Infectious Abortion Flashcards
Which of the following refers to the death of a zygote or embryo?
Early embryonic death
- Death of fetus after the 20th week of pregnancy
- Delivery of a fully formed dead neonate
Stillbirth
Expulsion of the products of conception from the uterus before the fetus is viable
Abortion
- Desiccation of a dead fetus in utero
- Bacterial infection CANNOT be present
- Intact corpus luteum must be present
Mummification
Fetal death in presence of in-utero bacterial infection and inflammation
Maceration
The tissue that is most likely to resist degradation in fetal maceration is:
Bone
What is the highest percentage of fetal loss that takes place in any species?
Embryonic Death
The most common and important cause is lethal chromosomal abnormalities but infectious or toxic causes can also be involved.
This is describing:
Embryonic death
- Dead fetus is retained in the uterus due to a functional CL.
- Fetal skin must be mature enough to resist autolysis.
Mummification
What is a reason for low diagnostic rates in abortion cases?
Advanced autolysis makes lesion identification difficult
(T/F) 90% of cases in which the cause are determined are infectious
True
(T/F) Abortion outbreaks are easier to diagnose than sporadic abortions
True
(T/F) Abortions due to non-infectious causes are easier to diagnose than abortions due to infectious causes
False
list the reasons for Low Diagnostic Rates:
- Abortion results from an event that happened weeks to months earlier.
- Advanced autolysis makes lesion identification difficult.
- The placenta is not available for examination.
- Toxic, nutritional, hormonal, and genetic causes of abortion are often not detectable in fetal tissues
What organs are you sampling for culture in fetal sampling?
- Placenta
- STOMACH CONTENTS
- lung
- kidney
- liver
- thoracic fluid.
