“…Our knowledge regarding the extent and diversity of vertebrate species harboring Aeromonas stems from several direct and indirect lines of evidence, namely, (i) systematic surveys of the fecal content of farm and domesticated animals; (ii) surveys of the microbial content of retail foods, including meats, poultry, and dairy products (see "Aeromonas in Foods"); (iii) reports describing human illnesses directly related to bites or other penetrating traumas precipitated by vertebrates such as snakes; and finally, (iv) reports of epizootic infections caused by aeromonads in susceptible species. A Turkish study recently reported that Aeromonas species were identified in the gastrointestinal contents of healthy sheep, cattle, and horses at frequencies ranging from 5% to 10% (32). In the disease state, aeromonads can also cause a variety of serious illnesses in both cold-blooded and warm-blooded animals.…”

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.

Introduction: Aeromonas are food-and water-borne bacteria that are considered to be zoonotic human pathogens. This study aimed to investigate the presence of genes associated with virulence in human and animal Aeromonas isolates and the potential role of animal isolates with regards to human Aeromonas infections. Methodology: The presence of aerA, hlyA, alt, ast, laf, ascF-G, stx1 and stx2 putative virulence genes in 40 human and animal Aeromonas isolates (16 human and 24 animal isolates) were examined by polymerase chain reaction (PCR). DNA fragments of expected sizes were purified and sequenced. BLAST in the NCBI was used to verify any amplified products. Results: PCR screening showed that hlyA, alt, and laf genes were determined at ratios of 6.25%, 50%, and 6.25%, respectively, in human isolates. The ratios of hlyA, alt, ascF-G, laf, stx2, and stx1 genes in animal isolates were 58.3%, 20.83%, 33.3%, 20.83%, 8.33%, and 4.17%, respectively. Neither aerA nor ast genes were detected in any isolates. Any one of eight putative virulence genes was not detected in seven human and eight animal isolates in the study. Conclusions: The current study is the first to investigate the presence of the virulence gene in gull Aeromonas isolates. The manifestation of the presence of the virulence gene and gene combinations was considerable, especially in fish and gull isolates when compared with clinical human isolates. The current study demonstrates the potential importance of fish and gulls in terms of human Aeromonas infections.

SummaryAeromonads infect human through potable water and causes various infections. Their existence in animal are being assessed as potential risk for human health. The aim of this study was to investigate clonal relationship among 52 Aeromonas strains isolated from human with diarrhea (14 strains), healthy food workers (2 strains), animals (24 strains) and drinking water (12 strains) by pulsed-field gel electrophoresis (PFGE). Clonal relation was determined between one diarrheic human isolate and one cattle isolate. No clonal relation was determined between drinking water and human isolates. Two fish isolates, A. caviae and A. sobria, were not distinguished PFGE patterns. Consequently no predominant clone was determined while clonal related strains were determined. Particularly, it is necessary to elicit the epidemiological importance of animals in respect of human Aeromonas infections and extensive studies are required for identification of environmental isolates. Keywords: Aeromonas spp., Human, Animal, Drinking Water, PFGE PFGE ile İnsan, Hayvan ve İçme Sularından İzole Edilen Aeromonas Suşları Arasında Klonal İlişkinin Araştırılması ÖzetAeromonaslar insanlarda çeşitli enfeksiyonlara neden olmakta, içme suları ile insanlara bulaşabilmekte ve hayvanlardaki varlığı, insanlar için potansiyel risk olarak değerlendirilmektedir. Bu çalışmayla pulsed-field gel electrophoresis (PFGE) ile diyareli insanlardan (14 suş), sağlıklı gıda işçilerinden (2 suş), hayvanlardan (24 suş) ve içme sularından (12 suş) izole edilen 52 Aeromonas suşu arasındaki klonal ilişkinin araştırılması amaçlandı. Bir diyareli insan izolatı ve bir sığır izolatı arasında klonal ilişki tespit edildi. İnsan ve su izolatları arasında klonal ilişki tespit edilmedi. İki balık izolatı arasında (A. caviae ve A. sobria) ayırtedilemez PFGE paterni tespit edildi. Sonuç olarak, klonal ilişkili suşlar tespit edilmesine rağmen baskın bir klon tespit edilmedi. Özellikle hayvanların, insan Aeromonas infeksiyonları yönünden epidemiyolojik önemini aydınlatmaya, ayrıca çevresel izolatların identifikasyonuna yönelik kapsamlı çalışmalara ihtiyaç olduğu görüldü.
