“…Table 7 summarizes some retrospective reviews of cumulative data on cases of Plesiomonas sepsis reported in the English literature (29,108,137). Based upon the review of Woo (108) and several published case reports since 2005, there are now over 40 cases of P. shigelloides bacteremia in the literature (111,114,138,139). This is almost double the number reported by Lee (137) …”

“…Slightly under one-third of all bacteremias occur in neonates with meningitis or meningoencephalitis (114). Almost all of these cases of infection occur within the first 5 days of life and appear to have been vertically transmitted (perinatal) rather than transplacental (114). Plesiomonas has only been recovered from maternal feces on three occasions.…”

“…Common predisposing factors leading to sepsis in decreasing order of frequency include blood dyscrasias (thalassemia, sickle cell disease, leukemia), asplenia (functional or anatomic), and iron overload conditions, such as hemochromatosis, biliary tract disease, and cirrhosis (alcoholic, viral) (108,111,112). Slightly under one-third of all bacteremias occur in neonates with meningitis or meningoencephalitis (114).

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.

The reclassification of the order Enterobacteriales to Enterobacterales as well as the taxonomic shuffling of many members of the former family Enterobacteriaceae has increased the importance and awareness of a number of non‐ Enterobacteriaceae families. These include commonly known families, such as Morganellaceae , and lesser–known families, such as Budviciaceae . The family Erwiniaceae contains many important plant‐associated pathogens. Pantoea species have been isolated from plants, humans, and the natural environment, although they are most commonly plant pathogens. While stand‐alone nucleic acid amplification testing is uncommon for detection of Enterobacterales in clinical specimens, syndromic panel testing by nucleic acid amplification has allowed for the rapid progression of clinical microbiology diagnostics. The Morganellaceae are the most familiar organisms for which antimicrobial susceptibility testing is routinely performed. There are several FDA‐cleared panels available for a variety of clinical presentations, including positive blood cultures, pneumonia, and gastrointestinal infections. The GenMark panel includes Morganella morganii and specific identification of Proteus mirabilis .
