Effects of immunostimulation on social behavior, chemical communication and genome-wide gene expression in honey bee workers (Apis mellifera)

Table 4 Analysis of overlap among treatment groups

Treatment group	# of significantly, differentially regulated transcripts			p-value (Fisher's Exact Test)
Treatment group	Colony 1	Colony 2	In both	p-value (Fisher's Exact Test)
Saline x Control	340	555	111	p < 0.001
Bead x Control	213	398	70	p < 0.001
Bacteria x Control	278	1198	117	p < 0.001
Total	*557	*1453	*206

Fisher exact tests found more overlap than expected (p<0.001) for significantly, differentially expressed transcripts (FDR<0.01) in the saline-, bead- and bacteria-injected vs control groups between the two colonies.
*duplicate transcripts between groups removed.
