values at both temperatures differ significantly from state 3(P<0.001) and with season (P<0.01) as well as between temperatures (P<0.001); ANOVA; Newman-Keuls test).
