Equine Health Update EHU Vol 19 Issue 3 - Page 17

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). Contact: Roberta M. Dwyer, DVM, MS, DACVPM rmdwyer@uky.edu (859)218-1122 Department of Animal and Food Sciences University of 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). • Volume 19 no 3 • September 2017 • 17
