  • The study assessed the validity of the Chinese version of the Patient Activation Measure (PAM-13-C) specifically for individuals with chronic spinal cord injury, involving 284 participants from a rehabilitation center and social media.
  • Results indicated that the PAM-13-C had strong internal consistency and reliable test-retest performance, confirming its effectiveness in measuring patient activation.
  • The findings suggest that PAM-13-C is a valid tool for evaluating the engagement of patients with spinal cord injuries in China, with minor floor and ceiling effects reported.

Type 1 fimbria, the short hair-like appendage assembled on the bacterial surface, plays a pivotal role in adhesion and invasion in . The type III secretion system (T3SS), another bacterial surface appendage, facilitates 's replication by delivering effectors into host cells. Our previous research demonstrated that T3SS protein EseJ inhibits adhesion and invasion of by suppressing type 1 fimbria.

Type III secretion system (T3SS) facilitates survival and replication of . Identifying novel T3SS effectors and elucidating their functions are critical in understanding the pathogenesis of T3SS effector EseG and EseJ was highly secreted when T3SS gatekeeper-containing protein complex EsaB-EsaL-EsaM was disrupted by EsaB deficiency. Based on this observation, concentrated secretomes of Δ strain and ΔΔ strain were purified by loading them into SDS-PAGE gel for a short electrophoresis to remove impurities prior to the in-the gel digestion and mass spectrometry.

Article Synopsis
  • Edwardsiella ictaluri is a harmful bacteria that causes diseases in channel catfish, leading to big money losses for fish farmers in China.
  • Scientists created a weaker version of this bacteria by changing some of its genes, making it unable to infect cells properly, and it can be used as a vaccine.
  • The new vaccine worked really well, keeping 83.61% of vaccinated fish alive after exposure to the harmful bacteria, compared to only 33.33% survival in unvaccinated fish.

The type III secretion system (T3SS) of plays a crucial role in its pathogenesis. Our previous study indicated that the T3SS effector protein EseJ inhibits the bacterium's adhesion to epithelioma papillosum cyprini (EPC) cells, while the mechanism of the inhibition remains elusive. In this study, we revealed that EseJ negatively regulates the gene, as demonstrated by comparative transcription analysis of Δ and wild-type (WT) strains.

The type III secretion system (T3SS) is one of the most important virulence factors of the fish pathogen It contains three translocon proteins, EseB, EseC, and EseD, required for translocation of effector proteins into host cells. We have previously shown that EseB forms filamentous appendages on the surface of , and these filamentous structures mediate bacterial cell-cell interactions promoting autoaggregation and biofilm formation. In the present study, we show that EseC, but not EseD, inhibits the autoaggregation and biofilm formation of At 18 h postsubculture, a Δ strain developed strong autoaggregation and mature biofilm formation, accompanied by enhanced formation of EseB filamentous appendages.

Background: Wounded personnel who work at sea often encounter a plethora of difficulties. The most important of these difficulties is seawater immersion. Common medical dressings have little effect when the affected area is immersed in seawater, and only rarely dressings have been reported for the treatment of seawater-immersed wounds.

Natural killer lysin (NK-lysin), produced by cytotoxic T lymphocytes and natural killer cells, is a cationic antimicrobial peptide that has a broad antimicrobial spectrum, including bacteria, viruses, and parasites. Nevertheless, the implication of NK-lysin in the protection against bacterial infection is not aware in common carp. In this study, six different NK-lysin genes (nkl1, nkl2, nkl3, nkl4, nkl5 and nkl6) were identified in the common carp genome.

The type III secretion system (T3SS) plays a crucial role in the pathogenesis of many Gram-negative bacteria, including , an important fish pathogen. Within the T3SS, there are three proteins (EsaB/EsaL/EsaM) that are homologous to proteins present in many other bacteria, including SpiC/SsaL/SsaM in , SepD/SepL/CesL in enteropathogenic (EPEC) and enterohemorrhagic (EHEC), and YscB/YopN/SycN in EsaL was found to interact with both EsaB and EsaM within the bacterial cell, as revealed by a coimmunoprecipitation assay. Moreover, EsaM is required for EsaB stability, and the two proteins interact with each other.

Type III secretion system (T3SS) is a large macromolecular assembly found on the surface of many pathogenic Gram-negative bacteria. Edwardsiella tarda is an important Gram-negative pathogen that employs T3SS to deliver effectors into host cells to facilitate its survival and replication. EseB, EseC, and EseD, when secreted, form a translocon complex EseBCD on host membranes through which effectors are translocated.

Edwardsiella tarda is an important Gram-negative pathogen that employs a type III secretion system (T3SS) to deliver effectors into host cells to facilitate bacterial survival and replication. These effectors are translocated into host cells through a translocon complex composed of three secreted proteins, namely, EseB, EseC, and EseD. The secretion of EseB and EseD requires a chaperone protein called EscC, whereas the secretion of EseC requires the chaperone EscA.

Flavobacterium columnare is an important bacterial pathogen of freshwater fish that causes high mortality of infected fish and heavy economic losses in aquaculture. The pathogenesis of this bacterium is poorly understood, in part due to the lack of efficient methods for genetic manipulation. In this study, a gene deletion strategy was developed and used to determine the relationship between the production of chondroitin lyases and virulence.
