“…The reason for this anomaly is presently unclear, although the lack of protease expression by plesiomonads may be a contributory factor. Two cases of cellulitis of the leg and foot, respectively, have been reported where cultures grew plesiomonads from tissue or exudate material (141,142). On both occasions, other pathogenic bacteria were also isolated, bringing into question what contribution this microbe may have played in the infectious process.…”

SUMMARYAfter many years in the familyVibrionaceae, the genusPlesiomonas, represented by a single species,P. shigelloides, currently resides in the familyEnterobacteriaceae, although its most appropriate phylogenetic position may yet to be determined. Common environmental reservoirs for plesiomonads include freshwater ecosystems and estuaries and inhabitants of these aquatic environs. Long suspected as being an etiologic agent of bacterial gastroenteritis, convincing evidence supporting this conclusion has accumulated over the past 2 decades in the form of a series of foodborne outbreaks solely or partially attributable toP. shigelloides. The prevalence ofP. shigelloidesenteritis varies considerably, with higher rates reported from Southeast Asia and Africa and lower numbers from North America and Europe. Reasons for these differences may include hygiene conditions, dietary habits, regional occupations, or other unknown factors. Other human illnesses caused byP. shigelloidesinclude septicemia and central nervous system disease, eye infections, and a variety of miscellaneous ailments. For years, recognizable virulence factors potentially associated withP. shigelloidespathogenicity were lacking; however, several good candidates now have been reported, including a cytotoxic hemolysin, iron acquisition systems, and lipopolysaccharide. WhileP. shigelloidesis easy to identify biochemically, it is often overlooked in stool samples due to its smaller colony size or relatively low prevalence in gastrointestinal samples. However, one FDA-approved PCR-based culture-independent diagnostic test system to detect multiple enteropathogens (FilmArray) includesP. shigelloideson its panel. Plesiomonads produce β-lactamases but are typically susceptible to many first-line antimicrobial agents, including quinolones and carbapenems.

“…In contrast, the environmental water contamination of wounds described in the literature frequently had more serious outcomes. Infected wounds (Hanson et al 1977), cellulitis (McCracken & Barkely, 1972), gangrene (Quinot et al 1982) and septicaemia have all followed minor injuries such as simple cutaneous abrasions (Wolff, Wiseman & Kitchens, 1980).…”

SUMMARYAn epidemiology analysis of a series of 12 Aeromonas hydrophila infections, including six of septicaemia, which occurred on several wards of one hospital during the summer of 1982 is presented. The hypothesis that the hospital water could be the source of these infections was supported by the isolation of 1-10 motile aeromonads per ml in most of the water samples collected from various points on the hospital water system. Electrophoretic esterase typing was used as an epidemiological screening method to determine the relationship between bacterial strains isolated from the patients and those from water samples. The epidemiology of A. hydrophila infection in the hospital was found to be complex. Amongst the 15 strains of A. hydrophila isolated from patients were 8 zymotypes, while amongst the 126 strains from the water samples there were 37. In some cases, several zymotypes were isolated simultaneously from the same tap water. On one ward, the same zymotype was found in 2 patients and in 2 water samples. The prophylactic measures taken in 1982-5 to avoid oral contamination of immunocompromised patients with infected hospital water have significantly reduced the number of cases of septicaemia. This success has constituted additional retrospective evidence for the water-borne origin of these infections.

“…may be found in patients with diarrhoea (Gracey, Burke & Rockhill, 1982;Motyl & Janda, 1983), and with septicaemia in immunocompromised patients (McCracken & Barkley, 1972). Aeromonas hydrophila and A. sobria are believed to be pathogenic, especially the latter (Wilson et al 1985), but A. caviae is probably not (Millership, Barer & Tabaqchali, 1986).…”

SUMMARYA total of 100 tropical aquaria from six pet shops were sampled for the presence ofSalmonella, CampylobacterandAeromonasspecies. Eight fish tanks contained unusual serotypes of salmonella. None had been used to house terrapins. One hundred and three isolates ofAeromonasspecies were obtained from 98 tanks. One tank containedPlesiomonas shigelloides.NoCampylobacterspecies were isolated. It is suggested that a tropical aquarium may constitute an infection hazard.
