Parasitology

Urea is synthesised in the liver, from the oxidation of amino acids and/or ammonia. Look up "urea cycle" for details about this process. It is then transported (in the blood) to the kidneys and excreted to the bladder, and exits the body with the urine.

Raw or undercooked meats, seafood, and fresh produce have been associated with parasites such as tapeworms, roundworms, and protozoa. It is important to properly cook and handle these foods to minimize the risk of parasitic infections.

Parasite is an organism, that lives off another organism.

Pathogen is something that causes disease in another organism.

So the answer is "Yes".

eg Malaria is a disease caused by a parasite.

Endoparasites can exist in one of two forms: intercellular (inhabiting spaces in the host's body) or intracellular (inhabiting cells in the host's body). Intracellular parasites, such as bacteria or viruses, tend to rely on a third organism which is generally known as the carrier or vector. The vector does the job of transmitting them to the host. An example of this interaction is the transmission of malaria, caused by a protozoan of the genus Plasmodium, to humans by the bite of an anopheline mosquito.

Vesicles are small sacs or blisters that parasites can form to help them move, feed, or reproduce. They can contain various materials such as digestive enzymes or waste products, and play a role in the parasite's lifecycle and interactions with its host.

Scabies is a skin infestation caused by the itch mite Sarcoptes scabiei. The mite burrows into the skin, laying eggs that lead to intense itching and a rash. It is highly contagious and can be spread through close physical contact.

The vector responsible for transmitting many diseases caused by bacteria, viruses, rickettsiae, and protozoa is the mosquito. Mosquito-borne diseases include malaria, dengue fever, Zika virus, and West Nile virus, among others.

No, mosses are not parasites. Mosses are non-vascular plants that obtain nutrients through photosynthesis and do not rely on other organisms for their nutrition. They usually grow on rocks, soil, or tree bark.

Some common parasitic members of the phyla that infect humans include Platyhelminthes (flatworms) like tapeworms and flukes, Nematoda (roundworms) such as hookworms and pinworms, and Arthropoda (arthropods) like mosquitoes and ticks which transmit diseases.

Ear pain is not a common symptom of having lice. Typically, the primary symptoms of a lice infestation include itching on the scalp, neck, and ears. If you are experiencing ear pain, it is recommended to consult a healthcare provider for proper evaluation and treatment.

The most common parasite found in urine is Trichomonas vaginalis, a protozoan parasite that causes trichomoniasis, a sexually transmitted infection. It is typically detected in urine samples from individuals with genitourinary symptoms.

yes you can if the lice lay eggs on an article of clothing and you put it on

Yes, it is possible to contract sexually transmitted infections (STIs) from unprotected sexual contact with an infected partner. Parasitic STIs such as trichomoniasis and pubic lice can be transmitted through sexual activity. Practicing safe sex and getting tested regularly can help prevent the transmission of parasites through sexual contact.

The size of the Plasmodium parasite varies by species. For example, Plasmodium falciparum, the most deadly species causing malaria in humans, is about 1-2 micrometers in diameter and 7-15 micrometers in length in its mature stage.

Plant lice, also known as aphids, can vary in appearance based on species. They are small, soft-bodied insects typically measuring 1-4 millimeters long with a pear-shaped body. They come in various colors including green, yellow, brown, or black. If you search online for "aphid images," you'll find a wide range of photos showing different species of plant lice.

Bone is not a biological hazard, as it is a part of the human body and is not considered harmful unless it is infected or damaged. Fungi, bacteria, and parasites are all biological hazards that can cause health issues.

Medications such as permethrin, malathion, and ivermectin are commonly used to treat mites and lice infestations. They work by attacking the nervous system of the parasites, effectively killing them. It's important to follow the instructions of healthcare professionals when using these medications.

Cowbirds are considered parasites because they lay their eggs in the nests of other bird species. The host bird then raises the cowbird chick as if it were its own, often at the expense of its own offspring. This behavior can harm the reproductive success of the host bird species.

Cowbirds are considered parasites because they lay their eggs in the nests of other bird species, relying on them to raise their young. This behavior allows cowbirds to save energy and resources that would otherwise be spent on nest-building and caring for their own offspring. However, this can negatively impact the host bird species by increasing competition for resources and reducing the survival of their own chicks.

Yes, lice have exoskeletons. An exoskeleton is a hard outer covering that provides support and protection for the body of the louse.

Scabies mites are parasites that cause tiny raised red bumps or scabs that are often in a row on the skin. These mites burrow into the skin to lay eggs, leading to intense itching and a characteristic rash pattern. Treatment typically involves prescription medications to kill the mites and their eggs.

No, it is not safe or sanitary to perform a hair service on a client with head lice. The client should be referred to a specialist for proper treatment and once the head lice infestation is fully resolved, then a hair service can be carried out.

Lice can lay up to six eggs per day, typically in the hair of their host. These eggs hatch within 7-10 days, leading to rapid reproduction and infestation if left untreated.

Parasite control is important on livestock farms to prevent diseases and maintain animal health. Parasites can cause significant economic losses, reduce productivity, and lead to poor growth and reproduction in livestock. Implementing parasite control measures helps ensure the welfare of the animals and the sustainability of the farm operation.

Yes, heat can be an effective way to kill lice. Using a hair dryer on high heat or washing clothes and bedding in hot water can help eliminate lice and their eggs. However, it's important to combine heat treatment with other methods for comprehensive lice removal.
