Acinetobacter

Acinetobacter [asz−in−ée−toe–back−ter] is a group of bacteria commonly found in soil and water. Outbreaks of Acinetobacter infections typically occur in intensive care units and healthcare settings housing very ill patients. While there are many types or “species” of Acinetobacter and all can cause human disease, Acinetobacterbaumannii [asz−in−ée−toe–back−terbō–maa–nee–ie] accounts for about 80% of reported infections. Acinetobacter infections rarely occur outside of healthcare settings.

Common in military settings?

Reservoir: soil and water. Acinetobacter can live on the skin and may survive in the environment for several days. Careful attention to infection control procedures, such as hand hygiene and environmental cleaning, can reduce the risk of transmission.

Portals of entry and exit:

Acinetobactercan be spread to susceptible persons by person-to-person contact or contact with contaminated surfaces. (Direct and indirect via fomites)

Diseases:

Acinetobacter causes a variety of diseases, ranging from pneumonia to serious blood or wound infections, and the symptoms vary depending on the disease. Acinetobacter may also “colonize” or live in a patient without causing infection or symptoms, especially in tracheostomy sites or open wounds.

Symptoms: dependent of diseases caused

How transmitted in healthcare setting:

Acinetobacter poses very little risk to healthy people. However, people who have weakened immune systems, chronic lung disease, or diabetes may be more susceptible to infections with Acinetobacter. Hospitalized patients, especially very ill patients on a ventilator, those with a prolonged hospital stay, those who have open wounds, or any person with invasive devices like urinary catheters are also at greater risk for Acinetobacter infection. Acinetobactercan be spread to susceptible persons by person-to-person contact or contact with contaminated surfaces.

Morbidity/ Mortality: Although Acinetobacter is primarily a colonizer in the hospital environment, it occasionally causes infection. Mortality and morbidity resulting from Abaumannii infection relate to the underlying cardiopulmonary immune status of the host rather than the inherent virulence of the organism.

Mortality and morbidity rates in patients who are very ill with multisystem disease are increased because of their underlying illness rather than the superimposed infection with Acinetobacter.

Additional information: Acinetobacter is often resistant to many commonly prescribed antibiotics.

BurkohlderiaCepacia

Burkholderiacepacia[burk-hōld–er–ee-uh si−pay−shee−uh] is the name for a group or "complex" of bacteria that can be found in soil and water. Burkholderiacepaciabacteria are often resistant to common antibiotics. Burkholderiacepacia poses little medical risk to healthy people; however, it is a known cause of infections in hospitalized patients. People with certain health conditions, like weakened immune systems or chronic lung diseases (particularly cystic fibrosis), may be more susceptible to infections with Burkholderiacepacia. [Burkholderiacepacia is also called B. cepacia Taken from:

  1. Bacteria
  2. Soil and water
  3. Transmission of B. cepacia from contaminated medicines and devices has been reported..B. cepacia can also be spread to susceptible persons by: Person-to-person contact, contact with contaminated surfaces, exposure to B. cepacia in the environment. Also: oral, injection site. (from:
  4. Once B. cepaciaenters the body, there are three possible effects and it is not possible to predict which will happen. Sometimes B. cepaciacolonizes in the lungs, causes no symptoms, and has no long term effect. Other times B. cepacia colonizes in the lungs and causes damaging lung infections and inflammation that lead to a slow deterioration of lung function. In the worst case scenario, B. cepacia can spread throughout the body causing “cepacia syndrome”, which leads to a rapid deterioration of lung function. Cepacia syndrome is a serious condition that does not always respond well to treatment. Unfortunately, even with proper treatment, cepacia syndrome can lead to death within a few weeks.The effects of B. cepacia on people vary widely, ranging from no symptoms at all to serious respiratory infections, especially in patients with cystic fibrosis. (from:
  5. (from:
  6. Transmitted in a healthcare setting by person to person (direct) contact, as well as fomites (contaminated surfaces or equipment)
  7. Morbidity & Mortality: at risk populations include patients with cystic fibrosis, pre-existing lung infections, and immune compromised individuals. “The overall 28-day mortality rate was 41% (11/27). In univariate analysis, underlying diabetes mellitus (p = 0.033), inappropriate initial empirical antimicrobial therapy (p = 0.033), and an elevated Sequential Organ Failure Assessment (SOFA) score (p = 0.002) were significantly associated with mortality. In multivariate analysis, inappropriate initial empirical antimicrobial therapy and an elevated SOFA score were independent risk factors for increased mortality (p = 0.032 and p = 0.028, respectively).” (from:

