Which vector is involved in sylvatic cycle of Trypanosoma cruzi?

Which vector is involved in sylvatic cycle of Trypanosoma cruzi?

In the vector-borne transmission of Chagas disease, approximately 150 species of triatomine bugs are potential vectors for the parasite Trypanosoma cruzi.

What is the incubation period for Chagas disease?

After the incubation period of 1 to 2 weeks, infected patients enter the acute phase of Chagas disease. Transfusion- and transplant-associated cases may have a longer incubation period, sometimes up to 120 days.

How does Trypanosoma cruzi reproduce?

cruzi. In the triatomine bug (Triatoma infestans) the parasite goes into the epimastigote stage, making it possible to reproduce. After reproducing through binary fission, the epimastigotes move onto the rectal cell wall, where they become infectious.

What does sylvatic cycle involve?

The jungle (sylvatic) cycle involves transmission of the virus between non-human primates (e.g., monkeys) and mosquito species found in the forest canopy. The virus is transmitted by mosquitoes from monkeys to humans when humans are visiting or working in the jungle.

What disease is caused by Trypanosoma cruzi?

Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors and is found only in the Americas (mainly, in rural areas of Latin America where poverty is widespread). Chagas disease (T. cruzi infection) is also referred to as American trypanosomiasis.

How Trypanosoma cruzi replicates in the host?

Trypanosoma cruzi replication in the mammalian host Flagellated infective forms of the parasite (trypomastigotes) invade mammalian host cells (I) and differentiate into round intracellular parasites (amastigotes) (II), which replicate by binary fission in the cytoplasm (III).

How does Trypanosoma Gambiense reproduce?

Trypanosoma gambiense reproduces asexually by longitudinal binary fission. Sexual reproduction is not known in this species.

What is the life cycle of Trypanosoma Gambiense?

Trypanosoma gambiense is digenetic; i.e., it completes its life cycle in two hosts. The primary or definitive host is man. The mammals, like pigs, buffaloes, antelopes often act as reservoir hosts harbouring the parasite. The intermediate host is blood sucking insect called tsetse fly (Glossina palpalis).

What is an epizootic cycle?

These infected animals and their fleas serve as long-term reservoirs for the bacteria. This is called the enzootic cycle. Occasionally, other species become infected, causing an outbreak among animals, called an epizootic. Humans are usually more at risk during, or shortly after, a plague epizootic.

Which mosquito borne diseases have a known sylvatic life cycle involving a primate?

For dengue, chikungunya, Zika and yellow fever viruses, sylvatic (forest) transmission cycles also exist in some regions and involve non-human primates and forest-dwelling mosquitoes.

What type of disease does Trypanosoma cruzi cause?

What is Chagas disease? Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors and is found only in the Americas (mainly, in rural areas of Latin America where poverty is widespread).
