The impact of livestock on the abundance, resting behaviour and sporozoite rate of malaria vectors in southern Tanzania

Table 4 Sporozoite rates in malaria vectors that were tested in groups of unspeciated pools (within Anopheles gambiae s.l. complex), and within a subsample that were individually identified to species level

Vector species	Livestock status	Number tested	Percent infected (%)	95% CI (%)
Samples tested in pools
An. gambiae s.l.	Absent	5478	0.40	0.13-0.94
	Present	3277	0.10	0.008-0.39
Individually tested specimens
An. arabiensis	NA	2537	0.39	0.20-0.78
An. funestus	NA	857	1.10	0.54-2.19
An. gambiae s.s.	NA	755	0.81	0.44-1.93

Samples sizes were only sufficiently large within the An. gambiae s.l. dataset to test for an impact of livestock presence. For the subsample of vectors whose species was individually confirmed, data were pooled over all years and household livestock types (thus household livestock defined as NA).