-Water and soil and infected plants & people (hosts) are reservoirs of this antibiotic-resistant bacteria. Persons with weakened immunity or respiratory conditions are particularly susceptible to respiratory infection from B. cepacia.

-Portal of entry

  • Skin, mouth, injection site

-Portal of exit

  • Contaminated medical devices, sublingual probes, area of dermal contact

-Symptoms

  • The effects of B. cepacia on people vary widely, ranging from no symptoms at all to serious respiratory infections like pneumonia, especially in patients with cystic fibrosis.

-How is the microbe transmitted in a healthcare setting?

  • Person-to-person contact
  • Contact with contaminated surfaces
  • Exposure to B. cepacia in the environment
  • contaminated medicines and devices, including mouthwash and nasal spray.

Mortality: There is a high mortality rate in patients infected with Burkholderiacepacia. Many develop what is known as cepacia syndrome. This is a fatal necrotizing pneumonia that is currently untreatable. (

Interesting Facts:

“An organism that reduces an onion to a macerated pulp, protects other crops from bacterial and fungal disease, devastates the health and social life of cystic fibrosis patients, and not only is resistant to the most famous of antibiotics, penicillin, but can use it as a nutrient!" (J. R. W. Govan, 1998)

C DIFF

Jennifer Honda and Brian Iversen

Clostridium difficile is a spore-forming, Gram-positive anaerobic bacillus that produces two exotoxins: toxin A and toxin B. It is a common cause of antibiotic-associated diarrhea (AAD). It accounts for 15-25% of all episodes of AAD.

What diseases result from Clostridium difficile infection?

pseudomembranous colitis (PMC)

toxicmegacolon

perforations of the colon

sepsis

death (rarely)

What are the main clinical symptoms of Clostridium difficile infection?

Clinical symptoms include:

watery diarrhea

fever

loss of appetite

nausea

abdominal pain/tendernes

How is Clostridium difficile transmitted?

Clostridium difficile is shed in feces. Any surface, device, or material (e.g., commodes, bathing tubs, and electronic rectal thermometers) that becomes contaminated with feces may serve as a reservoir for the Clostridium difficile spores. Clostridium difficile spores are transferred to patients mainly via the hands of healthcare personnel who have touched a contaminated surface or item. Clostridium difficile can live for long periods on surfaces.

Clostridium difficile infection (CDI) often occurs in patients in health-care settings, where antibiotics are prescribed and symptomatic patients, an important source for transmission, are concentrated. From 2000 to 2009, the number of hospitalized patients with any CDI discharge diagnoses more than doubled, from approximately 139,000 to 336,600, and the number with a primary CDI diagnosis more than tripled, from 33,000 to 111,000.

The incidence, mortality, and medical care costs of CDIs have reached historic highs (1,3,9,10). The estimated number of deaths attributed to CDI, based on multiple cause-of-death mortality data, increased from 3,000 deaths per year during 1999–2000 to 14,000 during 2006–2007, with more than 90% of deaths in persons aged ≥65 years (10).

Clostridium Dificile Diana, Adrian, Karina, Suzie

When antibiotics destroy a person's good bowel bacteria, C. difficile bacteria can grow. When this occurs, the C. difficile bacteria produce toxins, which can damage the bowel and cause diarrhea. However, some people can have C. difficile bacteria present in their bowel and not show symptoms.

