“…Voss et al found that 13 of 28 Aeromonas wound and soft tissue infections during a 4-year period from 1985 to 1989 were associated with a water-related injury, and 43 % of the total could be directly related to water from a lake or river [7]. In Okinawa, 38 cases of extraintestinal Aeromonas infections were reported in a 5-year period from April 2008 to March 2013 in Urasoe General Hospital in Urasoe city (population about 114,000) adjacent to the prefectural capital Naha city [31].…”

Objectives The genus Aeromonas is known to causes diseases such as food poisoning, sepsis, and wound infection. However, the mode of Aeromonas transmission from environment to humans is not clearly understood. To evaluate the health risks of Aeromonas spp. in environmental freshwater, the number, proportion and putative virulence factors of Aeromonas species were investigated in Okinawa Prefecture, Japan. Methods Environmental freshwater samples were collected from three dams, two springs and three private wells. Aeromonas strains were identified by the biochemical method and the viable count was calculated. The production of extracellular enzymes and the virulence genes were investigated for possessing putative virulence factors using representative isolates. Results At least seven species of already-known Aeromonas isolates as well as unidentified Aeromonas spp. with/without arginin dehydrolase (ADH) exist in water at these sites. Aeromonas spp. was found to exist at over 1000 CFU/100 ml in one spring and two wells. A. veronii biovar sobria and A. jandaei were the predominant species in dams, and A. hydrophila and/or A. eucrenophila were predominant in wells. Almost all the sampled Aeromonas species produced protease, gelatinase, lipase, esterase and DNase, but A. caviae, A. caviae-like bacteria, and A. eucrenophila had low hemolytic activity. Most sampled A. hydrophila strains possessed both aerolysin gene (aer) and hemolysin gene (hlyA), but A. caviae and A. eucrenophila strains did not possess either gene. Conclusions Since these results indicated that several Aeromonas species having potential pathogenicity exist in environmental water in Okinawa, surveys are recommended as a public health measure.

“…Serious Aeromonas infections can occur in exposed patients with underlying diseases such as hepatitis, diabetes and/or malignant tumors [3,5]. In addition, there have been reports of Aeromonas infections through trauma [6,7] and near-drowning events [8] caused by recreational activities such as boating, fishing and diving.…”

“…In addition to these major pathways, aeromonads can also be acquired by other, less prominent routes. Recreational activities such as boating, fishing, and diving can lead to infection through major or unapparent traumas, as can near-drowning events (23,31,292). As urban sprawl continues to encroach upon rural environments, the potential for Aeromonas infections arising from zoonotic origins will increase.…”

The GenusAeromonas: Taxonomy, Pathogenicity, and Infection

SUMMARY Over the past decade, the genus Aeromonas has undergone a number of significant changes of practical importance to clinical microbiologists and scientists alike. In parallel with the molecular revolution in microbiology, several new species have been identified on a phylogenetic basis, and the genome of the type species, A. hydrophila ATCC 7966, has been sequenced. In addition to established disease associations, Aeromonas has been shown to be a significant cause of infections associated with natural disasters (hurricanes, tsunamis, and earthquakes) and has been linked to emerging or new illnesses, including near-drowning events, prostatitis, and hemolytic-uremic syndrome. Despite these achievements, issues still remain regarding the role that Aeromonas plays in bacterial gastroenteritis, the extent to which species identification should be attempted in the clinical laboratory, and laboratory reporting of test results from contaminated body sites containing aeromonads. This article provides an extensive review of these topics, in addition to others, such as taxonomic issues, microbial pathogenicity, and antimicrobial resistance markers.

“…[61][62][63][64] However, this patient was not immunosuppressed or ill prior to the acute burn injury. 65 The early onset of the bacteremia and the lack of Aeromonas recovered from specimens other than the blood and the IV line tip led us to surmise that river water contaminated the IV line at the time of emergency placement.…”

Trauma occurring in direct contact with freshwater bodies may result in wounds contaminated with a variety of microorganisms. Bacteria belonging to the genus Aeromonas have been recovered from these types of infections. We report two cases of Aeromonas hydrophila infections occurring from freshwater-contaminated wounds. One of these infections was acquired from a river in southeastern New Mexico; the other was from an urban playa lake in West Texas. The latter case prompted an ecological study of the seasonal occurrence of Aeromonas spp. and the incidence of resistance to antimicrobial agents in two of these local lakes. Recent scientific and medical literature data show that Aeromonas should be considered as a possible agent of infection in immunocompetent hosts from water exposure, even if the water is a running river or a seemingly unpolluted ("clean") freshwater lake.
