Biology of Bacterium Lepisepticum
1. Bacterium lepisepticum, Type D, inoculated in small amounts into meat extract broth, pH 7.4, under aerobic conditions failed to grow. Larger inoculations underwent a period of lag before the logarithmic growth phase began. 2. In this medium, dissociation of Microbe D to the variant G occurred readily. 3. A lowered oxygen tension in this broth resulted in growth of small numbers of Type D wit...
متن کاملBacterium Lepisepticum Infection
In this paper we have attempted to describe the manner of spread of an endemic, native, respiratory infection and a method for its control. The essential factor determining the prevalence of such an endemic disease is, we believe, host susceptibility, which is controlled by hereditary and environmental influences. Furthermore, it seems probable that the amount of this population susceptibility ...
متن کاملBiology of Bacterium Lepisepticum. Iii. Physical, Cultural, and Growth Characteristics of Diffuse and Mucoid Types and Their Variants. by Leslie T. Webster, M.d., and Caspar G. Burn
We have been engaged in the study of Baa. lepisepticum infection in rabbits with the purpose of finding out the mechanism which governs its natural prevalence. Thus far we have determined three factors which play essential parts: (1) host susceptibility; (2) microbic distributlon; and (3) microbic virulence. The first two of these have been discussed in previous papers (1); in this and the foll...
متن کاملThe Epidemiology of a Rabbit Respiratory Infection
Rabbits were bred at The Rockefeller Institute with special relation to protection from exposure to Bacterium lepisepticum. These healthy rabbits were then submitted to intranasal instillation of a given dose of cultures of Bacterium lepisepticum. The results of the inoculation were various according to the natural degree of resistance of the individual animals. The following graded effects cou...
متن کاملRole of Archaeal HerA Protein in the Biology of the Bacterium Thermus thermophilus
Intense gene flux between prokaryotes result in high percentage of archaeal genes in the genome of the thermophilic bacteria Thermus spp. Among these archaeal genes a homolog to the Sulfolobus spp. HerA protein appears in all of the Thermus spp. strains so far sequenced (HepA). The role of HepA in Thermus thermophilus HB27 has been analyzed using deletion mutants, and its structure resolved at ...
