1 Diseases of Concern: BVD and Trichomoniasis Robert Mortimer, DVM Russell Daly, DVM Colorado State University South Dakota State University

2 The Epidemiologic Triad Host Management Agent Environment

3 Trichomoniasis From Had over 50 positive herds in Colorado

4

5 Pregnancy rate Weaning weight Culling rate Replacement Rate Labor Veterinary Costs Trichomoniasis Economic Aspects

6 Trichomoniasis: ECONOMIC SIGNIFICANCE Calving Rate Difference 18.7% Primary Infection 90 days lost Secondary Infection 30 days lost Reinfection Rate 50%+ within 9 months Clark and Duffey. Aust. Vet J. 1983

7 Typical History Pregnancy Rates may be decreased by10-50% Function of size of herd, length of breeding season, time of pregnancy diagnosis Increased losses of pregnancy Usually with additional information it is determined that the disease actually entered the herd a year ahead of owner concern for a problem

8

9 Herd Problem 2 Oper. Nonaffected cattle H Affected Cattle 2 Ops. 3 Operations Large Operation with put together cattle

10 Trichomoniasis Bull Pathogenesis Not affected by the disease Primary vectors Mechanical transmission Permanent carriers Age related

11 Organism Protozoa Trichomonas foetus Transmission is sexual only

12 Female Possibilities Breeding Not infected; Get pregnant; normal calving Infected, not pregnant, mount immunity finally Get pregnant Breeding Breeding Get pregnant, lose pregnancy, develop pyometra, Mount immunity, Ultimately rebreed and get pregnant Calving Infected, carry throughout pregnancy infected for up to 60 d + postpartum

13 Female Risk Factors Most cows will clear themselves of the infection within 120 days but not all. Some cows can carry through pregnancy and be infective for 60 days pp

14 Trichomoniasis Diagnosis Preputial samples from bulls Cervical vagina mucus from infected cows Pyometra fluid from infected cows # 6- Absolute weakness is sampling technique

15 Diagnostic Methods Culture in tube or Pouch of Diamonds Media PCR Test

16 Diagnostic Challenges Age of bull Number of bulls Period of Sexual Rest

17 Number of bulls <10 bulls bulls >30 bulls Three test 2 tests 1 test Once diagnosis been made in the herd we test until we have at least 3 negative Tests

18 How much sexual rest? Bull Age No Rest day >85 days >100 days 1-2 year /46 0/46 0/46 3 year 1/39 2.5% 4 year 6/ % 5+ Year 5/ % 3/ % 1/ % 2/9 22.2% 8/43 0/ % 3/15 0/ % 0/7 0/7

19 Regulatory Programs States w/programs AZ, CO, NM, NV, ID, UT, WY, NE, SD, ND, CA Weaknesses Period of sexual rest # tests required May not cover female at all. Don t rely on state programs to keep you free from the disease. Develop and maintain your own Biosecurity program

20 Prevention and Control by Management

21 TREATMENT In the United States there are no drugs approved to treat bovine trichomoniasis in either bulls of cows

22 Control by Management Only virgin animals or animals free of exposure enter noninfected herd Allow ample time after calving before bull exposure Artificial Insemination Reputable source

23 Control by Management Depopulation Best if only few cows pregnant Partial depopulation almost always used

24 Grazing Associations Control Can come ONLY IF RULES are established and followed by all involved

25 Grazing Associations Control Rules Screen all bulls Use only bulls < 4 years ONLY cows that calved and virgin heifers allowed on range

26 Grazing Associations Special Problems If any breeding done before association grazing SAME RULES MUST APPLY or use A.I.

27 Lease Bulls Rules All bulls tested REGARDLESS OF AGE 3 negative tests

28 What about vaccination? Vaccine for cow use only Vaccine will not prevent infection but may decrease severity Last resort option

29 Management Issues

30 What about BVD?

31 Etiological Agents BVD Pestivirus Virus Worldwide distribution Estimate serum antibody prevalence 50-90% in cattle

32 Cytopathic (CP) Expression of p 80/N53 in BVD infected cells Correlates with induction of cytopathic changes in cells Donis & Dubovi, Virology 158:168, 1987 Cell Killing BVDV - 2 Phenotypes (Lab Characteristics) Noncytopathic (NCP) p 80/N53 is absent Considered the standard virus Accounts for >90% of infections Cause of persistent infections Dubovi, Comp. Imm. Inf. Dis. 15:155, 1992 Non Cell Killing

33 What causes a PI calf? Acute infectionpregnant female exposed to NCP BVDV 93% Persistently infected female giving birth 7% (Wittum, et al, Prev Vet Med 49 (2001) 83-94)

34 FETAL BVDV INFECTION infertility repeat breeding DURING GESTATION congenital defects immune response d 0 d 58 d 90 d 125 d 150 d 283 persistent infection abortion, weak or stillbirth

35 What about the bull? KNOWN: PI possibility Testes immunologically protected site BVDV shed semen Viral transmission and Infection can occur Can this result in development of a PI calf? Rare! Single study, frozen semen from a known PI bull used in 12 susceptible heifers resulted in all being pregnant, all infected, and 1 of the 12 was a PI calf. Meyling and Jensen. Veterinary Microbiology 17: What does this mean relative to natural service???

36 Beef Cow Herds Many animals in same stage of reproductive cycle especially stage of gestation Herd usually handled as a group

37 TAKE HOME MESSAGE! All herds should have monitoring/surveillance plan Plan should be put in place for monitoring herd additions In high risk herds, have a PI eradication plan

38 Beef Cattle - Prebreeding Test of Calves, Bulls, Cattle without Calves Negative Positive Retain in Herd Adapted from: Kelling,et al,the Bov Pract, 34:1 (2000) Calves Remove Positive Calves and Dams from Herd Prebreeding Bulls and Cattle without Calves Sell for Slaughter

39 Remove Positive Calves and Dams from Herd Prebreeding Sell positive calves for slaughter Positive Cow - PI calf product of PI cow Test Dams Negative Cow - PI calf from acute infection Adapted from: Kelling,et al,the Bov Pract, 34:1 (2000) Sell for slaughter Only cow may return to herd

40 BVD Vaccination May be prevented with well planned vaccination program Look at fetal protection information (not 100%)
