Novymonas

Novymonas 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 Novymonas rather than just read about it. In short: Novymonas esmeraldas is a protist and member of flagellated trypanosomatids. It is an obligate parasite in the gastrointestinal tract of a bug, and is in turn a host to symbiotic bacteria.

Key takeaways

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

Reference excerpt

Novymonas esmeraldas is a protist and member of flagellated trypanosomatids. It is an obligate parasite in the gastrointestinal tract of a bug, and is in turn a host to symbiotic bacteria. It maintains strict mutualistic relationship with the bacteria as a sort of cell organelle (endosymbiont) so that it cannot lead an independent life without the bacteria. Its discovery in 2016 suggests that it is a good model in the evolution of prokaryotes into eukaryotes by symbiogenesis. The endosymbiotic bacterium was identified as member of the genus Pandoraea.

Discovery Novymonas esmeraldas was discovered from a bug, Niesthrea vincentii, from Ecuador. The bug was collected in July 2008 near Atacames in Esmeraldas Province, hence, the protist bears the species name. The genus name is after Frederick George Novy, an American bacteriologist and parasitologist who pioneered studies of insect trypanosomatids, and described in 1907 the first known symbiont-harbouring trypanosomatid, later named Strigomonas culicis.

Biology

Protist Novymonas esmeraldas spends it life cycle in the intestine (hindgut) of the bug, Niesthrea vincentii. During its life cycle it exists in two morphological forms, free-swimming promastigote and sedentary choanomastigote. Promastigotes are elongated and measure about 10.9 to 18 μm in length and about 1.3 to 4.8 μm in width. They bear a single flagellum in front that is 7.8 to 19.5 μm long. Choanomastigotes are more spherical in shape measuring 4.5 to 9.7 μm long and 2.8 to 6.4 μm wide. The flagellum is longer measuring 8.6 and 20.4 μm. The nucleus is centrally located, and in front of it is the kinetoplast. The kinetoplast is arranged in a compact disk which measures between 553 and 938 nm in diameter and 114 to 213 nm in cross section.

Bacterium The endosymbiont is a bacterium classified as (Candidatus) Pandoraea novymonadis that belongs to Gram-negative rod-shaped β-proteobacteria in the family Burkholderiaceae. Unlike in other symbiont-harbouring trypanosomatids such as Strigonomas culicis, Kentomonas sorsogonicus, and Angomonas deanei, the division of the endosymbiont is not synchronized with the host. Novymonas cells can bear a different number of the endosymbionts, and some do not have the bacteria at all. This indicates that the symbiosis in Novymonas is more recent than in the case of the other endosymbiont-bearing trypanosomatids. However, in contrast to its related free-living bacteria, P. novymonadis has highly reduced genome, less genes and lower GC contents.

Worked examples

Example 1 — a first encounter with Novymonas

Start with the simplest possible case. Write down what Novymonas 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 Novymonas 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 Novymonas 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 Novymonas

In research: Novymonas 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 Novymonas 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: Novymonas is common in secondary-school and first-year university syllabi. It links to neighbouring topics Endosymbiotic events, Euglenozoa genera, Kinetoplastids, so understanding it makes those chapters shorter.
In everyday life: Look for Novymonas 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 Novymonas in simple terms?

Novymonas esmeraldas is a protist and member of flagellated trypanosomatids. It is an obligate parasite in the gastrointestinal tract of a bug, and is in turn a host to symbiotic bacteria.

Why does Novymonas 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 Novymonas?

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.
