No, parasites can be both invertebrates and vertebrates. Some examples of vertebrate parasites include tapeworms and lice, while examples of invertebrate parasites include ticks and fleas.
Some examples of parasites that kill their hosts include parasitic wasps, liver flukes, and malaria parasites. When these parasites kill their hosts, it can disrupt the balance of the ecosystem by reducing the population of the host species. This can have cascading effects on other species that rely on the host for food or other resources, potentially leading to changes in the overall biodiversity and functioning of the ecosystem.
Parasites can be prokaryotic or eukaryotic. Prokaryotic parasites include bacteria that cause infections like Salmonella and E. coli. Eukaryotic parasites include protozoa such as Plasmodium (which causes malaria) and helminths like tapeworms.
Parasites commonly found in cattle include internal parasites like gastrointestinal worms (e.g., Ostertagia, Haemonchus) and protozoa such as Cryptosporidium and Eimeria. External parasites include ticks, lice, and flies, which can cause skin irritation and transmit diseases. These parasites can significantly impact cattle health, growth, and productivity if not effectively managed through veterinary care and proper husbandry practices.
Endoparasites are parasites that live inside their host's body. These parasites can reside in the digestive tract, blood vessels, tissues, or organs of their host. Common examples include tapeworms, nematodes, and flukes.
Worms are normally not external parasites, but internal parasites. External parasites include different arthropod species like ticks, fleas, lice, mosquitos....
Metronidazole is an antibiotic used to treat anaerobic bacteria and parasites. These parasites include giardia lamblia and amoeba. It also treats trichomonas vaginal parasites.
Parasites are commonly found on cats and dogs.
Infectious diseases caused by fungi include candidiasis, aspergillosis, and ringworm. Infectious diseases caused by parasites include malaria, toxoplasmosis, and giardiasis.
The two types of parasites are:- 1) Ectoparasites :- Parasites which live on the external surface of the host are called ectoparasites. Examples :- 1. Animals - Ticks, Mosquitoes, Bed-bugs, Head louse, Leeches etc. 2. Plants - Cuscuta, Loranthus 2) Endoparasites :- Parasites living within the host are called endoparasites. Examples :- 1. Animals - Liverfluke, Tapeworm, Ascaris, Plasmodium 2. Plants - Many fungi.
Flagellated parasites include organisms such as Giardia lamblia, Trichomonas vaginalis, and Trypanosoma brucei, which use whip-like structures called flagella for movement. These parasites can cause infections in humans and other animals, resulting in diseases such as giardiasis, trichomoniasis, and African sleeping sickness.
Some examples of density-dependent population regulation factors include competition for resources, predation, disease transmission, and stress from overcrowding. As population density increases, these factors can have a greater impact on the population size and dynamics.
