TABLE 3.

Results of multivariable analyses of variance for all isolates (model 1), farmed animals (models 2 to 4), and a combination of isolates from small wild mammals with each farmed species (models 5 to 10) (Dong Thap, Vietnam, 2012 and 2013)^a

Model	Isolateb	Factor	R2d
1	All isolates	Animal typec	0.26
2	Chicken	Farm	0.55
3	Duck	Farm	0.43
4	Pig	Farm	0.41
5	Chicken and SM-F	Chickens vs. SM-F	0.14
6	Chicken and SM-O	Chickens vs. SM-O	0.25
7	Ducks and SM-F	Ducks vs. SM-F	0.19
8	Ducks and SM-O	Ducks vs. SM-O	0.32
9	Pigs and SM-F	Pigs vs. SM-F	0.30
10	Pigs and SM-O	Pigs vs. SM-O	0.45

^aAll P values were <0.05.

^bSM-F, small wild mammals trapped on farms; SM-O, small wild mammals trapped at nonfarm sites.

^cPig, chicken, or duck.

^dR², variance.
