What is the Difference Between Strep and Staph Infection?
🆚 Go to Comparative Table 🆚Strep and staph infections are both caused by different types of bacteria and can lead to various health issues. Here are the main differences between the two:
- Source of infection: Strep infections, or streptococcus, are most commonly found in the respiratory system, including the throat, and are responsible for conditions like strep throat. Staph infections, or staphylococcus, are skin infections that typically result from surgery or an open wound.
- Bacterial structure: Strep bacteria are spherical and usually grow in chains, while staph bacteria are round and form clusters.
- Toxin production: Group A streptococci are known to produce toxins that can damage tissue and cause inflammation, whereas Staphylococcus aureus produces toxins that can cause various infections, including skin infections, pneumonia, and sepsis.
- Infection location: Strep infections typically affect the respiratory system, including the throat, and can cause conditions like impetigo and cellulitis. Staph infections, on the other hand, are skin infections that can range from mild conditions like pimples and boils to more severe infections like pneumonia and sepsis.
- Transmission: Strep infections can be transmitted through direct person-to-person contact or indirectly through contact with contaminated items. Staph infections can also be transmitted through direct contact with an infected person or indirectly through contact with a contaminated object.
Both strep and staph infections can be diagnosed through a swab of the infected site or, depending on the site of the infection, via blood or urine testing. Most mild cases of strep and staph infections can go away on their own or with at-home remedies like rest, fluid intake, and keeping the infection site clean. However, if symptoms don't improve within a few days, start to worsen, or are accompanied by a high fever or nausea, it is essential to consult a doctor.
Comparative Table: Strep vs Staph Infection
Here is a table comparing the differences between strep and staph infections:
Characteristic | Strep Infection | Staph Infection |
---|---|---|
Causative Bacteria | Streptococcus bacteria (e.g., Streptococcus pneumoniae, Viridians Streptococci, group A, group B, and group D Streptococci) | Staphylococcus bacteria (e.g., Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus saprophyticus, and Staphylococcus Lugdunensis) |
Bacterial Arrangement | Chains of round cells | Grape-like clusters |
Division | Single linear direction | Multiple axes |
Common Diseases | Strep throat, scarlet fever, impetigo, toxic shock syndrome, cellulitis, necrotizing fasciitis (flesh-eating disease), sinusitis, blood infections, pneumonia, and meningitis in newborns | Food poisoning, bacterial conjunctivitis, skin diseases, community-acquired meningitis, surgical site infection, wound infection, impetigo, cellulitis, and toxic shock syndrome |
Infection Site | Commonly found in the respiratory system, including the throat | Often found on the skin, but can cause infections in various parts of the body |
Diagnosis | Doctors can diagnose through a swab of the infected site or, depending on the site of the infection, via blood or urine testing | Doctors can diagnose through a swab of the infected site or, depending on the site of the infection, via blood or urine testing |
Treatment | Both infections can be treated with specific antibiotics | Both infections can be treated with specific antibiotics |
Both strep and staph infections are bacterial infections caused by gram-positive bacteria, but they belong to different family classifications and affect different body areas.
