What is pantoea SPP?
Pantoea spp. is an opportunistic pathogen and rarely causes disease in healthy individuals. Infections caused by Pantoea spp. have been reported in samples obtained from cotton swabs, intra-arterial devices as well as plants and plant material [3].
Is pantoea Gram positive or negative?
gram-negative
Pantoea agglomerans (formerly Enterobacter agglomerans) is a gram-negative aerobic bacillus in the family Enterobacteriaceae. All species of the genus Pantoea can be isolated from feculent material, plants, and soil (2), where they can be either pathogens or commensals (12). Within the genus, P.
What is pantoea Septica?
Background: Pantoea septica is a facultative anaerobic gram negative motile bacillus, member of the Enterobacteriaceae family. Frequently associated with plants, rarely causes human infectious, was first isolated in 2010.
Is pantoea Agglomerans lactose fermenter?
Pantoea bacteria are yellow pigmented, ferment lactose, are motile, and form mucoid colonies. Some species show quorum sensing ability that could drive different gene expression, hence controlling certain physiological activities.
Where is pantoea found?
and Pantoea spp. are common inhabitants of the gastrointestinal tract of humans and other mammals, and they can be found in water, sewage, soil, plant material, and foods. Even the more common human isolates, E. cloacae and E.
How do you get pantoea bacteria?
Abstract. Pantoea agglomerans, a bacterium associated with plants, is not an obligate infectious agent in humans. However, it could be a cause of opportunistic human infections, mostly by wound infection with plant material, or as a hospital-acquired infection, mostly in immunocompromised individuals.
What is pantoea Dispersa?
Pantoea is a genus of Gram-negative bacteria of the family Enterobacteriaceae that was recently separated from the Enterobacter genus. They have also recently been shown to cause infections in humans [1,2,3,4,5,6].
Is Citrobacter a lactose fermenter?
Citrobacter spp. are late lactose fermenters and they grow on MacConkey Agar. Its cultivation is 24 hours, aerobic atmosphere is at 37°C and approximately 20% of clinical isolates are lactose negative.
What causes pantoea Agglomerans?
Wound infection with P. agglomerans usually follow piercing or laceration of skin with a plant thorn, wooden splinter or other plant material and subsequent inoculation of the plant-residing bacteria, mostly during performing of agricultural occupations and gardening, or children playing.
Is pantoea a coliform?
This broadened the number of genera termed total coliforms regularly found in water. The more narrow definition included primarily four genera—Escherichia, Klebsiella, Citrobacter, and Enterobacter—while the inclusion of anaeorgenic lactose fermenters added Kluyvera, Yersinia, Serratia, Hafnia, and Pantoea (10).
What are the symptoms of pantoea?
P. agglomerans is a rare cause of blood, wound, and respiratory and urinary infections which usually present as fever, chills, and disseminated diseases such as septic arthritis, endophthalmitis, endocarditis, and osteomyelitis in the setting of bacteremia. Spontaneous infection can occur in an immunocompromised host.
Where is pantoea Dispersa found?
The representative strain is Pantoea agglomerans. This kind of bacteria inhabits plants, soil and water, and rarely causes human infections. Pantoea dispersa (P dispersa) is a kind of the genus Pantoea, which is often isolated from plants, closely related to Erwinia.

What does high Citrobacter spp mean?
What does it mean if your Citrobacter spp. result is too high? High levels may indicate increased intestinal inflammatory activity. Although considered a commensal, some Citrobacter isolates have virulent toxins, such as Shiga-like toxins, heat-stable toxins, and cholera B toxin B subunit homologs.
What is the arrangement of Citrobacter freundii?
Citrobacter freundii are long rod-shaped bacteria typically 1-5 μm in length [1]. Most C. freundii cells are surrounded by many flagella used to move about, but a few are non-motile. Its habitat includes the environment (soil, water, sewage), food, and the intestinal tracts of animals and humans [1].
How do you get Citrobacter infection?
In patient with Citrobacter infections, the bacteria can be transmitted vertically from mother or horizontally from carriers or other hospital sources (14). The infection may occur as sporadic cases or nosocomial outbreaks.
What causes Citrobacter infection?
Environments known to contain Citrobacter Citrobacter are found in a variety of environmental sources, including soil and water, and in the human intestines. They are rarely the primary source of illness, though some strains can cause infections of the urinary tract, sepsis, and infant meningitis.
