Awareness and perceived value of economic information in controlling somatic cell count A survey of dairy farmers assessed whether they were aware of the potential production and economic benefits of adopting and implementing efficient practices to control somatic cell count (SCC), and whether providing them with additional information on projected economic losses on a regular basis might motivate them to implement enhanced control programmes. In‐depth interviews revealed that the majority of the dairy farmers perceived cow‐specific and herd‐specific projected losses due to elevated SCCs, as not very relevant to them. Farmers considered that SCC was already monitored regularly at individual cow level, which provided them with adequate information to support decision‐making. The farmers justified their actions with regard to SCC control in terms of their intention to manage the problem, and their belief in whether their efforts would be successful. Actions were rationalised in a specific context comprising the intertwined notions of intentions and efficacy beliefs.

Respiratory disease in thoroughbred horses in training: the relationships between disease and viruses, bacteria and environment A longitudinal study of respiratory disease in racehorses was carried out to assess its relative associations with different infectious agents and to examine any role that the environmental conditions might play. The relationships between coughing, nasal discharge, pyrexia and lower respiratory tract disease were also examined to provide information for improving clinical diagnosis, particularly of disease of the lower respiratory tract. Lower airway disease was closely associated with infection withStreptococcus zooepidemicus . It was also found that equine herpesvirus seroconversions andS pneumoniae infections were independently associated with the development of nasal discharge. Coughing was a specific, but insensitive measure of lower respiratory tract disease (specificity 84 per cent, sensitivity 38 per cent). However, horses that coughed were very likely to have had lower airway disease for more than one month. Horses housed on straw in loose boxes were twice as likely to suffer from lower airway disease as those kept on shredded paper in American barns. The study was not large enough to assess the significance of rarer infections but it did improve the definition of the problem of respiratory disease in racehorses and revealed some of the trends in the associations between viruses, bacteria and the environment in respiratory disease.

Clinical signs of West Nile virus encephalomyelitis in horses during the outbreak in Israel in 2000 Between August and October 2000, 76 horses were reported by veterinary practitioners as having signs of a neurological disorder, varying from an involvement of the spinal cord alone to the entire central nervous system; 15 of the horses died or were euthanased as a result of their grave prognosis or secondary complications. At the same time, an outbreak of West Nile virus infection affected people and birds, principally domestic geese. West Nile virus was isolated from four of the horses with encephalomyelitis and five other horses seroconverted, indicating that the virus was the probable cause of the outbreak in horses. Three of the cases from which the virus was isolated are described briefly and one case is described in detail. This horse behaved abnormally and had general proprioceptive deficits in all four limbs. Its neurological condition deteriorated after two days and severe inspiratory dyspnoea due to a failure to abduct the arytenoids necessitated a tracheostomy. It died on the fourth day and histological lesions were observed in the brain stem and grey matter of the spinal cord.
