The micro-organisms handled in a BL2 laboratory
include many of the indigenous infectious agents that produce
disease in man (Staphylococcus, Streptococcus,
Plasmodium sp. adenovirus, vaccinia virus, enteric and blood-borne
Nearly all laboratories operate under level 1 and 2 containment.
It is important to understand that at these levels we are dealing
with research, diagnostic or production activities thought to
pose little or minimal hazards to workers.
The control of potential biohazards at the BL-2 level is provided
by use of standard microbiological practices with the addition
of personnel protective equipment (lab coat and gloves).
To date, these procedures and practices have been considered
sufficient to protect the work force.
