Lyme disease, also termed Lyme borreliosis, is caused by tick-transmitted spirochetes . diseases that can be transmitted directly or indirectly between animals and humans. These vectors may be parasites or other microbes. The best protection from mosquito-borne diseases is preventing the mosquito bites. Diseases: rodents carry a large number of diseases including bacteria, viruses, protozoa and helminths (worms). Housefly •Biological vectors –These vectors are involved in the life-cycle of parasite / arbovirus which must pass through the vector in order to mature to an effective stage capable of being transmitted to human or animal host when a vector takes a blood meal. Carrier is an individual which has the disease, but not symptoms; it is capable of transmitting the disease to a new individual. Previous authors: R A I NORVAL † AND I G HORAK.

The nematode Dirofilaria immitis causes serious disease of canines in the United States. and rash. Arthropods are important in causing diseases in their own right, but are even more important as vectors, or transmitters, of many different pathogens that in turn cause tremendous morbidity and mortality from the diseases they cause. Parma. According to WHO, mosquitoes form the major group of vectors responsible of different vector-borne diseases: they’re responsible of illnesses like Malaria, Dengue or Yellow Fever, as well as other diseases less famous like Lymphatic filariasis. (malarial parasite). The risk of tick-borne infection is reduced by avoiding tick bites and removing ticks from the body.
