Protein synthesis by intact Coxiella burnetii cells.
Coxiella burnetii was isolated from persistently infected fibroblast host cells by a rapid mechanical lysis technique. Macromolecular synthesis was initiated in these otherwise dormant cells by incubation at pH 4.5. The synthesis of protein proceeded for as long as 24 h. Initiation of protein synthesis in C. burnetii was dependent upon RNA synthesis. Approximately 24 species of polypeptides wer...
متن کاملCoxiella burnetii
Q fever has been described for the first time in 1935 as an outbreak of fever in workers of a slaughterhouse in Brisbane, Australia (Derrick, 1937). Derrick could not identify the aetiological agent therefore he defined the disease as “query fever”. Afterwards, in 1937, Burnet and Freeman (Burnet & Freeman, 1937) isolated a troublesome intracellular pathogen from mice inoculated with blood or f...
متن کاملCentrin scaffold in Chlamydomonas reinhardtii revealed by immunoelectron microscopy.
In the flagellate green alga Chlamydomonas reinhardtii the Ca(2+)-binding EF-hand protein centrin is encoded by a single-copy gene. Previous studies have localized the protein to four distinct structures in the flagellar apparatus: the nucleus-basal body connector, the distal connecting fiber, the flagellar transitional region, and the axoneme. To explain the disjunctive distribution of centrin...
متن کاملNuage Components and Their Contents in Mammalian Spermatogenic Cells, as Revealed by Immunoelectron Microscopy
The nuage is a germ cell-specific organelle that has been studied for more than a hundred years. It was first discovered in spermatogenic cells as a perinuclear granule stained by basic dyes and visualized using a light microscope. Morphological studies using electron microscopes demonstrated that ”chromatoid body (CB)” is a nuage component in spermatids, and that “inter-mitochondrial cement (I...
متن کاملSpecificity of Legionella pneumophila and Coxiella burnetii vacuoles and versatility of Legionella pneumophila revealed by coinfection.
Legionella pneumophila and Coxiella burnetii are phylogenetically related intracellular bacteria that cause aerosol-transmitted lung infections. In host cells both pathogens proliferate in vacuoles whose biogenesis displays some common features. To test the functional similarity of their respective intracellular niches, African green monkey kidney epithelial (Vero) cells, A/J mouse bone marrow-...
