I read this news, do you guys read about it? It was stated earlier that she had UTI, but the docs diagnosed it as kidney stones.




RIO DE JANEIRO, Brazil - Health officials say a Brazilian model whose feet and hands were amputated because of an infection has died.

Officials said in a statement early Saturday that 20-year-old Mariana Bridi's condition deteriorated overnight. She died at 2:30 a.m.

The Espirito Santo State Health Secretariat said in the statement she died from complications related to a generalized infection. It was caused by the bacteria Pseudomonas aeruginosa, which is known to be resistant to multiple kinds of antibiotics.

Bridi had been in the hospital in the city of Serra in southeastern Brazil since Jan. 3. She fell ill in December and doctors originally diagnosed her with kidney stones, local media said.

Bridi was twice a finalist in the Brazilian stage of the Miss World pageant.

My grandson went to the doctor for a pin hole sore surrounded by red on his arm, the doc said it was a bug bite and sent him home. The next morning he went back because it was getting bigger fast and the doc gave him some antibiotic cream and sent him home. The next morning his arm was swollen to the size of his leg and turning blue so he went back and they found that it was MRSA so they put him on antibiotics and proceeded to remove a large marble size chunk of his arm leaving a nice sized hole. The doctor who treated him in the emergency room said if had waited just a few hours longer he would have lost the arm. He is young and healing fast but he will miss his chance to wrestle in district championships and won't get to go to state championships this year.

Does anyone knows how to prevent contracting such a bacteria Pseudomonas aeruginosa?

It lives everywhere on earth, including on our skin but only attacks compromised (damaged or weak) tissue so there's no real way to avoid it. I had it in my bladder and kidneys about six months ago, ended up I was pretty well peeing straight pus at one stage and it started spreading to my lungs. There was just one drug which would touch it other than having to be admitted (or was that committed) to hospital. Good old Noroxin, whoever discovered that should get a medal. I also had it majorly after my injury as a lot of dirt and scum was pushed deep into my body. Mostly our bodies if healthy will fight it off before it becomes established. Unfortunately we aren't all healthy but I wouldn't worry about it too much, there are hundreds of thousands of bugs out there we can catch as well.

Like other members of the genus, Pseudomonas aeruginosa is a free-living bacterium, commonly found in soil and water. However, it occurs regularly on the surfaces of plants and occasionally on the surfaces of animals. Members of the genus are well known to plant microbiologists because they are one of the few groups of bacteria that are true pathogens of plants. In fact, Pseudomonas aeruginosa is occasionally a pathogen of plants. However, Pseudomonas aeruginosa has become increasingly recognized as an emerging opportunistic pathogen of clinical relevance. Several different epidemiological studies track its occurrence as a nosocomial pathogen and indicate that antibiotic resistance is increasing in clinical isolates.

Pseudomonas aeruginosa is an opportunistic pathogen, meaning that it exploits some break in the host defenses to initiate an infection. In fact, Pseudomonas aeruginosa is the epitome of an opportunistic pathogen of humans. The bacterium almost never infects uncompromised tissues, yet there is hardly any tissue that it cannot infect if the tissue defenses are compromised in some manner. It causes urinary tract infections, respiratory system infections, dermatitis, soft tissue infections, bacteremia, bone and joint infections, gastrointestinal infections and a variety of systemic infections, particularly in patients with severe burns and in cancer and AIDS patients who are immunosuppressed. Pseudomonas aeruginosa infection is a serious problem in patients hospitalized with cancer, cystic fibrosis, and burns. The case fatality rate in these patients is near 50 percent.

Skin Samples Rife With Unknown Bacteria
by Kate Melville

Scientists from the NYU School of Medicine say that the skin, the largest organ in our body, is a kind of zoo of bacterial inhabitants, with nearly ten percent being previously unknown species. Surprisingly, the NYU study, published in the Proceedings of the National Academy of Sciences, is the first to identify the composition of bacterial populations on the skin using a method that involved extracting 16S ribosomal DNA from the samples. "This is essentially the first molecular study of the skin," says NYU's Dr. Martin J. Blaser. The skin has been, he adds, effectively terra incognita, until now.

The three year study, part of an emerging effort to study human microbial ecology, found that some of the bacteria on the skin appear to be more or less permanent residents while others are transient. "Many of the bacteria of the human body are still unknown," says Dr. Blaser. "Ultimately what we want to do is compare disease and health. Keeping the bacterial populations in our body stable may be part of staying healthy."

For their bacterial audit, the researchers took swabs from the inner right and left forearms of six individuals picking the region halfway between the wrist and the elbow for its convenience. Because they also wanted to study change over time, they took swabs from four of the individuals 8 to10 months after the first test. Roughly half (54 percent) of the bacteria identified in the samples represented the genera Propionibacteria, Corynebacteria, Staphylococcus and Streptococcus, which have long been considered more or less permanent residents in human skin. The researchers found evidence for 182 species of bacteria in the skin samples and eight percent were unknown species that had never before been described.

The subjects differed markedly in the overall composition of the bacterial populations on their skin. They only had four species of bacteria in common: Propionibacterium acnes, Corynebacterium tuberculostearicum, Streptococcus mitis, and Finegoldia AB109769. "This is a surprise," said co-researcher Dr. Zhan Gao. "But many things affecting the skin affect bacteria, such as the weather, exposure to light, and cosmetics use." Almost three-quarters of the total number of bacterial species were unique to individual subjects, suggesting that the skin surface is highly diversified in terms of the bacteria it harbors. Three bacterial species were only found in the male subjects: Propionibacterium granulosum, Corynebacterium singulare, and Corynebacterium appendixes. While the sample is too small to draw conclusions, the scientists believe that women and men may harbor some different bacterial species on their skin. In each individual, the bacterial populations varied over time while revealing a core set of bacteria for each individual.

The team used a powerful molecular method that involved extracting a subunit of genetic material called 16S ribosomal DNA from the samples. "It is kind of a common currency, it's a conserved gene," explained Dr. Blaser. The researchers then bred colonies of each single species of bacteria present in the skin samples. Then they picked out the species-specific genetic regions in the bacteria. After sequencing those regions, the researchers consulted 16S rDNA databases to determine the bacterial species present in each sample. Many bacteria in the database only exist as sequences and have nether been named or extensively studied. Those are termed SLOTUs, or species-level taxonomic units. All up, the team found a total of 182 species - or SLOTUs - and 91 genera of bacteria in the skin samples.

Next up, the research team wants to look at diseased skin. "We plan to ask the question: Are the microbes in diseased skin, in certain diseases like psoriasis or eczema, different than the microbes in normal skin?" said Dr. Blaser.

Is it that sci people are immunocompromised and more likely to catch the bacteria than most other people?
