spon·ta·ne·ous abortion (spn-tn-s)

n.

A naturally occurring termination of a pregnancy. Also called miscarriage.

---

spontaneous abortion,

a termination of pregnancy before the twentieth week of gestation as a result of abnormalities of the conceptus or maternal environment. Up to 30% of pregnancies may end as spontaneous abortions, many caused by blighted ova that have congenital defects incompatible with life. Also called miscarriage. Compare induced abortion.

abortion

premature expulsion from the uterus of the products of conception; termination of pregnancy before the fetus is viable.

---

complete abortion

complete expulsion of all the products of conception.

early abortion

abortion within the first third of pregnancy.

epizootic bovine abortion

characterized by serious fetal disease followed by abortion. Endemic in California's coastal range and in the foothill region of the Sierra Nevada, USA. Necropsy findings in the fetus are diagnostic; they include profuse petechiation and severe granulomatous hepatitis. Cause appears to be a novel deltaproteobacterium closely related to members of the order Myxococcales. Transmitted by the tick, Ornithodoros coriaceus. Called also foothill abortion.

habitual abortion

spontaneous abortion occurring in three or more successive pregnancies.

incomplete abortion

abortion in which parts of the products of conception are retained in the uterus.

induced abortion

abortion procured by the veterinarian to eliminate a misalliance, to reduce wastage in animals in a feedlot, to encourage commencement of lactation earlier than would otherwise occur. In cattle manipulation through the rectal wall is a possible way of destroying the viability of the fetus. Induction by the administration of prostaglandins or corticosteroids is more usual. See also pregnancy termination.

infectious abortion

the common causes in the various species are:

cattle

Brucella abortus (brucellosis); Campylobacter fetus subsp. venerealis (vibriosis); Campylobacter fetus subsp. fetus; Leptospira pomona, L. hardjo (leptospirosis); Listeria monocytogenes (listeriosis); Arcanobacterium pyogenes; Aspergillus, Absidia and Mucor spp. (fungal abortion); bovine virus diarrhea virus; infectious bovine rhinotracheitis herpesvirus; Chlamydophila abortus; a deltaproteobacterium (epizootic bovine abortion); Coxiella burnetii (Q fever), Neospora caninum.

sheep and goats

Campylobacter fetus subsp. fetus (vibriosis); Campylobacter jejuni; Chlamydophila abortus (enzootic abortion of ewes); Listeria monocytogenes (listeriosis); Salmonella abortus-ovis; Brucella melitensis; Toxoplasma gondii (toxoplasmosis); Brucella ovis (limited occurrence); bluetongue virus; border disease.

horse

Streptococcus equi subsp zooepidemicus; Actinobacillus equuli, A. equisimilis; Rhodococcus equi; leptospirosis, most commonly the pomona serogroup and less frequently serovar grippotyphosa; equine herpesvirus (EHV1); equine viral arteritis (EVA); equine arteritis; Potomac horse fever; and in the USA the mare reproductive loss syndrome associated with ingestion of the Eastern tent caterpillar Malacosoma americanum.

pig

Leptospira pomona, L. grippotyphosa, L. canicola, L. icterohaemorrhagiae (leptospirosis); Erysipelothrix rhusiopathiae (erysipelas); porcine reproductive respiratory syndrome (PRRS) virus; parvovirus; porcine circovirus 2; Aujesky's disease; classical swine fever; and African swine fever.

dog and cat

Brucella canis, feline leukemia virus, feline herpesvirus.

missed abortion

retention of a dead embryo or fetus for more than 1 to 2 weeks.

pine needle abortion

a late-term abortion with retained fetal membranes in cattle caused by ingestion of isocupressic acid in the needles of Pinus spp., commonly P. ponderosa, but also P. jeffryi, P. contorta and Juniperus scopulorum and J. communis. Nutrient deficiency and tree management practices may promote ingestion off the ground as cattle graze through while eating early growing spring grass.

abortion rate

number of abortions as a percentage of the cows in the herd which were diagnosed pregnant in early pregnancy; the target is <2% but rates commonly approach 8% in dairy cattle and 5% in beef cattle.

septic abortion

abortion associated with serious infection of the uterus leading to generalized infection.

spontaneous abortion

abortion occurring naturally. See also spontaneous abortion.

abortion storm

a cluster of abortions occurring at about the same time or in rapid sequence within a group of pregnant females. See also equine viral abortion.

therapeutic abortion

abortion induced by a veterinarian for medical or other health reasons.

---

spontaneous

having no apparent external cause.

---

spontaneous abortion

most animal abortions are spontaneous in contradistinction to the surgically and medically procured abortions of humans. See also mismating, parturition induction.

avian spontaneous cardiomyopathy

an idiopathic disease of 1 to 4 week old turkey poults causing sudden death or a brief period of dyspnea; the heart is visibly dilated.

spontaneous internal hemorrhage

causes sudden death in most cases; causes include cardiac tamponade, aortic or atrial rupture, splenic rupture.

spontaneous pulmonary arteriopathy

see aelurostrongylus.

spontaneous regression

when diseases resolve themselves without outside assistance.

spontaneous virus encephalitis

so called because the disease appears without the subject animal coming in contact with a known encephalitogenic agent. In most instances the occurrence is eventually explained by the presence of a hitherto unknown virus.

spontaneous abortion

Miscarriage, natural abortion Obstetrics A pregnancy ending in spontaneous loss of the embryo or fetus before 20 wks of gestation. See Abortion.

Patient discussion about spontaneous abortion.

Q. I had a miscarriage 2 years back when I was obese.Can anyone guide? I had a miscarriage 2 years back when I was obese. But I am trying again after getting in to good shape and I am eating cautiously to ensure balanced diet. Will there by any problem in my delivery because of miscarriage? Can anyone guide?

A. It is quite a normal doubt because you already had miscarriage. The most important thing that you may have to do is to reveal your past history to your Gynecologist and seek their suggestion and assistance. I heard cases where people consume baby aspirin to prevent miscarriages. But I am not sure of how that medicine works with miscarriages. Be confident and follow good diet as you have been doing now and go for regular check-ups and try to know more information to better take care of you. I am strongly against self-medication and I shall suggest you to take meds with doctors advice.
