Disease manifestations are a combination of the site (or sites) of infection, bacterial factors, and the host response to the following factors: In an optimal situation, from the host’s point of view, entry of Enterobacteriaceae into an organ or site of infection results in an appropriate host response of sufficient magnitude to clear the inciting pathogen and is then down-regulated resulting in minimal collateral host damage. 328(1):21-8. [Medline]. In severe cases, the infection may move to the kidneys. Enterobacter cloacae infections, especially those of the the bloodstream can lead to low blood pressure and shock. [Medline]. School's Open and Kids Are Getting Sick: Should Our Approach Change? Serratia and Enterobacter infection may rarely be acquired through a variety of infusates, including medications and blood products. June 2017; Accessed: June 7, 2019. [Medline].
Extra-intestinal pathogenic E. coli (ExPEC) infections, A. Outpatient oral therapy of uncomplicated cystitis, TMP-sulfa (DS tab BID x 3 d) if resistance is less than 20%, amoxicillin/clavulanate (amox/clav) x 3-7d. Transmission usually leads to colonization prior to infection, which may or may not develop. Occasionally, strains of E. coli, K. pneumoniae, and other Enterobacteriaceae possess plasmids expressing AmpC beta lactamases. Carbapenemase prevalence is low, but NDM-1-containing isolates are described. [Medline]. Siegel JD, Rhinehart E, Jackson M, Chiarello L and the HICPAC.
231-42. It can cause a number of problems, including skin, respiratory, and urinary infections; septic arthritis, and inflammation of the heart valves. What common complications are associated with infection with this pathogen. Enterobacter cloacae can be acquired through the skin, urinary tract, or gastrointestinal tract. Reinert RR, Low DE, Rossi F, et al. Antibiotic Essentials. A. Commensal E. coli usually require an aggravating factor, a compromised host defense, or large challenge inoculum to cause infection; for example: UTI in the presence of a urinary catheter, peritonitis after fecal contamination due to bowel disruption, cholangitis with biliary tract obstruction. [Medline]. October 4-8, 2017. Comparative activities of doripenem versus isolates, mutants, and transconjugants of Enterobacteriaceae and Acinetobacter spp. [Medline]. 2005 Jul. 51(1):21-6. Drugs. 2008 Mar 15. 2017 Feb. 67 (2):502-504. It is a professional pathogen that can readily infect a normal host. Preventive measures in particular are key to avoiding... read more, Impaired immune defences, invasive procedures and low compliance to infection prevention measures favour the transmission of pathogens in... read more. Enterobacter cloacae is a member of the normal gut flora of many humans and is not usually a primary pathogen. Foster DR, Rhoney DH. A new Phenotypic Test for the Detection of Carbapenemases - The Modified Carbapenem Inactivation Method (mCIM). C. fruendii and C. koseri are responsible for the majority of Citrobacter infections, which occur primarily in LTCFs and hospitals (1-2% of hospital-acquired infections). Jiang X, Ni Y, Jiang Y, et al. Prevalence is increasing worldwide, particularly CTX-M types. However, if the host is immunologically naive, in the absence of antimicrobial treatment, outcome is often decided by the effectiveness of initial innate response. ), (A review of antimicrobial resistance in the Enterobacteriaceae. Prior antimicrobial use, recent or ongoing hospital care, and international travel, especially to the Middle East or Asia, increase the likelihood of MDR-strains. Risk factors for emergence of resistance to broad-spectrum cephalosporins among Enterobacter spp. These often present on large, transferrable plasmids with linked or associated resistance to FQ, TMP-sulfa, aminoglycosides, and tetracyclines. 2002 May. [Medline]. https://clsi.org/media/1802/ast_newsletter_final_2017.pdf, http://www.cdc.gov/ncidod/dhqp/pdf/guidelines/Isolation2007.pdf, http://www.cdc.gov/ncidod/dhqp/pdf/ar/mdroGuideline2006.pdf, Association of Medical Microbiology and Infectious Disease Canada, Southern Society for Clinical Investigation, American Society of Tropical Medicine and Hygiene. Community acquired infections, often associated with abscesses, have been primarily described up to now, but our understanding of the infectious spectrum of this pathogen is evolving, in part due to the lack of an optimal test for the clinical microbiology to differentiate cKP from hvKP. 2005 Dec 12-26. Antimicrobial stewardship programs should be implemented to minimize the development of antimicrobial resistance. Proteus UTI can be complicated by infection stones, and stone removal is requisite for cure. [Medline]. Pain may appear to spread to nearby areas.
