Staphylococcus: meaning, definitions and examples
ðŸ¦
Staphylococcus
[ stæfɪləˈkɒkəs ]
microbiology
Staphylococcus is a genus of bacteria known for its round shape and tendency to form clusters resembling grapes. These bacteria are commonly found on the skin and in the respiratory tract of humans and animals, often without causing disease. However, certain species can be pathogenic, leading to infections such as boils, pneumonia, and sepsis.
Synonyms
staph, staphylococci
Examples of usage
- Staphylococcus aureus is known for causing skin infections.
- The lab confirmed the presence of Staphylococcus in the sample.
- Hand hygiene can reduce the risk of Staphylococcus transmission.
Etymology
The term 'Staphylococcus' originates from the Greek words 'staphyle,' meaning a bunch of grapes, and 'kokkos,' meaning berry. This reflects the bacteria's characteristic clustering shape when viewed under a microscope. The genus was first described in the late 19th century by the microbiologist Sir Alexander Ogston, who investigated the role of these bacteria in infections. Over the years, studies have revealed the diverse nature of the Staphylococcus genus, including both non-pathogenic and pathogenic species, leading to increased understanding of their role in human health and disease. Today, Staphylococcus remains a significant focus in medical microbiology due to its association with a variety of infections and its ability to develop resistance to antibiotics.
