TRANSMITS Rickettsia rickettsii (Rocky Mountain spotted fever), Colorado tick fever virus (Colorado tick fever), and Francisella tularensis (tularemia). COMMENTS Adult ticks feed primarily on large mammals. Larvae and nymphs feed on small rodents. Adult ticks are primarily associated with pathogen transmission to humans.
Aphaniptera. Flea, the common name for the order Siphonaptera, includes 2,500 species of small flightless insects that live as external parasites of mammals and birds. Fleas live by ingesting the blood of their hosts. Adult fleas grow to about 3 millimetres ( inch) long, are usually brown, and have bodies that are "flattened" sideways or narrow ...
Rocky Mountain spotted fever ( RMSF) is a bacterial disease spread by ticks. [9] It typically begins with a fever and headache, which is followed a few days later with the development of a rash. [3] The rash is generally made up of small spots of bleeding and starts on the wrists and ankles. [10]
Information. Ticks are well-recognised bloodsucking external parasites of humans, pets, livestock, and wild animals. They also are vectors of a wide variety of disease-causing organisms to animals including humans. Ticks are wingless and possess a single, oval body region that is relatively flat (except when engorged with the host’s blood).
The dog ( Canis familiaris [4] [5] or Canis lupus familiaris [5]) is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from extinct gray wolves, [6] [7] and the gray wolf is the dog's closest living relative. [8] The dog was the first species to be domesticated [9] [8] by humans.
Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. [1] They are caused by infection with a variety of pathogens, including rickettsia and other types of bacteria, viruses, and protozoa. [2] The economic impact of tick-borne diseases is considered to be substantial in humans ...
