## *3.1. Serum Biochemistry*

Table 2 showed the mean ± standard deviation and range (minimum-maximum) of albumin, TP, AST, ALP and GGT concentrations according to the clinical status: exposed animals that not showed cutaneous clinical signs (a) and exposed sheep that presented skin lesions (b). Serum chemistry references values in sheep are shown in Table 2 for each biochemical parameter analyzed (c) [29].

**Table 2.** Serum liver enzymes in sheep with and without cutaneous lesions 6 months after the onset of the facial eczema (FE) outbreak. Different superscripts between columns shown significant differences between the animal groups compared (\* *p* < 0.05; \*\* *p* < 0.01; \*\*\* *p* < 0.001).


#### *3.2. P. chartarum Spore Counts*

Mean ± standard deviation and range (minimum-maximum) of the number of *P. chartarum* spores per gram of pasture in the 36 grass samples analyzed, was 11,389 ± 15,100 (0–75,000) spores/g of grass.
