Viruses and bacteria are microscopic organisms that can cause infection. Viruses are non-living particles that enter and reproduce inside living cells. They come in various shapes and sizes smaller than cells, and have a protein coat and genetic material. Bacteria are single-celled organisms that lack a nucleus and other structures found in more complex cells. They also appear in different shapes and sizes around 0.5-1 micrometer. Both viruses and bacteria can infect and potentially harm their host cells.

HSV-1 and HSV-2 are ubiquitous viruses that cause infections through direct contact with infected secretions. They establish latency in sensory ganglia after primary infection and can reactivate, causing lesions. Clinical presentations depend on the virus type and location of infection. Common manifestations include orolabial lesions from HSV-1 and genital lesions from HSV-2, as well as infections at other sites in immunosuppressed individuals or through direct contact during activities like wrestling.Lect 16 Viruses and Bacteria

Viruses are infectious agents that do not have cells and require a host cell to multiply. They contain either DNA or RNA and come in a wide range of sizes. Viruses infect hosts by taking over the host cell's functions to produce more viruses, either through a lytic or lysogenic cycle. Some viruses can cause diseases by disrupting cell functions or initiating cancer. Bacteria are prokaryotic cells that can be harmful or helpful pathogens. They reproduce through binary fission and cause diseases by attaching to and damaging cells. Examples of bacterial infections include syphilis and gonorrhea.Cytopathic Effects Of Viral Infections

Tissue and cell culture techniques allow viruses to be isolated and grown in vitro. Viruses are cultured by inoculating clinical specimens into various cell lines and monitoring for cytopathic effects that indicate viral infection. Identification of viral isolates is based on the type of cytopathic effects observed and can be confirmed through immunoassays or plaque assays, which involve counting viral plaques to determine viral titers. Proper transport and processing of clinical samples as well as optimized cell culture conditions are important for successful viral isolation.Virology 2014

Virology is the study of viruses and their relationship with hosts. Viruses are acellular organisms that can only replicate inside host cells. They have nucleic acid genomes and use host cell machinery to assemble new viral particles. Viruses come in a variety of shapes and sizes, and some have envelopes derived from host cell membranes. They enter host cells, express their genes, replicate their genomes, assemble new viral particles, and exit host cells to infect new targets. Viruses are cultivated using various methods including cell cultures, embryonated eggs, and animal models to study viral replication and pathogenesis.

Viruses can be cultivated within suitable host cells like bacteria to allow for viral replication. Bacteriophages are commonly grown by adding them to a culture of bacteria in a growth medium. The bacteriophages will multiply within the bacteria, destroying cells and releasing new viral particles. Viruses are also cultivated in tissue culture systems using cell lines grown in suspension. The virus infects the host cells, forcing them to produce new virus copies until the cells are lysed. Viral titers can be determined using plaque assays, where viral plaques are counted, or animal inoculation studies.Lab diagnosis of viruses

Viruses exist at the boundary between living and non-living things. They consist of nucleic acids and proteins but cannot reproduce outside of a host cell. Viruses come in different shapes and sizes and have unique structures suited to their method of infection. They hijack the machinery of living cells to reproduce either through lytic or lysogenic cycles, ultimately resulting in the destruction of the host cell. While viruses rely on host cells, they are not considered alive as they do not have their own metabolism or respond to their environment.Chapter 2 classification of virus

The document discusses two volcanoes - Mount St. Helena in California and Mount St. Helens in Washington. It explains that 3 million years ago, an eruption from Mount St. Helena covered the area in ash and buried massive redwood trees, which later became petrified and now make up the world's largest petrified forest. It also describes the 1980 eruption of Mount St. Helens, how it blew down surrounding trees and the extensive damage caused. The document provides details on how wood becomes petrified through replacement with silica minerals and how the eruptions of these two volcanoes led to the formation of famous petrified sites.Facilitation Techniques

How could modern LA research address data-related ethics issues in informal and situated professional learning? I will identify in this talk three relevant insights based on field studies around workplace LA interventions: Firstly, in informal and situated learning, data isn’t just about the learners. Secondly, the affordances of manual and automatic data tracking for learning are very different, with manual tracking allowing a high degree of learner control over data. Thirdly, learning is not necessarily a shared goal in workplaces. These can be translated into seeing a potential for systems endowed with sufficient natural-language-processing capability (now seemingly at our fingertips with LLMs), and socio-technical design and scenario-based data collection analysis as design and research methods.Direct Gene Transfer Techniques for Developing Transgenic Plants

Iron oxide-hydroxide minerals in Martian dust provide crucial insights into
Mars’ past climate and habitability. Previous studies attributed Mars’ red color
to anhydrous hematite formed through recent weathering. Here, we show that
poorly crystalline ferrihydrite (Fe5O8H · nH2O) is the dominant iron oxidebearing phase in Martian dust, based on combined analyses of orbital, in-situ,
and laboratory visible near-infrared spectra. Spectroscopic analyses indicate
that a hyperfine mixture of ferrihydrite, basalt and sulfate best matches Martian dust observations. Through laboratory experiments and kinetic calculations, we demonstrate that ferrihydrite remains stable under present-day
Martian conditions, preserving its poorly crystalline structure. The persistence
of ferrihydrite suggests it formed during a cold, wet period on early Mars
under oxidative conditions, followed by a transition to the current hyper-arid
environment. This finding challenges previous models of continuous dry oxidation and indicates that ancient Mars experienced aqueous alteration before
transitioning to its current desert state.(Journal Club) - RNA m6A regulates transcription via DNA demethylation and ch...

Viruses and Bacteria
- 2. Viruses • A tiny, non-living particle that enters and then reproduces inside a living cell • Needs a host, which provides a source of energy • Parasite – Lives on or in a host and can cause harm
- 3. Shapes • Round, rod-shaped, bricks, threads, bullets, robot-like shapes
- 5. Sizes • Smaller than cells • Cannot be seen with school microscopes • Measured in nanometers – 1 billionth of a meter
- 6. Structure • Two basic parts – Protein coat which protects itself – Inner core • Genetic material
- 7. Surface Proteins • Can attach to host cells • Lock and key • Specific
- 8. Multiply • Inside host cell – Virus’s genetic material takes over many cell functions – Instructs cell to produce the virus proteins and genetic material – Make new virus’s
- 9. Bacteria • Anton van Leeuwenhoek (late 1600s) – Scrapings from teeth – Could only see shapes, but not the parts inside the cells
- 10. Bacteria • Prokaryotes – Genetic material is not contained in a nucleus (have no nucleus) – Lack some other structures as well
- 11. Shapes and Sizes • Spherical, rodlike, spiral • Vary in size, average is about 0.5-1 micrometer – 1 millionth of a meter
