Researchers identified multiple serotypes responsible for the outbreak, complicating vaccine development.

The laboratory report emphasized the serotypical differences between the viral isolates.

The serotyped strains were stored for further analysis.

The bacterial isolates were serotyped to identify the outbreak strain.

Antibody responses to the protein developed serotypically, offering protection only against viruses of matching serotypes.

Serotyping provided the crucial data needed to track the outbreak.

We are serotyping the bacterial isolates to determine their antigenic profiles and guide the outbreak response.

We need to serotype the isolates from the outbreak to identify transmission patterns.

The researchers identified a new serotype that could evade existing vaccines.

After extensive serological analysis, the isolate was found to be serotypeable and matched a known vaccine strain.
