“…2,20 All of them were resistant to ampicillin and first-generation cephalosporin, however, aminoglycosides still remains good in vitro activity against these clinical isolates. Additionally, more than 83% of Aeromonas isolates were susceptible to ciprofloxacin, gentamicin, and third-generation cephalosporin.…”

Abstract. Strains of Aeromonas species are prevalent bacteria in coastal areas of southern Taiwan. Aeromonad is known as a cause of epidemic diarrheal disease, and the most common clinical manifestation is acute gastroenteritis. Extra-intestinal infections by Aeromonas species, such as pleural cavity, are rare. Herein, we described the six patients who developed Aeromonas spp.-related empyema, and was successfully treated with antimicrobial agent and drainage.Aeromonas species, a curved Gram-negative rod, causes human infection through exposure to contaminated sea water or ingestion of contaminated seafood.

“…Aeromonas are Gram-negative bacteria that are autochthonous in aquatic environments and are the causative agents of human and fish infections (Figueras et al 2005, Beaz-Hidalgo et al 2010, Janda & Abbott 2010, Parker & Shaw 2011, Figueras & Beaz-Hidalgo 2015. However, in contraposition to the extensive literature implicating Aeromonas in fish diseases, few cases of Aeromonas infections have been reported in marine mammals (Cusick & Bullock 1973, Krovacek et al 1998, Thornton et al 1998, Nielsen et al 2013.…”

Aeromonas dhakensis pneumonia and sepsis in a neonate Risso’s dolphin Grampus griseus from the Mediterranean Sea

A neonate Risso's dolphin Grampus griseus was found stranded alive on a beach in Catalonia, Spain. Rehabilitation attempts were unsuccessful and it died 2 d later, showing pneumonia and sepsis. A pure bacterial culture was obtained from all tissues and blood and identified as Aeromonas hydrophila using the API 20NE. However, sequencing the rpoD gene showed that the strain in fact belongs to A. dhakensis, making this the first report of fatal haemorrhagic-necrotizing pneumonia and sepsis due to this species in a marine mammal. The A. dhakensis strain GMV-704 produced β-haemolysis, possessed several virulence genes and showed sensitivity to several antimicrobials. This study provides a new potential host for A. dhakensis, and its potential virulence in dolphins and its presence in the marine environment may warrant considering this species a potential threat to marine mammals.

“…A eromonas species are Gram-negative environmental bacteria that can cause infections in both immunocompetent and immunocompromised persons (1,2) and have been isolated from a wide range of aquatic environments, including marine ecosystems, freshwater, hospital effluent, and drinking water (1,(3)(4)(5)(6). The global rise of multidrug-resistant bacteria raises concern that a ubiquitous organism, such as an Aeromonas sp., could acquire antibiotic resistance genes derived from human isolates (3,4,7,8).…”

Detection and Whole-Genome Sequencing of Carbapenemase-Producing Aeromonas hydrophila Isolates from Routine Perirectal Surveillance Culture

Perirectal surveillance cultures and a stool culture grew Aeromonas species from three patients over a 6-week period and were without epidemiological links. Detection of the bla KPC-2 gene in one isolate prompted inclusion of non-Enterobacteriaceae in our surveillance culture workup. Whole-genome sequencing confirmed that the isolates were unrelated and provided data for Aeromonas reference genomes.A eromonas species are Gram-negative environmental bacteria that can cause infections in both immunocompetent and immunocompromised persons (1, 2) and have been isolated from a wide range of aquatic environments, including marine ecosystems, freshwater, hospital effluent, and drinking water (1,(3)(4)(5)(6). The global rise of multidrug-resistant bacteria raises concern that a ubiquitous organism, such as an Aeromonas sp., could acquire antibiotic resistance genes derived from human isolates (3,4, 7, 8). A variety of antibiotic resistance phenotypes, including carbapenem resistance (3, 4, 9-15), have been found in both clinical and environmental Aeromonas isolates. Although rare, clinical Aeromonas isolates containing bla KPC genes have been reported (16, 17).Active microbial surveillance for multidrug-resistant Gramnegative organisms is integral to inpatient care at the NIH Clinical Center. Perirectal swabs are collected upon hospital admission, twice weekly in the intensive care unit, and monthly from all inpatients (excluding those in behavioral health wards). Perirectal swabs were inoculated onto HardyCHROM CRE (Hardy Diagnostics, Santa Maria, CA) and incubated at 35°C ambient air for 18 to 24 h. Isolates were identified using matrixassisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), and isolates belonging to Enterobacteriaceae underwent PCR for detection of bla KPC and bla NDM-1 . Stool specimens were plated onto sheep blood, MacConkey, and xylose lysine deoxycholate agars with incubation at 35°C and 5% CO 2 for 48 h, and on Campy CVA agar with incubation at 42°C under microaerophilic conditions. Results from the surveillance cultures that suggest possible nosocomial acquisition of carbapenemase-producing bacteria trigger epidemiological investigations, including environmental sampling.Perirectal surveillance cultures from two hospitalized adult patients and a stool culture from a third patient grew Aeromonas spp. within a 6-week period. The stool culture isolate (from patient A) was resistant to ertapenem and susceptible to imipenem and meropenem; the perirectal isolates (from patients B and C) were resistant to all three carbapenems. MALDI-TOF MS could not reliably identify the isolates to the species level. On average, clinical Aeromonas spp. had been isolated from clinical cultures in only four to five patients per year in our institution since 2010; this was the first time that Aeromonas had been isolated from perirectal surveillance cultures since they were introduced in 2011. This apparent cluster of Aeromonas colonization prompted an investigation. A patient trace (TheraDo...
