Histidine Decarboxylase Activity

We have studied the histidine decarboxylase activity in 118 strains of bacteria isolated from commercial samples of Spanish semi-preserved anchovies. The lysine and ornithine qualitative decarboxylase activity was also studied. The microorganism that presented the highest histamine activity was Morganella morganii, with 2123.26 ± 414.00 ppm of histamine after 24 h of incubation at 37°C. Two strains of Bacillus spp. and a strain of Staphylococcus xylosus were isolated with the capacity to form 10.54 and 110.00 ppm of histamine, respectively. However, the histidine decarboxylase activity of Bacillus spp. is not likely to be significant to human health. The microbic species with capacity to form histamine and those with capacity to form other biogenic amines were similar. Therefore, the prevention of the proliferation of microorganisms able to form histamine would also mean avoiding amine accumulation that leads to histamine food poisoning. The Niven medium was an efficient test to valutate the histamine production of isolated strains after an incubation of 24 h at 37°C and using a backwards technique for quantification and detecting the false positives. This incubation time should be longer (48 h) when Bacillus is detected, with the finality to eliminate false negatives on the initial screening. The application of the enzymic technique for histamine quantification was excellent. In our research, we have observed that the number of microorganisms is an important factor in the accumulation of histamine, but other factors exist which also influence such accumulation, probably depending on the kind of enzyme decarboxylase.

Test Tissue

Several rat tissues decarboxylate C14 l-histidine and bind the resulting histamine in stable form. The pyloric portion of the stomach is by far the most active. Pretreatment of the rats with cortisone appears to reduce the histamine-binding activity of most tissues while prior adrenalectomy increases it. The stomach is the exception; here the reverse is true. Using rat lung as a test tissue, it was found that prednisone, prednisolone and 9-α-fluorohydrocortisone appear to be more active than cortisone or hydrocortisone in inhibition of histame bininding. The mechanism of this reduction of histamine-binding activity of rat lung involves the loss of extractable histidine decarboxylase activity.

Histidine Decarboxylase Activity

ABSTRACT Filipendula ulmaria, also known as meadowsweet, is an herb; its extract was examined for the prevention of histamine production, primarily that caused by contaminated fish. The efficacy of meadowsweet was assessed using two parameters: inhibition of Morganella morganii histidine decarboxylase (HDC) and inhibition of histamine accumulation in mackerel. Ellagitannins from F. ulmaria (rugosin D, rugosin A methyl ester, tellimagrandin II, and rugosin A) were previously shown to be potent inhibitors of human HDC; and in the present work, these compounds inhibited M. morganii HDC, with half maximal inhibitory concentration values of 1.5, 4.4, 6.1, and 6.8 μM, respectively. Application of the extracts (at 2 wt%) to mackerel meat yielded significantly decreased histamine accumulation compared with treatment with phosphate-buffered saline as a control. Hence, F. ulmaria exhibits inhibitory activity against bacterial HDC and might be effective for preventing food poisoning caused by histamine.

Histidine Decarboxylase Activity

The distribution of mast cells in muscle and liver of dystrophic mice was studied; histamine and histidine decarboxylase activity was also measured in the same tissues. Mast cells were significantly more numerous in dystrophic muscles. On the other hand, very few cells could be counted in the liver of either control or dystrophic animals. Histamine concentration was higher in muscle and liver of dystrophic mice; no visible increase in histidine decarboxylase activity could be measured by the methods used. It is concluded that histamine-binding capacity is increased in some tissues of dystrophic mice.
