|January 1, 1986
Abstract:
The group D staphylococcal phage P 1 was examined in the electron microscope after preparation by a variety of procedures. The virion was found to have an icosahedral capsid attached to a long contractile tail structure, the viral tail could be seen in partially contracted configurations. Morphological variants in the length of the sheath and needle were frequently found.
Insights
Group D staphylococcal phage P1 has an icosahedral capsid and a contractile tail structure. Electron microscopy revealed variations in tail sheath and needle length in this bacteriophage.
Area of Science:
- Microbiology
- Virology
- Electron Microscopy
Background:
- Bacteriophages are viruses that infect bacteria.
- Staphylococcal phages are important in understanding bacterial genetics and phage therapy.
- Group D staphylococcal phage P1 is a representative bacteriophage of this group.
Purpose of the Study:
- To characterize the morphology of group D staphylococcal phage P1 using electron microscopy.
- To investigate potential structural variations within the phage population.
Main Methods:
- Preparation of phage P1 samples using various procedures.
- Examination of phage morphology via electron microscopy.
Main Results:
- The phage P1 virion consists of an icosahedral capsid and a long contractile tail.
- Partially contracted tail structures were observed.
- Frequent morphological variations in tail sheath and needle length were noted.
Conclusions:
- Staphylococcal phage P1 exhibits a complex structure with a contractile tail.
- Morphological heterogeneity in tail components suggests potential functional or developmental variations.
