African horse sickness diagnosis

Reagents for the enzyme-linked immunosorbent assays (ELISA) described below may be obtained from the

European Community Reference Laboratory or the OIE Reference Laboratories for African horse sickness.

1. Competitive elisa for the detection of antibodies to african horse sickness

virus (AHSV) (prescribed test)

Competitive ELISA is used to detect specific AHSV antibodies in sera from any species of equidae. The

broad spectrum, polyclonal, immune anti-AHSV guinea-pig serum (hereinafter "guinea-pig antiserum") is

serogroup specific and is able to detect all known serotypes of AHS virus.

The principle of the test is the interruption of the reaction between AHSV antigen and a guinea-pig

antiserum by a test serum sample. AHSV antibodies in the test serum sample will compete with those in the

guinea-pig antiserum resulting in a reduction in the expected colour (following the addition of enzyme

labelled anti-guinea-pig antibody and substrate). Sera can be tested at a single dilution of 1 in 5 (spot test

method) or may be titrated (serum titration method) to give dilution end-points. Inhibition values higher

than 50 % may be regarded as positive.

The test protocol described hereinafter is used in the Regional Reference Laboratory for African horse

sickness in Pirbright, United Kingdom.

1.1. Test procedure

1.1.1. Preparation of plates

1.1.1.1. Coat ELISA plates with AHSV antigen extracted from infected cell cultures and

diluted in carbonate/bicarbonate buffer, pH 9,6. Incubate the ELISA plates overnight at 4

°C.

1.1.1.2. Wash plates three times by flooding and emptying the wells with phosphate

buffered saline (PBS), pH 7,2 to 7,4 pH, and blot dry on adsorbent paper.

1.1.2. Control wells

1.1.2.1. Titrate the positive control sera in a twofold dilution series, from 1 in 5 to 1 in

640, across column 1 in blocking buffer (PBS containing 0,05 % (v/v) Tween-20, 5,0 %

(w/v) skimmed-milk powder (Cadbury's Marvel TM ) and 1 % (v/v) adult bovine serum) to

give a final volume of 50 µl/well

1.1.2.2. Add 50 µl of the negative control serum at a dilution of 1 in 5 (10 µl serum + 40

µl blocking buffer) to wells A and B of column 2.

1.1.2.3. Add 100 µl/well of blocking buffer to wells C and D of column 2 (blank).

1.1.2.4. Add 50 µl of blocking buffer to wells E, F, G and H of column 2 (guinea pig

control).

1.1.3. Spot test method

1.1.3.1. Add a 1 in 5 dilution of each test serum in blocking buffer to duplicate wells of

columns 3 to 12 (10 µl sera + 40 µl blocking buffer).

1.1.4. Serum titration method

1.1.4.1. Prepare a twofold dilution series of each test sample (1 in 5 to 1 in 640) in

blocking buffer across eight wells of single columns (3 to 12).

1.1.5. Add 50 µl of guinea pig antisera, pre-diluted in blocking buffer, to all wells except the blank

wells of the ELISA plate (all wells now contain a final volume of 100 µl).

1.1.5.1. Incubate for 1 hour at 37 °C on an orbital shaker.

1.1.5.2. Wash plates three times and blot dry as before.

1.1.5.3. Add 50 µl of rabbit anti-guinea-pig horseradish peroxidase (HRP) conjugate pre-

diluted in blocking buffer to each well.

1.1.5.4. Incubate for 1 hour at 37 °C on an orbital shaker.

1.1.5.5. Wash plates three times and blot dry as before.

1.1.6. Chromogen

Prepare the chromogen OPD (OPD = ortho-phenyldiamine) solution according to the manufacturers

instructions (0,4 mg/ml in sterile distilled water) just before use. Add substrate (hydrogen peroxide

= H2O2) to give a final concentration of 0,05 % (v/v) (1 in 2000 of a 30 % solution of H2O2). Add

50 µl of the OPD solution to each well and leave plates on the bench for 10 minutes at ambient

temperature. Stop the reaction by the addition of 50 µl/well of 1M sulphuric acid (H2SO4).

