Klossiella

Klossiella 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 Klossiella rather than just read about it. In short: Klossiella is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect the renal tract of mammals and intestinal tract of snakes.

Key takeaways

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

Reference excerpt

Klossiella is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect the renal tract of mammals and intestinal tract of snakes. The type species is Klossiella muris.

History The first member of this genus was identified by Smith in 1889 in the kidney of a white mouse. An expanded study of this parasite was later published by Smith and Johnson in 1902 where they suggested the name Klossiella muris.

Taxonomy Currently there are 17 species recognised in this genus. All except one (Klossiella boae) infect the renal tracts of mammals.

Description This genus is unusual in having only a single host in its life cycle. The parasite is ingested and within the gut sporozoites escape from the sporocyst and invade the blood stream. Upon reaching the kidney, within the epithelium of the kidney the sporozoite undergoes merogony followed by gametogony and sporogony. It produces polysporocystic oocysts without a resistant oocyst wall. The resistant sporocysts are then shed in the urine. The oocysts are subspherical, smooth and measure 22-24 μm by 20-21 μm.

Clinical K. boae occurs both in the intestine and the kidney of the boa constrictor. It may cause anorexia, restlessness, hemorrhagic enteritis and intussusception.

Host records K. bettongiae - Tasmanian bettong (Bettongia gaimardi) K. beveridgei - spectacled hare-wallaby (Lagorchestes conspicillatus) K. boae - boa constrictor (Boa constrictor) K. callitris - western grey kangaroo (Macropus fuliginosus) K. cobayae - guinea pig (Cavia porcellus) K. dulcis n.sp. - sugar glider (Petaurus breviceps) K. equi - horse (Equus ferus caballus) K. hydromyos - Australian water rat (Hydromys chrysogaster) K. mabokensis - African murid (Praomys jsoni) K. muris - mouse (Mus musculus) K. quimrensis - western barred bandicoot (Perameles bougainville) K. rufi - red kangaroo (Macropus rufus) K. rufogrisei - Bennett's wallaby (Macropus rufogriseus) K. schoinobatis - petaurid greater glider (Petauroides volans) K. serendipensis - swamp wallaby (Wallabia bicolor) K. tejerai - opossum (Didelphis marsupialis) K. thylogale - Tasmanian pademelon (Thylogale billardierii)

Note This genus has also been found in the kidneys of bats but the species was not identified.

Worked examples

Example 1 — a first encounter with Klossiella

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

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

Klossiella is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect the renal tract of mammals and intestinal tract of snakes.

Why does Klossiella 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 Klossiella?

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.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Klossiella.
