Rhipicephalus sanguineus (Latreille, 1806) |

Overview
The brown dog tick, Rhipicephalus sanguineus, is a species of tick which is found worldwide, but more commonly in warmer climates. This species is unusual among ticks in that its entire life cycle can be completed indoors.[1]
Life Cycle
General Tick Life Cycle
![](/images/2/24/Lifecycle.jpg)
- A tick's life cycle is composed of four stages: hatching (egg), nymph (six legged), nymph (eight legged), and an adult.
- Ticks require blood meal to survive through their life cycle.
- Hosts for tick blood meals include mammals, birds, reptiles, and amphibians. Ticks will most likely transfer between different hosts during the different stages of their life cycle.
- Humans are most often targeted during the nymph and adult stages of the life cycle.
- Life cycle is also dependent on seasonal variation.
- Ticks will go from eggs to larva during the summer months, infecting bird or rodent host during the larval stage.
- Larva will infect the host from the summer until the following spring, at which point they will progress into the nymph stage.
- During the nymph stage, a tick will most likely seek a mammal host (including humans).
- A nymph will remain with the selected host until the following fall at which point it will progress into an adult.
- As an adult, a tick will feed on a mammalian host. However unlike previous stages, ticks will prefer larger mammals over rodents.
- The average tick life cycle requires three years for completion.
- Different species will undergo certain variations within their individual life cycles. [2]
Spread of Tick-borne Disease
- Ticks require blood meals in order to progress through their life cycles.
- The average tick requires 10 minutes to 2 hours when preparing a blood meal.
- Once feeding, releases anesthetic properties into its host, via its saliva.
- A feeding tube enters the host followed by an adhesive-like substance, attaching the tick to the host during the blood meal.
- A tick will feed for several days, feeding on the host blood and ingesting the host's pathogens.
- Once feeding is completed, the tick will seek a new host and transfer any pathogens during the next feeding process. [2]
Hosts
Rhipicephalus sanguineus will feed on a wide variety of mammals, but dogs are the preferred host in the U.S., and the population can reach pest proportions in houses and kennels.[1]
Rhipicephalus sanguineus Transmitted Diseases
- R. sanguineus is one of the most important vectors of diseases in dogs worldwide.[3]
- In the United States, R. sanguineus is a vector of the diseases in dogs: canine ehrlichiosis (Ehrlichia canis) and canine babesiosis (Babesia canis).
- R. sanguineus has not been shown to transmit the bacteria which causes Lyme disease in humans.[1]
- In parts of Europe, Asia and Africa, it is a vector of Rickettsia conorii, known locally as Mediterranean spotted fever, boutenneuse fever, or tick typhus.[1]
- R. sanguineus can also transmit Rocky Mountain spotted fever in humans in the southwestern United States.[4]
Management
The best management strategy is prevention of infestations in the house or kennel. In addition, the earlier the infestation is discovered, the easier it is to control. Regular grooming and inspection of pets is essential to management, especially when dogs have been quartered or have interacted with other dogs.[1]
