Stillbirths and birth defects in sheep, cattle and goats; Congenital malformations in newborn sheep, goats and calves are the most obvious symptoms. In many cases, the dam (female parent) apparently has not presented signs of illness. These cases have occurred from December 2011, especially in sheep.
Chlamydia abortus is endemic among ruminants such as cows and sheep and has been associated with abortion in a horse, a rabbit, guinea pigs, mice, pigs and humans. Infected females shed bacteria near the time of ovulation, so C. abortus is transmitted orally and sexually among mammals.
VUE occurs in the term placenta, in the late third trimester of pregnancy. Infectious villitis occurs at the early-third to late-second trimester of the pregnancy. Infectious villitis involves a greater part of the placenta (umbilical cord, chorionic plate, membranes) compared to VUE (terminal and stem villi). Histologically VUE is ...
Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1]
Generally, once infected, treatment options are limited. [4] Injecting the lesion with cidofovir or applying imiquimod has been studied. [4] However, it is sometimes required to excise the pustules.. [4] The vaccine used in sheep to prevent orf is live and has been known to cause disease in humans. [4] The disease is endemic in livestock herds ...
[28] [29] According to the World Health Organization (WHO), 22 million unsafe abortions occur each year globally. [30] Studies have shown that women appear to have low knowledge on abortion regulations and laws in their countries. In other words, the lack of knowledge on legal status of abortion can cause women to seek abortion services that ...
Histopathology of placenta with increased syncytial knotting of chorionic villi, with two knots pointed out. The following characteristics of placentas have been said to be associated with placental insufficiency, however all of them occur in normal healthy placentas and full term healthy births, so none of them can be used to accurately diagnose placental insufficiency: [citation needed]
In endemic areas morbidity is around 70-90% while SPV mortality is 5-10%, with its peak two weeks after the appearance of lesions. [6] [7] [4] [8] It is the cell mediated immune response which eliminates the infection. [8] There have only been two reported cases of zoonotic transmission which result in a mild localized reaction limited to the ...
