2. In parasitology and entomology, a host organism that cannot be infected or sustains infection poorly compared to permissive hosts
Scientists identified the refractory host population and studied its genetic resistance mechanisms.
Os cientistas identificaram a população de hospedeiro refratário e estudaram seus mecanismos de resistência genética.
This is primarily a scientific and technical term used in parasitology, entomology, and epidemiology. It is commonly encountered in research contexts, particularly regarding disease vector control and transmission dynamics. The concept is crucial in understanding why certain populations or species are naturally resistant to specific diseases, which has important implications for public health strategies and vector control programs in both Brazil and international scientific communities.
