Emerging pathogens in healthcare settings are a concern due to their antibiotic resistant nature. Historically, the water treatment providers have been concerned with Legionella, but the danger has now been extended to include Pseudomonas aeruginosa following numerous outbreaks.
Those in charge of managing healthcare environments have had guidance on the importance of controlling the presence of Legionella via the Health Technical Memorandum HTM 1which provides specific guidance for the control of Legionella in eskkape and cold water systems in healthcare settings. The addendum to HTM 2 was published in March in response to the threat posed by Pseudomonas aeruginosa to immunocompromised patients in augmented care settings. However, there are other emerging pathogens of concern that should be considered by Healthcare and Water Treatment companies—the ESKAPE Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter, Pseudomonas aeruginosa and Enterobacter pathogens.
Staphylococcus aureus is oxidase negative, catalase-positive, and coagulase-positive. Three species of Staphylococci — S. Klebsiella pneumoniae Part of the Enterobacteriaceae family and coliform group of organisms, Klebsiella spp. Pathgoens are four species of Klebsiella: A large polysaccharide capsule distinguishes Klebsiella from other coliform and Enterobacteriaceae family members.
Acinetobacter baumannii Acinetobacter is a genus of Gram-negative bacteria commonly found in soil, water, and sewage environments.
It has the ability to survive on artificial pathogenx and resist desiccation, which allows it to potentially infect new patients. There are many species of Acinetobacter that can cause human diseases 6 with A. It is hypothesized that A. Pseudomonas aeruginosa An aerobic, Gram-negative bacteria that is a member of the Pseudomonadaceae familu. Pseudomonas frequently colonizes manmade environments, such as water systems, where they can form biofilms.
It has been suggested that biofilms provide a breading ground for Legionella bacterial growth. Enterobacter Species A common Gram-negative, anaerobic, non-spore-forming bacteria, Enterobacter is a member of the Enterobacteriaceae family, with several pathogenic strains 6. Three clinically important species from this genus are E.
Enterobacter species are biochemically similar to Klebsiella. However, unlike KlebsiellaEnterobacter is ornithine positive. In nosocomial settings, S.
ESKAPE – Wikipedia
The IDSA report cited the antibiotic resistant nature of ESKAPE pathogens as the main consideration for concern because drug companies are reducing funding into the development of new antibiotics 3. The ESKAPES pathogens are of more prominent concern in healthcare settings due to the high susceptibility of patients elderly, young, and immunocompromised to infections. This means that the sample needs to be sampled, transported to the laboratory, registered, and processed ;athogens that time period.
The guidance for stability times is provided by United Kingdom Accreditation Service UKAS 11 with laboratories able to extend stability times with sufficient validated data. The innovative approach allows microbiologists to provide an instant confirmation of any isolates from culture media and deliver results back to customers along with Colony Forming Unit CFU by volume filtered.
The eskapr generates a mass spectra creating a protein fingerprint unique to each genus and species of bacteria. The faeces of warm blooded animals are a common source of Enterococci bacteria and are an indicator of contamination, with Coliforms and E. Enterococci are more resilient than the primary pathogens to environmental stress and chlorination.
Enterococci tend to outlive their counterparts pathigens of laboratory conditions. This ability to distinguish between the contamination type can therefore potentially identify the source of contamination. Streptococcus bovisStreptococcus equinus, and E.
These organisms are not normally pathobens in human faeces. The presence of intestinal Enterococci provides evidence of recent faecal contamination and detection should lead to consideration of further action, which could include eskapr sampling and investigation of potential sources such as inadequate treatment or breaches in distribution system integrity.
Clinical relevance of the ESKAPE pathogens.
Staphylococci bacteria can colonize in water and soil. Moreover, the bacteria are part of the human flora and paghogens colonize the skin and mucous membranes e.
This eskpae result in a range pathobens ailments including boils, skin sepsis, post-operative wound infections, enteric infections, septicaemia, endocarditis, osteomyelitis, pneumonia, impetigo, meningitis, and arthritis.
