Ventilator-associated pneumonia with Col-S strains: a successful comeback of colistin! BJID
Mukhopadhyay,C.; Krishna,S.; Vandana,K.E.; Shenoy,A.; Bairy,I..
Emergence of multi and pan-drug resistant Gram-negative bacteria causing nosocomial infections in intensive care settings has become a challenge for clinicians. The mortality rate of ventilator-associated pneumonia (VAP) is known to increase when the initial microbiological diagnosis and antimicrobial therapy are inappropriate. We present a case of a 18-year-old man, who after being admitted following an accident, had developed VAP due to multi-drug resistant Pseudomonas aeruginosa and Acinetobacter spp. and had a downhill clinical course despite broad-spectrum antibiotic treatment. The strains were found to be Col-S, as the susceptibility was tested. Colistin was instituted, with remarkable recovery. It is imperative to diagnose VAP with multi-drug...

Effect of sub-minimum inhibitory concentrations of ciprofloxacin, amikacin and colistin on biofilm formation and virulence factors of Escherichia coli planktonic and biofilm forms isolated from human urine BJM
Wojnicz,Dorota; Tichaczek-Goska,Dorota.
The aim of this study was to determine the effect of subinhibitory concentrations (sub-MICs) of ciprofloxacin, amikacin and colistin on biofilm formation, motility, curli fimbriae formation by planktonic and biofilm cells of E. coli strains isolated from the urine of patients with various urinary system infections. Quantification of biofilm formation was carried out using a microtiter plate assay and a spectrophotometric method. Bacterial enumeration was used to assess the viability of bacteria in the biofilm. Curli expression was determined by using YESCA agar supplemented with congo red. Using motility agar the ability to move was examined. All the antibiotics used at sub-MICs reduced biofilm formation in vitro, decreased the survival of bacteria, but...

Antimicrobial resistance in Enterobacteriaceae in Brazil: focus on β-lactams and polymyxins BJM
Sampaio,Jorge Luiz Mello; Gales,Ana Cristina.
ABSTRACT During the last 30 years there has been a dissemination of plasmid-mediated β-lactamases in Enterobacteriaceae in Brazil. Extended spectrum β-lactamases (ESBL) are widely disseminated in the hospital setting and are detected in a lower frequency in the community setting. Cefotaximases are the most frequently detected ESBL type and Klebsiella pneumoniae is the predominant species among ESBL producers. Klebsiella pneumoniae carbapenemase-producing Enterobacteriaceae became widely disseminated in Brazil during the last decade and KPC production is currently the most frequent resistance mechanism (96.2%) in carbapenem resistant K. pneumoniae. To date KPC-2 is the only variant reported in Brazil. Polymyxin B resistance in KPC-2-producing K. pneumoniae...

Membrane permeabilization of colistin toward pan-drug resistant Gram-negative isolates BJM
Mohamed,Yasmine Fathy; Abou-Shleib,Hamida Moustafa; Khalil,Amal Mohamed; El-Guink,Nadia Mohamed; El-Nakeeb,Moustafa Ahmed.
Abstract Pan-drug resistant Gram-negative bacteria, being resistant to most available antibiotics, represent a huge threat to the medical community. Colistin is considered the last therapeutic option for patients in hospital settings. Thus, we were concerned in this study to demonstrate the membrane permeabilizing activity of colistin focusing on investigating its efficiency toward those pan-drug resistant isolates which represent a critical situation. We determined the killing dynamics of colistin against pan-drug resistant isolates. The permeability alteration was confirmed by different techniques as: leakage, electron microscopy and construction of an artificial membrane model; liposomes. Moreover, selectivity of colistin against microbial cells was...
