Background: Thailand's population is currently the third most rapidly aging in the world, with an estimated 20 million ageing population by 2050. Sustainability of the family based long-term care model is challenged by the chronic burden on family caregivers and by smaller family sizes. We aimed to introduce a new service model, Community Integrated Intermediary Care (CIIC), TCTR20190412004, including free of charge intermediary care services at CIIC centers in the local community, to help older adults whose caregivers are temporarily unable to sustain care at home.

The LytR family of cell envelope-associated transcriptional attenuators in bacteria has been brought into focus of scientific interest on the expression of various virulence factors, as well as bacterial cell envelope maintenance. However, this protein of Streptococcus pyogenes has been only described as cell surface-associated protein, and its function is completely unknown. We created lytR mutant strains from two independent S.

The virulence of Streptococcus pyogenes depends on proteins that are produced by this bacterium. The production of virulence proteins depends on environmental factors, and two-component regulatory systems are considered to be involved in sensing these factors. One of the environmental factors is acid stimuli.

Article Synopsis
  • A study analyzed 110 Streptococcus dysgalactiae subsp. equisimilis isolates using PCR to detect the presence of the SICG gene, finding it in 19 strains (17%).
  • Of these 19 strains, 11 (55%) were linked to invasive diseases, with all strains displaying group G carbohydrate and most having specific emm types (stG643 and stG2078).
  • While no direct link was found between the presence of the SICG gene and the severity of infection, further research could clarify its role in the virulence of S. dysgalactiae infections.
