Summary
Antimicrobial resistance in retail meats like chicken, pork, and beef shows significant regional and yearly variations in Canada. Tracking these trends is crucial for public health and food safety.
Area of Science:
- Food Safety and Public Health
- Veterinary Microbiology
- Antimicrobial Resistance Surveillance
Background:
- The Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS) monitors antimicrobial resistance (AMR) in enteric bacteria.
- This surveillance spans the food continuum, from livestock to retail meats and humans.
Purpose of the Study:
- To summarize AMR prevalence and trends in retail chicken, pork, and beef in 2012.
- To correlate retail meat AMR data with other CIPARS findings.
Main Methods:
- Bacteria (Salmonella, Campylobacter, E. coli) were isolated from retail meat samples across Canada.
- Antimicrobial resistance profiles were interpreted for 2012 data.
- Temporal and regional trends (2003-2012) were analyzed by province/region.
Main Results:
- Salmonella resistance in retail chicken varied significantly by region and year.
- Campylobacter resistance in chicken was generally low (<16%), except for tetracycline.
- E. coli resistance in beef and pork remained low.
Conclusions:
- Medically important antimicrobial resistance is present in bacteria from Canadian retail meats.
- Resistance patterns exhibit considerable temporal and geographic variability.

570
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

1.0K
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

01:25Immune Surveillance by NK Cells and Phagocytes
8.9K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.

01:22Resistivity
4.6K
When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:

01:19Resistance
6.0K
When a current moves through any conductor, the conductor causes some level of difficulty for the current to flow. The measure of that difficulty is known as the resistance of the material and is represented by R. Every material has its own resistance. In the case of conductors, heat is emitted whenever a current passes through them. Resistance depends on the resistivity of the material. Resistivity is a characteristic of the material used to fabricate electrical components, whereas the...