  1. Clostridium difficile (klos-TRID-e-um dif-uh-SEEL), often called C. difficile or C. diff, is a bacterium that can cause symptoms ranging from diarrhea to life-threatening inflammation of the colon.
  2. Reservoir: The two major reservoirs of C. difficileare colonized or infected persons and contaminated environments. C. difficilespores can survive for weeks to months on environmental surfaces. Any surface, device or material (e.g. commodes, bathing tubs, and electronic rectal thermometers) that becomes contaminated with infectious feces may serve as a reservoir for the C. difficilespores.
  3. The bacteria are found in the feces. People can become infected if they touch items or surfaces that are contaminated with feces and then touch their mouth or mucous membranes
  4. the bacterium that causes an inflammation of the colon; this condition is called colitis
  5. degree to which the environment becomes contaminated with C. difficilespores is proportional to the number of patients with C. difficile-associated diarrhea, although asymptomatic, colonized patients may also serve as a source of contamination.
  6. Transmitted in healthcare setting: Healthcare workers can spread the bacteria to patients or contaminate surfaces through hand contact
  1. Mortality: C. difficile causes diarrhea linked to 14,000 American deaths each year.

Klebsiella

Gram negative Bacteria

Reservoir- Human body

Portal- respiratory system and bloodstream, intestines (fecal-oral)

Disease- pneumonia, blood infections, and meningitis. Liver abscess (UW Medicine)

Symptoms- Pneumonia -high fever, chills, and cough with bloody sputum

Meningitis- nausea, vomiting, altered mental status

Liver abscess- weight loss, anorexia, shortness of breath

This microbe is transmitted in a Healthcare setting the most by ventilators, catheters, and IV ports. If a healthcare worker visits patients without washing hands (direct contact) there is a much higher risk of spreading the disease. It is most common for a person with a lowered immune system to get infected with klebsiella.

Methicillin-resistant Staphylococcus aureus (MRSA)

-Ky Cooper, NaeimehBagheri, SitomHabte

Methicillin-resistant Staphylococcus aureus (MRSA) is a type of staph bacteria that is resistant to certain antibiotics called beta-lactams. These antibiotics include methicillin and other more common antibiotics such as oxacillin, penicillin, and amoxicillin. In the community, most MRSA infections are skin infections. More severe or potentially life-threatening MRSA infections occur most frequently among patients in Healthcare Settings. [Methicillin-resistant Staphylococcus aureus is also called MRSA]

  1. MRSA is a bacteria
  2. Diseases and symptoms

-MRSA can cause skin or wound infections, pneumonia and blood infections. Symptoms of these diseases can include chills fever, swollen rash, infected wounds emitting puss, and coughing shortness of breath.

“This germ does not cause any problems for most people who have it on their skin. But someimes it can cause serious infections such as skin or wound infections, pneumonia, or infections of the blood.”

Often, people first think the area is a spider bite; however, unless a spider is actually seen, the irritation is likely not a spider bite. Most staph skin infections, including MRSA, appear as a bump or infected area on the skin that might be: Red, Swollen, Painful, Warm to the touch, Full of pus or other drainage, Accompanied by a fever

  1. Portal of entery/exit and reservoirs of infection

-MRSA can be passed by direct contact using the skin as a portal of exit and entry. MRSA can also be passed by indirect contact via numerous fomites usually equipment or furniture in hospitals and healthcare settings. The reservoirs of infection for MRSA include the infected person, skin of humans and numerous environmental reservoirs within healthcare settings.

“People who have MRSA germs on their skin or who are infected with

MRSA may be able to spread the germ to other people. MRSA can be

passed on to bed linens, bed rails, bathroom ixtures, and medical equipment. It can spread to other people on contaminated equipment and on the hands of doctors, nurses, other healthcare providers and visitors.”
