A prospective study on insect bite hypersensitivity in horses exported from Iceland into Switzerland

Table 1 Sulfidoleukotriene (sLT) production by peripheral blood leucocytes (PBL) from horses remaining in Iceland in areas with low or high infestation with Simulium vittatum

Incubation of PBL with	Median (range) of sLT released (pg/mL) from PBL of horses coming from areas with		Low versus high P
Incubation of PBL with	Low Simulium (N = 53)	High Simulium (N = 75)	(MWU-test^d)
Cul2	68 (0–925)^a	74 (0–164)	Ns
Sim10	6 (0–408)^b	7 (0–391)^c	Ns

PBL were stimulated with C. nubeculosus extract (Cul2: 2 μg/mL) or S. vittatum extract (Sim10: 10 μg/mL)
The cut off values defined in Baselgia et al. [4] were used
Ns not significant
^aOne horse above cut off (310 pg/mL)
^{b, c}Two horses in each group above cut off (200 pg/mL)
^dMann–Whitney U test
