Background: Phytate is an anti-nutritional factor in plants, which catches the most phosphorus contents and some vital minerals. Therefore, Phytase is added mainly as an additive to the monogastric animals’ foods to hydrolyze phytate and increase absorption of phosphorus. Objectives: Y. intermedia phytase is a new phytase with special characteristics such as high specific activity, pH stabilit...

Yersinia enterocolitica and related Yersinia species share many temperature-dependent biological attributes. The present report documents temperature-dependent production of a bacteriocin-like substance only among Yersinia strains which ferment L-rhamnose, raffinose, and melibiose and which have been tentatively designed Y. intermedia. When tested by the "lawn-spotting" technique at 25 and 37 d...

The species Yersinia intermedia is a member of the genus Yersinia which belongs to the Enterobacteriaceae family. This species is divided into eight biotypes, according to Brenner's biotyping scheme. This scheme relies on five tests (utilization of Simmons citrate and acid production from d-melibiose, d-raffinose, alpha-methyl-d-glucoside [alphaMG], and l-rhamnose). The collection of the French...

Crossbred pigs (n = 96, BW = 7.5 kg) were used in a 5-wk trial to determine the effectiveness of supplemental Natuphos phytase in improving the bioavailabilities of P and other nutrients in a semipurified diet with soybean meal as the only P source in the basal diet. Two available P (aP) levels (.05 and .16%) and five phytase levels (0, 350, 700, 1,050, and 1,400 units/kg of diet) were used in ...

The antigenic scheme of Wauters and co-workers was applied to serotype a total of 585 strains of Yersinia enterocolitica, 43 strains of Yersinia kristensenii, 40 strains of Yersinia frederiksenii, and 25 strains of Yersinia intermedia. The O antigens 11,23; 11,24; 12,25; 12,26; and 28 were exclusively associated with Y. kristensenii. O antigen 16 was associated with Y. kristensenii and Y. frede...

In a previous study, we demonstrated that the amount of interleukin (IL)-8 mRNA expressed by human gingival fibroblasts stimulated with lipopolysaccharide (LPS) from Prevotella intermedia ATCC 25611 is increased by pre-treatment with beta or gamma interferon (IFN-P or -y). In the present study, we identified the regulatory effects of these IFNs on IL-8 mRNA expression and IL-8 production by hum...

Since May 1983, our laboratory has, upon request, cultured stools for Yersinia spp. by using direct plating on cefsulodin-irgasan-novobiocin agar and a 3-week cold enrichment procedure. We isolated bacteria identified as Y. intermedia from six adult patients. All isolates were recovered only by the cold enrichment procedure and misidentified as Y. enterocolitica by the API 20E system (Analytab ...

Background: Bacterial resistance to the commonly used antibacterial agents is an increasing challenge in the medicine, and a major problem for the health care systems; the control of  their spread  is a constant challenge for the hospitals. Objectives: In this study, we have investigated the antimicrobial activity of the Zinc Oxide nanoparticles against clinical sample; Yersinia intermedia bact...
