full genome sequences of all nine chlamydia psittaci genotype reference strains.chlamydia psittaci primarily infects birds, but zoonotic transmission occurs in people in close contact with infected birds. the clinical outcome ranges from inapparent disease to pneumonia. here we report the genome sequences of all 9 chlamydia psittaci genotype reference strains.023209198
studies on the psittacosis-lymphogranuloma group. 1. the pattern of multiplication of meningopneumonitis virus in the allantois of the chick embryo.because of the peculiar properties of the psittacosis-lymphogranuloma group of viruses, the pattern of multiplication in the allantois of the chick embryo of one of their number, meningopneumonitis virus, was studied. this was done by determination of the changes in its infectivity for mice and chick embryos. titration of infectivity in embryos proved to be a more sensitive procedure than titration in mice; the latter procedure however, had the advantage of greater simplicity and gave more clear ...195114888822

studies on the psittacosis-lymphogranuloma group. ii. a non-infectious phase in virus development following adsorption to host tissue.the pattern of growth of meningopneumonitis virus in vitro seemed to be similar to that occurring in ovo and thus the initial stages of development, the adsorption and the latent periods, were investigated by the use of tissue culture procedures. the initial increment of infectivity in allantoic membrane suspensions following virus inoculation in ovo was due to prolonged adsorption of virus and not to immediate virus reproduction. the length of the adsorption period varied with the virus dilutio ...195214955577

intracellular forms of meningopneumonitis virus.electron micrographs of intracellular memngopneumonitis virus have shown several types of particles which are presumably representative of different stages of a life cycle. they are: (a) elementary bodies-dense particles 250 to 300 mmicro in diameter with very dense central granules. (b) intermediate forms-less dense than elementary bodies and larger. they are 300 to 400 mmicro in diameter, contain a very dense central granule, and often have two or three limiting zones, (c) circles 400 to 500 m ...195413211915

factors related to the growth of psittacosis virus (strain 6bc). iv. certain amino acids, vitamins, and other substances.the analogues of amino acids, beta-2-thienylalanine, ethionine, and 6-methyltryptophane, inhibited the growth of psittacosis virus (6bc) in tissue culture without evidence of serious toxicity for the host cells. of a number of vitamin analogues tested, only salicyl-beta-alanide inhibited viral multiplication in the absence of toxic effects on the host cells. 6,7-diethylriboflavin, desoxypyridoxine, and oxythiamine reduced viral growth in concentrations that possessed some toxicity for host tissu ...195413163321
studies on the factors essential to the initiation and maintenance of multiplication of psittacosis virus (6bc strain) in deficient cells in tissue culture.the growth of psittacosis virus (6bc) was studied in cultures of minced whole chick embryo tissue maintained in either hanks-simms solution or hanks's balanced salt solution (bss), and in neither medium could sustained, long-term virus growth take place. addition of beef embryo extract (bee) to cultures at a time when virus multiplication was declining reversed this general trend and resulted in greater virus growth. this virus-stimulating action of bee was only partially diminished by colchicin ...195413163322

latent viral infection of cells in tissue culture. ii. relationship of cell nutrition to initiation of growth of psittacosis virus.when chick embryo tissues cultivated for 13 days in hanks's balanced salt solution (bss) were infected with psittacosis virus (6bc), they did not support active viral multiplication until synthetic medium 199 of parker (3) was added. by testing various combinations of the substances in this and other synthetic media, it was found that the minimum number of compounds required to effectively stimulate virus growth in the presence of bss comprised the amino acids and water-soluble vitamins found in ...195613319591
