Montana Brucellosis FY23 and FY24 YTD Comparison Tests
The graph above shows a comparison of the number of animals tested for Brucellosis in FY23 and FY24 through the Q3, with data for each month, breaking down the total number of tests by category such as Ranch, Market, Epidemiological (Epi), Slaughter, Certified Semen Service (CSS), and Other. Generally, the trend in test numbers is consistent from year to year, although test numbers for September 2023 were higher. Test numbers follow the seasonality of the cattle production cycle and are useful in predicting program expenditures.
Designated Surveillance Area (DSA) Reimbursements for Testing & Vaccination Q2
Department reimbursement for testing has helped to minimize DSA producer costs for program compliance while protecting the remainder of the state from unnecessary testing due to loss of Brucellosis class status or trading partner confidence. The table above reflects reimbursements for Brucellosis testing across two groups: veterinarians and producers, for the second quarter of FY24 and FY24 year to date. This data highlights the financial aspect of disease management and control efforts within the livestock industry. Funding for Montana’s brucellosis program comes from Montana General Fund and cooperative agreement funding from USDA Veterinary Services (VS).
The table above summarizes the testing for Brucella canis (B. canis) conducted in Q3. It is noted that these totals may include re-tests, as well as tests conducted on canines that do not reside in Montana full-time, suggesting that the data encompasses a wider population than just the resident canines of Montana. This context indicates ongoing surveillance efforts for B. canis and provides insight into the prevalence of the disease within the tested canine population over this quarterly period.
The graph above shows B. canis testing conducted in Q3. The fiscal year-to-date (FY24 Total YTD) data is also provided, showing 518 negative and 68 positive tests, with an overall percent positive rate of 11.60%. Data shows a significant incidence of B. canis that warrants attention for public health and veterinary intervention.
The graph above compares the number of B. canis tests conducted in FY23 and FY24 up to the current quarter. FY23 testing shows a general increase in the number of tests conducted, with a notable peak in February 2024.
Montana Brucella canis (B. canis) Testing by County FY24
The map above illustrates the distribution of total B. canis screening tests conducted by county in FY24 Q3. The map provides a visual representation of testing efforts and may reflect a region’s focus on monitoring and controlling the spread of B. canis.
The graph above demonstrates the significant number of tests that are being performed through Montana animal shelters. Shelters conducted 196 tests compared to owned animal tests at 101. In other words, shelters accounted for 51.5% of the testing performed in Q3. Which is lower than the report from Q2 when shelters represented 64.6% of the testing performed. The Department of Livestock recommends that shelter animals that have one of the designated risk factors be tested prior to adoption.
Historical Montana Brucella Canis (B. canis) Testing FY17-FY23
The graph above shows a steady increase in both the total number of tests conducted and the number of positive results over FY17-FY23. The percentage of positive results has also risen year over year, with a notable jump FY21 after DOL requested increased surveillance due to concerns over increasing numbers of symptomatic and positive dogs. This trend continued in FY22 and FY23 thanks to support for heightened surveillance by the MT veterinary community. With the enhanced detection efforts, we have also noticed a continued increase in the percent positive rate.
The graph above displays a bar chart summarizing the total number of Johne's disease tests conducted in Q3. This representation highlights the monthly fluctuations in testing volume and the distribution of test results across the quarter, which is essential for monitoring the prevalence and control of Johne's disease in the livestock population.
The graph above is a horizontal bar chart showing the total number of Johne's disease tests conducted by county in Q3.
The chart above presents the annual number of Johne's disease tests conducted from FY18 to FY23. The overall number of tests has increased significantly over these years, suggesting enhanced testing efforts, and rising awareness of the disease.
The table below presents a detailed Rabies Test Summary for various animal species during Q3.
The map above shows the distribution of positive rabies cases across various counties in FY24 YTD. It illustrates the geographic spread of the disease with varying numbers indicated in each affected county. The visualization highlights areas with higher instances of rabies, suggesting regions where public health and veterinary services may need to focus their efforts on control and prevention measures.
The graph above is a bar chart depicting the number of trichomoniasis tests conducted in Q3. The number of tests increased significantly in March by 1,723 tests.
The map above illustrates the distribution of Bovine Trichomoniasis tests across various counties in Q3. Yellowstone county contains several Certified Semen Services facilities which conduct routine testing for trichomoniasis.
The map above displays the number of Trichomoniasis tests conducted by county in FY24 YTD.
The following table outlines the Foreign Animal Disease (FAD) investigations carried out in Q3 in various counties. All cases in Q3 were negative.
The table below shows testing for other reportable diseases in Montana for FY2024 Quarter 3. Please note, positive test results may not be confirmation of disease depending on the type of test conducted.
The table below shows testing for other reportable diseases in Montana for FY 2024 Year-to-Date. Please note, positive test results may not be confirmation of disease depending on the type of test conducted.
