Abstract

Gravidnost u mačaka traje od 63 do 65 dana. Mačke su inducirani ovulatori te se
otpuštanje luteinizirajućeg hormona i posljedična ovulacija događaju potaknute koitusom.
Različiti poremećaji tijekom gravidnosti mogu uzrokovati ranu embrionalnu smrtnost i
resorpciju, fetalnu smrt i pobačaj te mrtvorođenje. Većina pobačaja infektivne je etiologije.
Bakterijske infekcije rijetko možemo sa sigurnošću potvrditi kao abortivne uzročnike, suprotno
tome retroviruse poput virusa mačje leukemije i virusa mačje imunodeficijencije te parvovirusa
često susrećemo pri dijagnostici pobačaja. Gubitci uzrokovani parazitom Toxoplasma gondii,
rezultat su sustavne bolesti majke. Nezrelost novorođenčadi pri porođaju doprinosi velikim
gubitcima tijekom neonatalnog razdoblja. Bakterije poput Staphylococcus spp., Streptococcus
spp., Escherichia coli i Salmonella spp., i parazit Toxocara cati samo su neki od uzročnika koji
predstavljaju značajan problem u neonatalnih mačića. Pri dijagnostici uzroka prekida
gravidnosti kod životinja, posteljica sadrži ključne tragove i dokaze. Značajan izazov za uspjeh
dijagnostike je vrijeme koje je proteklo između prikupljanja uzoraka, obrade i slanja u
laboratorije. Kako se taj interval povećava, tkiva se podvrgavaju autolizi, a uzročnici mogu
postati zahtjevniji ili nemogući za uzgoj. Kako bi se prevladali ovi problemi, veterinari se potiču
da provedu temeljitu razudbe, brzo prikupe i obrade uzorke i koriste posebne medije za
transport.

Abstract (english)

A cat's pregnancy lasts 63 to 65 days. Cat is an induced ovulator and the release of
luteinizing hormone and the subsequent ovulation occur triggered by coitus. Disturbances in
various aspects of the pregnancy can cause early embryonic mortality and resorption, fetal death
and abortion, and stillbirth. Most abortions are of infectious etiology. Bacterial infections can
rarely be confirmed with certainty as the cause of abortion, on the contrary, retroviruses such
as feline leukemia virus, feline immunodeficiency virus and the parvovirus are often
encountered in the diagnosis of abortion. Losses caused by the parasite Toxoplasma gondii are
the result of a systemic disease of the mother. Physiological aspects of newborn immaturity
contribute to heavy losses during the neonatal period. Bacteria such as Staphylococcus spp.,
Streptococcus spp., Escherichia coli, Salmonella spp. and the parasite Toxocara cati are just
some of the causative agents that represent a significant problem in neonatal kittens. When
diagnosing the cause of pregnancy loss in animals, the placenta contains key clues and evidence.
A significant challenge for the success of diagnostics is the time that has passed between sample
collection, processing and sending to diagnostic centers. As this interval increases, tissues
undergo autolysis, and pathogens may become more demanding or impossible to culture. In
order to overcome these problems, veterinarians are encouraged to conduct a thorough
necropsy, rapidly collect and process specimens, and use special transport media.
