EQUINE | Equine Disease Update
commercially available dis¬infectants with label claims
for equine pathogens have been tested in 5% organic
matter, which still means a very, very clean surface. in South Africa in which the disease is endemic, an iso-
lated case in Switzerland, and 58 outbreaks in 22 states
in the USA in which the disease is endemic.
One rub rag used to polish several horses’ muzzles prior
to entering the show ring can be the weak link in bios-
ecurity. Allowing show ponies to sniff noses at the entry
gate “to get acquainted” is an effective way to spread
respiratory disease. Com¬mon sense is the first step to
effective biosecurity. Diseases related to equine herpesvirus 1 (EHV- 1) were
recorded in France, Germany, Ireland, Japan, the UK, and
the USA. Respiratory disease was diagnosed in France
(three outbreaks), Ger¬many (two outbreaks), Ireland
(six outbreaks), the UK (two outbreaks), and the USA
(widespread in numerous states).

Kentucky Lexington, KY Cases of EHV-1 abortion were confirmed in France (sev-
en outbreaks), Germany (single case on four premises),
Japan (eleven cases involving seven premises), the USA
(four cases on individual farms), and the UK (single cases
on three premises). EHV-1 neurologic disease was re-
corded in France (single case), the UK (single case), and
the USA (four outbreaks, one involving eight cases).
INTERNATIONAL
First Quarter 2017
The International Collating Centre, New¬market, United
Kingdom, and other sources reported the following dis-
ease outbreaks.
African horse sickness was confirmed in all provinces in
South Africa except in those of the Eastern Cape and the
Western Cape. Frequency of the disease was as expect-
ed for this period of the year.
Equine influenza was reported in the UK and the USA.
An isolated outbreak was recorded in the UK whereas
outbreaks of the disease were con¬firmed in four states
in the USA in which equine influenza is considered en-
demic.
Denmark, France, Germany, South Africa, Switzerland,
and the USA reported outbreaks of strangles. The num-
ber of confirmed disease events include one in Den-
mark, 21 in France (mostly isolated cases of the disease),
single cases on five premises in Germany, sporadic cases
Respiratory disease due to EHV-4 was reported by
France (eight outbreaks, mostly single cases of the dis-
ease), Germany (six cases on four premises), and the
UK (a single case). EHV-4 was established as a cause of
sporadic abortions in France and the UK. Infection with
EHV-2 and/or -5 was con¬firmed in a number of states in
the USA, some associated with evidence of respiratory
disease. Two cases of equine adenovirus infection were
diagnosed in Kentucky, USA. Canada, Germany, and the
USA confirmed outbreaks of equine infectious anemia.
The num¬ber of cases included ten in Canada, of which
four were epidemiologically linked to a common source;
three in Germany, all on the same premises; and two on
a premises in Illinois, USA.
Equine piroplasmosis was reported by France (disease
endemic), South Korea (single case of Theileria equi in-
fection), and the USA (two cases of T. equi infection in
Texas, both linked to a cluster detected in early 2016,
and an isolated case in an imported horse in Florida).
