Monthly report: Surveillance Project SB4008 IFNg Tests for Bovine Tuberculosis - June 2022
Source: environment.data.gov.uk (2023-01-25)

Interferon-Gamma Testing for Bovine Tuberculosis - Monthly Reports from January 2022. 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 (TC0651 and
TC0751) & Antibody
(TC0077) tests for bovine
tuberculosis
Number 190
Report Period 1st - 30th June 2022
Issued 10 July 2022

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.

SER-FRAUD: serial potential fraud, SER-OTHER: serial other, PAR-CHR: chronic breakdown herds - where VL reactors are disclosed at a 3rd or subsequent SI test, or SLH case after a 2nd or subsequent SI test
* 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.

Table 2b. Summary by County for 2022
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, PAR-CHR: chronic breakdown herds - where VL reactors are disclosed at a 3rd or subsequent SI test, or SLH case after a 2nd or subsequent SI test
* 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, PAR-CHR: chronic breakdown herds - where VL reactors are disclosed at a 3rd or subsequent SI test, or SLH case after a 2nd or subsequent SI test
* 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, PAR-CHR: chronic breakdown herds - where VL reactors are disclosed at a 3rd or subsequent SI test, or SLH case after a 2nd or subsequent SI test
* 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.

Table 5a. Summary of PM and culture results for IFNg positive animals.
Please note: “Wrong Eartags” – this column represents those samples in the laboratory information management system (LIMS) for which there is not a matching ear tag in the Cattle TB
Data dataset (SAM) at the time of monthly report trawling. Most resolve in subsequent monthly reports as the field data is added to SAM.
