You don't specify the infection, so I will use Lyme Disease as an example. The nymph/baby tick goes for a small host. Prior to feeding, the nymph tick is not infected with anything. If the nymph deer tick feeds on a deer mouse, which are the carriers of Lyme disease, they become infected. If the nymph tick feeds on an animal, like a lizard, that isn't infected, the tick won't be infected. The progression is usually, deer mouse then larger host, such as deer, human, dog or other larger mammal.
Ticks get infected with the Lyme disease bacteria when they feed on an infected animal, such as mice or deer. The bacteria then multiply and are passed on to other hosts, including humans, through the tick's bite while feeding.
Usually, ticks go after blood.
Parasite. They live off of the blood of their host animals.
Animals like parasitic mites, ticks, and certain species of beetles and flies live on the surface of other animals. These animals rely on their host for food, shelter, and reproduction. They can be harmful to their host's health and survival.
Lyme disease is caused by a group of spirochete bacteria called Borrelia burgdorferi sensu lato. Ticks can get infected by these pathogens while sucking blood on an infected vertebrate. As ticks (well, not all ticks, but the ones that carry Lyme disease) feed at every stage of their lives on a different host, they can get infected at every stage.Some pathogens can circulate transovarially (i.e. an infected female tick's eggs are already infected), but that's not the case with Lyme disease.So basically a larva ('first stage tick') can't be infected until it has fed.Of course the chance of a tick getting infected while feeding on an infected host is not 100%.It's important to know, that if a tick once get infected with Lyme disease, it stays infected all it's life.Plus there's a small chance that a tick can get infected on an uninfected host by 'co-feeding'. That means that a tick basically sucks up the saliva (and also the spirochetes in it) of another tick that's eating nearby.So, the short answer to your question is: ticks can get Lyme disease at every stage.
Ticks survive on the blood of their host. No host and the tick will die a very slow death.
Ticks sucking blood from a host organism is an example of parasitism. The tick grows from its host, but contributes nothing to the host organism.
Seed ticks, which are the larval stage of certain ticks, are not contagious in the way infectious diseases are. They do not spread from one host to another through direct contact. Instead, they attach to a host, typically animals or humans, to feed on blood. While they can transmit diseases like Lyme disease or Rocky Mountain spotted fever, they require a host for transmission, not person-to-person contact.
According to the CDC's profile on Lyme disease, the bacteria that commonly causes the disease is known as Borrelia burgdorferi. Upon searching elsewhere for more specific information about the bacterium, I found an excerpt from an article published in 2012 in the journal Nature Reviews Microbiology. The full article is titled: Of ticks, mice, and men: understanding the dual-host lifestyle of Lyme disease spirochaetes and can be accessed through the archives of the journal's website. The article excerpt contained a diagram and explanation of a deer tick's life cycle. According to the article, deer ticks are infected with the bacteria after feeding on other infected animals such as birds, squirrels, and mice. Once infected, the tick will become a host for the bacterium for the remainder of its life. Interestingly enough though, the diagram indicates that infected female ticks do not transfer the bacteria into their eggs. Every new generation of ticks must acquire their own infection!
No. Ticks do not lay their eggs on exposed surfaces or on their host. They drop off a host to burrow into the ground to lay eggs.
Some examples of animals that live on the surface of other animals include certain species of mites, ticks, and parasitic insects. These organisms are known as ectoparasites because they live on the outside of their host's body, feeding off their blood or tissues. Examples include fleas, lice, and certain types of gnats.
No, they are a host for parasites such as ticks, mites, liver flukes, ect. Cattle are mammalian hooved animals that do not feed off of other animals, but only feed off of herbaceous plant matter.
