Identify the most infectious and fatal type of malarial parasite:
- Plasmodium ovale
- Plasmodium vivax
- Plasmodium malariae
- Plasmodium falciparum
The Correct Option is D
Solution and Explanation
Plasmodium falciparum is responsible for the majority of severe and life-threatening cases of malaria. It is prevalent in many tropical and subtropical regions, particularly in sub-Saharan Africa. This parasite is known for its ability to rapidly multiply in the bloodstream and cause severe symptoms, leading to complications such as cerebral malaria, organ failure, and death if left untreated.
Compared to other species of Plasmodium, such as Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae, Plasmodium falciparum is considered the most virulent and dangerous. It has developed resistance to certain antimalarial drugs, making treatment more challenging. Prompt and effective treatment is essential to prevent complications and fatalities associated with Plasmodium falciparum infection.
Top Questions on Diseases
- Read the following passage and answer the questions that follow.
In 1981, the health workers of United States of America had become aware of the increased frequency of Kaposi’s sarcoma, cancer of the skin and blood vessels and another disease pneumocystis pneumonia, a respiratory infection caused by a protozoan. Both these diseases were very rare in the general population, but occurred frequently in more severely “immunosuppressed” individuals. This led to the recognition of the immune system disorder that was named Acquired Immune Deficiency Syndrome (AIDS). In 1983, virologists working in the USA and France had identified a causative agent for ’AIDS’, now known as Human Immunodeficiency Virus (HIV). “HIV” follows a set path to attack the human body to cause the disease.
(a) Name the group of cells the HIV attacks after gaining entry into the human body and write the various events that occur within this cell.
(b) Write the expanded form of the diagnostic test used for detecting AIDS. Write the possible treatment available for the disease at present.
(c) Mention any two steps suggested by WHO for preventing the spread of this disease.
(c) “A patient suffering from AIDS does not die of this disease but from some other infection.” Justify the statement. - The vector for dengue fever is:
(c) Name a species of mosquito other than female Anopheles and the disease, for which it carries the pathogen.
- (b) Studying Diseases
- Name this RNA product transcribed from the DNA that subsequently translates into a polypeptide of 400 amino acids. Mention the enzyme responsible for transcribing this type of RNA from the DNA.
