| hemolysin of myxococcus fulvus nk 35 i. production and isolation. | myxococcus fulvus nk 35 has been shown to produce a soluble hemolysin which lysed rabbit, human, horse, and sheep erythrocytes. a medium (varghese's medium) was devised in which a maximum of hemolysin was produced in 6 days at 28 degrees c under static conditions. the lysin was precipitated by complete saturation of the culture filtrate with ammonium sulphate, followed by dialysis against saline. other enzyme systems were destroyed by heating at 100 degrees c. further purification was achieved b ... | 1978 | 104473 |

| a serologic survey of mule deer and elk in utah. | sera from mule deer (odocoileus hemionus) and elk (cervus canadensis) in central and northern utah were tested for the prevalence of antibodies to 11 diseases communicable to man or domestic livestock. antibodies to francisella tularensis (at 1:20) were found in 47 of 88 (53.4%) elk and 1 of 89 (1.1%) deer. a screening slide agglutination test for titers to brucella (at 1:20) showed two reactors in elk but none in deer sera. no positive antibody titers were obtained in tests for anaplasmosis, co ... | 1978 | 105153 |
| the preparation and immunosuppressive properties of equine antihuman thymocyte membrane immunoglobulin g. | human thymocytes separated by a ficoll gradient produced a cell population that was 99% pure thymocytes and free of platelets, leukocytes, and epithelial cells. these cells, disrupted by a nitrogen bomb, produced a membrane-ribosome antigen fraction confirmed by enzyme analysis. equine antithymocyte membrane-immunoglobulin g (atm-igc) prepared against this antigen in four of five horses contained immunosuppressive properties capable of prolonging monkey skin allograft survival longer than 21 day ... | 1979 | 105416 |
| [isolation of treponemas from the colon of pigs with clinical dysentery]. | optimal culture conditions in artificial nutritive media were determined for a defined avirulent strain of treponema hyodysenteriae and for four field strains of treponemas in pigs with clinical dysentery. the treponemas were isolated with the use of milliporous filters with pores of 0.3 micrometer in diameter, which were located on the surface of blood agar. no significant difference in the influence of equine, bovine or sheep blood on the growth of treponemas was determined. the commercial amo ... | 1979 | 105448 |

| [new species of microsporidians (microsporidia, nosematidae) from horsefly larvae in the ukraine]. | a new species of microsporidians, stempellia lairdi sp. n., was found in larvae of tabanus autumnalis l. from ukraine. it affects the muscular tissue and haemolymph of horse fly larvae. spores of the species are oval, egg-shaped, 1.8--7.6 x 1.2--3.8 mu in size. the species is pathogenic and causes the mortality of infected larvae. | 1979 | 108652 |
| preparative cell electrophoresis with d2o as a stabilizing agent. | the method of ascending preparative cell electrophoresis in a nonstabilized vertical column can be greatly improved by layering the cells on a starting cushion of buffer prepared in d2o and by stabilizing the liquid column above it with a d2o gradient. d2o/h2o mixtures have no apparent biochemical effects on the cells, and their physiochemical effects are short-lived and reversible. it was possible, by this method, to separate a mixture of glutaraldehyde-fixed erythrocytes of three species (rabb ... | 1979 | 108673 |
