Monthly report: Survellience Project SB4008 IFNg tests for Bovine tuberculosis - April 2019
Source: environment.data.gov.uk (2022-01-18)

Interferon-Gamma Testing for Bovine Tuberculosis - Monthly Reports from April 2016. These monthly reports summarise the gamma tests completed / reported during that calendar month. The report also summarises tests for the whole calendar year to the end of the current month.
While all effort is made to ensure the accuracy of the test data, small errors can occur and later corrected in subsequent reports. 

Cattle interferon-gamma (IFNg) tests (and test outcome) carried out between 1st Jan and 31st Dec 2009. Tests are listed by country (England, Wales, Scotland) and by Animal Health Office (AHDO) and the reason for the test. Reports contain test data for the month, the calendar year to date and total tests since rollout (23rd Oct 2006). 

Please note: this dataset consists of 12 monthly reports. Data for this report was compiled from field staff inputs and laboratory test information. Subsequent minor data amendments may have been made after the report was originally compiled, and these corrections would appear in the following month’s report. Each report was checked and deemed correct at the time of release. Attribution statement:

Monthly Report:
Surveillance Project
SB4008 IFNg tests for
bovine tuberculosis
(TC0651 and TC0751)
Number 152
Report Period 1st - 30th April 2019
Issued 08 May 2019

Operational notes on terminology, definitions, re-test and re-samples test
outcomes:
• “Samples” refers to an individual tube of blood taken from an individual animal which is
subsequently submitted for testing. It is generally assumed that the number of samples and
the number of animals are analogous as any duplicate sample blood tube from the same
animal will not be tested. However, minor discrepancies may occur where the same animal is
tested more than once due to a request for a resample or the animal is tested twice under
different categories (for example, as a PAR-RAPID and then as part of a PAR-HERD-S).
• “Submissions” refers to an individual batch or set of samples received for testing.
Submissions may comprise 1 or more samples (for example, if an entire herd is being tested it
is usually sent as 1 submission). It is generally assumed that the number of submissions and
the number of herds are analogous.
• Retests are samples where the first ELISA assay fails and the same sample is retested on a
new ELISA plate. Each sample can be retested only once. A retest is not a reportable test
outcome.
• Resamples are where a sample has been retested and failed a second time, so that the lab
requests a new sample. This is a reportable test outcome.
• Rejects are samples that are not tested by the lab for one of the following reasons: blood
collected into wrong type of vacutainer, samples that have not been maintained at the
appropriate temperature range (22±5C), unlabelled samples, broken or cracked tubes, blood
that is extensively clotted (small clots are OK), samples received after 4pm on the day after
sample collection. Such samples are reported separately in the tables and in figure 5.
• POS (pokeweed mitogen) is a sample positive control reagent which provides a measure of
the quality/viability of the blood sample. A POS fail (< 0.45 optical density reading) may
indicate compromised blood quality as a result of collection/transportation conditions or due
the animal having an unusually low/suppressed cellular immune response.
• NEG (no-antigen control) is a sample negative control which provides a measure of the
background antigen-independent IFN- responses. A NEG fail (> 0.3 optical density reading)
may indicate a laboratory procedures problem (normally resolved during re-test) or that an
animal has unusually high background levels of IFN-g.

Submission Reason
Explanation
Mandatory?
Possible Herd Slaughter
(PAR-HERD-S)
Parallel interferon-gamma blood testing of skin
test negative cattle to inform whole or partial
herd slaughters decisions
YES, if APHA are
contemplating a herd
slaughter
Persistent TB breakdowns
(OTF status withdrawn)
(PAR-P-CONF) N.B.
PAR-PERSIS from 1st April
2017
Parallel blood testing of skin test-negative cattle