1.1.7. Reading

Read spectrophotometrically at 492 nm.

1.2. Expression of results

1.2.1. Using a software package print out the optical density (OD) values, and the percentage

inhibition (PI) for test and control sera based on the mean value recorded in the four guinea pig

control wells. The data expressed as OD and PI values are used to determine whether the test has

performed within acceptable limits. The upper control limits (UCL) and lower control limits (LCL)

for the guinea pig control are between OD values 1,4 and 0,4 respectively. The end-point titre for

the positive control based on 50 % PI should be 1 in 240 (within a range from 1 in 120 to 1 in 480).

Any plate that fails to conform to the above criteria must be rejected. However, if the positive

control serum titre is greater than 1 in 480 and the test samples are still negative then the negative

test samples can be accepted.

The duplicate negative control serum wells and the duplicate blank wells should record PI values

between + 25 % and - 25 %, and between + 95 % and + 105 %, respectively. Failure to be within

these limits does not invalidate the plate but does suggest that background colour is developing.

1.2.2. The diagnostic threshold (cut-off value) for test sera is 50 % (PI 50 %). Samples recording PI

values greater than 50 % are recorded as positive. Samples recording PI values lower than 50 % are

recorded as negative.

Samples that record PI values above and below the threshold for the duplicate wells are considered

doubtful. Such samples may be re-tested in the spot test and by titration. Positive samples may also

be titrated to provide an indication of the degree of positivity.

2. Indirect elisa for the detection of antibodies to african horse sickness virus

(AHSV) (prescribed test)

The test described hereinafter is in accordance with the test description in Chapter 2.1.11 of the OIE

Manual of Standards for Diagnostic Tests and Vaccines, fourth edition, 2000.

The recombinant VP7 protein has been used as antigen for AHS virus antibody determination with a high

index of sensitivity and specificity. Other advantages are that it is stable and not infective.

2.1. Test procedure

2.1.1. Solid phase

2.1.1.1. ELISA plates are coated with recombinant AHSV-4 VP7 diluted in

carbonate/bicarbonate buffer, pH 9,6. Incubate plates overnight at 4 °C.

2.1.1.2. Wash the plates five times with distilled water containing 0,01 % (v/v) Tween 20

(washing solution). Gently tap the plates onto absorbent material to remove any residual

wash.

2.1.1.3. Block the plates with phosphate buffered saline (PBS) + 5 % (w/v) skimmed

milk (Nestlé Dry Skim Milk TM ), 200 µl /well, for 1 hour at 37 °C.

2.1.1.4. Remove the blocking solution and gently tap the plates onto absorbent material.

2.1.2. Test samples

2.1.2.1. Serum samples to be tested, and positive and negative control sera, are diluted 1

in 25 in PBS + 5 % (w/v) skimmed milk + 0,05 % (v/v) Tween 20, 100 µl per well.

Incubate for 1 hour at 37 °C.

For titration, make a twofold dilution series from 1 in 25 (100 µl /well), one serum per

plate column, and do the same with positive and negative controls. Incubate for 1 hour at

37 °C.

2.1.2.2. Wash the plates as described in step 2.1.1.2.

2.1.3. Conjugate

2.1.3.1. Dispense 100 µl /well of horseradish-peroxidase (HRP) -conjugated anti-horse

gamma-globulin diluted in PBS + 5 % milk + 0,05 % Tween 20, pH 7,2. Incubate for 1

hour at 37 °C.

2.1.3.2. Wash the plates as described in step 2.1.1.2.

2.1.4. Cromogen/Substrate

2.1.4.1. Add 200 µl /well of chromogen/substrate solution (10 ml of 80,6 mM DMAB

(dimethyl aminobenzaldehyde) + 10 ml of 1,56 mM MBTH (3-methyl-2-benzo-thiazoline

hydrazone hydrochlorid) + 5 µl H2O2)

Colour development is stopped by adding 50 µl of 3N H2SO4 after approximately 5 to

10 minutes (before the negative control begins to be coloured).

