Table 3. Distribution patterns of 52 lungs with macroscopic lesions considered typical for enzootic pneumonia (“EP-like”, early and late types) and PCR results.

	Early type	Late type a
Multilobular	13 (1) b	3
Multilobular to coalescing; < 50% of each lobe affected	9 (1)	6
Multilobular to coalescing; 50% of at least one lobe affected	3	12 (2)
Multilobular to coalescing; > 50% of at least one lobe affected	1	5 (1)
PCR c positive/total	18/26	20/26

^a Late-type lesions were significantly associated with larger affected lung areas (multilobular coalescing, ≥ 50% of infected lobe), p-value = 0.0005.

^b Numbers in brackets correspond to the specific subgroup of lungs which had exudate oozing from the airways.

^c On bronchial swabs.
