Normal Pluriparous Uterus.
Normal, nongravid, pluriparous, bicornuate buffalo uterus. Note the rugae on the horns, indicating pluriparity.
Vale WG (1987)
Normal Anestrous Uterus.
Normal, nongravid, anestrous, bubaline uterus. Note the rugae on the horns, indicating pluriparity. Both ovaries are inactive.
Vale WG (1987)
Endometrium.
Prominent normal caruncles in a relatively recent postpartum buffalo.
Vale WG (1987)
70-day Conceptus.
A gravid uterus has been opened to show a ~70-day conceptus (fetus plus membranes). Note also the caruncles in the endometrium and the cotyledons on the chorion.
Vale WG (1987)
Epithelial Plaques.
Epithelial plaques on the fetal side of the amniotic membrane. Their significance is unknown but they are sometimes confused with (fungal) lesions on the membranes after an abortion.
Vale WG (1987)
Allantoic Calculus.
Allantoic calculi are acellular concretions that float freely in the allantoic fluid. They are a source of curiosity at the time of delivery. In the bovine they are called bovomanes, in the equine hippomanes. Analogously, they should be called bubomanes or bubalomanes in Bubalus bubalis.
Vale WG (1987)
Metritis.
A purulent vaginal discharge is indicative of metritis and / or vaginitis.
Vale WG (1987)
Purulent Vaginal Discharge.
Metritis. The cervix is open allowing a vaginal discharge of pus and mucus.
Vale WG (2007)
Chronic Pyometra.
The uterus is filled with pus, while the cervix is closed. The ipsilateral corpus luteum is retained and keeps the buffalo from cycling (anestrus).
Vale WG (2007)
Pyometra.
With a closed cervix, a moderate amount of pus is trapped in the uterus, and the buffalo does not cycle due to retention of the corpus luteum. There is no evidence of discharge of pus into the vagina.
Vale WG (2007)
Uterine Adhesions.
Multiple old spiderweb - like adhesions of the uterus. They do not necessarily interfere with subsequent conception (unless they block the oviduct), but may lead to trauma as the uterus expands during pregnancy.
Vale WG (2007)
Uterus Unicornis.
Segmental aplasia: the right horn is absent. The single left horn is gravid.
Vale WG (2007)
Gravid Uterus Unicornis.
Segmental aplasia: the right horn is absent. The single left horn is gravid with a 55 to 60 day conceptus. Note the caruncles in the opened uterine horn, and the cotyledons on the chorionic membrane.
