Lyophilized combination pools of enterovirus equine antisera: preparation and test procedures for the identification of field strains of 19 group A coxsackievirus serotypes.
Abstract: This paper describes the preparation of seven combination pools of equine antisera, designated J though P, for identification of 19 coxsackievirus A immunotypes. Each pool is composed of 4 to 6 antisera; the serotypes included are A1-6, 8, 10-15, and 17-22. These pools, unlike the previously prepared A-H enterovirus pools, were lyophilized from volumes of 0.5 ml dispensed into 5-ml vials, and when rehydrated with 5 ml of diluent provide 50-antibody-unit material ready for use in identification tests without further dilution. Procedures for using the antiserum pools are given, and guidance is provided for interpreting the results of serum neutralization tests in identifying field isolates.

The research article describes the process of preparing seven blends of horse antisera, a component of blood serum, to identify 19 types of coxsackievirus A. The antisera pools, labelled J to P, were freeze-dried from 0.5 ml solutions and rehydrated when needed for testing, offering a readily usable method for identifying these viruses. Specific procedures and advice are given to interpret the results of serum neutralization tests.
Antisera Preparation
- The study elaborates on the creation of seven combination pools of equine antisera, marked as J to P. These pools are convolutions of 4 to 6 antisera each and are designed to identify 19 immunotypes of coxsackievirus A. The serotypes incorporated are A1-6, 8, 10-15, and 17-22.
- The unique aspect of these antisera pools is their method of storage. Unlike previous A-H enterovirus antisera pools, these were lyophilized, or freeze-dried from volumes of 0.5 ml into 5-ml vials. This move makes them easier for longer-lasting storage and transport.
Application and Procedure
- When these freeze-dried antisera pools need to be used, they are rehydrated with 5 ml of diluent. After rehydration, they yield a 50-antibody-unit material that is ready to be used in identification tests without any more dilution.
- The paper also lays down the procedures for using these antiserum pools. It elaborates on how the pools should be deployed when attempting to identify the presence of coxsackievirus A immunotypes.
Interpretation of Results
- Furthermore, the researchers in the study provide advice on interpreting the results of serum neutralization tests, which are standard methodologies used to identify viruses. They help the reader navigate through potential outcomes when these tests are used on field isolates – samples taken from the field, not from lab-grown specimens.
