Laverania

Laverania is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Laverania rather than just read about it. In short: Laverania is a subgenus of the parasite genus Plasmodium. Infection with these species results in malaria.

Key takeaways

Laverania belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Laverania to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Laverania from memory before moving on to harder problems.

Reference excerpt

Laverania is a subgenus of the parasite genus Plasmodium. Infection with these species results in malaria. The subgenus was first described in 1958. The name was first proposed by Welch in 1897 as a genus name for the group now known as Plasmodium but for a variety of reasons the genus name Plasmodium was preferred.

Taxonomy The first non-human primate parasites were described by Eduard Reichenow in Cameroon in 1920. He observed three morphologically distinct Plasmodium parasites in the blood of chimpanzees and gorillas in 1917. These finding were later confirmed by other workers. One species closely resembled P. falciparum and was thought to be the same species. This species was later renamed P. reichenowi. The other two species — P. rhodaini and P. schwetzi — have since been placed in the subgenus Plasmodium. The noticeable differences between P. falciparum and the other known Plasmodium species led to the proposal that it be placed in a separate genus Laverania. This suggestion was not accepted but the proposed name is now used as the subgenus.

Species It has been proposed to rename P. gora and P. gorb as Plasmodium adleri and Plasmodium blacklocki respectively. It has also been proposed that P. billbrayi be considered a junior synonym of P. gaboni.

The full genomes of the seven species are now sequenced and available on PlasmoDB.

Worked examples

Example 1 — a first encounter with Laverania

Start with the simplest possible case. Write down what Laverania claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Laverania before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Laverania ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Laverania

In research: Laverania appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Laverania in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Laverania is common in secondary-school and first-year university syllabi. It links to neighbouring topics Infectious disease stubs, Plasmodium stubs, Plasmodium subgenera, so understanding it makes those chapters shorter.
In everyday life: Look for Laverania outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Laverania in simple terms?

Laverania is a subgenus of the parasite genus Plasmodium. Infection with these species results in malaria.

Why does Laverania matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Laverania?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
