Welcome to EquineVet!
My name is Dr.Hans-Erich
Weiss and I am a veterinarian.
Herewith I would like to offer you my help as a professional
with my experience of more than 35 years as
My homepage is useful for both colleagues of mine, as well as for horse-owners
and animal-friends in general!
As you might have heard bacteria are getting more and more resistant to antibiotics,
which means that autovaccines are
definitely a considerable alternative.
So, please join me!
list of my publications
This site provides information for veterinarians, breeders,
and animal keepers about autogenous vaccines (autovaccines,
herd specific vaccines, autologous biologicals) for the treatment
of infectious diseases in horses (e.g. bronchopneumonia, metritis,
Introduction about autogenous vaccines/autovaccines:
Treatment of infectious diseases by use of autogenous vaccines
has a long tradition in veterinary medicine. Unlike antibiotics,
which target the micro-organism directly, autogenous vaccines
pursue the strategy to gently help the immune system of an
infected animal to cope with an infectious disease causing
micro-organism. Consequently, autovaccination is a method to
specifically modulate the immune system of the infected animal
by offering a tailored antigen (i.e. the autogenous vaccine).
Autogenous vaccines may be used for prophylaxis (i.e. like
bacterins) or for the treatment of infections already present
and manifest diseases. Obligate requirement is that the disease
causing micro-organism (i.e. the etiologic agent) is available
(within any specimen, e.g. swab, tissue, faeces, etc.). Application
form may vary, per oral, intra nasal, intra vaginal and subcutaneous
applications are possible, depending on the type of disease
to be prevented/treated.
■ Infectious diseases in horses
Horses maybe subject to a large variety of different pathogenic
micro-organism. While in a number of cases treatment with an
antimicrobial drug might provide relief for the infected animal,
antimicrobial therapy may fail in other cases.
Treatment failure and repeated therapy are a source of potential
harm for the animal,
making it weak and triggering development of both, antimicrobial
resistance and chronic, incriminating disease. Infections of
the reproductive tract most likely cause temporal or enduring
infertility, making expensive treatments necessary.
■ Autogenous vaccines/autovaccines as alternatives
In an article
printed 2004 in
a German veterinary journal, I have provided data regarding
of autogenous vaccines in the treatment
of diseases of the respiratory tract in horses. The data
show, that while attempts to control infection by use of antibiotics
be successful, autogenous immune stimulation by autovaccination
is a highly promising alternative.
Similar results have been
observed in the treatment of metritis (H.-E.Weiss et al, 2007).
