SUMMARYPrevious investigations have shown that cross-contamination in a burn unit is mainly clothes-borne. New barrier garments have been designed and tried experimentally. The aim of the present study was to investigate the effects of different clothing routines on cross-contamination. In a long-term study, the rates and routes of colonizations withStaphylococcus aureus, Streptococcusgroups A, B, C, F, and G andPseudomonas aeruginosawere examined. The exogenous colonization rates were, withS. aureus77%, withStreptococcusspecies 52% and withPs. aeruginosa32%. The colonization rate withPs. aeruginosawas higher in patients with larger burns. Patients dispersedStreptococcusandPs. aeruginosaas well asS. aureusinto the air of their rooms in considerable amounts, but dispersers were not more important as sources of cross-colonization than non-dispersers. In comparison of clothing routines, there was no difference in overall colonization rates. The newly designed barrier garment that was made from apparently particle-tight material did not reduce the transfer of bacteria from patient to patient. A less rigid routine than that previously used did not increase the risk of cross-contamination. A thorough change of barrier dress after close contact nursing delayed the first exogenousS. aureuscolonization from day 6 to day 14 after admission. This routine might be recommended for clinical use. Otherwise, methods must be developed for adequate selection of materials intended for barrier garments.

Современная экономика диктует необходимость быстрой и эффективной окупаемости затрат, вложенных в производство продукции садоводства, что требует интенсификации отрасли. Одним из путей решения поставленных задач является закладка садов на клоновых подвоях, обеспечивающих высокое, стабильное плодоношение, с плодами отменных вкусовых качеств, подбор новых подвоев, приспособленных к условиям Крыма и не уступающих по комплексу хозяйственно-биологических свойств районированным в регионе. В статье освещены результаты многолетнего изучения 14 клоновых подвоев в сочетании с двумя сортами яблони. Определена сила роста изучаемых привойно-подвойных комбинаций в почвенно-климатических условиях Предгорного Крыма. Комбинации сортов Аскольда и Ренет Симиренко с подвоями ЕМ-IX, КД 4, КД 5 по показателям параметров кроны относятся к слаборослой группе. Деревья на К 104 по силе роста занимают положение промежуточное между ЕМ-IX и ММ-106, но имеют хорошо развитую корневую систему и компактную форму кроны. Выделенные комбинации рано вступают в плодоношение (на 2-3-й год). Средний урожай таких насаждений равен 24,4-30,6 т/га. Отобранные подвои обладают большим биологическим потенциалом и эффективными хозяйственно-биологическими свойствами, и представляют интерес для южного садоводства. Modern economy necessitates quick and effective return of costs invested in the horticultural production, which requires the intensification of the industry. One of the ways to solve the assigned tasks is to establish gardens on clonal rootstocks ensuring high and consistent fruiting with crops of excellent palatability traits, selection of new rootstocks adapted to the conditions of Crimea and not inferior in terms of the range of economic and biological properties to those released in the region. This paper highlights the results of long-term study of 14 clonal rootstocks in combinations with two apple varieties. The growth power of the studied scion-rootstock combinations in the soil and weather conditions of the Piedmont Crimea was determined. Combinations of ‘Ascolda’ and ‘Renet Simirenko’ varieties with rootstocks EM-IX, KD 4, and KD 5 in terms of crown parameter values belong to a dwarf group. Trees on K 104 are intermediate between EM-IX and MM-106 in terms of growth power, but have a well-developed root system and a compact crown shape. The above mentioned combinations enter into fruiting very early (on the 2nd-3d year). The average yield of such plantations is 24.4- 30.6 t/ha. The selected rootstocks are of great biological potential and effective economic and biological properties, so they are promising for southern horticulture.

Modern economy prescribes the necessity of rapid and efficient returns of costs invested in horticultural production. It requires an intensification of the industry. One of the ways to achieve this goal is to establish gardens on clonal rootstocks ensuring high and stable crop-bearing with fruits of excellent taste, selection of new rootstocks, adapted to the conditions of Crimea and not inferior in terms of the economical and biological properties to those already recognized in the region. The article highlights the results of a long-term study of 14 clonal rootstocks in combination with 2 apple varieties. We determined the power of growth of the grafting and rootstock pairs in the soil and weather conditions of the Piedmont Crimea. Combinations of ‘Ascold’ and ‘Renet Simirenko’ varieties with rootstocks EM - IX, KD 4, KD 5 in terms of crown parameters belong to a dwarf group. By the power of growth, the trees on K 104 are intermediate between EM - IX and MM - 106, but they have a well-developed root system and compact shape of the crown. The obtained combinations come into fruiting early (in the 2nd-3d year). The average yield of such plantations is 24.4-30.6 t / ha. The selected rootstocks have great biological potential and effective economical and biological properties proving to be promising for southern horticulture.
