What are Staphylococcus?

Staphylococcus or more commonly known as staph is a term used to describe the bacteria that results in the formation of many severe diseases in human beings. Due to the infestation of staph, some diseases that are caused tend to be directly infectious in nature.

There are some toxins that are produced by the bacteria which are specifically harmful. Impetigo, boils, toxic shock syndrome as well as cellulitis are some examples of different diseases that can be caused due to the infestation of staphylococcus. Methicillin-resistant Staphylococcus aureus, also known as MRSA, is resistant to penicillin.

Staphylococcus Causes: What Causes These Infections? 

  • Staphylococcus can be defined as the bacterial group or germ/microbe group that results in various infectious diseases that affect the different tissues in the bodies of organisms. More commonly called Staph, these bacteria are of a serious kind and can cause mild to potentially fatal ailments in people. Staphylococcus epidermidis is one of the main examples of the bacteria that cause such infectious diseases in people. 

  • The name of the bacteria is derived from the Greek terms staphyle and kokkos that translate to grapes and berries. The name has been selected for the bacteria because this is what it looks like under the microscope. 

  • There are about 30 different types of staphylococcus bacteria that can harm humans. However, the most effective and dangerous one would be the staphylococcus aureus. These bacteria mostly reside on the skin and the nose of about 30% of adults who are healthy and in about 25% of people belonging to the medical industry. In the majority of the cases, the bacteria don’t tend to form any particular disease. But in some cases, an injury or a cut in the skin can cause the bacteria to penetrate all the defence mechanisms of the body and it can result in an infection. The groups of people who are always at risk due to the coagulase negative staphylococcus include newborn infants, drug users, and patients who have had certain surgical incisions made in their bodies. 

Who is at Risk from Staphylococcus Bacteria? 

  • Although there are some groups of people who tend to develop a higher level of risk for a staphylococcus infection, it can happen to anyone. Most people, such as newborn infants, women who are breastfeeding, and people that have certain chronic conditions, are always at risk. These are the people who don’t have a strong immune system and hence are prone to diseases. 

  • People who have diseases such as cancer, diabetes, lung diseases, and vascular diseases are also at high risk. Apart from that, people who have been injecting drugs and have undergone surgery can also develop the infection from staphylococcus haemolyticus. 

Can Staphylococcus Bacteria Cause Contagious Infections? 

  • The staphylococcus bacterial infection can be contagious until the resolution of the infection is complete. If someone comes in contact directly with a sore that is infected, it can lead to them developing an infection. People can also have an infection from touching personal care products such as razors and bandages. However, casual forms of contact such as hugging and kissing don’t really pose much of a risk of transmission. The person shouldn’t come in contact directly with the area that is infected. 

  • There are certain types of infections related to the organisms that tend to cause toxic shock syndrome and food poisoning in people. These bacteria are the ones that cause the diseases with the production of a particular type of toxin. However, the toxin is not that contagious in nature. 

How Long Does the Incubation Period Last for Staphylococcus Aureus Infection? 

There are so many types of different infections that can arise from the bacteria already present in the skin and the mucous membrane. Hence, the incubation period for such cases is not known. However, in other cases, when the infection has spread from another person, the period lasts for about 10 days in total. 

What Are Some Symptoms And Signs of Infection From Staphylococcus Bacteria? 

If the staphylococcus bacteria affect the skin, it will form pus, which is collected and forms an abscess, furuncle, or a boil of some sort. Some of the symptoms that are seen in the case of a staph infection include redness, swollen skin, high fever, low blood pressure, and painful skin. In case a person identifies these symptoms, they can make an appointment with their doctor and get proper staphylococcus aureus treatment.
