Sažetak
The reproductive form of Haemophilic infection caused by a microorganism
Histophilus somni (Haemophilus somnus) is in our conditions practically unknown
and undiscovered disease of cow reproductive organs. The aim of this work was
based on experimental work to provide a comprehensive view on the pathohistological
and submicroscopic changes in the uterus of 60 cows, serological
positive, crossbreeds Slovenské strakaté x Holstein, aged 3.5 – 4.5 years,
serological positive, which were up to 90 days after the parturition sterile. After the
hormonal control of the oestrus cycle (PGF2α-Oestrophan SPOFA) the cows were
inseminated and the non-gravid cows later killed. The reproductive organs of killed
animals were pathologically – anatomically dissected with following histological and
sub-microscopic study of uterus and cervix tissue. At the beginning of the experiment
no clinical changes of the reproductive organs of group 1 animals with the titer of
antibodies 1:25-100 were diagnosed and in group 3 with the titer 1:25. At an
examination before killing were examined endometritis (EM) of grade II. and vaginitis
with vestibulitis in these groups. At the rest of animals appeared in every level of the
titer of antibodies of EM II. and EM III. EM I. were not clinically diagnosed. Dissecting
examination determined EM catarrhalis and cervicis catarrhalis in all groups. The
histological examination pointed to EM catarrhalis chronica, EM interstitialis chronica,
EM fibrousis and cervicis catarrhalis chronica. The leucocytes gained from a uterus
lavage were in a comparison with stroma leucocytes mostly polynuclear (neutrophils)
and in smaller amount small forms of lymfocytes. At long-term sterility of cows,
because of possible H. somnus infection, we regard as priority the serodiagnostics at
which is taken into consideration any level of the titer of antibodies.
