Venereal infection of cattle
Infertility in female cattle
Found in glandular crypts of prepuce of bull with no clinical signs - carriers
Causes catarrhal inflammation in female genital tract
Endometritis prevents implantation until infection cleared and causes early embryonic death, occasionally sporadic abortion
May remain infertile for 3-5 months before immunity develops, which lasts 4-5 years
Effective immunity includes induction of IgA in the vagina and IgG in the uterus
Bacteria may persist in the vagina and be transmitted to bulls
Diagnosis:
- Fluorescent antibody test on genital discharges from bull/cow
- Vaginal mucus agglutination test
- ELISA to IgA antibodies in vaginal mucus after an abortion
- PCR for detection in semen
Treatment: dihydrostreptomycin intrauterine for cows and systemically or topically for bulls
Vaccination: bacterin in oil adjuvant

-''Campylobacter fetus'', has the subspecies [[Campylobacter fetus subspecies fetus|''fetus'']] and ''venerealis'', belonging to the genus [[Campylobacter species - Overview|''Campylobacter'']]. ''Campylobacter fetus subsp. venerealis'' causes '''venereal infection in cattle''' and '''infertility in female''' cattle.
+*Treatment: dihydrostreptomycin intrauterine for cows and systemically or topically for bulls
+*Vaccination: bacterin in oil adjuvant
-'''Bulls are carriers''' of the disease as they show no clinical signs but bacteria can be found in the glandular crypts of the bulls prepuce. ''Campylobacter fetus'' subsp.'' venerealis'' is therefore spread by coitus or rarely by artificial insemination. It causes catarrhal inflammation in the female genital tract, temporary infertility and prolonged oestrus cycle. [[Endometritis - Cattle|Endometritis]] prevents implantation until the infection is cleared and causes early embryonic death and occasionally sporadic abortion.
-The cow may remain infertile for 3-5 months before immunity develops, which then lasts 4-5 years. Effective immunity includes induction of [[IgA]] in the vagina and [[IgG]] in the uterus.
-The bacteria may persist in the vagina and be transmitted to bulls.
-==Diagnosis==
-A [[FAT|fluorescent antibody test]] on genital discharges from the bull or cow can be diagnostic. A vaginal mucus agglutination test can be done.
-An [[ELISA testing|ELISA]] to [[IgA]] antibodies in vaginal mucus after an abortion can be done in the cow, or PCR for detection in semen.
-==Treatment==
-Dihydrostreptomycin intrauterine for cows and systemically or topically for bulls.
-A vaccination of bacterin in oil adjuvant can also be done.
