What is Spirometra SPP?

Spirometra is a genus of pseudophyllid cestodes that reproduce in canines and felines, but can also cause pathology in humans if infected. As an adult, this tapeworm lives in the small intestine of its definitive host and produces eggs that pass with the animal’s feces.

What causes sparganosis?

Sparganosis is a human parasitation caused by the plerocercoid larvae of tapeworms belonging to the Spirometra genus. Humans acquire the disease either orally or by active penetration of the larvae.

Which form of Spirometra is seen in man?

Tapeworms of the genus Spirometra are of medical interest in that the larval form is occasionally found as a tissue parasite in man causing the infection known as sparganosis.

What is the difference between cysticercosis and Taeniasis?

What is the difference between cysticercosis and taeniasis? Remember, taeniasis is the infection of a human with the adult form of the beef or pork tapeworm. Cysticercosis is the infection of a human with the larval stage of the pork tapeworm, T. solium, only.

How is Spirometra transmitted?

Spirometra spp. have indirect life cycles that require two intermediate hosts before becoming infectious to the definitive host. Adult Spirometra spp. in the small intestine of infected cats or dogs release operculate eggs from a midventral genital pore; these eggs are then passed in the feces.

What is the meaning of sparganosis?

Sparganosis is a parasitic infection caused by the plerocercoid larvae of the genus Spirometra including S. mansoni, S. ranarum, S. mansonoides and S. erinacei.

What type of infection is sparganosis?

Sparganosis is infection with larvae of Spirometra species or Sparganum proliferum tapeworms. The four main intestinal cestode pathogens of humans are Taenia saginata ( beef tapeworm) Taenia solium ( pork tapeworm) Hymenolepis… read more .

How do humans get Spirometra?

Diphyllobothroid tapeworm under the genus Spirometra is the causative agent. Humans can be infected through the consumption of contaminated water or meat from intermediate hosts or through topical application of raw, contaminated poultices to eyes and open wounds.

Can I get Spirometra from my cat?

Public Health Considerations. Dogs and cats infected with Spirometra spp. do not create an immediate zoonotic risk because the stage (coracidium) that hatches from the eggs shed in pet feces are infectious only to the copepod first intermediate host. People who inadvertently ingest Spirometra spp.

What is the significance of cysticercosis?

Cysticercosis is a parasitic tissue infection caused by larval cysts of the tapeworm Taenia solium. These larval cysts infect brain, muscle, or other tissue, and are a major cause of adult onset seizures in most low-income countries.

How do you treat Spirometra?

Infections with Spirometra sp in dogs and cats can be treated with praziquantel at 7.5 mg/kg, PO, for 2 consecutive days. Spirometra sp infections in cats can also be treated with a single dose of praziquantel at 30 mg/kg, SC, IM, or PO. Mebendazole at 11 mg/kg, PO, has also been successful.

What does sparganosis look like?

The nodules usually itch, swell, turn red, and migrate, and are often accompanied by painful edema. Seizures, hemiparesis, and headaches are also common symptoms of sparganosis, especially cerebral sparganosis, and eosinophilia is a common sign.

What is plerocercoid larva?

Medical Definition of plerocercoid : the solid elongate infective larva of some tapeworms especially of the order Pseudophyllidea usually occurring in the muscles of fishes.

What is the morphology of Taenia Saginata?

Taenia saginata has a very distinctive morphology. This flatworm can grow in length from 4 to 12 meters long and 2 milimeters in diameter consisting of a scolex, neck, and strobila. Adults possess a flat, ribbon-like body shape that is important for absorbing nutrients from its hosts’ intestine.

What are the characteristics of Taenia?

Characteristics: Taenia solium is a tapeworm of the class cestoidea, order cyclophyllidea, and family Taeniidae 1. Adult worm: Mature worms are found only in humans. Adult worm grows to approximately 2-4 m. Scolex has 4 suckers and the rostellum has two crowns of horns.

What is the scolex of Spirometra mansonoides?

The scolex of Spirometra mansonoides lacks suckers but instead possesses two shallow longitudinal grooves called bothria (Mueller, 1935). It varies in diameter from 0.2 mm to almost 0.5 mm with bothria approximately 1.0 mm in length. The bothria are shallow, broad and flat bottomed.

What are the hosts of Spirometra mansonoides?

Domestic and wild felids serve as the principal definitive hosts for Spirometra mansonoides, although dogs and racoons may harbor the adult cestodes (Mueller, 1974). In a survey of animals from Louisiana in the United States, plerocercoids were found in two amphibian, eight reptilian and three mammalian species.

What is the pathophysiology of Spirometra?

Adult Spirometra spp. in the small intestine of infected cats or dogs release operculate eggs from a midventral genital pore; these eggs are then passed in the feces. When the egg contacts water, a ciliated embryo (coracidium) hatches and is ingested by a copepod, the first intermediate host,…

What is the life cycle of Spirometra spp?

Spirometra spp. have indirect life cycles that require two intermediate hosts before becoming infectious to the definitive host. Adult Spirometra spp. in the small intestine of infected cats or dogs release operculate eggs from a midventral genital pore; these eggs are then passed in the feces.
