Morganella morganii with Proteus and Providencia species comprise the tribe Proteeae and are occasional causes of bloodstream infections (BSIs) (). Morganella morganii has chromosomally encoded bla AmpC, which confers resistance to cephalosporins and penicillins ().As a result, treatment with quinolones, aminoglycosides, co-trimoxazole, or carbapenems is usually recommended (3 – 6).
Background: Morganella morganii is a Gram-negative, rod-shaped, facultative anaerobic bacillus divided into two subspecies, morganii and sibonii. Previously classified as Proteus morganii, it belongs to human gut commensal microbiota. Nevertheless, on rare occasions, especially in nosocomial and postoperative environment as well as in patients with the impaired immune system and young children ...
7 de feb. de 2023 · Morganella only has a single member in its genus M. morganii and two subspecies: M. morganii and M. sibonii, which differ only in trehalose fermentation. Naturally resistant to penicillin, ampicillin, first- and second-generation cephalosporins, fosfomycin, and macrolides. Beta-lactamase is inducible, AmpC type but less commonly seen than with ...
6 de sept. de 2017 · Introduction. Morganella morganii (previously known as Proteus morganii), a Gram-negative bacillus of the Enterobacteriaceae family is part of the normal gastrointestinal flora of humans and other mammals. 1, 2 Infections associated with this pathogen are less frequently acquired in non-hospital settings and in healthy individuals. M. morganii may be involved in soft tissue infections, e.g ...
14 de jun. de 2022 · Conclusão. A bactéria Morganella morganii, embora seja um patógeno oportunista clínico incomum, não pode ser negligenciada. O espectro de doenças é amplo, desde infecções nosocomiais a infecções perinatais que podem ser preocupantes devido à resistência aos antibióticos β-lactâmicos. Autor: Pablo Wilson.

1 de oct. de 2021 · 1. Introduction & objectives. Morganella morganii is a member of the Enterobacteriaceae family (genus Morganella), discovered in 1906 by Morgan et al. from a pediatric fecal culture. It is a Gram-negative, rod-shaped, facultative anaerobic bacillus divided into two subspecies, morganii and sibonii [1].Previously classified as Proteus morganii, it belongs to human gut commensal microbiota.
16 de nov. de 2021 · Table 1. Morganella morganii strains used in this study. We used API 20E strips (Biomérieux, Geneva, Switzerland) to determine the capability to ferment trehalose. To assess if the M. morganii cheese isolates show hemolytic activity, we streaked them on Trypticase Soy agar plates containing 5% sheep blood (bioMérieux).
