Host-parasite relationship in paracoccidioidomycosis.

Paracoccidioidomycosis (Pbmycosis) is a systemic disease confined to Latin America; its endemic areas extends from Mexico through Central and South America down to Argentina. Paracoccidioides brasiliensis (Pb), its agent, causes disease and mortality specially in rural populations being a major public health problem1). The disease was first reconized by Adolfo Lutz in 1908, in Sao Paulo. Its ag...

Recognition and polymorphism in host-parasite genetics.

Genetic specificity occurs in many host-parasite systems. Each host can recognize and resist only a subset of parasites; each parasite can grow only on particular hosts. Biochemical recognition systems determine which matching host and parasite genotypes result in resistance or disease. Recognition systems are often associated with widespread genetic polymorphism in the host and parasite popula...

Parasite and host elemental content and parasite effects on host nutrient excretion and metabolic rate

Ecological stoichiometry uses the mass balance of elements to predict energy and elemental fluxes across different levels of ecological organization. A specific prediction of ecological stoichiometry is the growth rate hypothesis (GRH), which states that organisms with faster growth or reproductive rates will require higher phosphorus content for nucleic acid and protein synthesis. Although par...
