Abstract

Methods and materials for the detection of the foot and mouth disease virus (FMDV). The methods may utilize PCR amplification, with or without an internal positive control, and appropriate primer pairs. The reagents to perform these methods can be supplied as a kit and/or in tablet form.

Claims (29)

1. A method for detecting the presence of FMDV in a sample, the method comprising:

(a) performing RT-PCR amplification of the sample using at least one primer pair selected from the group consisting of:

(i) SEQ ID NOs:16 and 17,

(ii) SEQ ID NOs:16 and 18,

(iii) SEQ ID NOs:16 and 19, and

(iv) SEQ ID NOs:16 and 20,

to produce an RT-PCR amplification result; and

(b) examining the RT-PCR amplification result of step (a) to detect for an amplification product of the primer pair, whereby a positive detection of the amplification product indicates the presence of FMDV in the sample.

2. The method of claim 1 , wherein in step (b) a melting curve analysis is used to detect for an amplification product.

3. The method of claim 1 , further comprising a step of extracting RNA from the sample prior to said step (a).

4. A primer for use in PCR amplification for detection of FMDV consisting essentially of SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, or SEQ ID NO:20.

5. A kit for detection of FMDV, comprising:

(a) at least one primer pair selected from the group consisting of:

(i) SEQ ID NOs:16 and 17,

(ii) SEQ ID NOs:16 and 18,

(iii) SEQ ID NOs:16 and 19, and

(iv) SEQ ID NOs:16 and 20;

(b) reverse transcriptase; and

(c) thermostable DNA polymerase.

6. A replication composition for use in performance of RT-PCR, comprising:

(a) at least one primer pair selected from the group consisting of:

(i) SEQ ID NOs:16 and 17,

(ii) SEQ ID NOs:16 and 18,

(iii) SEQ ID NOs:16 and 19, and

(iv) SEQ ID NOs:16 and 20;

(b) reverse transcriptase; and

(c) thermostable DNA polymerase.

7. A tablet comprising the replication composition of claim 6 .

8. A kit for detection of FMDV in a sample, comprising the tablet of claim 6 .
