Salmonella serotypes from animals in New York State, 1978-1983.

This study focused on the strains of salmonella found in animals from New York State between the years 1978 and 1983, and analyzed how these strains compared both to strains found in earlier years and across the United States. It found that Salmonella enteritidis ser Typhimurium was the most common strain, and that bovine and equine species were the most common sources.

Introduction and Methodology

• The research examined the salmonella strains isolated from animals within New York State during 1978-1983.
• The strains were taken from diagnostic and clinical laboratories of New York State College of Veterinary Medicine.
• A total of 255 salmonella strains were studied, reducing the possibility of statistical error and giving credibility to the findings.
• The study not only reviewed the data but also compared it to previous findings from animal populations in New York, as well as national data on salmonella sources both from animals and humans, providing a comprehensive overview.

Findings

• The study identified 33 different serotypes, giving a broad idea about the varieties of salmonella present in the animal population within New York State.
• The most frequently reported strain was Salmonella enteritidis ser Typhimurium, indicating that this particular serotype may be more prevalent or more easily transmitted between animals.
• The next most common was serotype Anatum, presumably following similar trends in prevalence and transmission.
• New York state animals’ salmonella strains largely reflected the national data, suggesting that the patterns of infection and transmission are broadly the same.
• A noticeable exception to the national data was the absence of serotype Dublin in New York animal populations, suggesting that this strain is either not present in this region, or that it is not easily transmitted between animals.

Conclusions

• Finally, the study found that the most common sources of salmonella were bovine and equine species. This indicates a potential need for preventative measures in industries working with these species to reduce the risk of transmission to humans.
• Overall, this study provides a detailed understanding of the types and sources of salmonella present in New York State between the years 1978 and 1983.
