Faecal samples were investigated from 948 children hospitalized with the diagnose of acute intestinal infection. The authors studied the isolation and properties of a broad spectrum of microorganisms from children's faeces: Salmonella, Shigella, E. coli, S. aureus, rotaviruses, Klebsiella, Morganella, Proteus. As a result, laboratory criteria were formulated of diagnosing in children intestinal infection of staphylococcal etiology. 相似文献

Silurian rocks from borehole cores in the Baltic Basic were analyzed for Si, Al, Ti, Fe, Ca and Mg oxide content and chemical data were related to sedimentary environment, lithology and brachiopod community distribution. Evaluation of these relationships enables precise positioning of closely related communities within Boucot's (1975) brachiopod Benthic Assemblages. Preliminary attempts are made to evaluate climatic change based on Al/Ti oxide ratios. 相似文献

Two erythrocytic LDH variants have been found in the house mouse, Mus musculus. One, involving the presence and absence of the next to the slowest electrophoretically separable isozyme, is controlled by a regulatory locus which may be similar to Ldr-1 (Shows and Ruddle, 1968). The second appears to be indirectly controlled by the Hbb locus and may be attributed to the accumulation of a storage product in the lysates. Ldr-1 is polymorphic in natural populations of the house mouse. 相似文献

Genetic variability of the nontranscribed spacer (NTS) region within ribosomal DNA repeating units in the various subspecies of Mus musculus was determined. Mice belonging to several laboratory mouse strains were examined by means of Southern blot hybridization with a mouse ribosomal DNA probe. This probe encompasses the 3' end of the 28S ribosomal RNA (rRNA) gene and the following spacer. Restriction enzyme digestions of the liver DNAs from various wild mice revealed that each of the subspecies has a unique pattern in the spacer encompassing a distance approximately 10 kb downstream from the ribosomal gene. These restriction patterns permit the classification of mouse subspecies and also provide insights into the origin of the laboratory mouse strains. 相似文献

The production of toxins of the toxic shock syndrome and enterotoxins by S. aureus of clinical origin was studied by means of commercial standard antisera and standard toxins. The study revealed that among 511 strains isolated in Russia toxigenic ones constituted 41%, and among 592 strains isolated in Czechia toxigenic ones constituted 63%. The capacity for producing toxins may be used as an epidemiological marker. 相似文献
