Shewanella putrefaciens syn.

The largemouth bass Micropterus salmoides is an economically important aquaculture species in China, and its production has increased rapidly in recent years. Although Shewanella putrefaciens is known to infect several fish species, its role in infecting M. Here, we isolated a gram-negative bacterial strain termed XX from farmed largemouth bass. Based on the results of 16S rRNA sequencing and phylogenetic analyses, the isolate was identified as S. The virulence of XX was dependent on water temperature, such as the LD 50 values were 4. The results of an antibiotic resistance test showed that XX was sensitive to kanamycin, cefotaxime, doxycycline, sulfamethoxazole, florfenicol, tetracycline, and gentamicin; showed intermediate susceptibility to streptomycin, ampicillin, and norfloxacin; and was resistant to nalidixic acid and penicillin. XXinfected fish showed clinical symptoms typical of S.

Type strain:. Culture col. Strain history: CIP. Shewanella putrefaciens 95 is an aerobe, mesophilic, motile human pathogen that was isolated from Butter. Note that changes will be reviewed and judged. If your changes are legitimate, changes will occur within the next Bac Dive update.

What are isolation sources categories?

It also has an even greater problem for the food industry due to its ability to form film on food processing equipment that is made mainly of steel, s. putrefaciens.

Shewanella putrefaciens is a Gram-negative pleomorphic bacterium. It has been isolated from marine environments, as well as from anaerobic sandstone in the Morrison Formation in New Mexico. It is also one of the organisms associated with the odor of rotting fish, as it is a marine organism which produces trimethylamine hence the species name putrefaciens, from putrid. In both solid and liquid media, S. On solid media, the colonies are round, fast-growing, and pink.

Shewanella putrefaciens is a gramnegative, facultatively anaerobic, rod shaped bacterium. It belongs to the class of the Gammaproteobacteria and was first described in The bacterium is a rare oppurtonistic human pathogen associated mainly with intra-abdominal as well as skin and soft tissue infections. However, it has also been reported in association with more severe diseases such as pneumonia, intracerebral and ocular infections and endocarditis. In these cases the clinical courses are often associated with underlying, predisposing diseases and risk factors. For successful treatment of S. Since multiple resistances to antibiotics are described, the results of the antimicrobial susceptibility testing must be considered for effective therapy as well. Furthermore, a main challenge in clinical practice is the accurate microbiological identification, and especially the correct differentiation between S. Under certain circumstances, Shewanella -infections can have severe, sometimes even fatal consequences. Therefore, we decided to present the current state of knowledge as well as further aspects with regard to future diagnostics, therapy and research.

S. putrefaciens

Shewanella putrefaciens is a bacteria that is found mainly in marine environments. It is a gram negative bacteria, meaning it does not dye during gram staining, which usually indicates a stronger antibiotic resistance. It is also a facultative anaerobe, meaning it can undergo aerobic respiration when oxygen is present, and can reduce iron and magnesium metabolically. Because of this Shewanella putrefaciens can reduce Uranium and create uranium deposits fredrickson. Sheweanella putrefaciens grows quickly on both solid and liquid media and is recognizable for its pink color. Shewanella putrefaciens was first isolated from dairy products in by Derby and Hammer. Shewanella putrefaciens can be found in freshwater, brackish, and salt water ecosystems. Many healthy marines animals are contaminated with Shewanella putrefaciens only to have it be realized when food caught by seafood industries spoils due to the bacterias presence. In freshwater animals, and in particular fish species of trout, the bacteria has been shown to cause disease.

L-sorbose as carbon source SBE. It is important to note that Shewanella can show resistance to imipenem by secreting an oxacillinase. XX also showed complete resistance to both nalidixic acid and penicillin, Therefore, these anti-infection agents should be withdrawn from the therapeutic plan of fish infected by S. Nosocomial peripancreatic infection associated with Shewanella xiamenensis. Cureus 12 5 , e Tissue degeneration was likely caused by bacterial toxins. Scand J Infect Dis. Qamar, A. Shewanellae strains were identified as S. Likewise, this bacterium, along with some species of Pseudomonas , is one of the main responsible for the appearance of anomalous odors. Benaissa, E.

Cerebellar abscess caused by Shewanella putrefaciens. Bacteriology of butter. Biochemical and pathogenic properties of Shewanella alga and Shewanella putrefaciens. Then, one or two colonies of each strain were picked and grown in 10 mL tubes of tryptic soy broth Oxoid Ltd. Only two ORFs with a high percentage of identity to known plasmid proteins were identified, while the rest of the ORFs belonged to hypothetical or unknown proteins. Sample from Food Industry: food product minimum 25 grams, in suitable protected packaging. XJ contributed to conception and design of the study and wrote the first draft of the manuscript. Medium recipe at Media Dive. We examined antimicrobial resistance and susceptibility patterns of XX by measuring the diameter of the zone of inhibition around each antibiotic disc. Cefazolin 1 g intravenously every 8 h was empirically started on the same day for persistent fever.
