serologic, pathologic, and symptomatic aspects of mycoplasmosis of turkeys.adult male turkeys were exposed to mycoplasma gallisepticum isolate 1010 by either intratracheal inoculation, intrasinus inoculation, intranasal inoculation or by contact with inoculated turkeys. the symptomatic, serologic, and pathologic responses to the different types of exposure were compared. tracheitis occurred only in birds exposed intratracheally or by contact, and sinusitis occurred only in birds exposed via the sinuses. antibody titers, determined by hemagglutination-inhibition and tub ...196514300856

sialic acid binding sites: role in hemagglutination by mycoplasma gallisepticum.hemagglutination of turkey erythrocytes by mycoplasma gallisepticum was inhibited by mucoproteins containing sialic acid, by sialic acid itself, and by treatment of the erythrocytes with neuraminidase. neuraminidase treatment of the mucoprotein-rich inhibitors reduced or abolished their inhibitory activity. the findings indicate that sialic acid on the erythrocyte surface provides binding sites for mycoplasma gallisepticum.19665903587
the interaction of mycoplasmas with mammalian cells. i. hela cells, neutrophils, and eosinophils.the ultrastructure of three mycoplasma species, mycoplasma pneumoniae, mycoplasma gallisepticum, and mycoplasma neurolyticum, has been studied in isolated form as well as in hela cell cultures and following incubation with human peripheral blood leukocytes. during log growth phase, the organisms could be distinguished from each other on the basis of their fine structure. in mammalian cell cultures, pplo's appeared to proliferate on the plasma membranes which had markedly increased their surface ...19665922745
studies of pplo infection. iv. the neurotoxicity of intact mycoplasmas, and their production of toxin in vivo and in vitro.concentrated suspensions of washed mycoplasma neurolyticum produce rolling disease in mice and rats, with neurological manifestations and pathological lesions similar to those seen with the exotoxin of this organism. pretreatment of animals with tetracycline protects completely against the toxic effects of washed suspensions of mycoplasmas, while tetracycline affords no protection against the exotoxin. freeze-thawing disruption of mycoplasma suspensions eliminates their neurotoxicity, while the ...19665925315

studies of pplo infection. i. the production of cerebral polyarteritis by mycoplasma gallisepticum in turkeys; the neurotoxic property of the mycoplasma.turkey poults injected intravenously with suspensions of mycoplasma gallisepticum develop a fatal neurologic disease associated with polyarteritis affecting almost exclusively the cerebral arteries. the incubation period depends on the dose of organisms. with high doses (10(10) to 10(11) mycoplasmas) the birds become ill and die within a few hours; with lower doses (10(6) to 10(8)) neurologic manifestations appear after 7 days. the rapid onset of neurologic signs after high doses indicates the p ...19665938817

role of complement in immune inactivation of mycoplasma gallisepticum.studies were undertaken to evaluate the role of complement in the interaction between mycoplasmas and antiserum. a suspension of the a-1 strain of mycoplasma gallisepticum in pplo broth was incubated at 37 c with rabbit immune serum which had been heated for 30 min at 56 c. samples were removed from the mixture at timed intervals for 1 hr for titration of the mycoplasmas in broth. when normal guinea pig serum was included in the mixture at a final dilution of 1:40, the titer fell rapidly from 10 ...19674962702

histochemical localization of phosphatases in mycoplasma gallisepticum.histochemical studies of adenosine triphosphatase and acid phosphatase activity were performed on mycoplasma gallisepticum. the adenosine triphosphatase activity appears to be localized in the bleb and infrableb regions exclusively and is associated with the cell membrane; acid phosphatase activity is localized in the infrableb region and does not appear to be membrane-associated. these findings are consistent with data from biochemical studies of mycoplasma cell fractions but, unlike them, reve ...19674225891

sugar transport in mycoplasma gallisepticum.mycoplasma gallisepticum cells were found to contain two different sugar transport systems, one for d-glucose and alpha-methyl-d-glucoside (alpha-mg) and the other for d-mannose and d-fructose. both systems were noninducible, stereospecific, dependent on temperature and ph, and sensitive to sulfhydryl-blocking reagents. the rate of sugar uptake depended on its external concentration, obeying michaelis-menten kinetics. the sugar accumulated in the cells against a concentration gradient, and an en ...19695773029
