[Cerebral hemodynamics in fetuses and newborns developing with impaired uterine and fetoplacental blood circulation].

By means of dopplerometry there were examined the blood flows in uterine arteries, funic arteries, internal carotid arteries of fetuses of 34 women in III trimester of a pregnancy with a threat of a premature birth. Cerebral blood flow in newborns was estimated on the 1-st and the 5-th days of life in anterior and middle cerebral arteries. Control group included 20 women with the physiologic pregnancies and their 20 newborns.

[Drug resistance of coagulase-negative staphylococci of animal origin depending on the source of the isolation and species classification of the strains].

Drug resistance of 271 strains of coagulase negative staphylococci isolated mainly from the upper respiratory tract and skin of healthy animals (cows, sheep, swine, hen, monkey, mink, sable and fox) was studied. Benzylpenicillin, streptomycin, tetracycline, chloramphenicol, erythromycin, oleandomycin, neomycin, monomycin, kanamycin and novobiocin and heavy metal salts, such as mercurous chloride and cadmium sulfate were used in the study. Unlike coagulase positive staphylococci isolated from the same sources, the coagulase negative strains were more frequently resistant to novobiocin (a specific feature of a number of the strains) and tetracycline and much less frequently resistant to benzylpenicillin and streptomycin.

[Phage typing of the coagulase-positive staphylococci isolated from various species of animals].

More than 200 coagulase-positive strains of animal origin have been studied by means of Staphylococcus aureus typing phages, belonging to two international sets and intended for typing staphylococci isolated from large cattle and humans, and experimental "chicken" phage A 1591. Among S. aureus strains the cultures isolated from swine, cows, chickens, and belonging to biotypes B1, C1, B2, respectively, have been mostly (in 78.

[Species characteristics of coagulase-negative staphylococci of animal origin].

The specific identification of 271 strains of coagulase-negative staphylococci isolated from different animals (cows, sheep, swine, hens, monkeys, minks, sables, foxes, etc.) was carried out according to the scheme of Akatov--Devriese. Species could be determined in 77.
