Alphacoronavirus 1

Alphacoronavirus 1 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 Alphacoronavirus 1 rather than just read about it. In short: Alphacoronavirus suis, also called Alphacoronavirus 1, is a species of coronavirus that infects cats, dogs and pigs. It includes the virus strains feline coronavirus, canine coronavirus, and transmissible gastroenteritis virus.

Key takeaways

Alphacoronavirus 1 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Alphacoronavirus 1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Alphacoronavirus 1 from memory before moving on to harder problems.

Reference excerpt

Alphacoronavirus suis, also called Alphacoronavirus 1, is a species of coronavirus that infects cats, dogs and pigs. It includes the virus strains feline coronavirus, canine coronavirus, and transmissible gastroenteritis virus. It is an enveloped, positive-strand RNA virus which is able to enter its host cell by binding to the APN receptor. Member viruses were first recognised as viruses that caused transmissible gastroenteritis in pigs in 1965. It was originally named porcine transmissible gastroenteritis virus in 1976. After subsequent discovery of canine coronavirus in dogs and feline coronavirus in cats, the three virus species were merged into a single species in 2009. The strain canine coronavirus-HuPn-2018 has been identified in a small number of human cases.

Discovery In the mid-1940s there was an outbreak of pig disease in US, called transmissible gastroenteritis, which was characterised mainly by diarrhoea and vomiting. It was suspected to be a viral infection and was highly fatal among young pigs. Leo P. Doyle and L. M. Hutchings reported the case in the Journal of the American Veterinary Medical Association in 1946. The virus was identified and isolated by A. W. McClurkin in 1965. The International Committee for the Nomenclature of Viruses (ICNV, later renamed International Committee on Taxonomy of Viruses, ICTV, in 1975) accepted the scientific named Transmissible gastro-enteritis virus of swine in its first report in 1971, but renamed it Porcine transmissible gastroenteritis virus (PTGV) in its second report in 1976. There was another case of coronavirus infection in cats in 1966. The virus caused inflammation of the abdomen (peritonitis) and was highly fatal. The virus was identified in 1968, and was named as Feline infectious peritonitis virus by ICTV in 1991. It was again renamed Feline coronavirus in 1999. In 1974 there was an outbreak of viral infection among US military dogs. The virus was identified as a coronavirus and the formal name Canine coronavirus was adopted by ICTV in 1991. As the molecular and antigenic relationship of the three viruses were later established in the late 1980s, ICTV merged them into a single species Alphacoronavirus 1 in 2009, and in 2024 the species was renamed Alphacoronavirus suis.

Worked examples

Example 1 — a first encounter with Alphacoronavirus 1

Start with the simplest possible case. Write down what Alphacoronavirus 1 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 Alphacoronavirus 1 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 Alphacoronavirus 1 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 Alphacoronavirus 1

In research: Alphacoronavirus 1 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 Alphacoronavirus 1 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: Alphacoronavirus 1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alphacoronaviruses, Animal viral diseases, Cat diseases, so understanding it makes those chapters shorter.
In everyday life: Look for Alphacoronavirus 1 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 Alphacoronavirus 1 in simple terms?

Why does Alphacoronavirus 1 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 Alphacoronavirus 1?

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.
