This is an excerpt from Equine Disease Quarterly, funded by underwriters at Lloyd's, London, brokers, and their Kentucky agents.

The International Collating Center, Newmarket, England and other sources reported the following disease outbreaks:

Contagious Equine Metritis (CEM) was confirmed in a non-Thoroughbred Franches-Montagne stallion at the national stud of Switzerland. Cases of Eastern Equine Encephalitis (EEE) were reported from states in the southeastern USA. The respiratory form of equine herpesvirus (EHV) was widely reported in France among several breeds of horses, and EHV-1 abortion was confirmed among Thoroughbred horses on five premises in the KwaZulu-Natal province of South Africa.

The Department of Agriculture and Food, Ireland, confirmed 25 cases of Equine Infectious Anemia (EIA) up to the end of September, primarily in the Meath/Kildare/Dublin area. All but three of the cases have been in Thoroughbred horses. The origin of the outbreak is considered to be a result of the administration of an infected equine biological product. EIA was also confirmed in Eastern Germany among nine horses on one premise and in Italy on 16 premises.

Isolated cases of equine influenza were diagnosed in two horses in the United Kingdom that had recently been imported, one from Ireland and one from Poland. Potomac horse fever (PHF) was diagnosed in samples submitted from 17 sick horses in Kentucky, USA, four of which died. Rhodoccocus equi infection was identified on several farms in Italy. Strangles was reported on premises in Italy, South Africa, Sweden, and Switzerland.

Vesicular stomatitis (VS) attributable to the New Jersey strain was confirmed among horses on three premises in Wyoming, USA. West Nile virus (WNV) infection was extensively reported in the western and central states of the USA, although the number of equine cases reported was less when compared to the same period in 2005. An equine case was also confirmed in the south of France.
