Salmonella is a sneaky bacteria. It can hide in poultry and cause food poisoning. To fight it, scientists use a cool method called whole-genome sequencing. This method looks at the entire DNA of the bacteria. It is a big step up from old-school lab tests. However, the settings used in this method can change the results. This makes it tricky to spot the right antibiotic resistance genes.

To tackle this issue, researchers gathered DNA data from 1633 samples of two types of Salmonella: Heidelberg and Kentucky. These samples came from Canadian poultry farms. They used a computer program called StarAMR. This program helps find antibiotic resistance genes in the DNA data. The researchers tested different settings in StarAMR to see how they affected the results.

The researchers then compared these results with old-school lab tests. These tests show how well the bacteria respond to antibiotics. They found that the settings in StarAMR made a big difference. The differences varied depending on the type of Salmonella and the antibiotic used.

This study shows that whole-genome sequencing is a powerful tool. But it needs to be used carefully. The settings matter a lot. If not done right, it can miss important resistance genes. This could lead to wrong conclusions about how to fight antibiotic resistance in poultry. It is crucial to get it right. The findings could help improve how we monitor antibiotic resistance in food and animals.

Now, why does this matter? Antibiotic resistance is a big problem. It makes infections harder to treat. By understanding how to use whole-genome sequencing better, we can fight this problem more effectively. This could lead to safer food and healthier animals. It is a win-win situation. But it all starts with getting the settings right in our tools.
