Kim et al., 2007

Shewanella haliotis, a species of rod-shaped, Gram-negative, facultatively anaerobic bacteria, was first isolated from the gut microflora of abalones (large edible sea snails) collected from the ocean near Yeosu, South Korea, by Kim et al. in 2007. Further studies showed the cells to be catalase- and oxidase-positive. [1] The species epithet haliotis is a reference to the genus name of abalones, Haliotis .

Contents

The genus Shewanella had been previously named in 1985 by MacDonell and Colwell in honor of Scottish microbiologist James M. Shewan, for his work in fisheries microbiology. [2]

Characteristics

A sample colony of S. haliotis was isolated from an abalone. It was pink-orange in colour, grew at 42 °C in the pH range 5–11 (with optimum pH being 7). It was found to be positive for malate as a carbon source, and negative for mannose and glucose use. The strain was resistant to both penicillin and vancomycin. [3]

The route of Shewanella infection is associated with direct contact with the organism through seawater or ingestion of raw seafood, causing severe soft tissue infection. One case of infection was found to be susceptible to ciprofloxacin (0.25 mg/l), piperacillin-tazobactam (1.0 mg/l), ceftriaxone (1.0 mg/l), and meropenem (0.38 mg/l). The patient had fever for the first 2 days of hospitalization. After 2 weeks of treatment, the antimicrobial drug was switched to oral ciprofloxacin; treatment was continued after dressing and debridement of the fasciotomy wound. [4]

Mycobacterium caprae is a species of bacteria in the genus Mycobacterium and a member of the Mycobacterium tuberculosis complex. The species is named after the caprines, the organisms from which M. caprae was first isolated. Prior to 2003, the species was referred to as Mycobacterium tuberculosis subsp. caprae. It is also synonymous with the name Mycobacterium bovis subsp. caprae.

<i>Cronobacter sakazakii</i> Species of bacterium

Cronobacter sakazakii, which before 2007 was named Enterobacter sakazakii, is an opportunistic Gram-negative, rod-shaped, pathogenic bacterium that can live in very dry places. The majority of Cronobacter sakazakii cases are adults but low-birth-weight preterm neonatal and older infants are at the highest risk. The pathogen is a rare cause of invasive infection in infants, with historically high case fatality rates (40–80%).

<i>Arcanobacterium</i> Genus of bacteria

Arcanobacterium is a genus of bacteria. They are gram-positive, non–acid fast, nonmotile, facultatively anaerobic, and non–endospore forming. They are widely distributed in nature in the microbiota of animals and are mostly innocuous. Some can cause disease in humans and other animals. As with various species of a microbiota, they usually are not pathogenic but can occasionally opportunistically capitalize on atypical access to tissues or weakened host defenses.

Exiguobacterium is a genus of bacilli and a member of the low GC phyla of Firmicutes. Collins et al. first described the genus Exiguobacterium with the characterization of E. aurantiacum strain DSM6208T from an alkaline potato processing plant. It has been found in areas covering a wide range of temperatures (-12 °C—55 °C) including glaciers in Greenland and hot springs in Yellowstone, and has been isolated from ancient permafrost in Siberia. This ability to survive in varying temperature extremes makes them an important area of study. Some strains in addition to dynamic thermal adaption are also halotolerant, can grow within a wide range of pH values (5-11), tolerate high levels of UV radiation, and heavy metal stress.

Wautersiella is a genus of bacteria most closely related to Empedobacter brevis in the family Weeksellaceae and the order Flavobacteriales. Originally described in 2006 by Kämpfer et al. based on 26 clinical isolates from Belgium that shared 94-95% homology after 16S ribosomal RNA sequencing. The species described was named Wautersiella falsenii in honor of contemporary microbiologists Belgian Georges Wauters and Norwegian Enevold Falsen.

Elizabethkingia miricola is a species of bacterium isolated from condensation water in Space Station Mir, related to Elizabethkingia anophelis, the cause of the 2016 outbreak of Elizabethkingia anophelis human infections in Wisconsin that began in early November 2015. The genus name Elizabethkingia honors former United States Centers for Disease Control (CDC) microbiologist Elizabeth O. King, and the specific epithet is derived from combining the Russian name of the space station from which the bacterium was isolated, "Mir" meaning "peace," and the Latin "incola" meaning "inhabitant," yielding miricola, "inhabitant of the Mir space station."
