Entomophaga grylli is a fungal pathogen which infects and kills grasshoppers.It is the causal agent of one of the most widespread diseases affecting grasshoppers. This is sometimes known as summit disease because infected insects climb to the upper part of a plant and grip the tip of the stem as they die; this ensures widespread dispersal of the fungal spores.

Because of the impact of avian influenza on economically important chicken farms, a classification system was devised in 1981 which divided avian virus strains as either highly pathogenic (and therefore potentially requiring vigorous control measures) or low pathogenic. The test for this is based solely on the effect on chickens – a virus ...
[7] [8] The strategic planning involved a broadly deliberative process seeking input from employees, partners, and other stakeholders for selecting strategic objectives. [6] It emphasized preparedness as well as health promotion and disease prevention, and also streamlined the funding process for grants to state and local health departments.
Disease resistance is the host trait that prevents infection or reduces the number of pathogens and parasites within or on a host. Tolerance to infection can be illustrated via comparing host performance versus increasing load. This is a reaction norm in which host performance is regressed against increasing disease burden. [1]
Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus, which primarily affects birds but can sometimes affect mammals including humans. [1] Wild aquatic birds are the primary host of the influenza A virus, which is enzootic (continually present) in many bird populations.
The U.S. Centers for Disease Control and Prevention (CDC) state that "It is well documented that the most important measure for preventing the spread of pathogens is effective handwashing". [7] In the developed world, hand washing is mandatory in most health care settings and required by many different regulators. [citation needed]
The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels in a publication referred to as Biosafety in Microbiological and Biomedical Laboratories (BMBL).

The Centers for Disease Control and Prevention (CDC) estimated roughly 1.7 million hospital-associated infections, from all types of bacteria combined, cause or contribute to 99,000 deaths each year. [69] Other estimates indicate 10%, or 2 million, patients a year become infected, with the annual cost ranging from $4.5 billion to $11 billion. [70]
