Staphylococcus aureus and Pseudomonas at Children
The Staphylococcus aureus and Pseudomonas are facultative bacteria naturally found on the skin and healthy people mucosa, and also in nature. Most cases, they don't cause infections or cause minor skin infections, when the skin or mucosa have suffered lesions which are the staphylococcus entrance. In some conditions, certain bacteria may penetrate the skin, get into the body and affect the urinary tract, the lungs and other important organs. It may even cause septicemia, but this usually happens to children with weakened immunity as a result of chronic diseases. 

The most infections with staphylococcus aureus or pseudomonas are visible on the skin. These bacteria may cause different types of diseases from boils, acne, folliculitis (inflammation of hair roots) to scalded inguinal or armpit skin and impetigo (fluid- filled blisters, golden-like, which occur especially around the mouth and nose). 

If they get into the digestive tract, the two bacteria lead to a type of food borne illness which manifests through abdominal cramps, vomiting, diarrhea and it occurs suddenly, after 1-6 hours from contamination and disappears same suddenly in one or two days. If this illness doesn't leave marks on the healthy adults, children might have bigger problems especially if they are too little, meaning that the staphylococcus might last and resist to the treatment. Pseudomonas aeruginosa might lead to epidemic diarrhea in nurseries and kindergartens. 

The staphylococci may target the joints too (knees, hips, elbows, etc.) leading to septic arthritis, a painful diseases which causes swelling of the joints and fever. If one of the staphylococci gets into the blood, it might reach he organs, including the heart and lungs. Therefore, these bacteria are responsible for pneumonia, pharyngitis, bronchitis, meningitis etc. 

As the staphylococcus aureus and the Pseudomonas aeruginosa are found in the skin of many of us, it's possible for a child who developed the infection to have had the bacteria for a long time, and now to have penetrated the body, but it's also possible for the bacteria to come from another person, because the staphylococci are very resistant and may live on towels, pillows and other objects for a long time. In addition, they resist to extreme temperatures (including the cooking) and to salty water. 

The infection is more frequent at children who have been hospitalized recently. Although their complete removal has been attempted for a long time, the two staphylococci are frequent in the hospitals and infect the children with a weakened immunity or with chronic diseases, with burns or surgeries at skin level. The devices with invasive action may also transmit the bacteria. We're talking about the ones used for dialysis, intubation, premature newborns feeding, infusion catheter etc. 

The first step in treating the staphylococcus infections is the determination of the bacteria type. Unfortunately, both the staphylococcus aurous and the Pseudomonas aeruginosa are very resistant to antibiotics. Only 10% of the cases can be treated with penicillin. The rest of them need stronger medication and this still doesn't assure us that the infection will be removed. The infections caught from hospitals are the most difficult to be treated as the staphylococcus if often resistant to methicillin and other mild antibiotics. 

That's why the best treatment of the infection with staphylococcus aureus is the prevention. At hospitalized children this is almost impossible, but there are simple helpful hygiene measures for the rest of cases. The first and most important is the hands washing with water and soap. The second is the proper creasing and care of the injuries and their covering with adhesive and sterile gauze. The third one is good especially for children who spend much time in communities or practice sports: the toilet objects, the towels, clothes, spray must never be shared, no matter who wants to borrow them.
