Parasitology is the branch of biology that studies parasites, their hosts, and the interactions between them. It encompasses various aspects, including:
Overall, parasitology is essential for understanding the biology of parasites and their impact on health and ecosystems.
Ancylostoma duodenale Ancylostoma duodenale is a species of the Ancylostoma genus. The hookworm of the Old World is a parasitic nematode worm. It matures and reproduces in the small intestines of humans, cats, and canines. Ancylostoma duodenale and Necator americanus are the two hookworm species commonly cited as the cause of hookworm infection in humans. … Read more
What is Cysticercosis? Clinical manifestations of Cysticercosis Cysticercosis is a parasitic infection caused by the larval stage of the tapeworm Taenia solium. The clinical manifestations of cysticercosis depend on the location of the cysticerci (larval stage) within the body. It’s worth noting that not all patients with cysticercosis will experience symptoms. Asymptomatic cysticercosis is often … Read more

Fasciola Hepatica Life Cycle of Fasciola Hepatica Fasciola hepatica completes its life cycle in two hosts. The definitive or primary host is a sheep or cow, while the intermediate or secondary host is a small of the genus Limnaea. Its life cycle consists of a number of larval stages that reproduce asexually (polyembryony). Copulation, Fertilization … Read more
Strongyloides stercoralis Distribution of Strongyloides stercoralis Habitat of Strongyloides stercoralis Morphology of Strongyloides stercoralis There are two different species of Strongyloides stercolaris: parasitic and free-living. The females are easily found during the parasite phase, but not the males. Parasitic female Parasitic males Eggs Larva The larva of S. Stercoratis is of two types: 1. Rhabditiform larva (first stage larva) 2. … Read more
What is Loa loa? Epidemiology of Loiasis Morphology of Loa loa Loa loa Life Cycle The life cycle of Loa loa is a complex process involving two hosts: humans as the definitive host and Chrysops flies as the intermediate host. The cycle begins with the transmission of the parasite through the bite of an infected … Read more
What is Schistosoma haematobium? Kingdom: Animalia Phylum: Platyhelminthes Class: Trematoda Order: Diplostomida Family: Schistosomatidae Genus: Schistosoma Species: S. haematobium Characteristics of Schistosoma haematobium Structure of Schistosoma haematobium Geographic Distribution Habitat Life cycle of Schistosoma haematobium Pathogenicity of Schistosoma haematobium Hosts of Schistosoma haematobium Schistosoma haematobium is the parasite responsible for schistosomiasis. Schistosoma haematobium’s intermediate host … Read more
Taenia solium is unique among Taenia species in that it can use its definitive host (human) as an intermediate host. The oncosphere larva can infect a human host via external autoinfection, in which feces-expelled eggs are ingested orally. Internal autoinfection, in which a larva can infect its host without being expelled via feces, has not … Read more
Fascioliasis is an infectious disease caused by Fasciola parasites, which are flatworms referred to as liver flukes. The adult (mature) flukes are found in the bile ducts and liver of infected people and animals, such as sheep and cattle. In general, fascioliasis is more common in livestock and other animals than in people.
Schistosomiasis also termed snail fever or bilharzia is a disease caused by parasitic flatworms called schistosomes. Infection with Schistosoma mansoni, S. haematobium, and S. japonicum causes illness in humans; less commonly, S. mekongi and S. intercalatum can cause disease.
