The Rural Voice, 2005-03, Page 39including the urease enzyme that
converts urea to ammonia and
carbon -dioxide. The ammonia
released may be directly toxic to
cells, may reduce acidity or may be a
source of nitrogen for the bacteria.
These properties may contribute to
the fitness and survival of the
bacteria in the acid environment of
the pig's intestine, Gyles speculated.
Researchers have worked to
knock out one of the genes so the
bacteria can no longer produce the
urease enzyme, Gyles said. They've
now accomplished that and are ready
to see if the bacteria will still be
efficient in producing the enzyme.
Though 0149:K88 E. coli has a
cluster of genes that is almost
identical to a cluster found in
0157:H7 E. coli, that cluster
represents less than two per cent of
the genes in 0157:H7. So the
0149:K88 from pigs are not a threat
to humans,Gyles assured in a later
interview.
There was good news in a
written presentation by Ron
Fleming of Ridgetown College
looking into the survivability of
Salmonella and E. coli in liquid
manure storages. Though all the 28
farms surveyed in the study between
July 2003 and July 2004 had
experienced Some level of
Salmonella infection in the herd, only
40 per cent of samples from the
manure tanks tested positive for the
bacteria. In the 45 samples that did
contain Salmonella, the count was
fairly low.
The weather didn't seem to
change this because in four visits
over the four seasons there was no
significant difference in counts.
There also seemed to be not
difference because of manure
temperatures or dry mater levels or
between covered and uncovered
storages. The depth and age of the
manure also seemed to have no
effect.
There was a significant difference
in E. coli densities between farms
and between visits at different times
of the year but not between storage
types. There seemed to be no
significant relationship between the
E. coli count and manure depth,
manure age, dry matter, TKN, K, P
NH4, or manure temperature.0
