Can you get body lice from the sand at the beach?
No, you can only get lice either from direct contact with a person that has them or by sharing personal items (e.g. combs, hairbrushes, cloths) with them.
Lice that fall off a person will rapidly starve to death and cannot be transferred.
What you are calling body lice are most likely the species of lice referred to as clothing lice, which actually live on the cloths but feed on the body underneath. The other two species are head lice and pubic lice.
Parasitescan cause infection of the nervous system can produce a variety of symptoms and signs. Because symptoms of infection are often mild proper or nonspecific, diagnosis can be difficult. Familiarity with basic epidemiological characteristics and distinguishing radiographic findings can increase the likelihood of trematodes detection and proper treatment of parasitic infection of the nervous system.
Why human infection is a dead end for the parasite?
Because it's very rare (unless you're a cannibal) to eat human meat we consider humans as the "dead end" host for the life cycle of the Trichina worm. There is no possible or ethical way of acquiring the worm through ingestion of human meat thus, the worm will just reproduce in your body over and over again until all your muscles are full of them...
In winter woodlice burrow down into rotting leaves or the earth, to protect themselves from the cold.
What is most likely to happen when a a parasite host dies?
One of 2 things:
- it dies with the host
- it must find a new host
One example are lancet flukes that parasitize ants, cattle, and snails. When the parasites are ready to move from the ant to cattle, every evening the parasites make the infected ant leave the anthill and climb to the top of a blade of grass; if grazing cattle in the night eat that blade of grass, the ant dies but the parasites have found their next host; if the ant has not been eaten by the morning and it remained on the blade of grass it would be baked in the sun and both the ant and the parasites would die before any cattle could eat them, so the parasites make the infected ant climb down and return to its normal life in the anthill. Once in cattle the parasites mature and lay eggs, which are excreted in manure, snails eat the manure and the eggs hatch in the snails, the newborn parasites are excreted in the snail's slime, which is eaten by ants.
How do you cure bloodsucker bites?

How are host and parasite related?
they are in the same body and the parasite lives on the host

What parasite causes Equine Protozal Myeloncephalitis?
Opossums are the definitive host for Sarcocystis neurona, which is the parasite that causes EPM (equine protozoal myeloencephalitis. The parasite is excreted from opossums in their manure which can then be ingested by the horse while grazing or drinking water.
Will rubbing alcohol kill plants?
Yes, if plants receive just a small amount you will see in just a week that your plant will start to dry up, the it will start to shrink in a few week's. This happens because the alcohol dries out the inside of the plant in a certain way that even if you give it water it will still die. Don't try using that on plants.

Yes.
Fleas get all of their sustenance from another life form- in this case, usually a furry life form. ( Fleas don't like horses or pigs. )They also rely on their unwilling host for transportation and contact with other hosts to further their long term reproductive designs.
yes sort of
Are parasites a type of algae?
No. A parasite is an animal or plant that lives in or on another animal or plant and gets food or protection from it. For example- mistletoe is a plant that grows in a tree, and sucks nutrients from the tree.
Why do parasites in harm but not kill their host?
By definition a parasite is harmful. Any number of diseases that you can think of caused by bacteria, viruses, worms, lice or amoebae are parasites. Their job is not to live with you but to use you as a source of food and to make more parasites like themselves. Some parasites do live a long time on you or in you but they always cause harm.
What are opportunistic parasites?
Dogs are a good example of an opportunistic predator: they take immediate advantage of any situation that benefits them, ( begging for or stealing food). As a predator: they prey, attack and capture however being opportunistic they also scavenge because it's easier than hunting.
Is a parasite an animal or a plant?
A parasite has one main function - to derive its most basic needs (food, shelter, safety) off of a host. The host may or may not permit the parasite to stay, depending on the circumstances. They only take, they do not give anything to the host except for potential pain and/or suffering in some form.
What type of people study parasites?
People who study parasites are typically scientists or researchers with backgrounds in fields such as parasitology, biology, veterinary medicine, or public health. They are interested in understanding the biology, ecology, and impact of parasites on their hosts and ecosystems.
Kids usually get lice from direct head-to-head contact with someone who already has lice. Lice can crawl from one person's hair to another's, especially in school, during sleepovers, or when playing closely together. Sharing hats, brushes, or hair accessories can also spread lice.
Is it beneficial for the parasite to kill its host?
It is rare, but yes sometimes.
A few parasites don't directly kill their host, but make them do "careless things" that make it more likely the host will get eaten by the parasite's next host.
Can roundworms be passed human to human?
Round worms do not transfer from human to human directly. The female round worm passes thousands of ova in the stool of host, after fertilization. The ova get conditioned in the soil. When these ova are ingested by another person, he gets the infestation by round worm.
What are the common symptoms of Trichinosis?
With a mild case you my have no symptoms. With a more extensive infestation after a day or so
you may have Diarrhea and Abdominal pain. This is the first phase. Phase two begins after about a week and may involve high fever, muscle pain and tenderness and swelling of the eyelids or face.
If you're worried you have trichinosis, it's veryunlikely. Only 20 cases are reported in the U.S. each year. This means there's only one chance in 15 million you have these worms.
What parasites are in a leopard?
Leopards can be hosts to various parasites such as ticks, fleas, mites, and internal parasites like roundworms and tapeworms. These parasites can have negative impacts on the health and behavior of leopards if left untreated. Regular monitoring and control measures are important for maintaining the health of leopard populations.
How is undigested material eliminated in Clonorchis sinensis?
Undigested materials are removed through their mouth because they do not have an anus.
What parasites are found in the alimentary canal of a man?
Common parasites found in the alimentary canal of humans include roundworms, tapeworms, hookworms, and giardia. These parasites can cause a range of symptoms such as abdominal pain, diarrhea, and weight loss. Proper diagnosis and treatment by a healthcare professional are necessary to eradicate these parasites.
