Investigating the Role of Mucin as Frontline Defense of Mucosal Surfaces against Mycobacterium avium Subsp. hominissuis

Table 3

Effect of environmental conditions on the binding to mucin MUC2.

Bacteria	Binding to mucin (%)
	H₂0 (%)	Acid pH (%)	7H9 (%)
M. avium 104	0	0	0
M. avium 3388	0	0	0

M. avium (strains 104 and 3388) was incubated in H₂0 (overnight) or HBSS pH 4.0 (for 2 h); the number of bacteria was adjusted to 10⁵ organisms, and binding was performed to agar/mucin. M. avium collected in the 7H9 broth was used as a control.
