Vibrio alginolyticus

Vibrio alginolyticus 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 alginolyticus rather than just read about it. In short: Vibrio alginolyticus is a Gram-negative marine bacterium. It is medically important since it causes otitis and wound infection.

Key takeaways

Vibrio alginolyticus 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 alginolyticus to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Vibrio alginolyticus from memory before moving on to harder problems.

Reference excerpt

Vibrio alginolyticus is a Gram-negative marine bacterium. It is medically important since it causes otitis and wound infection. It is also present in the bodies of animals such as pufferfish, where it is responsible for the production of the potent neurotoxin, tetrodotoxin. Vibrio alginolyticus are commonly found in aquatic environments. Some strains of V. alginolyticus are highly salt tolerant and commonly found in marine environment. S.I. Paul et al. (2021) isolated and identified many strains of Vibrio alginolyticus from nine marine sponges of the Saint Martin's Island Area of the Bay of Bengal, Bangladesh. V. alginolyticus was first identified as a pathogen of humans in 1973. It occasionally causes eye, ear, and wound infections. It is a highly salt-tolerant species and can grow in salt concentrations of 10%. Most clinical isolates come from superinfected wounds that become contaminated at the beach. Tetracycline is typically an effective treatment. V. alginolyticus is a rare cause of bacteremia in immunocompromised hosts.

Biochemical characteristics of V. alginolyticus Colony, morphological, physiological, and biochemical characteristics of Vibrio alginolyticus are shown in the Table below.

Worked examples

Example 1 — a first encounter with Vibrio alginolyticus

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

In research: Vibrio alginolyticus 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 alginolyticus 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 alginolyticus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 1961, Gammaproteobacteria stubs, Marine microorganisms, so understanding it makes those chapters shorter.
In everyday life: Look for Vibrio alginolyticus 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.
