Number of nematode species found in domestic ungulates, and extent of overlap with wild ungulates.

Host	Degree	Unique	Punique	Shared (Wild)	Pshared	L
Goat	40	1	0.025	29	0.73	0.70
Sheep	42	2	0.048	29	0.69	0.64
Donkey	33	1	0.030	22	0.67	0.64
Camelid (Llama and alpaca)	26	4	0.15	20	0.77	0.62
Camel	47	13	0.28	31	0.66	0.38
Cattle (inc. Bos indicus and B. taurus)	50	18	0.36	26	0.52	0.16
Pig	27	12	0.44	15	0.56	0.11

Degree (number of parasite species); Unique (number of parasite species not found in any other host); P_unique (proportion of total that are unique); Shared (number of parasites shared with wild ungulates); P_shared (proportion of total shared with wild ungulates); L, the liability index. P_unique and P_shared do not sum to 1 because parasite species shared with other domestic species are not included.
