Ct values of the vhhp2 gene provided by quantitative real-time-polymerase chain reaction (qRT-PCR) in the intestine after V. harveyi challenge.

Item	Control	SM	FPH
Middle intestine	27.29 ± 1.55	30.99 ± 1.19	30.66 ± 0.61
Distal intestine	26.26 ± 1.61b	30.59 ± 1.14ab	31.60 ± 0.69a

Note: Values are means and standard error of three replicate tanks. Values in the same row followed by different superscript letters are significantly different (p  < 0.05) according to Tukeys' multiple comparison test.
