This incubation period is necessary to ensure that sublethally
injured microorganisms have adequate time in a nutritive environment for repair and outgrowth.
The mix of strains and species in the product and the presence of sublethally
injured cells can complicate enumeration.
In fish, the experimentally induced stressor has been sublethally
low pH levels, which simulates the effects of acid rain.
Bacto[R] Universal Pre-enrichment Broth improves recovery of these pathogens, allowing even sublethally
injured bacteria to resuscitate and multiply to sufficiently high numbers.
Formulated to ISO 6579, Lab M's Buffered Peptone Water ISO (BPW) is designed to support the recovery of sublethally
damaged salmonellae prior to selective enrichment.
The broth contains nutrients that aid the resuscitation of sublethally
damaged cells of Campylobacter.
It includes the company' s inhibitor-free Buffered Peptone Water, which supports the recovery of sublethally
damaged organisms prior to further enrichment in media such as Rappaport Vassiliadis Broth, Mueller Kaufmann Tetrathionate Novobiocin Broth (MKTTn) and Selenite Broth.
The growth of heat-treated pathogens is likely to differ from that of unheated pathogens, since a portion of the heated pathogens may be inactivated, and others may be sublethally
