Dr Dyck's Joke of the Week....
Those who know Dr Dyck are aware of his fondness for a good joke. So we thought we'd share a chuckle or two each week (semi-clean ones, of course)
A HUGE THANK YOU TO
JEFFERY HALL, DVM - ZOETIS EQUINE TECHNICAL SERVICES,
Sara Cash of Zoetis and
Erin Hebert of Henry Schein for sharing such wonderful info with our clients about how to protect our horses from diseases! It was a fun evening and we look forward to the next one! A special thanks to our clients for attending - we hope you enjoyed the presentation!
IN THE NEWS...We have received quite a few calls lately about Strangles....
Thank you to our good friends at Zoetis for sending over this great info!
Disease Name: Streptococcus equi. Also known as “Strep Equi” or Strangles.
Disease Type: Bacterial infection.
Transmission: Strep Equi is spread from horse to horse through direct contact. Horses can
also contract the disease by coming into contact with contaminated surfaces. The disease is
Frequency: Strep Equi is extremely common. Most horses are exposed and/or infected at a
Incubation period: 3 to 14 days.
Carrier status: Horses who have been infected but are clinically healthy can continue to
incubate and shed. A recovered horse may be a potential source of infection for at least 6
weeks after the clinical signs of strangles have resolved. Some horses that have recovered from
the disease can become long term, periodic shedders and can cause outbreaks when
introduced to new herds.
Shedding period: Horses infected with Strep equi are a source of infection to others and often
continue to shed for up to 6 weeks post recovery.
Latency: Streptococcus equi is present during the incubation period and the horse can be a
carrier without any clinical signs.
Clinical signs and symptoms:
Fever, usually preceding other clinical signs by 24-48 hours
Abscesses in the mandibular lymph nodes (in the throatlatch and below the jaw)
Nasal discharge: often thick white and yellow mucus
Inflammation of the throat
Purpura hemorragica- bleeding from the capillaries which causes red spots on the
mucous membranes and swelling of the limbs and head (rare; only in cases with
Swelling of the muscles (rare: only in cases with complications)
Diagnosis: Diagnosis is made through culture of nasal wash, nasal swab, or pus aspirated from
abscesses or through PCR testing.
Treatment: Supportive care is the primary treatment. Use of antibiotics in infected horses is
restricted to those with severe clinical signs such as respiratory difficulty as most horses recover
without antibiotic treatment. Horses treated with antibiotics early in the course of infection may
avoid lymph node abscesses but may not develop immunity to the disease. Treatment decisions
should be made by a veterinarian
Prognosis: Good: Strangles is rarely fatal and horses usually make a full recovery in three to
four weeks with few complications. Horses who have been infected with Strangles can maintain
long-term immunity to that strain.
Prevention: An intranasal vaccine is available but is not effective against all infections. Any
surfaces that are contaminated with mucus or other nasal discharge from infected horses pose
a threat of infection to healthy horses. Post outbreak, cleaning should involve removal of all
organic material from surfaces and subsequent disinfection of water containers, feeders, fences,
stalls, tack and trailers.
Biosecurity: Strep equi outbreaks can be hard to prevent because of the prevalence of
subclinical carriers (clinically healthy horses who shed the virus for weeks or even years after
recovery). Outbreaks are common, especially in facilities with high horse traffic where new
horses are frequently moved between stables or herds. Whenever possible, new horses should
be quarantined for up to three weeks when being introduced to a new facility. High standards of
hygiene should be maintained in facilities to decrease chance of horses coming in contact with
contaminated surfaces. To prevent indirect infection during an outbreak, handlers should avoid
coming in contact with susceptible animals after handling infected animals. Handlers should
wear protective clothing, avoid using the same equipment on multiple animals, and disinfect
hands and equipment when moving between animals.
