For which parasite human is intermediate host?
Table 2: Parasite and their intermediate host(s)
|Liver Flukes (Clonorchis, Opisthorchis)||Fish of Cyprinidae family (carps and minnows)|
|Tapeworm (Taenia solium)||Humans, Cow, Pigs|
|Schistosoma mansoni||Freshwater snails (Biomphalaria spp.)|
|Toxoplasma gondii||Many mammals and birds|
How can humans become an intermediate host for parasites?
Humans become an accidental intermediate host after ingesting T. solium eggs shed by a tapeworm carrier. The ova are sticky and are often found on the hands of tapeworm carriers, and transmission usually involves close personal contact.
Which tapeworm has the human as the intermediate host?
solium; cysticercosis results from humans acting as accidental intermediate hosts for the parasite (this role is normally fulfilled by swine).
What parasite has two intermediate hosts?
Like many other parasites, these trematodes have a three host life cycle involving two intermediate hosts and one definitive host.
What is intermediate parasite?
1 : a host which is normally used by a parasite in the course of its life cycle and in which it may multiply asexually but not sexually — compare definitive host.
Which parasite require intermediate host in the life cycle?
Nematodes, trypanosomatids, and Cryptosporidium are examples of parasites with direct life cycles. Parasites with indirect life cycles are characterized by two host stages, which require a definitive host and an intermediate host. The definitive host stage is required for reproduction and the adult life phase.
Which of the following parasite has no intermediate host?
Ascaris lumbricoides (the common roundworm) has no intermediate host. Man acquires infection by directly ingesting Ascaris eggs having the infective second stage- rhabditoid larva, with contaminated food or water.
What is the most common intermediate host?
Snail intermediate hosts of M.
Like all trematodes, Metagonimus requires a snail as an intermediate host. Snails in the genus Semisulcospira are the most common intermediate hosts for M. yokogawai. Figure A: Snail in the genus, Semisulcospira.
Which tapeworm infects cattle as an intermediate host?
Taenia saginata, known as the beef tapeworm, is transmitted to humans in the form of infectious larval cysts found in the meat of cattle, which serve as the parasite’s usual intermediate host.
What are the common hosts of Cestodes?
Echinococcus eggs from dog or fox fur cause human hydatid disease (humans are the intermediate host; canids are the definitive hosts). Reinfection with adult tapeworms is common; second infections with larvae are rare.
