Necator americanus rhabditiform larvae Toxocara canis larvae Strongyloides stercoralis rhabditiform larvae Ancylostoma duodenale filariform larvaeArthrobotrys is saprophytic fungus called -1 nematophagous fungi False O True Plasmodiophora brassicae has different -4 * .modes of nutrition True O False
- Each of the following statements concerning Ascaris lumbricoides is correct* Ascaris lumbricoides can cause pneumonia Ascaris lumbricoides is one of the largest nematode A. lumbricoides is transmitted by ingestion of eggs Both dogs and cats are intermediate hosts of Ascaris lumbricoidesA 5 year-old child was playing in their backyard. Suddenly, the child felt itchiness in his skin and began to scratch his body. Based on laboratory results, it was confirmed that the child was infected with hookworm. Answer the following questions: What possible mode of transmission the parasite has been acquired? Explain why. List all possible effects of parasite on the host. Explain each.What genus of the parasite below belong to: Entamoeba Plasmodium Taenia Ancylostoma Schistosoma
- Water-related activities such as swimming underwater, diving. or other water sports can result in water going up the nose. Promitosis Amebae penetrate the nasal mucosa Trophozoite Flagellated form Amebae migrate to the brain via the olfactory nerves causing primary amebic meningoencephalitis (PAM) in healthy individuals Vector borne parasite Facultative parasite Obligate parasite Ectoparasite Trophozoites in CSF and brain tissue Flagellated forms occasionally in CSF Cyst A=Infective Stage Diagnostic Stage CDC SAFER-HEALTHIER PEOPLE" Observe this life cycle for Naegleria fowleri, an amoebic protozoan also called "the brain eating amoeba". N. fowleri usually completes its entire life cycle by eating bacteria (e.g., in pond water). What is an appropriate term for its relationship with humans?Which of the following organisms penetrates skin, has large terminal spines on its eggs, and is found in urine samples? O Teniea solium Schistosoma haematobium Ancylostoma duodenalee O Ascaris lumbricoidesIs it more beneficial for Neodermata to have one host or two hosts? Neodermatahas two classes: class Trematoda and class Monogenea. Class Trematoda has the subclass Digenea, which has organisms that live through at least two different hosts. An example of this is Fasciola hepatica, the sheep's liver fluke. Class Monogenea has organisms that only need to live through one host. Is it better to have a simple or complex life cycle? Which lives longer? Has more energy? Does more damage or good?
