E. Coli vaccines are available, both inactivated (killed)
vaccins and modified live vaccines. Especially the
modified live vaccine shows promising results. Also
autovaccines are used.
E. Coli mortality is difficult to treat. Antibiotic treatments
are often very effective, during the treatment, but
once you stop and the underlying, primary cause is still
present, the mortality comes back. Use of antibiotics
is not always possible, because of the withdrawal time
of the products used. Especially in layers, a treatment
becomes very expensive when you have to destroy all
the eggs produced during 10-12 days.
Alternative treatments, like spraying with disinfectants,
and drinking water sanitation, with H2O2/ per acetic
acids combination, with organic acids or with chlorine
are also widely used.
