What does a high ID50 mean?
What does a high ID50 mean?
Inversely, high ID50 values are associated with motile and fast-growing bacteria that use quorum-sensing based regulation of virulence factors expression.
What is an ID50 value?
The ID50 value is defined as the concentration of antiviral drug required to reduce the HSV-specific DNA by 50% compared with the untreated virus controls.
How do microorganisms gain entry to the body?
Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier.
How do you know ID50?
The ID50 is estimated by interpolating the line that connects the hypothetical fractions of the bracketing doses [40]. Both methods rely on doses to be equally-spaced logarithmically, with each group containing equal numbers of subjects (e.g., pigs) for an accurate estimate of the dose–response.

What is ID50 and LD50?
The ID50 is the number of pathogen cells or virions required to cause active infection in 50% of inoculated animals. The LD50 is the number of pathogenic cells, virions, or amount of toxin required to kill 50% of infected animals.
What is LD50 and ID50?

Why do diseases re emerge?
Reemerging diseases are diseases that reappear after they have been on a significant decline. Reemergence may happen because of a breakdown in public health measures for diseases that were once under control. They can also happen when new strains of known disease-causing organisms appear.
