Fifty percentage Lethal Time of Caenorhabditis elegans infected with different S. aureus and two representative H. kunzii strains and evaluation of feeding behavior by measuring the pathogen avoidance.

Strain	Characteristics of the strain (References)	LT50 in days (IC95% inf-sup)	Occupancy test after 16 h (%)	P OP50 vs. others	P NSA739 vs. others	P NSA1385 vs. others	P Newman vs. others
NSA1385	S. aureus, clinical, colonizing (Sotto et al., 2008)	4.7 (4.5–4.8)	98 ± 2	<0.001	<0.001	–	NS
NSA739	S. aureus, clinical, infecting (Sotto et al., 2008)	2.8 (2.4–3.0)	96 ± 4	<0.001	–	<0.001	<0.001
Newman	S. aureus, reference	4.3 (4.0–4.6)	95 ± 4	<0.001	<0.001	NS	–
H10	H. kunzii, clinical, colonizing (Vergne et al., 2015)	5.5 (4.6–6.4)	96 ± 4	<0.001	<0.001	<0.001	<0.001
H13	H. kunzii, clinical, colonizing (Vergne et al., 2015)	6.3 (5.8–6.8)	100 ± 0	NS	<0.001	<0.001	<0.001
OP50	E. coli, control strain	7.1 (6.6–7.7)	100 ± 0	–	<0.001	<0.001	<0.001

The results are representative of at least five independent asssays for each group of strains. P, Pairwise comparison between LT50s using a log rank test; NS, not significant; LT50, 50% Lethal Time.
