“…It has been implicated in septicaemia caused by contaminated intravenous fluids, wound infections, bacteraemia, urinary tract infection, brain abscess and meningitis (Pien, Martin, Hermans and Washington 1972). Evidence for pathogenicity in animals other than man is scant and mainly confined to experimental situations involving laboratory animals (Muraschi, Friend and Bolles 1965;Bottone and Schneierson 1972 ;Meyers, Bottone, Hirschman and Schneierson 1972;Dutkiewicz 1976).…”

Summary During a 20 month period Enterobacter agglomerans was isolated from 17 cases of equine abortion. In 8 cases E agglomerans was isolated in pure culture and in 9 cases it was isolated in mixed culture from the foetus and/or foetal membranes. Fifteen cases had histological evidence of foetal infection and/or placentitis. The occurrence of E agglomerans in pure culture, associated with inflammatory lesions in the foetus and foetal membranes, suggests it to be a cause of abortion in mares. Résumé Durant une pêriode de 20 mois Enterobacter agglomerans fut isolé dans 17 cas d'avortement équin. Il s'est agi de cultures pures pour 8 cas et de cultures mixtes pour 9 cas à partir du foetus et (ou) des enveloppes. Dans 15 cas on put établir la preuve d'une infection foetale et (ou) placentaire. L'existence d'E agglomerans dans des cultures pures, en association avec des lésions foetales et des enveloppes donne à penser qu'il est cause d'avortement chez la poulinière. Zusammenfassung Während einer Zeit von 20 Monaten konnte Enterobacter agglomerans bei 17 Fällen von Verwerfen der Stute isoliert werden. In acht Fällen wurde E agglomerans in Reinkultur, in neun Fällen in Mischkultur aus dem Foetus und/oder den Eihäuten isoliert. In fünfzehn Fällen ergab die histologische Untersuchung eine Infektion des Foeten oder eine Placentitis. Das Vorkommen von E agglomerans in Reinkultur, zusammen mit entzündlichen Läsionen im Foetus oder in den foetalan Häuten lässt vermuten, dass der Keim als Abortursache bei der Stute in Frage kommt.

“…Some of the inhibitors were chemically characterized such as pantocin B, and genes involved in pantocin B production were determined and mutants complemented[11]. Their relationship to clinical isolates of Enterobacter agglomerans [12] has put legal restrictions on their application as control agents for fire blight. A recent commercial application of Pseudomonas fluorescens strain A506 has introduced the use of another species[5].…”

In order to find reasons for the absence of fire blight in most countries of the Southern hemisphere, bark samples from apple and pear trees in orchards of the Western Cape region in South Africa were extracted for bacteria which could be antagonistic to Erwinia amylovora. Screening was done in the late growth season and mainly Gram-positive bacteria were isolated. Approximately half of them produced growth inhibition zones on a lawn of E. amylovora. Most isolates were classified as Bacillus megaterium by microbiological assays and in API 50 test systems. They were visualized in the light microscope as non-motile large rods. These strains may not be responsible for the absence of fire blight in orchards, but they may indicate unfavourable climatic conditions for Gram-negative bacteria including E. amylovora. They may reduce the ability of E. amylovora to establish fire blight and could also be useful for application in biological disease control.

Erwinia carotovora ssp. atroseptica SCRI1043 is a plant pathogenic bacterium. Many species of enterobacteria including Erwinia sp. can induce the onset or the progression of opportunistic or persistent infections in humans. The existence of these bacteria within different ecological niches is related to their significant adaptive potential. The triggering of adaptive reactions, which are needed for bacterial persistence, is controlled in many cases by intercellular communication; hence, the ability to survive under unfavourable conditions is regulated in a cell-density-dependent manner. In this study, we showed that, during starvation of E. carotovora ssp. atroseptica SCRI1043, the initial stage of the response to stress was stabilization of the density of culturable cells in the range 10(6)-10(7) CFU mL(-1). The number of culturable cells increased (up to approximately 10(6) CFU mL(-1)) when cultures were inoculated at a low cell density (10(3)-10(5) CFU mL(-1)), and at the same time, acylhomoserine lactone (AHL)-dependent quorum sensing was activated. Our results showed that the regulation of cell density in starving populations of E. carotovora ssp. atroseptica SCRI1043 occurred and this regulation was carried out with the involvement of the cell-to-cell communication.
