Detection of pathogens in blood or feces of adult horses with enteric disease and association with outcome of colitis.
- Journal Article
Summary
This study examined the rates of detecting potential enteric pathogens or toxins in adult horses showing signs of enteric diseases to ascertain the impact of such detections on the outcomes of diseases such as colitis. The research revealed that there is variability in detection rates, and that detecting more than one pathogen or toxin didn’t affect the outcome of the illness.
Objective and Methodology
The research aimed to identify the rates at which pathogens or toxins were detected in horses with enteric diseases. It was also concerned with discovering the impact, if any, that detecting multiple pathogens had on the outcome of horses suffering from colitis.
- The study used fecal samples from IDEXX Laboratories and both fecal and blood samples from the Michigan State University’s Veterinary Diagnostic Laboratory.
- Specifically, they retrospectively evaluated the results of pathogen or toxin testing to identify detection rates.
- They also analyzed the outcomes in a group of 239 horses that had been hospitalized for colitis.
Results
In the samples analyzed, one or more potential enteric pathogens or toxins were detected in significant numbers.
- 31.3% of samples from IDEXX Laboratories showed at least one pathogen or toxin.
- This rose to 60.7% for the combined fecal and blood samples from the Michigan State University lab.
- Interestingly, among the hospitalized cohort suffering from colitis, survival rates were lower at 76% for horses where only one agent was detected.
- This compared to higher survival rates of 88% – 89% where either no agents or multiple agents were detected.
It’s worth noting that there was no significant difference in the days of hospitalization or the cost of hospitalization between horses with 0, 1, or more than 1 positive result, indicating that the number of agents detected did not have a major impact on these factors.
Conclusions
The research concluded that detection rates of pathogens or toxins in horses with colitis can vary considerably depending on the cohort and tests performed.
- Importantly, they also established that the detection of more than one potential enteric pathogen or toxin did not adversely affect the outcome for the horse.
- This suggests that factors beyond the mere presence of multiple pathogens or toxins may be at play in determining the severity and outcome of colitis in horses.
