They can infect the body and make you sick
Mostly flatworms are parasites that infect a variety of animals, including humans.
It seeks and eats other organisms.
Yes. There are roundworms of different species that can infect humans and they can cause serious health issues. Roundworms common in puppies and kittens are some of the roundworms that can infect humans which is why it is important to treat puppies and kittens for parasites early and as often as recommended by your veterinarian.
Their larvae is to a few species of bugs (since they work as parasites on them they get to)
No, they do not! The evidence shows that malaria parasites that infect lizards have two kinds of ribosomes and malaria parasites that infect lizards have only one.
Rabies infect humans depending on how far is the bite to your brain.
HIV does not infect plants. It affects humans.
No; leeches aren't vectors of dog true parasites but they can still infect them with other microorganisms like viruses.
Yes, it is possible to have parasites in the bloodstream. Certain parasites, such as Plasmodium (causative agent of malaria), trypanosomes (causative agent of sleeping sickness), and filarial worms can infect the blood and circulate within the bloodstream. These parasites can be transmitted to humans through the bite of infected insects or through contaminated blood transfusions.
Roundworms can also be parasites to humans.
I would say NO. Rabbits can of course get infested with lice, but normally not the type that infests us humans. If we humans have got headlice, then the headlice are not likely to infest the rabbit. Different species has got different parasites to cope with. There is only a few parasites that infect many different species. And even so, carnivore species (meat-eating) can all get certain parasites where as species not eating meat normally do not.
