Vibrio ichthyoenteri

Vibrio ichthyoenteri 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 Vibrio ichthyoenteri rather than just read about it. In short: Vibrio ichthyoenteri is a species of marine bacteria within the genus Vibrio. This species was first isolated from olive flounder(Paralichthys olivaceus) in Japan and has since been recognized as an important bacterial pathogen in marine aquaculture.

Key takeaways

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

Reference excerpt

Vibrio ichthyoenteri is a species of marine bacteria within the genus Vibrio. This species was first isolated from olive flounder(Paralichthys olivaceus) in Japan and has since been recognized as an important bacterial pathogen in marine aquaculture.

Characteristics Vibrio ichthyoenteri are gram-negative, facultatively anaerobic bacteria that are motile through a single polar flagellum. Similar to other members of the genus, this species is glucose fermenting, oxidase-positive, catalase-positive, and susceptible to the vibriostatic agent O/129. Unlike most other Vibrio, this species lacks chitinase activity.

Aquaculture Vibrio ichthyoenteri is a notable cause of bacterial infection in aquaculture, particularly flounder and turbot. V. ichythyoenteri infections are unique in that intestinal infection only develops in larval fish. Infected fish may present with intestinal necrosis, ascites, and sepsis. Antibiotics are an effective treatment method, although antibiotic resistance in Vibrionaceae are emerging. Vaccines are currently being investigated as a potential preventative measure against V. icthyoenteri infections.

Worked examples

Example 1 — a first encounter with Vibrio ichthyoenteri

Start with the simplest possible case. Write down what Vibrio ichthyoenteri 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 Vibrio ichthyoenteri 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 Vibrio ichthyoenteri 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 Vibrio ichthyoenteri

In research: Vibrio ichthyoenteri 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 Vibrio ichthyoenteri 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: Vibrio ichthyoenteri is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 1996, Gram-negative bacteria, Marine microorganisms, so understanding it makes those chapters shorter.
In everyday life: Look for Vibrio ichthyoenteri 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.
