Like viruses, many of them can only grow inside living cells, and they are frequently transmitted by mites, ticks, or lice. Genus Rickettsia, order Rickettsiales; Gram-negative rods Example sentencesExamples - It was interesting to note that neither the viruses nor the rickettsiae multiplied in this cell line.
- Biological weapons can come in a variety of forms, including viruses, bacteria, and rickettsia (bacteria that can live inside host cells like viruses).
- It usually takes several hours of attachment and feeding before the rickettsiae are transmitted to the host.
- These diseases result from a variety of infectious agents including bacteria, rickettsia, viruses and protozoa, or they may be caused by substances produced by the tick.
- Typhus is caused by rickettsia, bacteria-like microorganisms transmitted through blood-sucking insects such as fleas, lice, and ticks.
Derivatives adjective Comparative analyses of rickettsial genomes, therefore, provide an outstanding opportunity to study key features of degenerative processes as well as neutral sequence evolution. Example sentencesExamples - Maternally inherited rickettsial symbionts of the genus Wolbachia occur commonly in arthropods, often behaving as reproductive parasites by manipulating host reproduction to enhance the vertical transmission of infections.
- Other viral, bacterial, and rickettsial diseases (such as Rocky Mountain Spotted Fever) have also created a niche for themselves in response to behavioral and environmental changes.
- Post-infectious glomerulonephritis has also been associated with other bacterial, viral, parasitic, rickettsial and fungal infections.
