Infectious agents run the gamut from virus and bacteria to fungi, protozoans, and helminths (worms). There is generally a preferred cell or tissue of invasion (called a tropism), and therefore each agent tends to have a defined spectrum of potential injury. Viruses multiply intracellularly, app...
(months or years). If the pathogen is not cleared by the immune response, the infection is described aspersistent. If an infectious agent persists without replicating, the infection is calledlatent. A latent infection canreactivate; the agent can replicate and cause illness if theimmune system...
Infectious keratitis, commonly called corneal ulceration, is one of the leading global causes of unilateral blindness; it has been described as a ‘silent epidemic’ [100]. The visual burden of infectious keratitis in resource-poor settings greatly exceeds that in rich countries, prompting a propo...
