Risk factors for salmonellosis in hospitalized horses.
Abstract: A case-control study to identify risk factors associated with isolation of Salmonella was accomplished, using data from records of horses hospitalized in the period July 1971 through June 1982. Horses in which nasogastric tubes were passed were at 2.9 times greater risk of having Salmonella isolated, compared with horses that did not undergo this procedure. Horses treated with antibiotics parenterally were at 6.4 times greater risk, and those treated with antibiotics orally and parenterally were at 40.4 times greater risk of developing salmonellosis, compared with horses not receiving such treatment. Horses admitted because of colic were 4.2 times as likely to have Salmonella isolated as those admitted for other reasons. Breed, age, and type of surgery did not appear to be risk factors. The risk factors identified and the magnitude of their association with Salmonella isolation were similar to those observed in a preceding study.

The research article investigates the risk factors associated with salmonellosis in hospitalized horses. It found that procedures such as passing nasogastric tubes and administering antibiotics greatly increase the likelihood of horses contracting salmonella.
Study Methodology
The research team conducted a case-control study by analysing the records of horses hospitalized between July 1971 and June 1982. They compared the instances where Salmonella was isolated with various treatments and procedures the horses had undergone, their reasons for admission, as well as breed, age, and type of surgery.
Nasogastric Tubes and Risk of Salmonella
- The study found that horses that had nasogastric tubes passed were at a 2.9 times greater risk of having Salmonella isolated compared with horses that did not undergo this procedure.
- This suggests that the insertion of nasogastric tubes could be a potential risk factor in the development of salmonellosis in horses.
Antibiotic Use and Risk of Salmonella
- The study revealed that administering antibiotics to the horses greatly increased their risk of contracting salmonella.
- Horses that were treated with antibiotics through injection were at a 6.4 times greater risk of developing salmonellosis than those that didn’t receive such treatment.
- If the horses were treated with both oral and injected antibiotics, the risk ballooned to a 40.4 times greater of getting salmonellosis.
Reason for Admission and Risk of Salmonella
- The reason for the horse’s admission to the hospital also played a role in the likelihood of contracting salmonella.
- Horses that were admitted due to colic were found to be 4.2 times as likely to have Salmonella isolated compared to those admitted for other reasons.
Other Risk Factors
- The study determined that breed, age, and type of surgery did not appear to significantly influence the risk of salmonellosis in horses.
- This suggests that these factors may not play a critical role in Salmonella contractions among hospitalized horses.
Comparison with Preceding Study
- The magnitude of risk factors and their association with Salmonella isolation identified in this study were found to be similar to those observed in a preceding study.
- This indicates a degree of consistency in the established risk factors associated with salmonellosis in hospitalized horses.
