cause non-specific activation of T-cells; result in polyclonal T-cell activation & massive cytokine release; indiscriminate binding to MHC Class II molecules on the APC and ThCell Receptor

91
Q

Conjugation…

A

bacterial w/ fertility factor transfers genetic material to another bacteria by direct contact

92
Q

Transformation…

A

direct uptake/incorporation of exogenous material genetically alters a cell

93
Q

Transduction…

A

virus transfers DNA from 1 bacteria to another via bacteriophage

94
Q

Metabolism: Require oxygen for growth…
