Possible definitions for infective

infection
Invasion of the body by various agents--incl. bacteria, fungi (see fungus), protozoans, viruses, and worms--and its reaction to them or their toxins. Infections are called subclinical until they perceptibly affect health, when they become infectious diseases. Infection can be local (e.g., an abscess), confined to one body system (e.g., pneumonia in the lungs), or generalized (e.g., septicemia). Infectious agents can enter the body by inhalation, ingestion, sexual transmission, passage to a fetus during pregnancy or birth, wound contamination, or animal or insect bites. The body responds with an attack on the invader by leukocytes, production of antibodies or antitoxins, and often a rise in temperature. The antibodies may result in short-term or lifelong immunity. Despite significant progress in preventing and treating infectious diseases, they remain a major cause of illness and death, particularly in regions of poor sanitation, poor nutrition, and crowding.


insectivore
Any member of the mammalian order (Insectivora) that includes the hedgehogs, moles, and sometimes shrews (some of which are considered primates by some authorities), or, more generally, any animal that eats mainly insects. The mammalian insectivores are generally small, active, and nocturnal. They are found in most parts of the world except Antarctica, Australia, and S. America. Most species are solitary (except during the breeding season) and short-lived.
