FOP 5 Cats and Dogs notes + presentation Flashcards
The rate of stillbirth in cats
about 7%
most common infectious cause of abortion in dogs
Streptococcus canis, an opportunistic pathogen
-Salmonella spp is often overlooked.
preferred submission sample to lab for abortion investigation of dog and cat
Submission of maternal serum and whole fetuses and placentae is preferred. If this is not feasible, a complete set of tissues for histopathology, bacteriology, mycoplasmology and virology should be collected. Specific requirements can be obtained from each laboratory.
carnivore placenta type and how nutrients are transferred
zonary
-center (labrynth) responsible for nutrient transfer and waste expulsion
-edge (hematoma) transfer of some immunoglobulins and some other nutrients - trophoblasts phagocytose blood to get this
how long does the canine CL last? what happens if a puppy dies at 30 days?
CL will last the full 63 day gestation period
-if puppy dies at 30d will undergo autolysis
how should we sample the carnivore placenta? where do many pathogens like to hang out?
-labrynth, marginal hematoma,..
-must cut across to get all areas
-many pathogens in the marginal hematoma, esp. bacteria
what can you expect in terms of mortality and causes when investigating FOP in dogs?
-up to 20% mortality
=6.8% abortion
=7.4% stillbirth
litter size of cats
4.6
birth weight of cat
93.5g
stillbirth and perinatal % for cats
stillbirth 7.2%
perninatal mortality 9.1% (to 8 weeks)
