Ten autoaggregating vaginal Lactobacillus strains (five of these strains were selected among isolates from sows' vaginal swabs and the other five among isolates from cows' vaginal swabs) were investigated for their ability to bind type Icollagen (Cn-I). All 10 autoaggregating strains in the range of A_570nm readings 0.118-1.806 bound to immobilised Cn-I (at concentration of 100 μg/ml) in wells of microtitre plates, however, Lactobacillus acidophilus SV31 was much more adherent than the rest of the tested strains. The influence of culture medium on Cn-I binding was confirmed only in 50% of the tested strains when agar-grown...

A total of 15 strains of Psychrobacter immobilis isolated from animal sources, e.g. cheese, fish and poultry, were tested. A commercial diagnostic kit NEFERMtest 24, conventional tests and determination of fatty acids were used for identification. By using the results of NEFERMtest 24 and numerical identification system TNW version 6.0 the identification was successful on the species level (46.7%) while the correct species identification by using conventional tests increased up to 86.7%. All 9 saccharolytic strains including 7 Czech isolates were identified in most cases on an excellent or very good level by both methods based on biochemical...

The aim of this paper was to register the domestic animals appearing in the iconography of Christian saints and to explain their association. The source of knowledge was literature dealing with hagiographies of saints, sacral iconography and liturgy along with visiting churches, monasteries and museums throughout Croatia. After research in sacral literature and works of art lasting several years, it was observed that the following domestic animals appear as accompanying about seventy Christian saints: bees, bull, camel, cow, dog, donkey, goose, dove, horse, lamb, pig, sheep, steer. Reasons and explanations of their association are most often in practical...

Factors affecting milk ejection and removal during milking and suckling of dairy cowsReview

Vet Med - Czech, 2001, 46(4):108-118 | DOI: 10.17221/7860-VETMED  

The release of oxytocin and milk ejection occurrence in response to teat stimulation are crucial for fast and complete milk removal during milking or suckling. The milk ejection reflex can be disturbed at central or peripheral level under different experimental and practical conditions. The central disturbance results in the lack or insufficient ejection of the alveolar milk into the cistern due to inhibited oxytocin release from pituitary into the blood circulation. The important role in the pathophysiological regulation of the inhibited release of oxytocin is played by an opioid system. Endogenous opioids have suppressive effects on oxytocin release...

Pasteurella haemolytica complex of Pasteurella sensu stricto as new genus Mannheimia: changes in taxonomyReview

G. Tefera, J. Smola

Vet Med - Czech, 2001, 46(4):119-124 | DOI: 10.17221/7864-VETMED  

The benefit and usefulness of the new results described by Angen et al. (1999) rest upon the necessity for revising the previous taxonomy of Pasteurellaceae by grouping microorganisms based on their phylogenetic relationships combined with phenotypic characters and the usefulness of molecular biological methods in determining the taxonomic structure based on genomic evidence with supplementary phenotypic data. According to authors cited the phenotypic character of each serotype, species and even genus was well defined by their morphology, growth requirements and metabolic activities. The genomic relationships of serotypes, species...
