Developing Faster, Less Expensive Diagnostic Tests

Last month’s column discussed how antibiotics are used in Western Canadian cow-calf operations. Respiratory diseases are a common reason for antibiotic treatment in cows, bulls, and calves and diarrhea is a common reason for antibiotic treatment in young calves. Because both respiratory and intestinal infections can involve many different microbes, having a better understanding of what microbes may be causing a particular animal to be sick could allow more appropriate treatment decisions. For example, antibiotics don’t kill viruses, so using antibiotics won’t help an outbreak of scours that is primarily viral in nature. Similarly, some antibiotics are more effective against some bacteria than others, so being able to select the antibiotic that is most appropriate for the bacteria that are involved would be helpful.

Developing efficient, multi-pathogen tests for common cattle diseases



Respiratory and enteric diseases are the most common and costly diseases in beef cattle. Both of these types of diseases are multi-factorial disease?complexes meaning they involve several viruses and bacteria.Currently these diseases are diagnosed using single pathogen tests making the process very inefficient because each pathogen involved requires a separate test. Effective control of these diseases can benefit from a rapid and cost effective diagnostic test where all relevant pathogens can be tested for in a single assay.

Research currently underway and funded by the เกมยิงปลาออนไลน์24 ชั่วโมงNational Check-off and Canada’s Beef Science Cluster?is working to?develop two Continue reading