resolve by repeated short-interval skin testing
and fulfill a minimum of biosecurity standards.
NO (APHA discretion)
Parallel - Low Incidence
(PAR-LOW-IN) N.B.
PAR-NEW-IN from 1st April
2017
Parallel blood testing to maximise the
probability of removing all infected cattle in a
new herd breakdown as soon as possible after
confirmation of TB.
YES in Area of Low
Incidence
Rapid Testing of twice IR's
(PAR-RAPID)
Parallel blood testing of two-times IRs identified
under the severe interpretation of the skin test
used in Wales.
YES (Wales only)
PAR-CUL-N
Parallel blood testing to maximise the
probability of removing all infected cattle in a
new breakdown as soon as possible after
confirmation of TB where herd is situated in
badger control areas of England that have
completed at least 2 effective culls.
YES (in eligible badger
control areas of England)
PAR-CUL-P
Parallel blood testing to maximise the
probability of removing all infected cattle in a
persistent confirmed breakdown where herd is
situated within badger control areas of England
that have completed at least 2 effective culls
NO (APHA discretion)
Parallel Other
(PAR-OTHER)
Other parallel blood testing not covered in any
of the other scenarios
NO (APHA discretion)
'NSR' Herds (SER-NSR)
Modified serial blood testing of individual skin
test reactors and/or IRs in unconfirmed TB
breakdown herds to clarify their infection status
where there is evidence of non-specific
sensitisation to bovine tuberculin (the
“non-specific reactor” procedure)
NO (APHA discretion)
Suspected Fraud
(SER-FRAUD)
Modified serial blood test of suspected
fraudulent reactors to the skin test (animals with
abnormal skin swellings), in confirmed or
unconfirmed TB incidents.
NO (APHA discretion to
firm up or rule out any
suspicion of fraud and
support any
investigations)
Serial Other
(SER-OTHER)
Serial test – other reasons
NO (APHA Discretion)
SER-FLEXI
Extended blood test to provide flexible test
readout in a confirmed M. bovis-infected herd
where Johne's (M. a. paratuberculosis) infection
or vaccination is suspected to be interferring
with M. bovis infection detection
NO (APHA discretion)

* Sufficient plasma supernatant is collected and stored following the overnight culture stage of the assay such that if the sample fails any of the QC criteria, it is
possible for the laboratory to ‘re-test’ the original sample. Depending on the outcome of a retest, a resample (if QC criteria fail to be met), a positive or a negative
result will be reported. Therefore, the total number of samples = the sum of positive, negative, resample and reject samples only.

* Sufficient plasma supernatant is collected and stored following the overnight culture stage of the assay such that if the sample fails any of the QC criteria, it is
possible for the laboratory to ‘re-test’ the original sample. Depending on the outcome of a retest, a resample (if QC criteria fail to be met), a positive or a negative
result will be reported. Therefore, the total number of samples = the sum of positive, negative, resample and reject samples only.

PAR-HERD-S: potential herd slaughter, PAR-P-CONF (PAR-PERSIS from 1 April 2017): persistent TB breakdown OTFW, PAR-LOW-IN (PAR-NEW-IN from 1 April 2017): parallel low incidence, PAR-RAPID: rapid testing
of twice IRs, PAR-CUL-N: new infection in cull area, PAR-CUL-P: persistent infection in cull area, PAR-OTHER: parallel other, SER-FLEXI: flexible extended test in confirmed herds with concurrent Johne’s
infection/vaccination, SER-NSR: serial non-specific reactor, SER-FRAUD: serial potential fraud, SER-OTHER: serial other
* Sufficient plasma supernatant is collected and stored following the overnight culture stage of the assay such that if the sample fails any of the QC criteria, it is
possible for the laboratory to ‘re-test’ the original sample. Depending on the outcome of a retest, a resample (if QC criteria fail to be met), a positive or a negative
result will be reported. Therefore, the total number of samples = the sum of positive, negative, resample and reject samples only.

*For test criteria please refer to Operational notes.
PAR-HERD-S: potential herd slaughter, PAR-P-CONF (PAR-PERSIS from 1 April 2017): persistent TB breakdown OTFW, PAR-LOW-IN (PAR-NEW-IN from 1 April 2017): parallel low incidence, PAR-RAPID: rapid testing
of twice IRs, PAR-CUL-N: new infection in cull area, PAR-CUL-P: persistent infection in cull area, PAR-OTHER: parallel other, SER-FLEXI: flexible extended test in confirmed herds with concurrent Johne’s
infection/vaccination, SER-NSR: serial non-specific reactor, SER-FRAUD: serial potential fraud, SER-OTHER: serial other
* Sufficient plasma supernatant is collected and stored following the overnight culture stage of the assay such that if the sample fails any of the QC criteria, it is
possible for the laboratory to ‘re-test’ the original sample. Depending on the outcome of a retest, a resample (if QC criteria fail to be met), a positive or a negative
result will be reported. Therefore, the total number of samples = the sum of positive, negative, resample and reject samples only.
