A case of Reiter disease in a HLA B27 positive man with urethritis followed by polyarthritis is reported. During the disease, serologic conversion for Yersinia enterocolitica type 9 was detected as well as positive serologic tests for Shigella flexneri and Chlamydia. The features of reactive arthritis related to Yersinia and the etiologies of Reiter disease are recalled.

Background: The shift to more environmentally sensitive agricultural practices over the last several decades has changed farmland landscapes worldwide. Changes including no-till and retaining high biomass mulch has been coincident with an increase in rodent pests in South Africa, India, South America and Europe, indicating a possible conflict between conservation agriculture (CA) and rodent pest management. Research on effects of various crop management practices associated with CA on pest rodent population dynamics is needed to anticipate and develop CA-relevant management strategies.

To explore the application of up-conversing phosphor technology (UPT) to detect pathogenic organisms in the air. The performance of UPT was verified with , and as simulated strains, including stability, specificity, sensitivity and response time tests; Air particle sampler is used to collect air samples in the field microenvironment test chamber, and UPT is used for detection. At the same time, compared with the traditional culture method, the practicability of UPT is verified.

Piscibactins and photoxenobactins are metallophores and virulence factors, whose biosynthetic gene cluster, termed , is the most prevalent polyketide synthase/non-ribosomal peptide synthetase hybrid cluster across entomopathogenic bacteria. They are structurally similar to yersiniabactin, which contributes to the virulence of the human pathogen . However, the -derived products feature various chain lengths and unusual carboxamide, thiocarboxylic acid, and dithioperoxoate termini, which are rarely found in thiotemplated biosyntheses.