The most common pathway for Staphylococcus infection is via skin to skin contact, with inadequate basic hand hygiene from staff, eskaep, and visitors being a frequent root cause in nosocomial settings. Food contaminated with S. The consumption of foods containing S. Although Staphylococci are slightly more resistant to chlorine residuals than E. ALS Environmental can identify over 40 different species of Staphylococcus.
Fourteen of these species are strains of S. Klebsiella colonization can occur in soil, water, or animal faeces. The bacteria are more prominent in waters that are rich in nutrients. In nosocomial scenarios, Klebsiella has been known to pathogejs taps and water distribution systems.
Poor hand hygiene of staff, patients, and visitors has been identified as one of the main sources of colonization of Klebsiella spp. The weakened immune systems of the immunocompromised, both young and old, or those with open wounds are highly susceptible to infection from Klebsiella and colonization may lead to an infection.
On rare occasions, Klebsiella spp. The contamination of drinking water with Klebsiella is not considered as a potential source of gastrointestinal illness. The bacteria are generally present in biofilms and are unlikely to represent a health risk to humans.
The pathogen is usually well controlled with chemical disinfection and entry into distribution systems can be prevented by adequate treatment. Raoultella and Klebsiella are very closely related with some Raoultella being reclassified as Klebsiella in some circumstances by older traditional microbiological confirmation techniques.
The bacteria particularly pathoegns nosocomial settings due to the high use of antibiotics, as outlined in the IDSA and WHO paper and guidance. The pathogen can colonize soil, water, sewage, and the skin of healthy people. This allows the bacteria to be spread by skin contact eeskape person-to-person or from a colonized surface to another person.
Intravenous catheters ppathogens been identified as a source of infection in patients with Acinetobacter. Pathoyens WHO guidance on Drinking Water lists Acinetobacter as a pathogen which transmission through drinking water has been suggested but not yet eskapd evidenced. Acinetobacter infections in immunocompromised individuals can include urinary tract infection, pneumonia, meningitis, and wound infection.
However, an association between the presence of Acinetobacter spp. There is no evidence of gastrointestinal infection through ingestion of Acinetobacter spp. However, transmission of non-gastrointestinal infections by drinking-water may be possible in susceptible individuals, particularly in settings such as healthcare facilities and hospitals. It can multiply in water environments and also on the surface of suitable materials in contact with water. Principal infections include septicaemia, skin, respiratory, urinary tract, and ear and eye.
These infections may occur due to burns, surgery, and open wounds. Cystic fibrosis and immunocompromised patients are prone to colonization with P. The highly susceptible pxthogens patients include those on breathing machines, premature babies, and patients with wounds from surgery or burns. In additional, healthy people can develop mild illnesses with P. Ear infections, especially ptahogens children, and more generalized skin rashes may occur after exposure to inadequately chlorinated hot tubs or swimming pools.
In addition, Enterobacter spp. Most of the infections are seen in low-birth-weight infants i. Risk factors for nosocomial Enterobacter infections include hospitalization of greater than 2 weeks, invasive procedures in the past 72 h, treatment with antibiotics within the past 30 days, and the presence of a central venous catheter.
Specific risk factors for infection with nosocomial multidrug-resistant strains of Enterobacter spp. Enterobacter is present in water, although its presence can be prevented with a successful water treatment programme.
Stenotrophomonas can be found in soils and waters and can colonize drinking water systems. Although there is no natural infection route in humans, S. In severely ill patients, S. The risk of infection can be elevated in healthcare settings and other environments e. The presence of S. The risk of S. Once an immunocompromised patient is infected with S. When analyzing water samples for any pathogenic or bacteriological contamination, time is an important factor. Infection control teams need as much information on any potential edkape factors, pathogenz as waterborne pathogens, as soon as possible.
As our antibiotic use increases, the health risks posed to patients and general population from these pathogens are also likely to payhogens.
With a stringent Water Safety Group, well-maintained maintenance plans, and routine analytical testing and monitoring, we can help keep patients, staff, and the general public safe from Legionella and ESKAPES pathogens.
