1. Viruses are non-living infectious agents that can only replicate inside host cells. They contain genetic material in the form of DNA or RNA surrounded by a protein coat.
2. Early experiments in the late 19th century demonstrated that certain disease-causing agents could be transmitted between hosts and passed through filters, establishing the existence of viruses.
3. Viruses come in a variety of shapes and sizes but are generally quite small, usually between 20-300 nanometers. Their structure includes a nucleic acid core and protein coat called a capsid, which is composed of repeating protein subunits called capsomeres.

Influenza virus notes
Influenza A viruses can be broken down into sub-types depending on the genes that make up the surface proteins. Over the course of a flu season, different types (A & B) and subtypes (influenza A) of influenza circulate and cause illness.
More Information about Flu Viruses
Types of Influenza Viruses
Influenza A and B viruses are responsible for seasonal flu epidemics each year.
How the Flu Virus Can Change
Influenza viruses can change in two different ways—antigenic drift and antigenic shift.
Transmission of Influenza Viruses from Animals to People
Influenza A viruses also are found in many different animals, including ducks, chickens, pigs, whales, horses and seals.
Antigenic Characterization of Influenza Viruses
“Antigens” are molecular structures on the surface of viruses that are recognized by the immune system and are capable of triggering an immune response (antibody production).
2009 H1N1 Influenza
The influenza A (H1N1) virus that emerged in 2009 caused the first global influenza pandemic in more than 40 years.

Transmission of plant viruses
Plant viruses are transmitted from plant to plant in a number of ways.
Transmission of viruses by vegetative propagation.
Mechanical transmission of viruses through sap.
Transmission of viruses by seed.
Transmission of viruses by Pollen.
Transmission of viruses by dodder.
Transmission by vectors.
Transmission of plant virus
Transmission of plant viruses can occur horizontally by vectors like insects, contaminated tools, or vertically through propagation materials like seeds or cuttings. There are two main types of transmission: non-persistent and persistent/circulative. Non-persistent viruses are acquired quickly but not retained long in vectors, while persistent viruses have longer acquisition times and retention periods in vectors. Aphids are the most important insect vectors, and can transmit viruses in non-persistent, semi-persistent, or persistent/circulative manners depending on how long they retain the virus. Mechanical transmission under laboratory conditions is also discussed.
Viruses in reptiles
There are many viruses that infect reptiles from different virus families such as Herpesviridae, Paramyxoviridae, Poxviridae, Adenoviridae, Papillomaviridae, Reoviridae, and Arboviruses. Many of these viruses cause respiratory, skin, or neurological symptoms in reptiles. However, little is known about the transmission and diseases caused by reptilian viruses due to the low commercial value of reptiles and difficulties in research.

Virus Transmission
This document discusses virus transmission and the various modes by which viruses can spread from person to person or host to host. It explains that transmission depends on viral concentration and route, with higher concentration leading to higher transmission chances. Some key transmission routes mentioned are respiratory secretions, blood, saliva, feces, and various entry points into the host like skin, eyes, and respiratory or alimentary tracts. The document also outlines some inherent barriers hosts have against viral infection, such as skin, lack of receptors, mucus, ciliated epithelium, and low pH levels.
Introduction mycology
This document provides an introduction to mycology, the study of fungi. It discusses the history of fungi being recognized as pathogens and outlines the key characteristics of fungi such as cell walls containing chitin. Fungi can be classified based on cell morphology into yeasts, molds, and dimorphic fungi. They can also be classified based on sexual reproduction into four classes. Common fungal infections like dermatophytosis and opportunistic infections are described. The document concludes by noting some useful properties of fungi such as food production and antibiotic production.

Bats
The document discusses white-nose syndrome, a fungal disease that has led to the extinction of many bat species. It is caused by a white fungus, Geomyces destructans, that grows on bats' skin during hibernation and causes them to use up their fat reserves and die before spring. The disease kills bats by depleting their energy, compromising their immune systems, damaging their wings, and altering their behavior. Its impact is significant because bats control insect populations and help ecosystems and agriculture.
Virus vector relationship
This document discusses terminology related to virus transmission by vectors and different types of virus-vector relationships.
1. It defines terms like acquisition access period, acquisition feeding period, inoculation access period, inoculation feeding period, and transmission threshold that describe the process of a vector acquiring and transmitting a virus.
2. It describes three main types of virus-vector relationships: non-persistent, semi-persistent, and persistent. Non-persistent viruses are stylet-borne and lost quickly. Semi-persistent viruses persist for 10-100 hours in the foregut. Persistent viruses circulate and may multiply in the vector.
3. Within persistent viruses, it further distinguishes circulative non-propagative
structure morphology_of_viruses
Viruses have a basic structure consisting of nucleic acid surrounded by a protein coat called a capsid. Some viruses have an additional phospholipid envelope. Viruses come in a few different symmetries for their capsids including icosahedral, helical, binal, and complex. Icosahedral capsids can be enveloped or non-enveloped while helical capsids are long and spiral-shaped. Binal symmetry combines icosahedral and helical features with a head and tail. Complex symmetry refers to asymmetrical virus structures.

This presentation provides an overview of viruses including:
1) It defines viruses as ultra-microscopic agents consisting of nucleic acid and protein that can only replicate inside host cells.
2) It discusses the history of virus discovery and key figures like Ivanovsky, Beijerinck, and Stanley.
3) It describes the typical characteristics of viruses like their acellular and obligate parasitic nature, composition of nucleic acid and protein capsids, small size, and inability to metabolize.
4) It covers virus morphology, classification based on shape, size, nucleic acid, and host range, and the multi-step process of viral replication within host cells.
5) It discusses common
Viruses bacteria protists_and_fungi
The document discusses classification systems for viruses, bacteria, protists, and fungi. It describes the current three domain system which classifies organisms into Archaea, Bacteria, and Eukarya domains based on rRNA structure. Viruses are described as non-living particles that invade and multiply within host cells. They have a protein coat, genetic material, and surface proteins. Bacteria are classified according to characteristics like shape, staining, metabolism. Gram staining distinguishes between Gram positive and Gram negative bacteria based on cell wall thickness.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
