The Morphology of Bacterium tularense.
Divergent views exist concerning the morphology of Bacterium tularense. McCoy and Chapin's (1912) original description depicted an apparently immotile, small, questionably encapsulated, pleomorphic organism occasionally presenting enlarged, irregular, and apparent involution fonns; sometimes with predominant large globular forms. Ohara, Kobayashi, and Kudo (1935) claimed to have demonstrated fl...
متن کاملSome Observations on the Filtrability of Bacterium tularense.
Throughout our morphologic study of Bacterium tularense in liquid medium cultures we noted constantly the presence of very minute forms (Hesselbrock and Foshay, 1945). These appeared to grade downward in size from the most prevalent coccoid or ring forms of about 0.5 ,u in diameter to bodies so small that neither size nor shape was discernible. Such particles were never seen in uninoculated med...
متن کاملCultivation of Bacterium tularense in Simplified Liquid Media.
Since the isolation and cultivation of Bacterium tularense by McCoy and Chapin in 1912, and the demonstration of its obligate cystine requirement by Francis in 1922, little has been written concerning its nutritional requirements. Lufkin and Evenson (1936-7) reported "abundant growth" of Bacterium tularense in a "routine" blood culture in glucose beef infusion broth. It is clear that the organi...

متن کاملObservations on the Infection of Chick Embryos with Bacterium Tularense, Brucella, and Pasteurella Pestis
1. Comparison of the infections of chick embryos by the chorio-allantoic route indicates that Bacterium tularense and Brucella suis, abortus, and melitensis exhibit varying degrees of facultative intracellular parasitism. Pasteurella pestis is adapted to rapid proliferation and spread in the intercellular fluids. 2. In the early stages of infection Bacterium tularense has a marked affinity for ...
