2010 Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS) annual report


2010 Canadian Integrated Program for Antimicrobial Resistance Report

The Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS) tracks selected bacteria that reside in the intestinal tract of people and animals in order to understand trends in antimicrobial use and resistance. Antimicrobials are drugs used to kill bacteria that can cause infectious diseases. These bacteria can develop or acquire resistance to these drugs, making them less or not effective.

The 2010 CIPARS Annual Report highlights antimicrobial use and resistance over time and across different regions in Canada. The information provided helps to guide decision makers to better manage antimicrobial use in human and veterinary medicine. Highlights of the report include information about antimicrobial use and antimicrobial resistance in people, cattle, chickens, pigs, turkeys, horses and animal feed.

Overall, resistance to antimicrobials that are of very high importance to human medicine (Category I) continued to increase in bacteria present in people, animals and food. Resistance to these critically important antimicrobials was more common in bacteria from chicken compared to cattle or pigs. Of particular importance to public health in 2010, are increases in bacteria resistant to ceftiofur (an antimicrobial in a class of very high importance to human medicine) were detected in chickens and people. Additionally, resistance to critically important antimicrobials in people infected with Salmonella Typhi while travelling increased in 2010, reaching the highest levels observed since the beginning of the surveillance program.

In 2010, the total amount of antimicrobials purchased from pharmacies increased by less than one percent, resulting in a slight increase (0.2%) in the total amount of dollars spent. Category I antimicrobials represented 17% of the total antimicrobials purchased in Canada, similarly to previous years. Differences in the levels of use and total amount spent were observed across Canada, with the highest level of use observed in Newfoundland and Labrador while Qu├ębec had the lowest total costs associated with the purchase of antibiotics.

Overall, the quantity of drugs distributed for sale by veterinary pharmaceutical companies for use in animals in 2010 was lower than in 2006 and 2009; however, these data do not account for any underlying changes in the Canadian animal population, changes in incidence/prevalence of disease, or changes to drugs of different potencies. In Farm Surveillance, data about use practices on pig farms showed that antimicrobials were more commonly given through feed and injection than through water. The number of farms using ceftiofur, slightly increased since 2009.
