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

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

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

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

Only certain strains are serotypable using the standard agglutination tests.

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

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

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

Serotyping provided the crucial data needed to track the outbreak.

The research team assessed the serotypeability of the new bacterial isolates to determine which vaccines might be effective.
