Hereditary ochronosis in very few cases has been examined electron microscopically or histochemically. In this disease homogentisic acid, a normal intermediary of tyrosine metabolism, forms in excessive amounts. This is believed to be due to absence or defective activity of homogentisic acid oxidase, an enzyme system necessary to break the benzene ring and to further break it down to fumaric and acetoacetic acids. Ochronotic pigment, a polymerized form of homogentisic acid, deposits mainly in mesenchymal tissues. There has been a question whether the pigment originates from the collagenous tissues, or deposits passively, where in contrast to melanin it induces degenerative changes.

AbstractThe paper examines epistemological problems behind a recent study claiming to provide a synthesis of a vocal sound from the mummified remains of a man named Nesyamun and behind racial designations in Egyptian mummy studies more generally. So far, responses in the media and academia concentrated on the ethical problems of these studies, whereas their theoretical and methodological backgrounds have been rarely addressed or mentioned only in passing. It seems that the media reaction has targeted the synthesis of a sound rather than other, equally problematic, assumptions found in Egyptian mummy studies. By focusing on the epistemological problems, it will be demonstrated that the issues of greatest concern are endemic to a general state of a considerable part of the discipline of Egyptology and its unreflective engagement with the material remains of the past, especially human remains.

The aim of the research was an assessment of the effect of the Lactiplantibacillus plantarum SCH1 strain isolated from ecological raw fermented pork roast on pH, redox potential, nitrites, and nitrates content, L a* b* color parameters, total heme pigments content, nitrosyl myoglobin concentration, as well as the microbiological quality and sensory traits of cooked sausages produced from mechanically separated poultry meat (MSPM), cured with a lower sodium nitrite level (NaNO2 50 mg/kg) after production as well as after storage (1 and 3 weeks of storage). The biochemical identification of the Lactobacillus bacteria after storage was also performed. Tests were performed in two sausage treatments: C—control sausage made from MSPM and L—sausage made from MSPM inoculated with L. plantarum at approx. 107 cfu/g. No negative effect of using the L. plantarum SCH1 strain on the physical and chemical MSPM sausage features was found. The treatment with L. plantarum SCH1 was of better microbiological quality after 3 weeks of storage. The sausages with L. plantarum SCH1 kept good sensory quality while the control treatment was spoiled after storage.

Insight Into

Background: S. enterica subsp. houtenae has been rarely documented, and very limited genomic information is available. This report describes a rare case of primary extraintestinal salmonellosis in a young roe deer, associated with Salmonella enterica subsp. houtenae. Methods: A traditional cultural-based analysis was carried out from the contents of a neck abscess; biochemical identification and PCR assay were performed to isolate and identify the pathogen. Through whole-genome sequencing (WGS), multilocus sequence typing (MLST), core genome MLST (cgMLST), and the Salmonella pathogenicity islands (SPIs) survey, resistome and virulome genes were investigated to gain insight into the virulence and antimicrobial resistance of S. houtenae. Results: Biochemical identification and PCR confirmed the presence of Salmonella spp. in the swelling. The WGS analysis identified Salmonella enterica subspecies houtenae serovar 43:z4,z23:- and ST 958. The virulence study predicted a multidrug resistance pattern with resistance shown against aminoglycosides, tetracycline, beta-lactamase, fluoroquinolones, fosfomycin, nitroimidazole, aminocoumarin, and peptide. Fifty-three antibiotic-resistant genes were identified. No plasmids were detected. Conclusion: This study demonstrates the importance of continuous surveillance of pathogenic salmonellae. Biomolecular analyses combined with epidemiological data can provide important information about poorly described Salmonella strains and can help to improve animal welfare.
