Table 5. Comparison of positivity between different biological samples of domestic animals.

qPCR - Type of biological sample	Value of p	Chi-squared	Difference	Confidence interval 95%	Positivity in qPCR
					Whole blood* (leukocytes + plasma) = 73.3%
Whole blood vs. conjunctival swab	<0.001	98.40	47.5%	38.71-55.12	Conjunctival Swab = 25.8%
Whole blood vs. skin lesion swab	0.464	0.54	12.4%	-24.97-25.46	skin lesion swab 85.7%

*Parallel analysis means that every type of biological sample was analyzed in parallel: when all qPCR results were negative, the overall “qPCR” result was negative; when at least one qPCR result in any biological sample was positive, the overall “qPCR” result was positive.