Do not use amp, first- and second-generation cephalosporins. nitrofurantoin (but should not be used if pyelonephritis is a concern), TMP-sulfa or FQ if local susceptibilities are known and greater than 80%. [Medline]. The goal of therapy is to eradicate the infection and to prevent complications 2. 52(3):181-6. These strains appear genetically distinct from classic K. pneumoniae, but the lack of an unequivocal genotypic/phenotypic marker(s) has precluded a comprehensive understanding of the prevalence and spectrum of disease; although a hypermucoviscous phenotype (+ string test) has been used as a surrogate. (A report on a gene that confers resistance to fosfomycin. Species of the Enterobacter cloacae complex are widely encountered in nature, but they can act as pathogens. Activity of ertapenem (MK-0826) versus Enterobacteriaceae with potent beta-lactamases. 60 (6):3840-4. Salmonella, Shigella, and Yersinia are not discussed here. Sader HS, Jones RN, Dowzicky MJ, et al. [Medline]. Klebsiella causes extra-intestinal infection, but a hemorrhagic colitis has been associated with Klebsiella oxytoca. Durand ML, Calderwood SB, Weber DJ, et al.
The biochemical and molecular studies on E. cloacae have shown genomic heterogeneity, comprising six species: Enterobacter cloacae, Enterobacter asburiae, Enterobacter hormaechei, Enterobacter kobei, Enterobacter ludwigii and Enterobacter nimipressuralis, E. cloacae and E. …
), (A report on food animals as a source of MDR-E. J Infect Dis. Do not use amp, amp-sulbactam, and the first- and second-generation cephalosporins. ), (A case report describing successful treatment of XDR K. Antimicrobial susceptibility among Acinetobacter calcoaceticus-baumannii complex and Enterobacteriaceae collected as part of the Tigecycline Evaluation and Surveillance Trial. Maria D Mileno, MD is a member of the following medical societies: Alpha Omega Alpha, American College of Physicians, American Society of Tropical Medicine and Hygiene, Infectious Diseases Society of America, International Society of Travel Medicine, Sigma XiDisclosure: Nothing to disclose. J Infect. Rare settings after the neonatal period include disruption of the meninges due to trauma or neurosurgery or in the presence of cirrhosis. Prior antimicrobial therapy may inhibit or slow growth. LTCF are an important reservoir for resistant strains. Alhambra A, Cuadros JA, Cacho J, et al. Although resistance to tigecycline remains uncommon, Serratia has a narrow susceptibility window and decreased permeability or efflux may confer resistance. Once-daily tigecycline therapy of multidrug-resistant and non-multidrug-resistant gram-negative bacteremias. Ceftaz-avi & ceftolozane/tazo are active in vitro, but clinical data are limited. Feb 14 2013. 139 medications found for enterobacter cloacae urinary tract infection. Although the majority of E. coli strains are still relatively antimicrobial friendly in the United States, particularly in young, antibiotic naive, healthy individuals isolates are increasingly resistant (e.g., 17.1% FQ resistance in US outpatient isolates in 2010). 62 (9):165-70. Pharmacokinetic considerations regarding tigecycline for multidrug-resistant (MDR) Klebsiella pneumoniae or MDR Acinetobacter baumannii urosepsis. Enterobacteriaceae can grow aerobically and anaerobically. 55(1):49-57. [Full Text].
“Classic” K. pneumoniae: Most infections occur in hospital or LTCF.
Recently, we have countered by our ability to develop “tools” (e.g., antimicrobials). Do not use amp, amp/sulbactam, first-generation cephalosporins, tigecycline, tetracyclines, nitrofurantoin, fosfomycin, and polymyxins. ), (A presentation of NHSN data from 2006-7. Prophylaxis should not routinely be used to prevent infection because of the Enterobacteriaceae, except for select patient groups (e.g., FQ prophylaxis) should be considered for high risk patients (anticipated absolute neutrophil count less than100 cell/mm3 for more than 7 days) undergoing chemotherapy. [Medline]. ), (The report on K. oxytoca as a cause of hemorrhagic colitis.
