Mark each statement as true or false. Rewrite the false statements to make them true by changing the underlined word(s).


__________ Trichomonas vaginalis is the most common parasitic protozoan of humans in the industrialized world.

Verified step by step guidance

1. Step 1: Understand the statement: 'Trichomonas vaginalis is the most common parasitic protozoan of humans in the industrialized world.' This statement is about the prevalence of a specific parasitic protozoan in humans.
2. Step 2: Recall that Trichomonas vaginalis is indeed a common parasitic protozoan, but it is most prevalent in sexually transmitted infections worldwide, not specifically limited to the industrialized world.
3. Step 3: Determine if the statement is true or false. Since Trichomonas vaginalis is the most common parasitic protozoan globally, not just in the industrialized world, the statement as written is false due to the phrase 'in the industrialized world.'
4. Step 4: To correct the statement, replace 'in the industrialized world' with 'worldwide' or 'globally' to accurately reflect the prevalence of Trichomonas vaginalis.
5. Step 5: The corrected statement would read: 'Trichomonas vaginalis is the most common parasitic protozoan of humans worldwide.'

Key Concepts

Parasitic Protozoa

Parasitic protozoa are single-celled eukaryotic organisms that live on or inside a host, often causing disease. Understanding their biology and life cycle is essential to identify common human parasites like Trichomonas vaginalis.

Trichomonas vaginalis

Trichomonas vaginalis is a flagellated protozoan parasite that causes trichomoniasis, a common sexually transmitted infection. It primarily infects the urogenital tract and is notable for being one of the most prevalent parasitic protozoa in humans.

Epidemiology of Parasitic Infections in Industrialized Countries

Epidemiology studies the distribution and determinants of diseases in populations. In industrialized countries, the prevalence of parasitic protozoan infections varies, with some parasites being more common than others due to factors like sanitation and healthcare access.
