Detection of Acinetobacter spp. in Blood Cultures by an Improved Fluorescent in Situ Hybridization Assay

Fluorescent in situ hybridization (FISH) allows rapid detection of microorganisms. We aimed (i) to evaluate the sensitivity and specificity of FISH for the detection of Acinetobacter spp. in blood culture specimens and (ii) to test the simultaneous application of two genus-specific probes labeled with the same fluorochrome to increase the fluorescent signal intensity and improve the detection of Acinetobacter spp. Three hundred and twenty blood culture specimens were tested via both the

ACINETOBACTER BAUMANNII – VIRULENCE FACTORS AND EPIDEMIOLOGY OF INFECTIONS

1. Introduction Gram-negative rod Acinetobacter baumannii is an opportunistic pathogen with epidemic potential and contributing to outbreaks of infection worldwide. A. baumannii rods are etiological agents, mainly of lower respiratory tract infections in mechanically ventilated patients, bloodstream infections and wound infections in field hospitals. Increasing drug resistance, hight mortality among patients infected with this pathogen and the difficulty in treating the infections led the World

Low Occurrence of Acinetobacter baumannii in Gulls and Songbirds

Introduction Acinetobacter baumannii is a Gram-negative bacterium, which causes nosocomial infections worldwide. Due to its remarkable capability to develop multidrug resistance, we are running out of treatment options in many parts of the world (Murray et al. 2015). The World Health Organization (WHO), therefore, ranked carbapenem-resistant A. baumannii on the top of a priority list of antibiotic-resistant bacteria for the treatment of which new antibiotics are urgently needed (Tacconelli et

Extensively Drug-resistant Acinetobacter baumannii Belonging to International Clone II from A Pet Cat with Urinary Tract Infection; The First Report from Pakistan

Acinetobacter baumannii is the most prevalent species of genus Acinetobacter that caused various nosocomial infections in clinical settings. A. baumannii is quite ubiquitous and has been found in water, air, and soil. Although the studies related to the animal infections caused by A. baumannii are limited, the reports have highlighted the involvement of Acinetobacter species in respiratory, urinary, bloodstream, and wound infections with an attributable mortality of 47% in pets (Pomba et al

Carbapenem-resistant Acinetobacter baumannii from Air and Patients of Intensive Care Units

To understand the molecular epidemiology and antibiotic resistance of air and clinical isolates of Acinetobacter baumannii, the intensive care unit settings of a hospital in Northern China were surveyed in 2014. Twenty non-duplicate A. baumannii isolates were obtained from patients and five isolates of airborne A. baumannii were obtained from the wards’ corridors. Pulsed field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) were used to analyze the homology relationships of

Histopathological Analysis of Acinetobacter baumannii Lung Infection in a Mouse Model

Introduction Acinetobacter baumannii is an important opportunistic pathogen associated with nosocomial infections, including bacteremia, pneumonia, meningitis, urinary tract infections, and wound infections (Fournier and Rich et al. 2006; Munoz-Price and Weinstein 2008). Recently, multidrug-resistant A. baumannii, the main causative pathogen of nosocomial infections worldwide, has become a significant problem (Kempf and Rolain 2012; Antunes et al. 2014; Ushizawa et al. 2016).

However, further research demonstrated that only 3.4% of strains produced ESBL [49]. In these strains blaSHV12, blaCTX-M-15 and blaTEM-116, encoding respectively SHV-12, CTX-M-15 and TEM-116 β-lactamases [49], were found.

It has also been revealed that depending on the concentration, salicylate induces expression of multi-drug resistance efflux pumps in Escherichia coli, Salmonella enterica subsp. enterica serotype Typhimurium, and Burkholderia cenocepacia. However, salicylate does not affect the expression of the resistance-nodulation-division efflux systems in Stenotrophomonas maltophilia and Acinetobacter baumannii. Most importantly, there were no effects of medicinal products containing some non-antibiotic
