Essay On Pseudomonas Aeruginosa

Great Essays
Pseudomonas Aeruginosa also known as P. aeruginosa is a potential and commonly lethal cause of gram-negative infections (McCarthy, 2015). Infections resulting from P. aeruginosa are related with high rate of mortality and morbidity (Mizuta et al., 2006). Regrettably, the rise in P. aeruginosa resistance increasingly complicates decisions concerning treatment and leads to possible delays in suitable empirical dual antimicrobial therapy (Mizuta et al., 2006). However, early empirical dual antimicrobial therapy is one possible option that can be used that can lead to one selected agent that can be active against a pathogen that is causing infection (Tamma, Cosgrove & Maragakis, 2012). Dual antimicrobial therapy is normally utilized when infection …show more content…
aeruginosa is normally susceptible. Nevertheless, it is not clear if this is the optimal way to select two antimicrobials for combined or dual therapy. For instance, in the case isolates resistant to one drug are also resistant to another drug, combining these two drugs certainly does not attain coverage increase. However, to come up with a suitable combination of antimicrobial agents for P. aeruginosa empirical therapy infection, an evaluation needs to be done. This will ensure that the optimum antibiogram to consult for dual therapy will have adequate information with respect to which dual therapy accomplishes the greatest P. aeruginosa coverage.
Objectives
The objective of this study is to identify an antimicrobial regime that optimizes the chance of achieving an effective regimen against P. aeruginosa isolates of blood through the development of a dual antibiogram (Christoff et al., 2010). Other objectives examine the identification of risk factors for drugs that are multi-resistant P. aeruginosa, and find out the effect on mortality when attaining one, or two active agents in all neutropenic patients.

aeruginosa, limitation exist that may undermine the development of a suitable combination antibiogram for P. aeruginosa infections. Although targeting was done on a variety of pathogens that are gram negative when choosing empirical therapy, analysis is only limited to isolates of P. aeruginosa (Mizuta et al., 2006). Antibiograms in the study were created based on the results of positive respiratory cultures (Pogue et al, 2011). This method only identified the organisms that were seen to require coverage in an empirical regime. Data on possible patient specific state, such as severity of illness, comorbidities, and prior antibiotics were not included. Hence, it becomes impossible to measure the potential impact of exposure of healthcare in this analysis. These limitations highlight the issue that analysis should not only be limited to isolated P. aeruginosa infections, in addition to creating antibiograms that are based on both positive and negative respiratory cultures. Also, data needs to be readily available to allow clinicians to measure the potential impact of exposure of healthcare in this

    They also mention that these trials excluded patients who have resistant strains and other comorbidies. But their recommendation is to use 2 different antipseudomonal agents from different classes, if more than 10% of the bacterial isolates are resistant to the antipseudomonal antibiotic which was chosen originally. This double coverage is recommended in patients with structural lung disease or if the prevalence of antibiotic resistance is unknown. Aminoglycosides and colistin is not recommended but could be used IV or via inhalation if the isolate susceptible to only those agents. Once the pseudomonas isolate is known they recommend appropriate…

    For instance penicillin is known to be effective against gram positive bacteria including Staphylococcus aureus of which during its activity forms surface protein that binds and leads to the osmotic lysis (Willey et al, 2011 page832). However, there are some emergences of bacteria resistance to penicillin causing pathogenic Staphylococcus aureus infections know as Methicillin – resistant Staphylococcus aureus (MRSA) (Chaitow, 1998) commonly found in hospitals. The results showed that Ciprofloxacin (C) was effective against S. aureus solid proof backing the literature that the drug has capabilities against gram-negative species better than Gram –positive (Heritage et al, 1999).…

    All of the isolates shown in Table 1 were resistance to S. aureus and were considered antibiotic producers. However, only isolate 12 and 16 showed resistant to the unknown Gram-negative organism. All of the antibiotic producers were then tested against Enterococcus faecalis, Pseudomonas putida, Acinetobacter baylyi, Escherichia coli, and Enterobacter aerogenes by the streak-plate method, which can be seen in Table 2. As demonstrated in Table 2, none of the antibiotic producers were found to be resistant against Enterococcus faecalis or Pseudomonas putida. Table 2 also showed isolates 3 and 4 were resistant to Acinetobacter baylyi, isolate 12 was resistant to Escherichia coli, and isolates 12 and 16 were resistant to Enterobacter aerogenes.…

    aeruginosa is a serious threat to immune-compromised patients. It accounts for 35-40% of urinary tract infections in the hospital (Black 2012). In respiratory infections, such as pneumonia it causes hemorrhages and damages the respiratory airways that can be fatal as it causes an inflammatory response (Descamps et al. 2012). This pathogen is known to be the leading cause of respiratory infection in the world (Descamps et al. 2012), which can be ventilator-associated or hospital-acquired pneumonia. In chronic pneumonia, such as in cystic fibrosis, P. aeruginosa is the most frequent cause of mortality (Descamps et al. 2012).…

    Being an inhabitant of all environments, from aquatic to terrestrial, from soil to distilled water, from plants to humans, P. aeruginosa is the quintessence of microbial arms depot. It produces a wide range of secondary metabolites to protect its niche from other fungi and distantly related bacteria. In order to fight fellow Pseudomonads and other closely related bacterial species that may compete for common niches, all strains of P. aeruginosa also produce a broad range of bacteriocins referred to as pyocins. The two major groups of pyocins produced by P. aeruginosa are (i) S-type pyocins (colicin-like bacteriocins), (ii) Tailocins (high-molecular weight bacteriocins that resemble phage tails). S-type pyocins are colicin-like bacteriocins produced by P. aeruginosa.…

    E. faecalis is a gram positive bacterium, which is among the most antibiotic resistant bacteria. Containing many natural antibiotic resistances, it has acquired immunities transferred in r-plasmids among unrestrained bacteria. Since over a quarter of its genome is exogenously attained, this leads to its resistance to the strongest antibiotics or sometimes all antibiotics. This is a large concern in hospital environments and with people with low immune systems since they are more susceptible to infection.…

Select comorbidities were associated with MRSA colonization (congestive heart failure, diabetes, pulmonary disease, immunosuppression, and renal failure; P < .01 for all), while others were not (human immunodeficiency virus, cirrhosis, and malignancy). ICU admission was not associated with an increased risk of MRSA colonization (OR, 1.1 [95% CI, 0.6–1.8]; P = .87) (McKinnell et al., 2014, p.…

    Sepsis syndrome (SS) is a clinical syndrome that develops when an infection triggers a dysregulated inflammatory host response, resulting in life-threatening organ dysfunction (1). It exists on a continuum of severity, ranging from early infection and bacteraemia to severe sepsis and septic shock (1). Sepsis can ultimately result in multiple organ failure and death, and is a major cause of morbidity and mortality globally. Sepsis has a high mortality rate.…

    Healthcare-associated infections (HAI) cause an estimated 1.7 million infections and 99,000 deaths annually in the United States costing us approximately $17-29 billion a year (Center for Disease Control, n.d). HAIs can lead to increased hospitals stays, increased use of diagnostic tests, treatment and antibiotics. The Joint Commission added the reduction of Central Line Associated Blood Stream Infections (CLABSI), reduction of Surgical Site Infections (SSI) and the reduction, incidence and transmission of Multi-drug Resistant Organisms (MDRO) as new HAI national patient safety goals in 2009 (Saufl, 2009). According to Broaders and Srikanth (2014) most HAIs are caused by MDROs, making up two-thirds of reported HAIs.…
