[arthropodan vectors of human parasites: their pathology and defence reactions (author's transl)].	many infectious diseases of man are transmitted by arthropods. it is not known whether the carriers were primarily susceptible or insusceptible as the cycle first came into existence. similarly so little is understood, why some arthropods are suitable vectors and other close relatives are not suitable. only the hypothesis that the agents are original parasites and not at all commensals or symbionts can reasonably explain the evolution of the cycles. it is shown by means of numerous examples how ...	1976	769379
[several biological properties of the surface antigens of the agent of pseudotuberculosis].	capsular substance and extracellular proteins of the causative agent of pseudotuberculosis caused in the organism of guinea pigs a specific immunological reconstruction with the accumulation in the blood of antibodies in low titres, chiefly of macroglobulin type. the blood sera of these animals failed to protect the mice from lethal pseudotuberculosis infection in experiments of passive protection. surface antigens of pseudotuberculosis causative agents produced a sensitizing action on the guine ...	1975	769431
less frequently reported gram-negative fermentative rods.	the clinical significance and distinguishing characteristics of less frequently reported gram-negative fermentative rods (pasteurella, yersinia, vibrio, aeromonas and plesiomonas, enterobacter agglomerans, and chromobacterium) are described. increased awareness of these organisms, a knowledge of possible sites in which they cause infection, and identification criteria which will separate them from similar bacteria will prepare the clinical microbiologist for the isolation and identification of t ...	1976	769548
immunologic phenomena in experimental rodentiosis. i. development of delayed skin reactions and peritoneal macrophage migration inhibition in guinea pigs infected with yersinia pseudotuberculosis.	hypersensitivity in guinea pigs infected with yersinia pseudotuberculosis was studied by means of skin tests and the migration inhibition test using peritoneal macrophages. delayed hypersensitivity developed in the course of rodentiosis. intensity of delayed skin reactions and degree of migration inhibition of peritoneal macrophages in the presence of specific antigen were strictly correlated.	1976	769739
immunologic phenomena in experimental rodentiosis. ii. cellular and humoral factors in immunity to infection with yersinia pseudotuberculosis.	humoral and cellular mechanisms of immunity to infection with y. pseudotuberculosis bacilli in mice were studied. development of delayed hypersensitivity, measured by the footpad test and macrophage migration inhibition test, was significantly correlated with immunity, expressed by elimination of y. pseudotuberculosis cells from the organs of infected mice. passive transfer of hypersensitivity and immunity was possible only by using peritoneal cells, while specific serum was inactive in this res ...	1976	769740