Other chromogens such as ABTS (2,2'-Azino-bis-[3-ethylbenzothiazoline-6-sulphonic

acid]), TMB (tetramethyl benzidine), or OPD (ortho-phenyldiamine) can also be used.

2.1.4.2. Read the plates at 600 nm (or 620 nm).

2.2. Interpretation of the results

2.2.1. Calculate the cut-off value by adding 0,6 to the value of the negative control (0,6 is the

standard deviation derived with a group of 30 negative sera).

2.2.2. Test samples giving absorbance values lower than the cut-off are regarded as negative.

2.2.3. Test samples giving absorbance values greater than the cut-off + 0,15 are regarded as positive.

2.2.4. Test samples giving intermediate absorbance values are doubtful and a second technique must

be employed to confirm the result.

3. Blocking elisa for the detection of antibodies to african horse sickness virus

(AHSV) (prescribed test)

The blocking ELISA is designed to detect specific AHSV antibodies in sera from any susceptible species.

VP7 is the major, antigenic, viral protein of AHSV, and is conserved within the nine serotypes. Because the

monoclonal antibody (Mab) is also directed against the VP7, the assay will give a high level of sensitivity

and specificity. Further, the recombinant VP7 antigen is completely innocuous and therefore guarantees a

high degree of safety.

The principal of the test is the interruption of the reaction between the recombinant VP7, as the antigen

bound to the ELISA plate and the conjugated Mab specific for the VP7. Antibody in the test sera will block

the reaction between the antigen and the Mab resulting in a reduction in colour.

The test described hereinafter is carried out in the European Community Reference Laboratory for African

horse sickness in Algete, Spain.

3.1.1.2. Wash the plates five times with phosphate buffered saline (PBS) containing 0,05

% (v/v) Tween 20 (PBST).

3.1.1.3. Stabilise the plate by treatment with a stabilising solution (in order to allow long

term storage at 4 °C without loss of activity) and blot dry onto adsorbent material.

3.1.2. Test samples and controls

3.1.2.1. For screening

dilute test sera and controls 1 in 10 directly on the plate in PBST to give a final

volume 100 µl/well. Incubate for 1 hour at 37 °C.

3.1.2.2. For titration

prepare a twofold dilution series of test sera and positive controls (100 µl/well)

from 1 in 10 to 1 in 1 280 across eight wells. Negative control is tested at 1 in 10

dilution.

3.1.3. Conjugate

Add 50 µl /well of pre-diluted horseradish-peroxidase (HRP) -conjugated Mab (monoclonal

antibodies specific for VP7) to each well and mix gently to ensure homogeneity. Incubate for

30 minutes at 37 °C.

3.1.4. Wash the plates five times with PBST and blot dry as above.

3.1.5. Chromogen/Substrate

Add 100 µl /well of chromogen/substrate solution (1 ml of ABTS (2,2'-Azino-bis-[3-

ethylbenzothiazoline-6-sulphonic acid]) 5 mg/ml + 9 ml of substrate buffer (0,1 M Phosphate-

Citrate buffer of pH 4 containing 0,03 % H2O2] and incubate for 10 minutes at room

temperature. Colour development is stopped by adding 100 µl /well of 2 % (w/v) SDS

(sodium dodecyl sulphate).

3.1.6. Reading

Read at 405 nm in an ELISA reader.

3.2. Interpretation of the results

3.2.1. Assay validation

The test is valid when the optical density (OD) of negative control (NC) is higher than 1,0 and the

OD of positive control (PC) is lower than 0,2.

3.2.2. Cut-off calculation

Positive cut-off = NC – ((NC – PC)x 0,3)

Negative cut-off = NC – ((NC – PC)x 0,2)

Where, NC is the OD of the negative control and PC the OD of positive control.

3.2.3. Interpretation of results

Samples with OD lower than positive cut-off should be considered as positives to AHSV antibodies.
