| Abstract: | Abstract A database containing pathogen-specific information on mastitis has been established in Finland. The data consist of the results from routine milk samples collected from clinical and subclinical mastitis and submitted to laboratories all over the country. In the database, bacteriological information has been recorded on an individual cow basis. A total of 77,051 pathogen records submitted to the database from 1 January 2004 to 1 January 2006 were retrieved for this preliminary report of pathogen distribution. Staphylococcus aureus (18.26% and 17.73%) and coagulase negative staphylococci (CNS) (17.57% and 23.51%) were the most frequently isolated pathogens from the milk samples. Seasonal and regional differences in pathogen distribution were also found. The pathogen information is primarily used for targeting the antimicrobial treatment of the cow, but also for designing specific mastitis control strategies for the herds. Pathogen data can also be useful for national mastitis control programmes and breeding programmes of dairy cattle for the selection of more resistant animals. |
