Anaerobic Infections The blog explains the microbiology, diagnosis, and treatment of infections caused by anaerobic bacteria. It was was created by Itzhak Brook MD. Infections caused by anaerobic bacteria are common, and may be serious and life-threatening. Anaerobes predominant in the bacterial flora of normal human skin and mucous membranes, and are a common cause of bacterial infections of endogenous origin.

Gram staining staphylococcus aureus and pseudomonas

An antibiotic, no longer used, that was developed to treat beta-lactamase-producing strains of S. It is determined in the laboratory and used together with breakpoints to decide whether the bacterial isolate is susceptible or resistant to that antibiotic.

What are we trying to accomplish? How will we know that change is an improvement? What changes can we make that will result in an improvement? Molecular epidemiology The laboratory characterisation of bacteria and the genetic elements responsible for any resistance to antibiotics.

Can be used to investigate transmission of bacteria or resistance in healthcare settings Morbidity The state of being ill, diseased or injured.

Mortality Death, or the frequency or number of deaths. Mutant An organism with a different genetic character due to a change in its DNA.

Mutation A change in the genetic code of an organism. Mycobacteria tuberculosis The bacterium that causes tuberculosis. Nosocomial infection An infection acquired in hospital. Occupied bed-days OBDs Total number of bed-days of all admitted patients accommodated during the reporting period, taken from a count of the number of inpatients at about midnight each day.

Details for patients being admitted and leaving on the same day are also recorded as OBDs, counting one OBD for each same-day patient. Outbreak A classification used in epidemiology to describe a small, localised group of people infected with a disease.

Outpatient A patient who visits a healthcare facility for diagnosis or treatment without spending the night. Sometimes called a day patient, day-stay patient or day-only patient. Parenteral Getting a drug or substance into the body by injection.

Pathogen A disease-causing agent. The term is often used to refer to infectious microorganisms, such as bacteria, viruses or fungi. It stands for Polymerase-chain reaction.

It is a technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.

Petri dish Shallow cylindrical glass or plastic lidded dish that microbiologists use to culture microorganisms. Pharmacodynamics PD Is the study of the biochemical and physiological effects of drugs on the body or on microorganisms or parasites within or on the body and the mechanisms of drug action.

Multiple, small tests of change are reported as PDSA cycles. Plasmids Circular pieces of DNA, highly variable in size and properties, which may carry the genetic instructions to make bacteria resistant to antibiotics.

Plasmids may be transferred between bacteria, so aiding the spread of resistance. Procalcitonin A precursor of the hormone calcitonin has been proposed as a biomarker for bacterial infections Prophylactic Medications or treatments that are preventive in the treatment of disease.

For example, antimicrobials are sometimes given prophylactically before surgery to prevent infection. Prophylaxis Treatment given or action taken to prevent infection.

Quality improvement A formal approach to the analysis of performance and systematic efforts to improve it. Quinolones A family of antibiotics with a broad-spectrum of activity.Learn about BD Life Sciences – Diagnostic Systems package inserts.

Oct 17,  · Necrotizing fasciitis is a rapidly progressive inflammatory infection of the fascia, with secondary necrosis of the subcutaneous tissues.

The speed of spread is directly proportional to the thickness of the subcutaneous layer. Oct 08,  · NHAP is generally included in the category of HCAP because of the high incidence of infection with gram-negative bacilli and Staphylococcus arteensevilla.comr, some authors accept NHAP as a separate entity because of distinct epidemiologic associations with infection in nonhospital healthcare settings.

[] Pneumonia in patients in nursing homes and long-term care facilities has been . Organism. Comments. Coagulase-negative Staphylococci Most common pathogen in CR-BSI.

Staphylococcus aureus. Increasing prevalence of MRSA strains Gram-negative bacilli. Among the resistant gram negative bacilli,Acinetobacter baumannii predominates in Europe.

In USA Pseudomonas aeruginosa seems to be more prevalent Enterococcus spp.. E. faecalis is more common than e.

Gram positive bacteria - Staphylococcus aureus

faecium. Pathogenesis in humans. Both gram-positive and gram-negative bacteria can be pathogenic (see list of pathogenic bacteria).Six gram-positive genera of bacteria are known to cause disease in humans: Streptococcus, Staphylococcus, Corynebacterium, Listeria, Bacillus and Clostridium.

Another 3 cause diseases in plants: Rathybacter, Leifsonia, and Clavibacter. Klebsiella pneumoniae is a Gram-negative bacterium that is frequently found in the flora of the mouth, skin and intestines as well as in natural environments.K. pneumoniae is an opportunistic pathogen that can cause severe hospital-acquired infections such as septicaemia, pneumonia, urinary tract infection and soft tissue infection in debilitated individuals.
