Identify the portals of entry for Trypanosoma cruzi, Hantavirus, and cytomegalovirus.
To review:
Streptococcal infection in the cardiovascular system and predict the entry of pathogens like Trypanosoma cruzi, Hantavirus, and cytomegalovirus into the pericardium.
Introduction:
Strep throat is a common infection caused by Streptococcal bacteria. Cytomegalovirus infects individuals with weak immune system and widely cause infections in infants. Trypanosoma cruzi cause Chagas disease and Hanta virus cause infection in pulmonary alveoli.
Explanation of Solution
Diagram:
Streptococcal infection mainly causes strep throat. Through blood vessels, the pathogen ultimately reaches the heart and cause infection in the cardiovascular system.
Cytomegalovirus is a form of herpes virus. It infects the person with weak immune system and it remains in humans throughout the life time. Mostly, it infects pregnant women and infants. This infection may also lead to miscarriages. Some of the symptoms are tiredness, fever, and fatigue.
Chagas disease is caused by Trypanosoma cruzi. This protozoa enter into the blood stream and infects other cells. Triatomine bug is an insect vector which helps in the transmission of disease. Swelling of the eyelid is a typical sign of Chagas disease. In the chronic phase of the disease, the infected individual develops symptoms like enlargement of the ventricles. This ultimately results in heart failure.
Hantavirus, also called as orthohantavirus, is a single stranded RNA virus that infects the humans. It mainly infects the alveoli of the lungs. This condition is known as a Hantavirus pulmonary syndrome. Hantavirus also has a tendency to affect the kidneys and heart, and ultimately hinder the proper functioning of these organs.
Trypanosoma cruzi, Hantavirus and cytomegalovirus infects the cardiovascular system and their entries are shown in the diagram.

PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population?

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
