Histamine-producing bacteria are responsible for scombrotoxin (histamine) fish poisoning, a leading cause of fish poisoning in the United States. We report here the first draft genomes of three histamine-producing Morganella psychrotolerans strains, isolated from tuna and mahi-mahi.

Research background. One of the issues in production fish sauce is legal constraints on concentration histamine produced by bacteria during fermentation because it causes allergic reactions humans. The goal this study was therefore to eliminate final product after establish a practical way enhance quality for consumer safety, manufacturer exportability, and domestic sales. Experimental approach...

Some bacteria decarboxylate amino acids as a means of resisting acid stress. It is mechanism commonly used by in fermented dairy products. The decarboxylation histidine to histamine occurs frequently some types cheese, but high concentrations can be harmful consumers. Not all products are, however, undesirable. GABA, the product glutamate, has positive effects on human health. Although and GABA...

RATIONALE Contact lens storage cases are known to be contaminated by a significant number of bacteria. However, histamine-producing Raoultella species has not been reported to contaminate contact lens storage case. PATIENT CONCERNS A 27-year-old woman with keratoconjunctivitis that developed in the left eye owing to a cosmetic contact lens and poor hygiene was referred to our hospital. The co...

Using incision, excision and dead space wound models in rats, a study was conducted on the effect of histamine on wound healing. Exogenous histamine given either ip or locally was without any effect. Semicarbazide as (histamine synthesis inhibitor) suppressed healing process (breaking strength of skin incision wound), decreased breaking strength and hydroxyproline content of granulation tissue ...

An improved screening plate method for the detection of amino acid decarboxylase-positive microorganisms (especially lactic acid bacteria) was developed. The suitability and detection level of the designed medium were quantitatively evaluated by confirmation of amine-forming capacity using an HPLC procedure. The potential to produce the biogenic amines (BA) tyramine, histamine, putrescine, and ...

Histamine-producing bacteria are responsible for scombrotoxin (histamine) fish poisoning, a leading cause of fish poisoning in the United States. We report here the draft genome sequences of four histamine-producing (HP) Photobacterium kishitanii strains and nine HP Photobacterium angustum strains isolated from tuna.

Histamine-producing bacteria (HPBs) have recently been identified from the marine environment. The identification and characterization of HPBs is important to developing effective mitigation strategies for scombrotoxin fish poisoning. We report here the draft genomes of seven histamine-producing and two non-histamine-producing marine Photobacterium strains.
