| transfer of parental immunity to infectious laryngotracheitis in chicks. | the transfer of parental immunity to infectious laryngotracheitis was appraised by measuring serum antibody levels in 150 chicks from the day of hatch up to five weeks. the breeder flock which had received primary vaccination at eight weeks and a booster at 20 weeks transferred high antibody levels which fell markedly within two weeks and remained constant thereafter. chicks whose parents were vaccinated at 20 weeks only, had low antibody levels throughout. these low levels, in either group of c ... | 1976 | 187298 |
| inhibition of herpesvirus saimiri replication by phosphonoacetic acid, benzo(a)pyrene, and methylcholanthrene. | the present investigations were undertaken to determine the possible effects of two carcinogenic polycyclic aromatic hydrocarbons, benzo(a)pyrene and 3-methylcholanthrene on herpesvirus saimiri replication. the results from these experiments were compared with the effects of phosphonoacetic acid on the virus replication cycle. phosphonoacetic acid inhibited the synthesis of virus-induced intracellular late antigens, membrane antigens and infectious virus but not the synthesis of the early antige ... | 1977 | 187336 |
| cell surface markers on epithelial-burkitt hybrid cells superinfected with epstein-barr virus. | attempts were made to superinfect two epithelial-burkitt hybrid cell lines, designated d98/hr-1 and d98/raji, with epstein-barr virus (ebv) and to investigate the expression of some cell surfacr markers including histocompatibility antigens, and the presence of b-cell markers, such as receptors for the third complement component and for monkey red blood cells. successful superinfection of d98/hr-1 cells with ebv was made evident by the expression of early antigen and, to a lesser extent, virus c ... | 1977 | 193641 |

| [arterio-veinous malformations located within the occipito-cerebello-mesencephalic dihedral (author's transl)]. | about 4 cases of arterio-veinous malformations located within the occipito-cerebello-mesencephalic dihedral (which is this region of the brain including the cistern of galen and the surrounding formations : the quadrigeminal bodies forwards, the splenium of the corpus callosum upwards, the upper face of the cerebellum and the pedonculus cerebellaris superior below) the authors related their own experience. these 4 cases are detailed from a clinical point of view. them, a synthetic study is under ... | 1978 | 313528 |

| reiter's syndrome following shigella flexneri 2a: a sequel to traveler's diarrhea. report of a case with hepatitis. | shigella flexneri 2a was isolated from a patient with reiter's syndrome (rs) following a family outbreak of traveler's diarrhea. among 3 members at risk, only the patient was positive for hla-b27. data from 3 similar families support the hypothesis that susceptibility to rs is genetically transmitted. it is urged that every effort be made to culture and subtype shigella and other enteric pathogens in rs following diarrhea. concurrently, the patient had hepatitis, interpreted as a parallel enteri ... | 1977 | 319805 |
| [formation of the dysentery epidemic process in three small towns]. | data are presented concerning the epidemiological analysis of sonnei dysentery outbreaks in three towns connected by common nutrition and water supply. the epidemic processes in these populated localites were strongly interrelated. possibilities of the effect of the water factor on the extent of sonnei dysentery incidence were studied as well. the results of studies led to the conclusion on the presence of numerous action forms of the water factor which should be taken into consideration in carr ... | 1977 | 320797 |
| [test of the safety, reactogeneity and immunogeneity of live flexner 2a and sonne dysentery vaccine from spontaneous mutants, prepared in dragee form, in a controlled experiment on adults]. | controlled experiment was conducted on 428 adult persons. a study was made of the reaktogenic properties and the immunological activity of live enteral dysentery vaccine flexner 2a and sonne from the spontaneous mutants developed at the n.f. gamaleya institute of epidemiology and microbiology. the vaccine is prepared in the form of sugar-coated pills covered with an acid-fast substance protecting from the gastric juice action. a single administration of the vaccine in a dose of up to 4 pills (6 ... | 1977 | 320801 |
| volume and shape of normal human spermatozoa. | an improved apparatus for measuring the electrical size of particles, developed in this laboratory and based on the principle of the coulter counter, is used to size human spermatozoa. the typical size distribution is unimodel, with a skew to the right. the actual quantity determined by the measuring system is electrical size (i.e., shape factor x volume); in order to extract the volume, it is necessary to obtain an independence measure of particle shape. this is done by estimating the relative ... | 1977 | 321264 |
| conservation of transfer ribonucleic acid and 5s ribonucleic acid cistrons in enterobacteriaceae. | the genes for tranfer ribonucleic acid (tdna) and 5s ribonucleic acid (5sdna) were isolated from the total deoxyribonucleic acid (dna) of escherichia coli. the relatedness of tdna and 5s from e. coli and other species of enterobacteriaceae was determined by reassociation of the isolated genes labeled with 32po4 to unlabeled, unfractionated dna. double-stranded dna was separated from unreacted dna by hydroxyapatite chromatography. thermal elution profiles were done to determine the amount of unpa ... | 1977 | 321428 |
| a simple one-step hemolytic assay for c2 with c2-deficient human serum. | a simple one-step procedure has been developed for the molecular titration of c2 by utilizing the ability of the test material to restore the hemolytic activity of human serum selectively deficient in c2 (c2d serum). in this assay, equal volumes of ea (10(8) cells/ml), c2d serum (1/20), and a suitable dilution of a source of c2 were incubated at 37 degrees c for 60 min and the fraction of cells lysed was used to calculate the effective molecules of c2/ml test material. the assay can be used to t ... | 1977 | 321681 |

| biological properties of shigella flexneri 2a toxin and its serological relationship to shigella dysenteriae 1 toxin. | a toxin extracted from heat-inactivated, alkaline-treated shigella flexneri 2a showed biological properties similar to those of shigella dysenteria 1 toxin. the s, flexneri 2a toxin was lethal to mice, enterotoxic for ileal loops of rabbits, and cytotoxic for hela cells. a serological relationship between s. flexneri 2a and s. dysenteriae 1 toxin was shown with cross neutralization tests. | 1977 | 323142 |
| the pathogenesis of shigella diarrhea. vi. toxin and antitoxin in shigella flexneri and shigella sonnei infections in humans. | two strains of shigella flexneri and one of shigella sonnei were studied for toxin production in vitro. all of the three strains produced a cell-free cytotoxin that showed marked similarity to that produced by shigella dysenteriae 1. each toxin eluted in two distinct peaks on chromatography with sephadex g-150, was destroyed by heating at 90 c for 30 min, and was neutralized by s. dysenteriae 1 antitoxin. patients with infections due to s. flexneri and s. sonnei developed antibody that neutraliz ... | 1977 | 323376 |
| clinical and laboratory assessment of the pathogenicity of serotyped enteropathogenic escherichia coli. | only one of 167 separate isolates of enteropathogenic escherichia coli (eec) was shown to produce enterotoxin, and none of the 167 isolates were invasive. clinical features of 123 hospitalized children with eec were compared with those of 917 infants with nonbacterial gastroenteritis and 145 infants infected with shigella. the average duration of diarrhea (five or more stools per day) in hospitalized children with eec, nonbacterial gastroenteritis, shigella flexneri, and shigella sonnei was 4.6, ... | 1977 | 323379 |
